What I have:
(1) DOA CRX DX with blown 1.5l motor, 196k miles. No idea what's wrong with it. (Was getting some white smoking prior to an abrupt power loss and death over a year ago.) Tried a rudimentary compression test: got 65-75 across all cylinders.
(1) Full Z6 long block, now torn down and cleaned, head, intake and block are separated. Engine was pulled from a '97 EX wrecked with 92k miles
(1) Stock P28
(0) Ability to do a swap myself (no time, no experience, no garage, and its gettin damn cold outside)
(1) Local import shop here willing to do the swap

What I want: my car running again. I really don't care if its a mini-me or the full Z6 swap.

My choices:
A) have the shop leakdown the 1.5 prior to pulling to see if the rings and whatnot are toast. If not, I could save some bucks to do a mini-me, then sell the Z6 block. This gets it back on the road faster, but could lead to more problems with the 1.5 pushing more HP than before, and the block is still questionable.

B) Just swap the Z6 in and trash/trade/give away the questionable 1.5 (though a mini-me would be a tiny bit more fun). More expensive (labor costs) in the long run, and would take longer as well. :?:

Are you sure the Z6 came out of a 97? The Z6 is a 92-95 engine. A 97 Ex should have a Y8.

I vote for option B. :)
Def a Z6, I never saw the car, so I could be wrong about the year (I've had it about 8 months, kinda forgot by now). Engine was in very good shape and the teardown was by a Honda specialist/ex-shop owner who went through the internals and vouched for the amount of wear vs. advertised mileage.

I think the solution here is easy. Go get some d16a6 pistons/rods to put into the z6 block. Rebuild and install. Junk the d15.

Or PM7 pistons...

option B.
*edit* Never Mind...just found the Compression Calculator :rockon:

Stock is 9.13 compression
The PM6's are 10.43 on a stock Z6 gasket.
Using PM7's gives me 13.60...(12.49 with a Y8 gasket)

I'll do the PM6's if I can find some good ones. (Read: CHEAP!) 9.13 is cool though...this may be a turbo someday

*I can dream, can't I???*
