Hey guys,
I have a 2000 GT 5sp. Im trying to decide whether to buy a new/reman STOCK motor with stock heads...OR....get a bare block and have forged internals installed. Id like to throw a procharger on it. Ive heard guys saying "forge your s***" or you'll blow your motor. Please give me all the advice you can. What are the pros & cons to putting a complete procharger kit on a stock motor?? will I blow the motor?? Or could I get a block from pick n pull, gut it, and have forged internals put in. HELP!!!.....by the way if I dont forge it and remain stock then Ill only do MAF sensor, shorty headers, throttle body, UD pulleys, CAI, 3:73 gears, and stage 1 cams.

General consensus is the stock internals will hold 400rwhp no problem. I've seen a few around here and elsewhere pushing a little more, like 410-420 on stock bottom end. But for planning purposes if you intend on more than that then you need forged rods and pistons; I'm not sure what the stock cast iron crank can hold but probably somewhere in the neighborhood of 500-600 rw. Biggest problem with the stock cast crank is balancing, it is generally not adviseable to spin faster than 6500 rpm. Forged Cobra crank will fix that, should you need to rev higher.

Figure a pretty average centri setup at around 8-10psi, with heat exchanger and supporting fuel mods and of course a quality tune will get you to that 400rw mark.
