Guest Anonymous Posted November 14, 2001 Share Posted November 14, 2001 Ok...well, turbine seals are going in my stock T3 on my 84 z31, so I figure its time to upgrade. I already have a starion i/c and I would like to be in the 400+hp range and spend about $500ish. Does this sound reasonable? Anybody have any ideas on what kind of specs I should look into getting? I am sure about a t3/t4 hybrid so I can keep the stock exhaust manifold, but what kind of trim should I get on the compressor? I have heard 57 trim is good for street setups, does anyone have any feedback about this? Keep in mind my stock T3 is ONLY oil cooled, and I dont plan on adding water lines to it. I would like to get fuel upgrade in the future and run ATLEAST 20 psi. Any suggestions on specs and good/reasonable retailers?? Thanks... lataz z Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted November 14, 2001 Share Posted November 14, 2001 I always recommend folks to work with the turbo manufacturer and let them configure the specs for you. IMO, you will be hard pressed to make 400+hp with $500 and I certainly would not recommend you try to do it with a Starion I/C. For 400+hp you will need an I/C that can flow about 600CFM w/o added pressure drop. The Starion I/C was designed to support <200hp and has about a 2.75# pressure drop with nominal boost. The more boost you try to push through it, the greatest the pressure drop, the greater the heat buildup in the turbo and whatever bosst you get through it to the engine will come with a lot of heat. In addition to the turbo and I/C, you will need bigger injs, fuel pump and an adjustable FPR and some way to manage the fuel and ignition other than the stock system. That would be an SDS like Matt, 358RWHP or a Jim Wolf setup. Quote Link to comment Share on other sites More sharing options...
