I am currently running a GT35R 1.06A/R and happened to go to garretts site and noticed that there is a GT37R/GT40R now.
My question to all is I was thinking of going to the 37R and dropping my A/R to .99. Would I just be recreating what I have or will I be able to hit with more punch and spool a little sooner?
This just the begining of me looking into it. It started from bordum at work, I haven't even started comparing compressor maps yet...

Currently GT35R A/R1.06

Thinking of
1. GT37RA/R.99
2. GT40RA/R.88

Last but not least would those trim be restricting me at over 30 +PSI of boost( just used for dyno playing usually stay around 15-19psi otherwise).

Would love to hear your opinions!!!

HEY! I drive it on warm days(twice in the last week) it's been chilly lately so it has been resting. I haven't seen your's moving anywhere either CPR.

You'd be putting that turbo on for bragging rights only.. Put a smaller t-3 .82 A/R on it. (GT35) Tial.. you'll love it and it will cost you less. If you're running 16psi, you're only going to gain spool with none or almost no top end loss.

I would wait for the new Garret GTX series to come out before I changed turbos.. wait to see sort of thing.

Bruce: Do you have a link to the turbo you are talking about?

This is just a GT35 Map.

There is a GT3788R map on that website also. jut click on the turbo size.. map will pop up.. You have to scroll down a little , its under large frame turbos

You need to post what engine you are running and your setup which would help people give you good advice on which turbo would suit you best

I think that many of us would like to one day have a GT35r on out cars i have 2 gt35s here but i was waiting till i have a 3.0 to put it on and just using a k27 for the 2.5...So if i was lucky enough to have a Gt35 on a car and it was working ok there is a big list of things i would do befor going to a biger turbo , engine work super fuel system 4 coil cdi 4" exhuast big brakes heaps of suspension roll cage .
No doubt by the header pannel you car is no stoker just i would want to have a very highly developed car to see a gt35 as enadiquite

Well Rock and Dan I plan on falling farther to 107. That looooong day on the dyno will never leave me will it ?? I guess I will rely on the two of you to put that on my headpiece over my grave "114HP dyno tested"

95one, The GTX-R series when will that be out? I am not trying to drop my boost build zone I would like to leave that if I can close to where it is but I would like it to have a little more punch on boost. I will look at the maps tonight and make the decision if that will be the case or I will be just recreating what I already have. The reason for the drop in A/R is soley for the growth in turbo, I am fine with the GT35R in that sense.

gt37vgt The only thing I lack on your list of thing there in the roll cage I do not thing that will be ever placed in this car at this point.

Costas, forgive me for my forgetfulness but is your motor a 2.5L or bigger? I know Duke was/is running a GT35 on a 2.5L and I ran the Vitesse stage 5 on a 2.5L but I had the S2 crown wheel and pinion to offset the final drive ratio.
