I’m still stuck on wether to buy a pair of these or tial 3076? Most say the trials but from everything I can find, which isn’t a lot, these spoil quickly. Much better than original GT35R. Has anyone tried these on a stock motor? I know some of you have big hp builds and I will be building the engine at a later date but for now I’m thinking of slapping a pair of these on and trying it out not a drag racer or quarter mile racer just like to take the car out for fun sometimes. Already have ic’s And 60lb injectors. I would be getting new headers, Exhaust and mafless setup to go with.

i have asked a similar question before, I’m not playing around just want to know if anyone used this new gtx and even better if on stock motor?

Merry christmas all

 

no one used the gtx? I know most recommend 3076 as stock engine will be within this turbos range but I’m of the opinion that the bigger turbo will flow better and create less heat/stress at similar power levels!

 

They are a huge turbos for a 3.6, especially stock. Will be horrible on a stock motor and spool so late you won't even like to drive it. 3076 or efr7163 is a much better choice. You can do a gtx3076 gen 2 and make headers just like the gtx35 would be.
without a built motor and cams, the 35 is simply just way to big. Spool won't hit until around 4500-5k and with how limited you'll be with a stock rods, you won't be able to make much usable power.
you'll have 1500-2000 rpms of fun at full throttle and have to shift.

 

Just buy a set of K24 hybrids. They are cheaper and easy to sell when it comes time to build your motor.

 

I have been offered some tial 3076. Just like a turbo that pulls to redline rather than boost early and die off like my tial 28/60’s do. Feels like a super diesel

 

well your 2860 are tiny. They have a smaller turbine than a k16 and a 47/60 comp wheel. Any large hybrid k24 will have more than enough to build power all the way to redline. 3076 will too. 3582 will be horribly slow

 

Ok, I’m going to go tial 3076 with mafless setup and enjoy that until I build the motor. Then see if I need bigger Again. Thanks for the advice

 

I'm the other school of thought and don't mind laggy turbos. Rod problems only became an issue with new turbo technology that now marries low end tq with top end HP. It used to be a trade off of either one. I don't think it's accurate to say these are HUGE turbos cause they're not. Yes they are bigger than a 30 . I would entertain them cause the lag will actual keep the rods safe versus damaging them. These would make good power upstairs but again you might not want something real laggy. With cams it would wake up as well. 3.6 liter isn''t terribly small to spool something like a 35r but the window of usable power upstairs isn't too great as these cars (stock) don't turn very high rpm. I'd try em. They'd be easy to flip if not wanted.

EDIT: One thing I overlook is it's (2) turbos being turned. One single 35r on this car would be awesome. Two may be a little more difficult for usability, but I'd still try it.

 

Cool you sound like my brother

He think I should be doing a pair of gt42’s or 45’s

 

I have been told you can let the stock motor rev to 7500! Not sure if that’s accurate? Guess it’s one for the tuner which will likely be sambott as he seems highly recommended and reviews of the Cobb interface are good aswell

 

Interesting, I never heard of one of those before, and only briefly looked at it, but IMO it's a little silly/gimicky. Why would I want another flapper inside the housing? I had an issue many years ago running a manifold that was from an AT which was slightly offset thus slightly blocking the turbo and car ran like ****. It would be similar to this I think. Curious to those who have run these things. Theory is always better.

 

stock cams do make power to that rpm, but do it at your own risk with stock valvetrain components... need the re-designed 997 lifters at a minimum.

 

Yeah I see it's got some positive feedback. Have to run divided housing though. Interesting, I wonder how it deals with the heat over time.

 

This thread has become very interesting. Learning new stuff all the time now. Great info gents

 

I will be interested in the quick spool valve setup, we tried it 6 years ago but there was not enough room. I think its might be possible. We had GTX3582R Gen 1's on my brothers 996 Turbo car and made great power, spool didn't bother us as long as you were in the right gear. If you are planning on keeping stock motor I wouldn't waste my time with anything larger the GT30's, They are good to 1100-1200whp on full kill. As for turbos I love my 6466's the car made 1300Whp on e85, and will make 15XXWhp on racegas when I choose to push it harder.
