swapping a 2000 jdm b18c r into a 99 civic si. Because this engine is jdm do i need a different driver side mounting bracket. I only ask because the spacing on the rubber mounts on the block seem closer together than the si bracket.

 

To answer your question, No..You would use the b18c driverside stabilizer bracket and change the rubber mount to the 99 civic si rubber mount. 19mm... Good luck with your swap!
