Hey Goofynick : your motor is not Race Built. Sorry. Take a look into the factory oiling system of the RB's and you'll realize a few things that aren't quite "Race Built".


Your car is a factory production turbo inline six, that was found in all lower model of skyline, some Z31, and many other FOUR DOOR SEDANS from japan. It is a far cry from the RB26 that has a completely differnet cylinder head, intake manifold and ports. Not to mention your stock RB crank isnt' even dual counterweighted. You've got a long way to go to make that motor withstand real "Racing", but for tooling around on backroads, it is plenty.

But hey, what do I know about anything.
