cheers guys...
sydney kid: that all sounds good... but i really cant be F$%#ed with having to screw around with hybrid engines (i'm guessin an rb31det is a hybrid)... as i am looking to build the factory engine... but it still sound tough
nedb: thanks for your input... much appreciated...
also, is geting about 400wkw in a GTR really as simple as they (zoom magazine) suggest? ie. upgrade exhaust, turbo's, injectors, ecu, intake......
