what are the pro's and con's of installing a 22re head onto a 22rte (turbo)
short block engine.
the non-turbo head has a smaller combustion chamber, what kind of compression ratio will I end up with?

 

somebody out there has to have tried this before, all opinions are welcome!

 

what exactly do you want? yes, it'll bump up compression but you want lower compression for a turbo, and if the engine is N/A you'll still have the dished pistons so it'll have lower compression than you'd want for a non-turbo engine.

 

will the compression be to high to be able to run the stock turbo setup?

 

If i were gonna build a 22r turbo i would use an early block and head and use late model pistons to decompress it. An early 22r has mini dome pistons and hemispherical combustion chambers so the flat top pistons would be decompressing it.

 

that'd be a decent idea if you have an early engine sitting around begging to be built, as long as it's an '83 or '84 head(efi compatible)

 

i have a unique situation. My 85 runner has an 84 22re out of a celica in it so if it ever comes down to me building it, thats my plan.

 

The engine that we are working on is a 1987 4-runner turbo w/auto trans. (22rte).
The engine overheated so we pulled the head and found the headgasket to be blown and the head was warped. We have a head off of a 1985 4x4 pickup (22re) EFI that we thought about putting onto the turbo bottom end to raise the compression.
We live in south eastern Idaho so we usualy drive between 4500-8500 feet above sea level.
The compression ratio should fall somewhere between 8.25:1-8.75:1, at this elevation it doesn't hurt to run more compression on a normal engine but we weren't sure on a turbo engine. With boost pressures between 6-8 psi it should stay together, we hope!
I guess the worst thing that will happed is we will blow the head gesket again.
The turbo head is still good it just needs resurfaced.
