how the hell am i going to accomplish some really good hp without those 3 things?

 

You won't.

 

Drop a v8 in there, get around 400hp and be flamed by the entire forum?

 

i think i will just get a mad street port, and a 60 shot of nitrous oxide and beat all those little ****** cars

 

Hey, you just said without those three things and you just included two! CHEATER!

 

NO!? lol, yeah i know....but i want some serious power from my rex...if i can't do it threw little things (air filter, exhaust) get it ported and then nitrous it up

 

Good luck to your engine, it may need it! I just got my GXL home, I don't have an engine to play with yet!

 

What do you consider 'serious power'? I consider serious to be over 500 hp

 

Yeah, the only vehicle I have with 'serious' power is my truck, and that's because it can have all the power it wants and I'm too afraid to use it. Something about a big rusty chevy with 450hp just doesn't seem safe to me!

 

no turbo, Nos, or porting?
How about 36 PSI of ATI Procharged Aftercooled Supercharging. Taht count?
36 psi will make GOBS and GOBS of hp, but even more so with porting.
and extensive fuel mods would be required for that pressure.
