Just spotted this. I think its all crap personally but respect to the guy if indeed its true!!
"yea word up i have a 1990 Nova which recently had an impreza 2.5 RS engine dropped into it. though this was very expensive it is now running 550Bhp (with 100 shot of Nos!) my nova can barely get traction running 30psi but still manages 0-60 in around 1-2 seconds and will tap on 160mph. This will decemate all, catch me racing Stockholm (if you can) see ya. " :roll:
