I am driving this combo in my car right now.
I have made 2 EJ22 DOHC hybrids, 1 w/222 block & 1 w/22E block (current), both used 25D heads.
In order to mate the 25D heads & EJ22 block sucessfully, you absolutely MUST use this kind of head gasket ->http://www.ebay.com/...cd46727&vxp=mtr.
The necessity is caused by the 22E/T HGs not having the same cooling ports as the 25D heads.
Water pressure gets higher than one would think & the mismatched cooling ports will very likely cause blown gaskets.
I've been running my combo in N/A format for about 20k miles now w/compression ratio of 9.5:1 & the low end is a little lacking compared to the 22E at full initial acceleration but the midrange to redline has much more kick to it than a regular 22E.
The power produced is between a 22E & a 25D with a 25D-like power band (about 145-150ish bhp) & power falls off around 6400rpm.
The block has a little piston slap (I used a 95 22E) but it is still a very tough engine that likes being in the higher rpms (2.5k up).
My engine sees anywhere from 1.5k to 3k rpm daily & hasn't given me any issues as of yet. From it's current condition, I can get 100k miles out of this combo w/no major issues. It does have light mods (intake manifold spacer, MSD ignition coil, custom cut intake, headers) but it is proving to be quite the workhorse. I'd recommend this build for anyone looking to replace their blown 25D block & want to either boost or run it in N/A if you wanted to keep the 25D heads.
