13b Swapped FB Rx7 Review

- My Thoughts on the 1985 Mazda Rx7 with a 1987 1.3L 13b engine swap, and 5 speed manual transmission:
This is my car. My crowning achievement. The most valuable Item I own. I built this car. I bought it, blew the motor, and was devastated. Over a year later, with the help of online forums and willing friends, My Rx7 now has a 13b engine under the hood.
The 13b Rotary engine is fuel injected, and makes around 145hp. It’s redline is 7800 rpm. That might not seem like a lot, but consider the fact that it’s a 1.3L, and weighs as much as a high school linebacker. Being so small, the engine fits behind the front axel, making the car handle even better.
But what makes this car so great, is the fact that I built it. Without me, this car would be sitting in a junkyard rusting away. To drive a car you built, is a feeling like no other. After months of turning the key and only being disappointed, turning the key and hearing it fire up may be the best sound in the world. I can actually say “Built not bought” not ironically. This car qualifies as a build. Your plasti-dipped wheels and lowering springs, do not.
What did I have to do for the swap? A lot. But it could be worse. The 13b is from a 1987 Mazda rx7. I needed a new engine mount and oil pan to fit the engine into the chassis. New fuel pump, radiator, oil cooler, and fuel lines were needed. The ECU got upgraded to a Mega squirt, along with the engine harness being significantly cut down. A full emissions delete was done to the engine for better efficiency. With a little spray of paint and break cleaner, the 13b works great.

"build your dream car. because life is to short to not drive [it]"
thanks for making this video, really needed to hear that right about now. i'm working on a 13b (S4) swap right now, and i keep watching rotary videos to keep my spirits up while i work on the build. money's super tight - a "rotary specialist" shop screwed me over by not refunding me $5k when they failed to do any work on my car, so i'm basically gonna try to DIY the build. (the engine is going into a non-rotary car, so the swap is a bit difficult)
anyway, i hope the FB with 13b brings you many years of enjoyment, especially knowing that you made it happen! peace :D
That sounds awesome! There were many long nights, nights of doubt, frustration, and anger. But when the 13b finally held an idle on it's own, it was insanely rewarding, by far one of my proudest achievements. I have a whole series on my channel called Rotary life, I'll link you to the episode where I drive it for the first time! czcams.com/video/bfdTxEQOVTM/video.html
Hey I had a first gen long ago but I have a 2nd gen can I put a rx8 motor in my 88 Rx7
Been here since you had the 12a in that thing :) Good to see the swap went well.
same. been following the build since pretty much day one. love it man.
One of life's regrets (sort of). I bought a new 84 GS 12A instead of the first year GSL-SE 13B. However, I still own and drive it today (2021). She's mostly stock, beautiful and fun drive. Best part: Today she's worth more than I paid for her new and continuing to appreciate in value. Still, wish I had an original 13B...
I recently bought a 1984 RX7 GSL with a 12a, it’s my second car at 19 years old and I must say I’ve never been more excited to own an older car
Just recently purchased a 1984 FB after my 1997 miata was destroyed in a car accident. I actually even ordered a set of diamond steelies before I stumbled on your channel lol. Sounds like our cars are going to be twins pretty soon! I'll definitely be keeping up with your channel a lot more from now on. Nice car!
Subscribed! Absolutely love it, and I can't wait to get an FB. I had one about a year ago, but couldn't keep it. Now I have a good job to support it and I'm excited. You're channel and IG page are both super inspiring!
Just earned a new subscriber. Excellent video man. I'm an owner of an Rx8 and currently trading for a 1985 Rx7 12a. I'm actually looking for more information on 12as would love to talk if you got the time
I miss my SA being powered by a 13B, I'm not a fan of the 6 port fuel injected engines, but am a huge fan of the OG 4 port carved 13Bs. The engine that came in my car was from a 76-78 cosmo and had a large street port making 154whp on the dyno, but after 22,000 miles of daily driving and the car sitting in a junkyard for who knows how long, the engine lost oil pressure and locked the front rotor bearing. currently I am almost ready to rebuild the engine (just waiting on modded renesis rotors and resurfaced housings to come back) and the car is running on my stock port 12a in the mean time. Glad to hear you got yours back on the road, good job
great video, planning on buying an rx8( my dream car)
I love your videos on the rx7 i do plan on building an fb with a 13b from an fd. Your videos actually inspired me to do this build even more. I plan on continuing watching your videos and hope i learn more from you. Keep up the good work 👍🏻
Ah man you remind me of hot rodding my old 84 back in 06 keep on rocking the rotary
13b or 12a for reliability ?
Happy to see this thing rolling again 😊
Nice job, I did one back in the day but I did not go fuel injection. I went with a Holley. Ran nice. I know I was happy with it. Iam sure your happy with yours going from But a 12Ato 13b a lot more power.
awesome! did the same with an s5 motor to an '85. swapped the whole front end too.
i love it. love this channel, love the car and love the inspiration/passion you have towards creating your dream
I am glad to see Rose running well :)
Love the channel, in the process of fixing my dream car haha early model SA
So you built a gsl-se with smog delete?
Hats of,feels like the build I have now👌👊
What’s the headroom like in a fb? I’ve seen them in real life and the slant back is big
'Being an 18 year old and blowing the motor of their car is not a great place to be, I wouldn't recommend it to *anyone*.'
:')
I'm there right now. It sucks
"Build your dream car because life is too short not to drive it"
In that case then, I'm gonna building a diesel powered FB RX-7 and I don't care what the RX-7 fanboys have to say
I drive a black 83 rx7 and I absolutely love it, it only has 84,000 On it, it’s my first car and I want to swap it to a 13b eventually but I was wondering how much it costed you to do the swap? Also is you have any tips for the 12a I’d appreciate it!
Collin Waech I'd say about $2500 is a safe number. And honestly, I found the 13b is better for daily driving in every way lol. I liked the 12a, but the 13b is a whole new world
Shooting Cars okay cool thanks and keep up the good videos they’re helpful
Only 84000 so it’s on its last leg
This is amazing
how much was the megasquirt nd which model? it seems like nowadays thr products r gettin extremely expenve... also was ur 13b s4 do u have the aux port engage via tha megasquirt with motorize or external vacuum engage or u just pulled the sleeve out open??
Where did you get that shirt? I want one!
Bud we are on the same road ☺️😉
I have a problem with the electric distributor and I'm not sure what to do because its brand new
Good job! What is the total cost of the completed swap? Is the performance of the s4 na better or worse than a gsl-se stock with the 13b six ports engine?
Alexandre Messier around $2500 and that includes the standalone Ecu, harness, and all the other upgrades. The S4 is slightly better than the GSL-SE stock vs stock, but has way more tuning capabilities and more parts that are easier to find, since there were so many S4 FCs and not so many GSL-SEs
what a lovely car
Have that same maroon interior on mine.. i do wish it was black..
Great video man
i just want to know which of the mega squirt ecu he's running
MS3X V3.57
So happy to see Rose up & running! Well done!
i respect yu doggy i thnk othr ppl do too. just cus ur real
Damn do I want another one. I'd let you review my conquest lmao but honestly it's so sketch i don't let other people drive it, no rear calipers lol.
Question for the community: Can you Mild Street Port a 1989 automatic convertible? If so, what are the HP gains?
if it's a rotary you can street port it. you'll get anywhere from 10hp-30hp gain depending on how crazy your port is, and with proper tuning. while it's out of the car might as well throw a 5 speed in there.
You should do a video on some touges.
Jp Sierra gouges are 1vs1 races on mountain passes, it’s illegal
Oh and also, touges aren’t places
I had a 89 gsl se with the 13b cherry bomb exhaust and couple other mods. I beat the shit out of some mustangs and a old school supra... I drove that car daily... The motor I was running wasn't even street legal in California I couldn't smog it used to get the numbers to put in the window from DMV and I would only get about 60 something miles on a tank it had to be a race build I got it from a friend that built two of them. I got rid of it pretty fast.. But I miss that car so much
remykid Not an '89 gsl-se...
Wanna swap an fd 13b-rew or a 20b into my 2010 rx8 once she finally breaks
Can you give me the dishboard i want to fit in my mazda
First time watcher. Just noo.. big webber and bridgeport 12a or 13b is what makes an early mazda.
I like my 12a more
Bridge port it of pp
That rx7 with you in it weighs as much as a completely gutted charger hellcat.
