Seeing if anyone has one laying around?

Also do I need to get a particular head to match by engine?
Other parts would be needed.

i have a spare h22 head and some jdm cams for it if you want that?

I also have a h22 bottom end but with no pistons - you'd need to get another set of pistons that are BBBB for this block

How much you want for the head and cams?

Trying to decide between a turbo conversion or the VTEC route. I've heard the higher revs of the H22 head could cause issues? But then again bolstering a turbo isn't exactly problem free.
Keep flittering between.

No doubt someone is going to say do both..... :twisted:

Right. I'll give it a go using my fingers instead of my gentleman's sausage to type this time :?

You'll need to get the h23 crank balanced to suit the high revs of the h22.
You'll also need a h22 water pump, intake, water pump to thermostat pipe, exhaust manifold, head, cams, rocker cover, vtec soloniod, thermostat housing. A h22 box would be a good call as well for the better/shorter ratios. Youll also need a h22 ecu.

You'd be best imo to get a complete h22, possibly car and dropping your crank and rods into thar using the existing pistons in the h22. Due to the hike in compression your probably best getting a map as well.

Due to the upping in compression you have a couple of options between pistons, ukdm, jdm or if your very brave type s. The lattee option is a bit risky and requires rod modifications.

My next motor will be a bit of a bull jobby build using a h23 crank so crack in so I can see how you get on :P

a complete engine would be better, but if you want my bits as its incomplete then you can have the block, head and cams for £100

This is a good deal. May have to pm you

If I got this all done. And done well, what kind if gains in power would I expect to see?
