how much whp?
 

I've got a bolt on's only 87 T2 right now, but soon upgrading to junk yard semi truck core FMIC, airresearch 3 inch inlet .60 a/r compressor housing, 720cc secondaries, and the rtec ecu chip to run them correctly. and boost hopefully more than 10psi, i'll tune my fcon to around 11-12 afr. I'm hoping to hit atleast 250whp, think it can happen?

what are your "bolt on" that you have right now. you should have a good hp as it is

make sure and upgrade your fuel pump if you haven't yet, but if your engine is in good shape, you should have no problem hitting 250 maybe even 300 depending on the specs of the turbo.

currently i'm running 10psi with with stock fuel system besides the F-con on dial 9, TID, turbo back, tb mod, removed ac/ps/twin scroll and evened up the turbine runners

forgot to mention i'll probably go with a mkiv supra tt fuel pump.
