B18A1 into '91 CRX Si
I've ben getting a lot of conflicting reports on this swap.
Can I use my Si harness with no mods or shoud I use the Integra harness?
Should I use the Si ECU or should I buy a PR4 ECU?
I also need the valve cover bolts to the B18 (why? don't ask!).
Thanks for any help!

It was $200 for the complete engine, it was just missing the valve cover bolts. I can't use reg. bolts because I think you need bolts with special ruber grommets or something. Or maybe I'm just an idiot.

I just need to say that if you do have a si that there is no harness conversion that you need at all. Pulll your si motor with the harness still attached and then drop in the LS with the harness still attached. It will plug right in. Both are OBD0 and Both have same PLUGS.......fun swap by the way....

you can get the bolts for cheap at the dealership ... but the best thing to do would be to just just get a new valve cover gasket kit .. itll come with new bolts and gromets ... as for the wiring .. this is the deal .. you can use the si harness.. the only mods you will have to make is pretty much extend all the plugs on the bottom side of the manifold .. its only like 2 or 3 though. no biggie.
