Hey guys. I have a 1990 CRX that I use as an enduro car. I used it all last season and it dominated so this year they changed the rules. NO 16 valve engines are allowed so im screwed. I have alot of $$ invested in the roll cage, etc. The car was a DPI converted to a MPI. PUT THE 8 valve head on the 16 valve engine. ONLY THING IS IT ONLY SEEMS TO go to 5000 rpms and then she bogs out. 8 valve Hf's happen red line at 5000 rpms, but I thought that was a computer controlled thing?? Only thing I can think of is maybe my dizzy went bad last year after a bad accident?? See post below for more info. Any ideas? Is 5000 rpms all i am going to get?? Thanks!
