Okay, I'll bite. are you looking for 300-hp at the front wheels or at the flywheel?

im looking at 300 hp at the front wheel just to begin,then from there move up to 450 or so. i guess i will need a turbo that can support 450-500 whp,i was looking at the post about precision but im confuse about those.i dont mind a little lag,just something where i can get full boost at least at 4,500 rpm and hold on to 8,000-8,500 rpm

 

So you want a turbo that can support 300 WHP?? Or a turbo that can support 450 WHP?? Big difference.

Most of the T3/T4 hybrids will push out 300, but no where near 450.

You'll need something like a 60-1 or a T66 for 450 WHP.

 

What? T3/T4's have been known to make up to 600WHP+ depending on trim and A/R on a a B18.

 

"T-66 for 450hp..."

WTF??

If this was not a mistake, you obviously have no idea what you are talking about...
