I just got a 1990 crx euro spec. The guy before me put a d16z5 engine in it. Its a dohc non vtec. Is it possible to get a vtec head from a B series engine?

SOHC heads and blocks don't mix with DOHC heads and blocks.

There is a possible exception, but that involves engines from 87 and earlier. And actually, I only heard of one person ever doing that, so maybe he was lying. It was a DOHC D16A1 head on a D15A3 block.

He wasn't lying...its plainly documented over at Redpepper. And while it worked okay...it soooo wasn't worth the effort/expense.

You have two choices for a head when doing a mini-me swap, you can use a D16Z6 head from a 92-95 Civic Ex/Si, or a D16Y8 head from a 96-00 Civic Ex.

a Y8 head will allow you to use your stock distributor and has better combustion chamber shapes that prevent detonation.

I think you should use a Y8 if you can find one, but it's a lot easier to find a Z6. People say the Y8 will give too high compression, but I think you will be all set if you just use the regular pistons. The Y8 is nice because everything pretty much bolts up to the A6 block, and if you stay OBD0 your dizzy will bolt up too. Also, since they came off newer cars, they are generally younger.
I'm running a Y8 head, Dren and Tiersin have Z6s. There are a couple of other people on here waiting to do their swaps too, we have a good support group for when (not if haha!) it doesn't work.

Don't tear apart your other car for the head. You can find a good SOHC VTEC head for sale and keep the Civic on the road so you will have something to drive when you're working on the rex. Chances are you would have problems getting the mini-me going, and then you would have nothing to drive, or at the very least you would have a slow crappy civic that you wouldn't want to drive.

Well how about instead of doing all of this mixing and matching, just put and h22 vtec engine in? They sell them at "www.importstreetscenes.com" under "motor swaps."

An H22 is a rather involved swap, and certainly more expensive than a B16, which is practically bolt-in. Both of those options are also considerably more than just a head swap. We all have big ambitions, but sometimes we need to work within our own budget. I'm sure jfish would be into bigger and better things if he could afford it.

That said, H Motors Online is the best place to buy an engine swap. :wink:
