full boost on the stock gauge is between 10-12 psi

I'm thinking of putting some 15 x 6 junkyard wheels I have from a Nissan Maxima on the back with some 205/50R15 g-Force T/A's.

I know that sounds a bit skinny, but I'm thinking the lower weight and the smaller outside diameter will have a significant benefit.

get two spare TII rims and get slicks or drag radials

UniqueTII

TII wheels are heavy.

not enough to make a difference

Not for you, mr. 459rwhp, but for some of us, every bit makes a difference.

vosko

so get FD rims those are light

UniqueTII

Yessir. Where's the saluting smiley? Actually, my Enkei's are nice and light, so I'm all set.

may sound stupid but check for boost leaks also, this will eat alot of power. Since you don't really have a boost gauge its hard to tell, however its easy to loose alot of power that way. be thankful that you only have a couple of couplers to check, my setup has NINE couplers and i think they all leak.
