I approximated the piston specs from here: http://www.d-series.org/forums/engine-b ... -info.html
got the other block info from here: http://en.wikipedia.org/wiki/Honda_D_engine#D14A4

entered everything n the Zeal calculator and:



actual compression might vary by a few points depending on the dish volume of your pistons. I couldnt find authoritative numbers for that anywhere so I guessed 5 cc. also the head gasket thickness will affect your compression numbers. I strongly recommend going to that webpage and playing with that calculator. its fun.

you should be able to swap heads straight away without any issues.

Couldn't find this?

Stupid google not returning my site since a year or something...?
[edit: entering "piston dish d14a3" gives me as 3rd hit! And 4th hit is correct page]

So dish is -5.4 (you were really at the money!)

And Zeal forgets compression of the gasket which should be 0.028 when installed.

But you were close, I got CR 8.50

I can be lazy sometimes. LOL!
