18rc parts to 18rg??? Mon, 15 November 2004 02:24 Go to next message
hey guys, this may seem like a really stupid question to most of you, but i am 15 and a complete amature wen it comes to car engines.

Currently got an 18rc, has had the head shaved, port n polish, cam grinded, and has got 4.2.1 extractors and p formance muffler.
just wondering if the 4.2.1 extractors can be put on an 18rg?
and wat sorta of performance i may get from my 18rc compared to a standard 18rg?

No, the exhaust manifold is not compatible.

It's hard to say how the performance of your 18R-C will compare to an 18R-G as it depends on a lot of factors (eg the specific cam grind specs, the quality of the head porting, the carby you're using, whether it's been tuned properly) but it's unlikely to be a match for a stock 18R-G in good condition.
