Right now I am sticking with the stock setup until I have the parts to put all on at once. I have the greddy emu with a/f cable, tophat intake, 2.5" hot-side piping, 3" cold side, 444 cc injectors, 255lph pump, Z32 maf. Would like to find me a turbo to just be able to slap in placement of the stock turbo that I can run enough boost to make 300+ rwhp. This is just for little bit of time until I can get funds together to get me a good quality bb turbo and quality manifold. Any suggestions?

I am thinking a t3/Super 60($700) will be a good choice or a t3/gt2871r .86($1200) should also be good.

WHAT MOTOR?? (I'll guess RB20 since you are have 444cc injectors)

1) Don't get stuck on BB turbo's being all that. My journal bearing turbo outspools a GT35R and makes the same kind of power. O yeah, and I got it used for $200. They are $500 new. Holset HX40 (on an RB25)

2) Don't waste your time on the intake unless you are chasing more than 500rwhp. *edit-I see you already have it

3)You aren't going to find a cheap bolt up turbo for an RB. You'll need to get some stuff made (downpipe, intake piping, etc.)

Save you money for the turbo you want in the end. Turbo's are cheap in comparison to supporting mods, and it looks like you already did most of the expensive stuff.

I'd ditch the Greddy EMU,And ditch the tophat mani cause they are not good parts.

Also for 300whp You may be able to achieve it with a rb25 turbo.However if yiu are gonna change down the road enjoy what you have now and get something else later on

Thanks guys. I can't believe I forgot one of the most importnant details in you all helping me. The motor is the RB20DET. All the piping and exhaust is going to be done by me. I weld for a living.

I'm not going to ditch the emu nor the intake. I am not looking to make a rediculous amount of power. Both those items will certainly help me acheive my 300+ goal for now. I was just looking for an intake that put the cold side intercooler piping away from the turbo.

I will check into those turbos and see how I will like them. Thanks for the assistance.

T3/T04E 50 Trim Turbo should be good for your need and some. a preowned one should go for about $400 if you're on a budget.

O yeah, 2x on tying one end of a rope to that e-garbage, and the other end to a rock, and chuck that piece of **** off a bridge. You'll save money trash canning it and buying something else over trying to make it work, assuming it doesn't blow up your motor in the process.
