Modifying My R33

[hayden49]

Hey guys,

i have a few plans for my r33 and hope to get 300rwkw out of it by the time i have finished.

I'm doing the usual supporting mods, bosch 044, bigger injectors etc etc but i have a few questions.

i plan to replace the t25 with a gt35r so rather then doing a full turbo back exhaust now, im going to just buy a 3.5" front pipe and 3.5" cat back as i see no point in buying a dump pipe to suit the t25 then buying another pipe to suit the 35r.

so my question is, once i get the bosch 044, FMIC, bigger injectors, cams and everything is it ok to turn the boost up to 12psi until i can afford the gt35r and high mount manifold? will not having a bigger dump pipe cause excess pressure on the turbo or not?

i just cant see the sense in buying some items twice so im trying to do all the supporting mods and then save to buy the gt35r, dump pipe, high mount manifold, waste gate all in one go.

once i get the 35r fitted along with the dump etc i plan to run 18psi until i can afford a forged rebuild.

does this make sense or have i got everything backwards?

cheers

if you are refering to a rb25det, the turbo is a t3

[hayden49]

Yeah the t25g is a t3 flange but the 35r is a t4 flange which is why i dont want to buy a dump pipe to suit the t25 when im going to put a 35r on it soon.

[R31Nismoid]

A t4 flange?

[hayden49]

I was under the impression that garret gt35r's use the t4 flange?

am i mistaken?

so, I hope you are looking at an ECU before anything?
