I'm great at honda rebuilds You should pay me

To do it all right, a rebuild will run you $350 ish for rings, bearings, and all the seals and gaskets. Thats if you buy everything from majestic honda and do it yourself.

If you need a new clutch throw in $150 or so for a new OEM PP & clutch disk, and maybe $15 to resurface the flywheel.

It's not a bad idea, if you are staying D-series, to get other OEM pistons (PM6 or PM7) to bump compression, a cam, and with a flywheel. Another $400 and you're motor will be nice and fresh with very respectable gas mileage.

And the prices just go up from there. I'm sure you can imagine. GL with it...

*EDIT* Even if you swap the 88 LS motor, a rebuild isn't a bad idea. And you can swap in B18C/B16A pistons in that too... prices are pretty much the same....
