Hey guys im from the 7th gen side of this site, and recently noticed the d16 engines are pretty bad a$$. now what im wondering, is if anybody has ever attempted to put a d16 dohc cylinder head on a d16 sohc. Ive heard this is pretty crazy, and everybody says that it cant be done, but only by word of mouth.
I want proof its not going to work if you say so. not just "I heard this" "I heard that" thats b.s.

How sweet would dohc vtec be on a civic?

It's not.

Why?
You would be able to use one, maybe two of the head studs,
the combustion chambers won't line up,
the oil and water passages won't line up,
I could go on..

If it's physically possible to do to a Honda engine, it's been done and spread across the internet.

yeah you got a really good point with the last one mindbomber. but what about sohc d16 head on d17 block? I know a lot of people ask, and those 2 guys did it but i dont think they ever explained how. heard it would be pretty complicated but personally I think it would be worth it

Speedfoose, formally of this site, is/was working on it. I know he had a thread going on d-series for awhile with lots of pictures describing the process, but it wasn't something 99.99% of us could handle at home and it would cost thousands to have a shop do the modifications. There's quite a bit of tig welding involved iirc..

So really, it's only worth it if you have a tig already and pretty decently equipped shop..
