Aren't these gt35/40 guys hitting 15psi by 3500 rpms? Just like jspecracer said, expect about a 500rpm difference.

That sounds like what I want.

Any Garrett dealer or distributor can get a GT35R. It's made directly by Garrett, it's not a shop constructed hybrid.



The smaller housing and ball bearing do help the spool, but the GT series impellers are also redesigned aerodynamically for better performance.

I meant cheaper as in rebuilding is yourself. rebuild kit cost $100~ to rebuild a Garrett standard shaft turbo. But I was under the assumption that rebuilds of a ball bearing turbo were virtually non-existent since they cost as much as a new turbo. Am I correct?

I don't know, and I'm not in a big hurry to find out. It's not $100, that's for sure! https://www.nopistons.com/forums/pub...#>/biggrin.png

for a non-ball bearing turbo it is. https://www.nopistons.com/forums/pub...IR#>/boink.gif

Ok, i've never been in a car with a T04R, but i would expect it to be around the same as my T-78. My T-78 has a GT79 wheel so it reaches full boost about 800-1000rpm earlier.. so i see boost at about 3800rpm.



My friend has a GT35/40, it generates boost around 3000rpm and reaches full boost at about 3600rpm. Its more gradual.. The T78 on the other hand is like someone kicks the back of the car.. very violent, but predictable if you know your car and the sounds/tach what not..



If you are planning on doing a lot of street driving, autocross, track events.. but not concentrating on drag.. get the GT35/40 Its a good all around turbo, but won't make the highend power that the t04r or t78 will. They start to fall off up top.. They will still make good power.. probably up to the 500-550hp range if i'm not mistaken.



As for rebuild cost i don't know...



Here is a picture of my friend's GT35/40 setup.. its when he was doing his intercooler...

Here is my t78 setup.. i'm sure its a lot like a t04r...

Thanks Pete.

ok.. here's a close up of my T04-R.. I get boost around 4000.. Its not quite a kick in the ass like what twinturborx7pete said.. but its a damn good push. https://www.nopistons.com/forums/pub...#>/biggrin.png
