I currently have a '89 Civic St. HB that I race with SCCA and NASA and am thinking of doing the MPFI swap and was curious if anyone with the swap has put their car on the dyno after the swap and what kind of numbers they might be getting. More importantly, I'll have all of the MPFI stuff in the head, including the Si camshaft, so the only difference will be the D15 bottom end versus the D16 bottom end. I know that the D15 does have a higher compressoin ratio in stock form, 9.2 versus a 9.1 CR on the D16.

Any and all help is greatly appreciated.

Regards,

Sam

 

I always figured the best idea would be to compare it to the D15B7 in native form, beyond the extra ponies provided by the cam. Not the most informative but it gives you a ballpark.
