ones m4d rare jdm, i dont think you can put the a1's in crx. but what do i know?

Re: what's the diff?
 

the a1s go in the 1st gen rex/ 3rd gen civic.

Re: what's the diff?
 

Difference is about 20hp...and yeah, you can fit a d16a1 in a second gen crx...just have to get creative with the mounting. If i remember right they have a front engine mount instead of one off the side by the cam gears. I made a solid tube mount for the front one to bolt through the front crossmember instead, and made one for the driver's side mount as well. If you have no fabrication skills though and no welder, don't even bother.

d16a1's are for democrate ball suckers .... if your spending more than 100 bucks your not ganna make your money back

Re: what's the diff?
 

I was just wondering. cause at first glance it looked just like a zc to me. valve cover seem to be a perfect match and dizzy too. I thought the mounts were all in the same spot as other d series though. I guess I could be wrong here. trannys worth anything?

Re: what's the diff?
 

Only worth something if you find a mad rare JDM -----. :6

Re: what's the diff?
 

externally look the same


d16a1 manifold sucks balls

weaker cams

depending on years different pistons

different engine mount. Engine mount is located in the front rather than the side by the t belt. If you have ever worked or been around the 86-89 teg/84-87 civic/crx chassis you will notice this right away compared to newer 88+ honda civic.

113-118 hp d16a1
dohc zc black valve 130 hp


ya there the same
