Default T3/T4 Wastegate

What size wastegate should I get for my T3/T4 turbo upgrade? Also what size injectors do most people go with for this turbo? One last Question what length oil feed and return lines should I go with?

TIAL 38mm. the injectors depend on the tune. either 440 or 630.

Brian, there's no way he can run a t3/t4 with 440cc injectors, what are you smo-- oh wait, I know the answer already


haha just kidding. but really, 440cc is too small; the boost would have to be minimal, and I don't think the tuning options available (Chris Tapp?) favor small boost like that.

MasterY, what trim are you getting? if you're not going above ~22psi, look to the 57trim, because it'll add 15-20 more whp in the 18-20psi range even at 2-3psi less boost.

well he is tip. i figured he wouldn't be running that much boost anyways. you can run 18psi out of a 50 or 57 trim with 440's no prob.


but yeah im gettin 630 for my setup, the ctapp tune is siemens 630 and ford lightning maf

ITs 630cc not 660ccs's. The 630 tune is better than the 440 tune. Basically wouldnt run anything on the 440cc file unless its like a gt28r and maxing out around 300whp. ALso, all you need is a 3" maf housing from a vr6 or 225TT.

I'm looking at getting the 50 trim with the .48 A/R. Will this turbo fit on a test pipe with the 3 bolt flange or do you need a different flange?

you will have to modify more than just the flange. The turbo will be in a new location also

well since your going from a bottom mount to a side mount, you can put 2 + 2 together

the manifold you use will determine the new location. its not gona be drastic or anythin but with the k03 testpipes you could run into clearance issues. an exhaust shop should be able to fabricate one
