1987 turbo head

Does anyone know where to get a reman. or new head for a '87 22 RET 4x4. Any info will help. Is it possible to take my 22 RE and swap it out for a 22 RET? I already have an auto transmission in the truck. Thanks people!!

The turbo head has a larger combustion chamber to lower comp ratio and I believe has heavier duty valves (exhaust anyway) for the extra heat. Some people run the the non turbo head on the turbo motor which bumps the comp ratio up from 7:5:1 to somewhere around 8:5:1 which is fine with out too much boost. I'm doing that on my 87 turbo pickup. engnbldr's street/rv head has heavier duty stainless valves (larger too) and is all new parts for $448. That's what I'm going with.

The pistons have a smaller dome for the lower compression, its not a larger chamber. At the end of the day 1pt in CR is not going to make any difference.

a late model 22re piston is damn near flat how much smaller dome is there really gonna be? And the difference between a 22re and 22ret engine is NOT a 1 pt difference.

Turbo pistons are different then 22r/22re pistons though but not much.

I have said this before and I'll say it again. The turbo head also plays a major role in the engine's compression ratio. And does have a different combustion chamber size.

IIRC the turbo head is also plumbed for the oiling system for the turbo.

Now searching around here are some more specs with the KB pistons with a 56cc head (efi) = 9.7:1 with the same pistons and an 83cc head = 7.3:1.

22re compression ratio = 9.4:1 or is it 9:1 I have seen both listed.
22ret compression ratio = 7.3:1

By that research it tells me most of the compression change between the 22re and 22ret is the head combustion chamber cc change.

oil for the turbo comes from the rear of the block.

This tells me yes. http://www.toysport.com/technical%20...tech_notes.htm

The 22RTE Turbo engine was based on the later model 22RE (short block /tall head). This is a similar but entirely different block and head. The block was drilled with different oil passages to accommodate the Turbo oil requirements. The cylinder head's combustion chamber had a different shape. The piston was dished. Advertised horsepower was 145. The factory set the boost at 5.5-6 pounds, but completely stock internals survived boosts of up to 17-22 pounds, with proper fuel injection modifications. This is a testimony to the bulletproof bottom end design.
Another good source for 22ret info. http://22returbo.net/

I've been researching this for a while now. Not for my truck, but in case I ever get a hold of an old celica/supra to run SCCA hill climbs.

The rte head will fit on a 22re,but I don't know why you would do that unless you wanted to lower the compression ratio?
