find a Z31?, hmmm ever try carsoup.com or autotrader.com? The guy that is saying 240's are better.....think again, the KA in japan was used as the "truck" engine, if you do ever consider a 240 find one with a CA18 in it already (its the REAL stock engine for a 240) I dont think at all the VG's are shit, I lined up next to a 240 on the strip and pwned him....I am NOT saying its faster than ALL 240's I am merely stating the VG has more potential.
Here read up a bit on the VG engine. you fall in love....
