Ok I did forget about the returnless fuel system so I would prob go with one of the intake pumps. Does anyone know of a good set of mild cams for that set up? also can you pulley the saleen supercharger? I would be happy with 320 for now til I had time to tear down the engine and build my 5.0 stroker. I was also thinking of the lightning mass air for the job, I have worked with one of them on my turbo'd 95 and worked good. The 4v terminator would be bad ass but the 02 has a lot of sentimental value from my father. Here is a picture of the set up.
Honestly, don't buy that. Buy a used vortech kit on ebay for 2k.You can get non intercooled and still get 350+hp easily with your engine. You can easily get to 380 safely. Or if your prefer the roots type, buy the tork tech kit and install it. That kit is 500hp capable as well.
If not that then just take that 1000 you plan on spending on the supercharger and buy heads and cams. Again your better off since you'd be saving money overall. If you buy that unit, upgrade to a 5.0 stroker do heads and cams you still wont be over 400hp. Trust me I know. I did that too! I sold my saleen unit for the vortech because I couldnt get over 380 with that crap. I have a 5.1L stroker with comp cams, heads and an intercooled vortech pushing 14psi.
Second, is that all your getting from him? There is a ton of parts needed to make that kit complete, here are a few that I can think of from my kit. Intercooler, Intercooler hoses, Coolant tank, water pump, Fans on intercooler, CCRM modual, alternator relocation kit, Inlet tube, and a new metal tube from the water pump to the rear of the engine. I forget the name of that tube, but without it the supercharger will not fit on the engine that is a 100% must have. Without it you'll be mad since your engine is torn apart and you cant drive it without that piece. Any missing part will cost an arm and leg at the steelership.
Here are a few bad things about that kit. 1) the intercooler is terrible it doesnt cool all the air some hot 200degree air reaches the engine. This is 1 main reason the supercharger sucks! running air intake temps of over 150degrees all the time is bad on the engine, plus you loose timing and loose power! 2) I seemed to loose gas mileage with that unit, probably the bad air temps plus extra weight. 3) You will also get belt slip switching pulleys, not really gaining power.
If this was a roush kit! I'd say 100% do it. Roush makes top quality products and there kit is worth every penny. Roush owners have reached 400rwhp with that charger before, its not easy but can be done. The saleen barley gets passed 370 with thousands tossed into porting, fixing intercooler, fixing lower intake manifold and so on.
Either way good luck with your project, but to be totally honest if your rebuilding your engine skip the supercharger. Buy a short block, heads and cams and run that till you can afford a supercharger. The saleen is way to much hassle why do you think its 1 so cheap 2 pretty easy to find used. Roush chargers and never used unless that person rebuilt there engine and wanted more power.
