If you can get either engine, go with the six port. The exhaust noise is the same on both. The six port is the only one thats going to get you the horsepower, and the four port is replaced often in RX8's. Altho I believe the only problem with them is they choose to not inject enough oil in them. Never the less, they're not lasting long and the 6 ports havent given any problems at all.'
Gentlemen,
I have the opportunity to purchase a 4 port or a 6 port RX-8 engine. I thought I wanted a 4 port because I thought it would be easier to
muffel. I just heard a "rumor" that the 4 port is junk and go with the 6 port. I need 220-230
hp using the 2.85
PSRU, no
turbo. I would consider P-porting if absolutely necessary to get the HP. Obviously, I know very little about engines and want to start with the best I can get so, considering my needs which one do I want?
Thank you,
Randy
