In my opinion, a perfect sleeper would be an 89 xt6 with an 05 sti engine and 6 speed (gotta love that diff), custom a-arms to accept sti axles and running gear (bearings, hubs, brakes,etc), new rear end out of sti, the least flashy rims for an sti (to fit hubs/brakes), and last, but not least, a 60 shot wet nos system..... just to prove your point. Hmmmmm..... just guessing at its output, but wouldnt a 60 shot put the hp/trq at near 450/500? I'd love to see those hopped up deisel truck owners faces when their doors get blown off at probly the tune of 0-60 in 3.0".......
