Whats needed for 300 rwhp in a 96-98 gt
94-98 is definitly my favorite body style but the low horsepower (225) has gotta go,,what would be the key parts to get around 300 rwhp without boost... all help would be appreciated.....
please give all info you can
part / cost / hp gain
how much hp are you guys seeing from intakes and exhaust alone?

In a word? Alot.
Think a PI headswap with worked heads, aftermarket camshafts, the stock PI intake, a T/B, inlet tube, MAF, K&N, LT headers, midpipe, catback, u/d pulleys, and a custom tune.
Just off the top of my head:
Worked PI heads: 1300
Aftermarket cams: 600
Valvesprings: 200
Various gaskets etc for headswap: ?
PI intake : 300~
LT headers 650~
Midpipe: 200-450 depending on brand and if its got cats or not
Catback: 400-600
Aftermarket tune with handheld or chip: 300-600
Intake boltons: 600-800 or so?
An easy 5 grand there, and thats assuming you do all the work yourself. Like I said, alot. its a long road to 300 WHP when your starting off with a NPI setup.
You MIGHT get away with just a set of stock PI heads and then some stage 2 cams, I have heard of a car making around 295 with full boltons and stage 2s (with a great tune) but I am not sure that it wasn't on a fairly friendly dyno.

They just did a feature in MM&FF about the same thing,just without swaping to P.I heads.Needless to say it took a massive effort.N.P.I cars dyno at about 180-185rwhp stock,there's no tellling how much money it cost them to get to 300rwhp.The head/intake swap is almost mandatory.The cheapest way would deffinatly be nitrous+some bolt ons.

my .02 cents. its just not worth it our years to go NA, too much work for small gain, and once you do a PI head swap you cant run boost cuz of compression, best bet is to get a low miles PI engine and throwing a S/C on there

I also think the guy that was on here before proves the point that its not worth it to put a blower on a NPI car anyway. I wouldn't expect more than 300 WHP even with full boltons on a stock cams/intake/heads NPI and 10 PSI or less.
