We take a closer look at the G-Series range of turbos, specifically the G30 and G35 range, and compare them to the GTX range in the same frame size. We compare wheel sizes, design and more. For more info: www.garrettmotion.com/ - Auta a dopravní prostředky
This is such an amazing comparison that I have been looking for forever!! Thanks for making this video. I'll definitely be sharing this on the forums!
You’ve been pumping out some great content!
Another great and informative video Andrew! Thanks for putting the knowledge out there for us all.
Andrew, these videos are great. Well done on the stream of content that you're pumping out lately.
Wow, Andrew is delivering awesome and informative content back to back ... This channel should have 3mil subscribers by now.
I really love the spreadsheet/ compressor map comparison, feels very much like a japanese Option video where they really like do dig down in to the details
Thank you for making such a detailed vid of the Turbos, I am such a noob and have no idea which Garrett Turbo is which. Now I way better picture now. Love your content guys!
Keep it up!
Great video, just what i was looking for. Thanks!
Awesome rundown on the comparisons!
Great video Andrew on explaining it in simple but very technical terms
Really helpful video.Thanks a lot!
Awesome content as usual
That was a great comparison, good work.
Top explanation thank you mate !
Very educative. Thank you.
Excellent presentation. I'm using gtx3582r gen 2 with a 84RS turbine now. Will go with G35-900 next time.
Amazing as usual 🔥
Best informational video for these Garrets
Awesome stuff Andrew.
Awesome video guys answered so many questions for me. Just curious as to how this would compare to precision’s 6466 or something similar in the 900hp range..?
So tempted to install the G30-770 on my STI 😍😍😍😍
Great vid... Looking at the g30-770 for my STI
Amazing explaining
Great video as always Hawko, very informative. I've got a twin -5 setup kissing 500 wheel HP at 20psi. The prospect of the G30-770 on a street 32 GTR making 600hp, coming on sooner with so much meat in the mid-range.... oh I'm drooling.
Would the g30 770 outshine the gtx 385rs in your opinion in a 1m I may track and street?
Get a hypergear does the exact same job and doesn’t cost 3k
thank you for this video
Interesting to see that the G35-900 is practically a hybrid of the 3582 Gen 1 & 3576 looking at those inducer/exducer numbers. 👍 Good thing about these turbos is it pushes the price of the lower series down. GTs & GTXs have never been so cheap. 😎
Thanks Very Informative
Awesome video
waiting for results on the G35-900, looks promising.
Looks very promising. Hence we chose it for Project No Secrets
Another informative episode. I look forward to all your technical, parts & projects videos and can't wait for the next... I expect a G35-900 will be finding it's way onto your Project Supercar Killer or maybe a slightly smaller G-series onto Project No Secrets?! 🤔
Keep up the good work guys & girls 👍🏻😁
We already tested the 1050 on Supercar Killer and we announce what we’re doing to it in the video we release just before this.
Andrew I got the hint that project no secrets is getting a G35-900.. lol
You booting it though that smoke on track reminded me of days if thunder 🤣🤣
what a great video
Would love a g35-900 supercore as a replacement for a gen 1 gtx 3576 on my barra. Looking at some of the US sites theres a supercore for the 1050 but no mention of the 900.
I hope they come out with a T2 style exhaust so I can straight bolt up a G25-550 to my CA18DET in my 180SX I know many don't like the CA but it's the original engine and been going strong since for 20yrs now. I'd just need to upgrade my GTR 444cc Injectors and a aftermarket ecu and sure can pull some good numbers everything else is done many moons ago.
Top Video mate ,geez i wonder what cars getting the G900 lol , sssh its a SECRET LOL.....
Looking at stepping up to a G SERIES SOON
I have the g30-900. Hard to find any info on it :/
Have you tested borgwarner turbos? It would be cool if you could test a efr8474!
what would be better a twin scroll gen2 or a G series??
Hey what is the name of the song at the beginning of this
Anyone making a twin scroll v-band exhaust housing for the g-series yet?
I like how Garrett just assumed I don't need or want twin scroll just because this turbo is better than their last one.
Surprisingly, there's more to twin scroll than better response.
i believe they offer a 1.06 T4 Divided option now. i have a built 2jz. i’m chasing 470whp-600whp. i’m wondering if i should go G30-900 divided or g35-900 divided. i’m leaning toward G30 but i feel it will be a handful.
@motive Video - @ 7:26 what is that black circular thing exiting the turbo by the oil feel lines? is that a pre filter? thanks again!
Which one might you chose for an LS 7l motor in a twin turbo config? The compressor maps show both (same flow) being right in the sweet spot of an engine limited to 12psi. This using the Borg Warner turbo selection program, which is far better than Garretts.
6:21 what gauges are those? I'm assuming its a Skyling GT-R 32?
GREAT video, thanks for the info. I'll go with the Holset HX40
Howd you go with the hx40

i have a GT3582R...i plan on installing it on my 2.4L, inline 4 engine with 8.8:1 compression. does anybody know how it would act? thanks
on a stock engine and looking to re-build the entire engine in the next few years, what turbo do you recommend for response but not get left behind on a roll race? usingt e85 with haltech and t4 6 boost
Hello, thank you very much for your explanation of the G30 and G35 turbos, I wanted to ask you for an advice, I have a gtr r35 engine 3.8 stage 1 ams and I am deciding which turbo I install the G30 770 or the G30 900, I use it for street races and 1 / 4 of a mile, what is your opinion? Thank you so much
Ive got an RB26 in an R34. Oil pump head gasket, head studs e85flex and fuel pumps. Id like the G45, but looks like the 35 is the go? Wanting to make 700 wheelhp, but dont want to have to much lag, would be good to have the bigger turbo for later when i get my new hermon block.
Can the G45 work?
Will you suggest what turbo to throw into my fully built n54 in my Bmw 1M. Unclear if I want a 35 or 40 and if either then which specifically would you prefer? Thanks man.
this or a efr turbine ? im looking at g25 660 vs efr 7163
amazing video as always, you are turbo jesus
why he he didn't go for a bigger a/r turbine housing beside using the 35 over the 30 ?
How do you thing the g35 would go on a Barra?
I have a G35-900 1.06 on a built 2.6 with cams + E85. Spools at 5500rpm. Can gears dialed too. Does this sound right? Having second thoughts about this option . I know this differs vs what you preach about single setups
Yaaayyy I was planning on buying the g30-770
Did you get it and why over the gtx 3856rs?
@@luciengutierrez431 hey man, going gt35 1050 now, they’re new turbo and not laggy

G35-900
@@MotiveVideo Thank you!
Hello :-) Could you please so kind and give me your opinion. I am a drifter and drive a E36 M50B30 ( 3 liter stroked ) non vanos engine. I have 282/252 degree turbo Conversion cams form the brand Cat Cams. I use GTX3076 GEN II 0,82 A/R Turbo ( 1.8-2.0 bar of boost with E70 ) and also NOS for the lower RPM. My question : If I want the change my turbo, which of these ( G30-900 or G35-900) would you prefer to me? I need of course quick spool and more power at high rpm ( linear power range from mid to high rpm ) . Thanks for your reply :-) Regards from Turkey / Istanbul :-)
Was hoping you put the gtx3576R gen2 on there as I've got it on my 1j
We used one on JET200. Awesome turbo
vvti? give us a spec list
Why can’t they just drop a twin scroll rear housing for them and be done with it.
This is one thing that's confused me, the truth lies in the middle
what would be more responsive a twinscroll gen2 or a g series?
Sure has me considering a change one day. I have a pair of Zonarotor turbos equivalent to the GTX3076 on my VQ37VHR. I can turn 8krpms and the turbo's are falling off up top. I need to dump some midrange and put it up top.
I dnt understand twins that well but on a 3.7L shouldn’t G35-900’s be overall better without loosing much response?
Hell yes, I'm wondering how well will the g35 flow and respond on a Honda b series GSR 1.8 would be very interesting.
get a g25/550/660
Great Video as always mate!
Would be awesome if there would be a comparisson between the Turbos at the same power on these different framesize Turbos while looking specificly at the IAT and EGT, because a smaller Turbo obviously has to work harder for the Same Power and what kind of different that makes?
The problem with real world back to back comparisons is that it’s just very labour intensive both for fab and tuning and filming and editing. Also hard on a car to get pushed hard.
We may end up testing 900 and 1050 back to back.
Yes it definitely is and it is also verry cost intensive too. Just seeing those to in comparison may let the results scale up or down for the larger and smaller models of these Series. This will definitely be interesting to see!
Man I love your R32! Keep up the good work 💪
For something like this to be a reality, it requires thousands if not 10's of thousands of dollars of capital including parts costs then attempting to recoup cost of parts on resale. If the people who are interested in such back to back comparisons would work together to fund something, it can happen and you'll have all the data on you.
Sometimes smaller is not exactly better as it can choke a motor up too much.
Hey Andrew do you think the g35-900 with the biggest A/R (1.21) would have similar lag to the gen 2 3582 (0.82)
Im doing an upgrade at the moment on my 33 gtr and ive got a gen 2 3582 with a 0.82 (not genuine garrett but changing to) and it's about as much lag as I'd want... no more.
Im building a 3.2L as well so I kind of want something that's ok for the 2.6 for now..but will be good for the 3.2L, I'd be looking at 550kw MAX as that's when all the other supporting gear needs changing.
Love your work, got a whole box of ignition dvd's... lol
G35-900 will be better than GTX3582 gen II. The G35-900 has same size wheels a sthe Gen I, which is smaller than GenII and more resposnive. In theory, better resposonse for same or more power. BUt no twin scroll option for G35-900 unfortunately
@@MotiveVideo I got 400kw on the 0.82 housing with a 3.5inch exhaust and standard cams. Ideally I'd like to switch to the g35-900 on the 1.2 a/r, put the higher lift pro cams i've ordered in with the supertech springs and run somewhere in the 30's for boost.
I'm also very tempted to get the 3584rs 1.01 but I'm worried it might be a smidge laggy, espcially with the 5 speed
Yeah, in for back to back
A comparison against competing precision turbos would be cool
Precision don’t give out compressor maps
Does using a t3 to vband adapter work well? (for t3 manifold to vband turbo)
As long as it doesn’t have any restriction in the adaptor it should be totally fine
For my rb2.5
Should i go g25 660 or g30 660?
Key differences?
Definyley G30. Rear housing in G25 is small. Engine needs to breathe to be efficient
Hoping you see my comment here but what’s the technical difference between a g30 0.83 turbine housing (vband) vs a g35 0.83 turbine housing? (Vband) They look close to identical
I believe the G35 turbine side is bigger. So the .83 AR on the G30 should flow less air compared to the .83 AR on the G35. As you know the dimensions on the compressor side are identical.
899 WHP (at the hubs) with an 85% power transfer efficiency (general estimate for a car with a transmission) puts you at 1057 bhp (power at the crank). I'd say your getting your moneys worth from the G35-1050!
i just want to make sure i understand this properly, if the turbo model name has the same horsepower rating they have the same compressor wheel, for example, the G25 660 has the same compressor wheel as the G30 660
How do these horsepower numbers work for rotaries? I assume 70% as compared to piston engines?
I was considering a gtx3582r gen 2, but I might hunt for a gen 1. The G series look awesome, but a little out of price range.
The 70% is normally a good rule of thumb, but garrett over rated these by a bit. The 900s comp map says it's good to 840. 840x.70= rotary reality. That being said, these turbos really like higher pressure ratios than rotories are going to see.
Gtx3582 gen 2 is a laggy mofo. I had it. I went smaller
Hey Andrew, I know you´re a Single turbo guy but would you like to see any GTR with low mount G25s (IF bolt on!?) ?
Would be cool since the most common swap is GT28.
G25s are actually quite big. even the smallest one is 550hp. Two of them is 1100hp. Two G25-660 is 1320. They actually sit in between the ratings of the singles so no real direct comparison. They’re not bolt on either and mega expensive to custom make a kit.
With the amount effort to fit twin G25 low mounts (which aren't bolt on), it'll be easier and more cost effective to just run a big single
@@MotiveVideo that 550 is just the compressor rating though not a reflection on the turbines flow capacity.
@Motive Video. On a forged RB26 2.6l with 264 cams, for a 700 crank hp objective in staying "responsive", what do you think about th G30-900 with 0.83 rear housing ? (too small housing ?) Cause you alway advice G35-900 but on a 2.6 rb26 you'll seen full boost past 5000rpm, which for me is too late.
G30 too mall for RB26. Chokes it and wont want yo rev.
G35-900 is the gun choice
.8 for petrol
1.01 for E85
Can anyone give me a size comparison of the G30-660 and G30-770 compared to the GTX2871R. I already have a nice manifold and I'd rather just change a flange and downpipe than get rid of a 1k dollar manifold and have a new one made up. The flange diagrams on Garrett's site aren't helping much
This video has been by far the most indepth with the G series turbos but im STILL stumped. i have no idea which turbo to pick.
E36, Link ECU, GT3582R currently (looking to upgrade to something more responsive with the same power)
Ive built the car for drifting but id love to get my hands in on some drag racing aswell and some highway pulls in mexico.
ive got my eyes slightly set on the G30-770 but its closer to a GT3076 sized turbo (im running a GT3582)
so then im curious about the G30-900, as its closer to a GT3582 with a smaller exducer and from everything ive gathered, keeping the inducer the same, and making the exducer smaller only increases response, so a G30-900 is like a GT3582R that spools a bit faster? (am i correct? please chime in anyone who knows!)
This what I'm wondering
@@mikereed1096I mean the gt3582 inducer on compressor side is almost the same but exducer is bigger than the G30-900. Also the turbine side of the G30-900 is a lot smaller. This turbo should spool lot quicker than a gt3582r.
@@bigjdm5460 I really hope so. I should have my car back running in a month. Waiting on some new parts to arrive then start back up.
Pardon if dumb question but, would e98 be considered race gas?
E98 is E98. 🤷♂️ but it’s not from a bowser at a gas station, so then yes, considered race gas.
@@MotiveVideo thanks guys!
Example: If you are looking for 400-500hp at 1 bar, you need to read the maps correctly: 10:09 -> Look @ 95.000 shaft rpm speed on GTX30 vs G30-660 map, you will see the "old design" GTX30 is capable of soooooo much MORE FLOW @ 95K than the new G30 660 - This need to be understood correctly instead short headliners of trim and efficiency. You need to ask yourself why the G30-660 makes barely above 0.5 bar boost @95K rpm, where as the GTX30 makes way above 1 bar boost and way beyond 40 lbs- that is crazy more quick spool-up from the older GTX30 compressor with larger compressor exducer - AND take notice - it is on the same turbine wheel diameter with 1 extra turbine blade. So add to the much quicker spooling compressor (read the map!) on the old GTX30, the added spool-up on top from 1 extra blade added on the old GTX30 turbine wheel. Ask yourself what you are after, top end power or spool-up. The G30-660 will demand for 15K more rpm on the shaft/turbine wheel to get on same 50lbs flow compared to the GTX30 (see map), how much engine rpm do you think that transfers to on a drift car if both turbos would have the 9 blades turbine wheels for 1:1 comparison :-)
No t4 twin scroll option 😔
G30-900 .83 vs G35-900 .61 is a really interrsting test cause on turbine wheels they have the same flow rate
how does the G35-900 stack up to the GTX 3584rs?
It's rated to 900. Other is rated to 1000 and larger so it makes 100 less hp and is more responsive.
@@MotiveVideo thanks, I watch the complete video, lol but as a far a Rotary's go would that change the dynamics of how the G series would stack up against the Gtx
Seriously I need to create an account to use boost adviser ? Also turbo size is one thing, but A/R can also move the power band.
hope they have smaller ones for 200-250hp
g20
I wanted to use garret on my build but I hate there names, the numbers didn’t represent anything to person who doesn’t know the brand, precision 6766 front housing 67mm rear 66mm so simple to understand, from compressed size it’s easy to work out what kinda power it will make. Ohw and if you love the HKS T51R sound precision will give you that.
Run 2 G25-550 on the track GTR Andrew.
I havent seen convincing evidence or testing the high mount modern twins will respond better. Some track cars do run high mount twins though
So if I put a g35 900 on my diahatsu Mira it will make 900hp right?
I get they are trying to rename turbos and all but doing away with trim sizes doesn't help. Wish someone would innovate a proper recommendation chart instead (ie engine cfm to rpm ratio)
Every Japanese tuner has proven every garret is better suited to trucks than high revving engines.
Just compare every trust turbo vs an identical trim sized garret. Same trim sizes, different blade angles and its night and day.
If you just want a peak number sure, save yourself the $200, but if you drive around a corner use tuner experience
62 trim turbo i believe
Adam LZ actually has a car that isnt broken?
His RBs are getting better 😁
Still behind 8 ball compared to the Borg efr
There's no proof, nobody has tested them back to back directly.
You're talking out of your ass
Struggling to get past those barras there mate. Should be walking them no prob
Huh? Starting from behind and driving around them not good enough for you?
EFR >
So called "new" turbos like these are a salesmans wet dream and thats about it
G stands for Garrett...
Andrew, surely you don't believe there's 100hp loss through the R32 GT-R drive train when in RWD only and on a HUB dyno, so no wheel & tyre mass to accelerate and "absorb" power, no tyre distortion, no rolling resistance. Just a gearbox, tail shaft, two drive shafts and hubs. If they require 100hp to rotate them they must be made of solid lead!
Garrett turbos are JDM as fuuuuuuh
