Greaser?(This is about your sig) why in the world do you think that a KA24DE would be as good or better than an SR20VE? hands down the SR20VE will blow it away as for turbo motors, KA24's do aight ill give them that........sorry for the off topic, but the 2657 sound s about right for a fastback, And i love my 89 180Sx.........(Too bad my cousin wont let me have it back...)
