If you want to 'build' a SOHC Honda engine, the D16Z6 is THE one to use. It's the best SOHC engine Honda ever made. They can be built to over 250-HP NA...

A Z6 block with a Y8 head is best combination. Why? A Y8 head has a slightly smaller combustion chamber volume - and I mean slight. It will give you .5:1 [dot-5] more compression. Y8 blocks, on the other hand, are prone to main/rod bearing failure. Why? I don't know, but it's common knowledge. So, the hot setup is a Z6 block with a Y8 head, or just forget the Y8 head and the .5 higher compression ratio.

Then there's the OBD1 vs OBD2 situation. The advantage should be obvious to anyone except a newbie; so, no explanation necessary. Also, with a Z6 engine you don't have to deal with a crank fluctuation sensor, knock sensor, dual heated filament broadband oxygen sensors and all that happy horsesh!t.

I would guess that there are more bolt-ons and internal parts available for Z6's than any other SOHC Honda engine, but I don't feel like playing Perry Mason, so don't bother asking.

To round out the package, go with a chipped P28 ECU using the stock harness...

i wouldnt say going to a y8 head is the best. the z6 head flows better at higher rpms, while the y8 does better at lower rpms. the y8 does have the better cumbustion chamber, but alot of places can weld up the z6 for like $150 so that its just as good.

so i'd say z6 w/ filled in combustion chambers is the best bet.
