I'm plaing to upgrade my RS2 with the GT30 og maybe the G35/40 turbo.
I'm curently using a KKK K26/27/29 turbo.
I'm going for about 550hk.
The engine got verdi rods and malhe pisions. 7A-cams portet eingine-head. Sq-MAF.

Not sure if i shuld go for the GT30 or the GT/35/40.
I want as little LAG as posible.

Anyone who knows when in can ekpekt full boost whit these turbos?

I had GT35R with A/R 0.86. Boost came at 3600 ... 4200 was full boost. My head was stock, RS2 cams, no MAF.

I would sugest GT35R. With good maping and other good hardware You could have boost lower. With GT30R imo you will only get 500hp.

What did you go for here Mr.Odd??

Gt35R with 0.63A/R would help with spool up. And 550hp is douable.
GT35R gives a LOT of tourque.

turbosize

tune the engine in small steps are very expencive :mischeif: tune the engine for 1000hp++, then are the owner who decide HOW mutch boost,and power; right

more ccm gives more boost earlyer; i will go for the garrat gt 35 for the 2,2 liter ....
I have the gt 4082 for the 2555ccm.....in my car
