Has anyone had any experience with these turbos. I have a .82 and a 1.06 housing and I can't decide what to use. I have a 4g63 with a standard stroke. People with gt35 let me know your experience as well
Thanks

My experience.

Gt35r
.82: made 360kw on 24psi. Ran 10.9@135mph. Spooled well and was street drivable. not as good as a gt30r pn the street though but definitely made more top end.

1.06: never really got to push it. Spool was heaps later. No more "pshhhh" at idle and low rpm. Spool sound reduced. That was a far as i got. Sold the setup to Jack of all. He can tell you how it is. Should have made 400+ with the housing change i reckon.
 
Definitely use the 0.82 with the 2 litre. When I had my GT3082 and 0.82 rear it was good to cruise around in off boost but most of the fun came after 4500rpm. But if I put a 1.06 on it, Id expect itl would be similar to one of my friends 2L GSR running 1.06 on a GT35R and didnt really get busy til close to 5000rpm. But when it got there it snapped you back. Pretty useless powerband if youre shifting gear at 7500rpm.
 
Anyone else got any experience with the 1.06. I'm leaning towards going the big housing and revving it to 8500.evo-oox can u start building me another box:)

Remember Baz is running a 2.3L. So the power curve is shifted ~ 500rpm to the left compared to a 2L.
Most info i've read about gt35's in a .82 housing on a 2L says they make full bost ~30psi at 5000.

Where those power numbers on 98 pump fuel or E85 baz?I tried finding your thread with all the graphs but cant find it.
When did u strip 3rd on the dyno, wasnt that at around 330wkw? What was it stock VR4 box or running evo3 gears on 3rd and 4th through it?

Sorry for the hijack haha i was just tryin to find the threads you had on you setup with the gt35 recently

Hurry up and get your car on the road
 
That was with bp98. I've never run e85 before. I hope too soon though!

Gearbox was a vr4 rs 3.9 box. Diaqueen oil.
4th gear was the one that stripped.

That was with the.82 housing.
Dyno mode was shootout 44.

It stripped coming onto boost, lower in the rev range when the engine was starting to load up.

lol... honestly man the 0.82 rear on the 2 litre will be better for 4500-8500rpm than the 1.06 rear would be.
