I've hated just about every engine swapped RX8 but this I don't mind. High revving and decent power with torque and cheap engine to replace.
Seems very balanced as well I know that engine is light
What about a 1uz
What's to hate about swaps? It's an extremely good chassis with an engine that's prone to earlier failure than older rotaries.
@@dannycobb5052 In my country a lot of engine swapped RX8's end up for sale a month later, I am guessing they used a heavy engine and ruined the handling but I don't know, that's just what I have personally seen in groups and clubs etc that I am in.
And not too much heavier, not too much taller and not too much more pollar moment (Sorry for my bad english)
We should appreciate swapped Rx8’s because it’s keep them on the Road They’re slowly ending up In junk yards keep Rx8’s on the road Guys ! They’re some of the Most beautiful Japanese cars !
No. Rotary or sell it.
@@CaramelColored braindead comment. Most people won't even touch these. How many rx8s can rotary lovers possibly buy?
@@CaramelColored 😆😆So, it's better to see one in a junk yard, than to see one with a swap driving?😆😆
@@seanhenry8030 Yup. Absolutely.
@@CaramelColored LMFAO👍
That sound is more acceptable in an rx8 than a camaro
So true!
Facts sounds good here
Putting an aftermarket exhaust on will do that...
It sounds great anyway!
The Camaro exhaust has a resonator that gives it a deeper tone. They sound totally out of place with an aftermarket exhaust.
I think this is the best non rotary swap option. My engine is still fine but if I find another Rx8 with a blown engine I might do this.
Nice to see other options available. Sound is actually surprisingly good!
This RX8 is like enjoying fine wine at a jazz festival, good times.
LOL perfect!
I’ve been hoping you’d get a chance to drive an LFX swapped RX8, so I’m super happy to see this. Andrew Keisler is amazing to work with and the parts he builds are beautiful. I bought my RX8 new and I’ve been driving it over 15 years. It was time for something new but the more I looked I found all I really wanted was an RX8 that made 100+ more horsepower reliably and was still a great daily driver and track toy. Andrew finished my swap a little over a year ago and I love it.
How much did it add up to cost wise?
@@j.e3336 Sorry, missed this. With everything I did and having Andrew do the swap I have a little over $15k into mine.
@@tiffnjeff excellent deal. I'm looking to pick up an S2 for this swap soon. best car for the $ hands down!
Any issues? I heard the battery randomly drains
@@rc28ify I've seen this as well. The VW forum one in particular it was well documented. Seems to be an issue on cars that sit due to the RX8 electronics and LFX stuff being together
An RX8 doesn't need mad power to be fun, I would even say it shouldn't be paired with massive power. LFX V6 is the perfect swap: 300+ crank hp, 7k+ redline, and nearly the same weight as the Renesis but with tons more down-low torque. Go for it!

I was wondering when people were gonna start using v6 muscle car engines… this is cool
I've often wondered what my RX-8 would be like with my Ford police interceptor 3.7L V6. But I really don't want to lose the heart and soul of the Mazda.
Whenever my 13b msp gives i will swap a 13brew or rebuild the msp with a street port and lighter rotors. Currently sitting at eighty one thousand miles. I would love to do a three rotor, but I can't justify the price range.
The engine has to be from a Mustang, Transit, or F-150.
When I first got mt RX8 I got it for the fact that I love RX8s and I'm not a big Rotary guy. I figured I'd rock the Rotary till it went out then go LFX or LS. But after 4 years. 50k miles. Hours upon hours of heavily spirited Drives alone and with friends, and some track time. I love the Renesis. I think its an awesome engine if you can resist the temptation of more power, and get faster through skill.
My dream build for the RX-8 however would be something worth of directly competing against a 996 GT3. NA 20B with about 300-350whp. Good street oriented suspension wheel and tire setup. Maybe light aero, and the whole car be done in a way that you would think Mazda themselves built it, and looked 100% "stock" even done to the bean counter effect on certain parts.
Could always opt for a 13brew.
@@sofakingdom3076 true but I much prefer a NA Rotary
I've heard nothing but good things about the V6 Camaro but I just don't think I'd allow myself to have a V6 Camaro. But I always thought that that GM V6 would be nice in BMW 3 Series coupe (I have a '92 325 is), a 90s 300zx or these RX8s. I love what you have here.
Another great video. Prop's to Will for the unique setup, it's a lot of work to get something like that going. I'll eventually get my build refined enough to have it reviewed by you guys (hopefully).
Interesting swap. I had an idea to rock that same engine in a Colorado standard cab short bed lowered and badged SS. That is the truck Chevy should have built to replace the Extreme.
Interesting info. I'd like to see a comparison of this versus a REW swap RX-8.
The rev hang is really surprisingly bad in this car. I know the V6 Camaros don't have a problem with rev hang. Any idea why this car is doing it?
this was thoroughly enjoying to watch. some car mounted go pros would have made it absolutely perfect.
Thank you!
I would love for you to interview the guy who built that car and did the swap to see what it entails.
There's a guy that has documented his entire lfx swap on his if you search lfx rx8 it should Pop up, not sure if this one has the stock rear end or not but his he swapped to the IRS from the same Camaro even
Came here for the swap, but the husky 701 in the background caught my eye first!
FE501S I did a Supermotor conversion on ;)
@@TheSlipAnglegreat SM platform. I did a KTM 525 SM conversion and it’s like cheating at Deal’s Gap.
I love the sound of the LLTS and the LfX when they done right.
Something like this is one of my dream cars honestly. Coupe feel but can still haul some kiddos.
I love the RX8, it's basically a bigger miata seeing as the NC shares the same chassis. Nothing is like a rotary...but this setup would be something you could actually drive everyday and not worry about 70s Ferrari level maintenance lol.
I'd prefer a K series built to rev to 8k+ but this is a much more cost effective swap and the character still fits the car. Those V6s sound pretty good and rev high enough. Plenty of power too...the only thing is it looks like it has a lot of rev hang. Wonder how easy it is to tune that out....
Sweet build man!
Great video man and i totally agree with what you said .....the RX8 needs a 20B in it and it will be a fantastic car even NA i think turbo will be insane :)
No doubt!
If Mazda had been a bit more brave by putting a triple rotor in the RX8 it would have been really amazing but I understand why they didn't as the fuel consumption would be even more appalling! I average around 16-17 mpg so a triple rotor might be more like 12-13MPG. And remember when the RX8 was on sale it was competing against cars like the Golf GTI which had around the same power as the RX8 but way better fuel consumption! It's a shame 20Bs are so hard to come by as swap could turn the RX8 into the perfect car (well for me anyway ;-)
@@somecallmetim42 They'll be more affordable in the future with cnc machining becoming more accessible.
@@sofakingdom3076 affordable maybe for people with deep pockets and all the time in the world to tinker like Rob Dahm, for the likes of the rest of of us if you want to start up a production line for reasonably priced 20b’s then please go ahead ;-)
I used to be a hardcore rotor head. Bang for the buck just isn't there anymore. Engines cost exponentially more per hp than almost every option, guzzle fuel, the fumes gag the folks behind you. You ever race one? The heat that gets put into the floor boards and then into you is a serious thing.
1800f egts at wot is a lot of grass fire setting heat in your exhaust. I thought i would regret the change when i switched to pistons but how wrong i was.
I get RX8 swaps but I dont think I would ever describe it as a light car.
Then again, I also own a Mk3 MR2 so that might be a rough comparison. Lol.
I thought about doing an LS Swap RX8, but then the weight is on par with the Vette. May as well buy the Vette in that case. I did a 5.0 Miata swap and stupidly sold it as it was such a fun car. On my first test run I obliterated a SS Chevy truck that kept driving like an idiot. He gave it all it had, but got destroyed by a little red Miata. LOL I plan on doing a LS Miata swap in the future.
Currently putting an LS into an RX8 and I also own a mk3 Mr2 lol so I can maybe help you out in a few months! Just like Biff said, it basically is a corvette power to weight ratio after an LS is swapped in.
Better than rotary? No (although subjective as everyone likes what they like - or doesn't)
Better than a V6 Camaro? by a fucking landslide
*This was a waste of a good series 2 though
flywheel is dual mass and a bit heavy, however the RPM hang is a tuning issue.
Yep the lfx electronic throttle body doesn't shut instantly
@@lappyverbatim6498 there is a map in hptuners you can change to fix it, there have been a few discussions about it on the web
@@poiuytrewq8ff that would be good. I haven't seen anything around. Most discussions I've seen mention that the throttle control is now within torque management and very hard to change.
@@lappyverbatim6498 have a look in the hptuners forums. I also saw a tuner fixing it on yt on a lfx commodore - I can't remember how he fixed it. there is definitely a way to fix the tables to prevent this as good tunes don't suffer the issue. what ecu e39a?
This video continues to peak my interest in an LFX Miata....
Check car throttle v6 miata
@@robersniper Yup, seen it. Jaguar v6 sounds great but doesnt make sense here in the States. There are way more LFXs here, they are cheaper, and make more power.
@@dylanpudiak7963 yeah... Any good v6 is going to get the miata into the ultimate level. Compared to a v8, the power loss is not that big compared to size. Great balance overall!
Check out the video by Grassroots Motorsports that compares a LFX swapped RX8 to a LFX swapped NC Miata.
Hey Quinn, I met a guy at the unofficial Miatas at the Gap 2020 that had an NB with an LFX engine and it was my favorite option out of the ones that I saw there, that is, compared to the four-cylinder turbos and superchargers. I asked him whether he had contacted you, either you had not responded or were not interested in his LFX NB. I'm selling my na and plan to do something with my RX8. The LFX was at the top of my list, but I'd sure hate to lose that sweet transmission on the RX8. Great video hope you can follow up on this RX8.
Oh hmm we never saw it come through. Have him email us at slipanglemedia@gmail.com. I'm curious if a VQ37 could be made to work.
@@TheSlipAngle I'll look up my notes from that trip later this week. : ) I'm ready to sell my NA and may get the RX8 road trip ready in time for this year's Miatas at the Gap event in early August.
Seems like a lightened and balanced flywheel and an ECU remap could fix that rev hang, hopefully for not a lot of $$$...
Good swapping!
Do you shave toe board(firewall)?
The length between toe board to steering rack is too close for not 13B by Mazda.
Interesting choice of engine and pretty unusual as most folks would rather swap in an LS. If the aim is to stay around the same peak power, but do away with rotary engine quirks/headaches, the LFX does seem like the better match to the RX-8 though and more of a lateral move. If it means retaining the same sweet handling then I'm all for it, although the powertrain character does change from peaky to grunty.
This swap job looks SOLID though! No funny stuff while you were driving it?
I don’t know why the guy said 280hp, unless he meant at the wheels. The LFX is rated at 335 at the crank. Sounds like this one has exhaust and intake upgrades which should get at least 10 more, I would think.
@@racerfink he said 288 whp
Awesome content and review as always!! Don’t see many of the Rx8 with this quality. Keep them coming!
as much as i want to agree with you when you said the 13b renisis should have been packaged like a 20b. How do you think it would go over if it burnt 50%more fuel than it already does?? this is coming from an rx8 owner who has dailyed it off and on for years
I just think fuel economy and rotary should never be used in the same sentence. If you try to get good fuel economy out of one you compromise in areas that are more critical IMO.
@@TheSlipAngle this. Can't buy this car worrying about fuel economy
Interesting…. Sounds like a classic I-6
Loved this video I'd like to see you drive other engine swapped Rx8's like LS or k24 as well
Maybe one day!
That rev hang i bet is from the drive by wire, should be able to tune that out, Civic Si’s had that issue in the late 2000’s
They are called CFCO (clutch fuel cut off) tables....
Quinn, if you do decide to pull that Renesis.. why not put it in the Exocet? :D
doesn't the swap makes it top heavy ? 13b is a small engine. How do you balance the car ?
For the same amount of power approx you should look into a greddy turbo kit, the renesis can live well with very little boost like 6psi.
Is greddy even still making it?
@@TheSlipAngle no you need to search for a used one on ebay I think.
There's also a new kit in the works from Ryan Rotary Performance in the UK, you should check them out if you have the time
@@Myosos these stock engines suck. They’re slow and guzzle gas ridiculously.
I too have an LFX, its defiantly different the way they make power feels like a turbo car without a turbo, and the rpms just keep climbing and climbing its a blast with a 6 speed. Truthfully I don't need a 500hp LS motor, when the LFX puts the car down the road faster than the wheels can hold the road lol.
I’ve always wanted to see a bmw swap especially an n54 with some power behind it in an rx8. Rew still the best swap though
I think that’d be cool. The n54 gets a lot of hate. But if you’re going to use one for a swap it’s quite easy to negate the common issues they have
You can tell this guy loves his rx8. Engine swap, sport steeringwheel, radardetector, factory seatbelt :D
that tillett seat is sick
agreed!
This is really cool, definitely a compelling package, but for how much it likely takes to replicate why not just go 350Z? Same power, similar weight, good suspension and steering, similar sound, and probably much cheaper to get into and maintain overall not being a swapped car.
4 doors and seats. Also they could also probably be very similar with pricing
@@MarinatedPasta if you needed 4 seats you could have a g35 for similar money to a 350z. Or even a genesis coupe 3.8. And this definitely cost more to replacate than the cost of a 350z, you could pick a decent one of for 6k or a great one for 12k, and im sure ghe work required to swap the engine, transmission and differential and then getting the electronics to work would be atleast 10k in especially if you are going through a shop not including the cost of the car. So youd probably be into this car atleast 15k. You could almost afford to buy and boost an FRS/BRZ got that money with how cheap they are getting. Its a cool and interesting package but you can have other cars that do the same functions and deliver similar performance for much cheaper. And likely would be easier to mod and maintain the other cars considering they'd still have their factory motor.
Is the traction control on or is it a sport without one?
were you able to keep the battery under the hood?
Sounds great, but doesn’t seem that quick. It might be the camera angle. Good work though.
It's not about being fast all the time. Quinn wouldn't own an s2000 and a Miata if that were the case. I think this build was more about reliability + a great chassis.
@@sdlausen1 I get where you are coming from, but an engine and transmission swop is an awful lot of work for a minimal performance gain. I imagine the V6 changes the balance of the car significantly, so handling will be slightly compromised. I felt the front end feel has changed or maybe he’s not that used to the car. You are left with one great aspect of the car, the taught rigid chassis, but you lose some of the other standard features i.e. revvy engine and rifle bolt gear change. What has this engine swop added to the experience? Each to their own though.
@@Jack-my4mx it added reliability 😂
This will run for half a million miles
@@ArtVandelayOfficial that's the appeal for the ls swap for me as well. My 02 Chevy with an lm7 is sitting at 286,000 miles on the original motor.
I love everything about the rx8 minus the potential reliability problems.
Man I love that Tillett carbon fiber seat, I've used Tillett seats for go kart, where can I get one for car?
interesting and awesome swap, probably got a steal on it. Im curious as to why they chose the LFX over other v6s (ive driven a few base camaros, not bad but my first instinct on a v6 swap is VQ all day).
Probably because the LFX has integrated headers, and will fit without modifying the engine compartment (like shock towers).
Do you believe that the VQ will fit dimensionally in the RX8 with no cutting or fabrication required?
VQ is so space wasting Lfx is a nice compact motor
@@jonathansparrow7336 that’s why I’m asking lmao it wasn’t a rhetorical question
@@davidbeauvais1364 Thanks that’s what i wanted to know
I would love to know the exhaust setup on this car
is there a way to get rid of the rev hang or whatever that is between shifts?
that would take all the fun away imo
Lighter flywheel
Omg this is the exact setup I want 😍
a J-series in this would be sweet
That engine is very light and mounts up to the s2000 transmission. 300HP stock.
@@thedoctormma9433 Don't need a adapter plate.
Sweeter than the lfx? Fk no
How would it cost to do so,etching like this?
I've been watching videos on this recently and this pops up
How much would it cost to do that ive owned an rx8 for long time now it needs engine?
Amazing presentation ❤❤
K20 in Your car Quinn. Turbo if you want serious power. Now that would be a project.
It has 3 sides to each rotor each side is doing what a piston would be doing in a piston engine,(intake,compression,combustion, exhaust), so compare it to a v6, 2 rotors x 3 rotor faces, so not 1.3 liter or 2.6, actually 3.9 liter. Mazda is calling it 1.3 liter being the 2 combustion chambers added together, just as any piston engine is all cylinders combustion chambers added together, but you have to remember, a piston engines cylinders are only on combustion one at a time.
I think the Ginetta G56 uses this engine with a sequential and apparently it's a blast to drive. Not unlike the rx8. Light nimble car with a decent and reliable engine. Very cool build.
It uses the ford's 3,7 v6
To be honest, the engine and the sound is much more suitable for the RX8 than the camaro, love the swap by the way.
This build just gave me such a great idea for a build
Hey this may be a dumb question but, what do you need to swap it? Also how much did it cost to swap?
I agree with the rotary comment. The renesis is just not a ideal engine in the rx8. To heavy a car for the lack of torque the engine produces. I like this swap, it’s different, I would want something that’s more got more revs though.
Do you have any info on the Tillet carbon fiber seat/rails? Looks pretty awesome.
I have one of these, some of you may have seen the silver rx8 at gridlife nola. Everything about it is great. Keisler is great also and always improving this swap.
czcams.com/video/Wnhm-Bit0q0/video.html. Heres a clip of how it sounds at the trackm
Did you do it yourself? Was it difficult?
@@j.e3336keisler automation did the swap for me, but generally id say it should be fairly easy. The swap kit provides everything you need and there is a detailed video series to guide you.
@@_Mike_D_ Oh ok thats nice. Lfx rx8 is definitely on my dream build list. Was is expensive all together? Could you do it under 15k?
@@j.e3336 if you check out the website there are brochures that give you cost. Id like to say 12-16k for everything including a chassis if your doing the work yourself. I think i spent 22k but that included Penske's and some other extras. I flew to Knoxville, hung out with Andrew for a bit and drove the car home. If your in the area ill be at barber oct 1/2 if you want to check a swapped car out.
Turbo 20b sounds nice on paper...but you better have a whole lotta Paper 💸
Fitting that I’m watching this video with 9,000 + views!!!
I mean🤷 if you're on a tight budget it makes sense. I think a vr38 would make more sense if you're using a V6 but also substancially not expensive
VQ37 would be cool
@@TheSlipAngle I found one for 2500$ and almost did a Vq.... But realized I couldn't sleep at night without my BRAPS
Why is it soo difficult to find the 0-60 w/ these swaps :/ I hear Nissan makes a better manual for this operation..albeit a little shorter (or longer?) geared
Looking at used rx8’s how much does something like this cost approximately all in?
Wow it's like it came in it. Sounds amazing too.
I think the answer is Honda J Series v6 with an s2000 tbh. It would be like this car but much better. It's very worth looking into. They take boost well too.
It’s not a stock setup to be RWD at all and the base power levels with J series are not adequate
i really like the sound of the LFX... Got me thinkin
Thanks for the video. I think the ideal swap would be a Honda Civic Type R crate engine. 306HP and 295 lb-ft of torque. It’s what comes in the Ariel Atom now. Problem is you can’t buy one unless you’re ordering it directly from Honda Motorsports for a Honda build. The other engine I’m very interested in is either the older Mitsubishi 4G63T that went in the Evo or the newer Mitsubishi 4B11T that went in the last version of the Evo.
if you're going to 4g63 swap something, you should look into using a Starion or Conquest. They had a 4g65 stock, and that is compatible with the 4g63t internals... ;D
What exhaust system is that? Or who did the custom exhaust if its custom?
Saw some forum posts on an LFX swap. Sounds fun. Looks good. Still shit compared to the scream of the standard engine.
A smooth 9K RPM is always intoxicating...
I have #863 Shinka . Would it be smart for me to swap the engine??
I bet an LS or LT V8 weigh about the same. I'm sure it was a cost factor going with the LFX.
The LS can definitely be light. Nice thing about this is if you find a wrecked V6 Camaro you can just have 1 donor car.
i am 16 and had planed to do this swap if it manages to be cheap when i grow up, unfortunately people are noticing it now and i dont think i would be able to afford it :(
can the original manual transmission used with a Mazda 3 or Mazda 6 engine?
gotta nice sound but probably wouldnt be my first V6 choice to swap
Which V6 would you choose instead?
@@southernclassik something italian could be fun...when did the stop making them ?
@@southernclassik A Ford NA V6 from a Transit van, Mustang, or F-150. Another great option is a Nissan VQ35/37 swap.
hey Quinn, I'm wondering your perspective... should I J32 swap my NB2 or look for an RX8 chassis? I already have a new-in-crate J32A, but my 1.8 runs great and I love the RX8... Please let me know which car you'd prefer and why
It's really hard to say. I guess it depends on what you are really trying to do.
@@TheSlipAngle sorry I should have specified. I'm looking to do drift days, occasional autocross, and spirited back road drives. if I do rx8 I'll keep miata stock power with current suspension/chassis mods
Did you say the lfx motor can go with the rx8 MT?
No, this one has the LFX transmission with it. I haven't heard of being able to adapt it to the stock transmission.
Ill admit, that sounded and looked fun. And not an LS swap! 😆
Definitely enjoyed watching you giving it the beans 😤👍
280 at the wheels? I thought these were supposed to make 320 but not sure if that’s at the wheels or not.
i like it, now i want one.
Dang Quinn about time! Been teasing it on IG for like a month =P
Can't rush the process :P
Here is my burning question. How much does it cost? Is it better than a similar cost vehicle? I love swaps and modded cars but I am trying to remember that a car with a lot of money in mods needs to be better than an OEM car of the same cost.
If you check the shop website they tell you the whole cost it’s about 12500 to do it honestly not that bad
Does anyone have a link to the LSX and MV5 swap kit and install video?

Interesting engine choice...
Does anybody know the exhaust set up on this car? It sounds really good, I’m wondering if is a cat-back for the RX8 or if he custom fitted a Camaro exhaust?
Bloody fast car. The thing digs in and just goes.
Is AC able to fit in there?
Huh, that’s an interesting swap
I gotta 07 GT rx8. Would that swap and set up work in a series one ? Also if anyone knows a reliable rotary shop in Toronto that would be helpful.
Thanks
RX8 with torque I want
it's aight
i feel like they could use this body style and put a v6 in it and it would sale good i love the body style of the 2010 and 11 rx-8 i had one and i miss it . i dont know maybe 280 are 310 hp are even 330 yes thats over kill but that would be fun in this car.
