So one of my best friends has this 800+ hp Supra project that he is slowly working on. Stock internals, huge single turbonetics turbo, etc etc etc. I have my mostly stock st165. I do not want to lose to this supra. So here is whats going through my head. I want to make 800whp on race gas, and as low as 600whp on pump gas.
So far, with what I have read here on the forums, my list of upgraded parts so far are:
Gen 2 head swap for better cam selection, 3sge intake manifold, 272 cams (brand?), front mount intercooler, 3'' exhaust turbo back, t3/t4 cast manifold, turbo (size?), injectors, pistons, rods, etc etc etc...
1. What size turbo do I need to produce these numbers? Are we talking a gt30 or more along the lines of a t66? I need specifics like "If you run a GT30, you will need the exhaust A/R to be >1.05 and the compressor wheel exducer to be 86.55 mm and the inducer to be 50.00 mm 60 trim."
2. Since I have to upgrade the rods and pistons anyway, should I use a 5s block and crank? Would that bottom end spin as many rpms as the 3s can?
3. 1200cc injectors sound about right?
4. Can I get away with a piggy back or do I need to go stand alone( megasquirt is cost efffective)
