I just found a complete 22RE Turbo motor for $100!!!! Has everything minus the airbox. Even has a spare turbo.

My 22R is rebuilt and carbed so I just want to put all the turbo EFI stuff on my rebuilt block. Plus the motor im gunna buy has a bad crank.

So what im getting at is how hard would this be? What snags should I look for? What would have to be changed?

I know exhaust will and these dont have factory intercoolers do they? I did use the search button but didnt find too much...I want direct answers! lol

All insight is appreciated.

Also should I snag the cab harness too?

Nothin?

It's is late, you'll get more people to answers your questions tomorrow. Turbo is a rare models/option, you would need everything from donor truck, including computer, it's doable, does the donor truck still have the digital cluster in it? good to get that too...Sounds like a fun project, might take a while to complete, good luck!!!!

added: I've seen 2 running turbo toy trucks and they had the digital cluster, they looked cool, didn't remember if they were SR-5 or not it was in the middle 90's, saw a wrecked truck in salvage yard with digital cluster, but had no engine just a turbo emblem, don't remember a SR-5 emblem just sugested he get it if the doner truck had it, cool item to add...Heard to many unreliable stories about them, so I personaly stay with full guage cluster...

not all turbo trucks had a digital cluster...i believe that was the sr5 option.

the block will need an oil port for oiling the turbo...among other things...but it is doable

its a wealth of information

Yeah I was thinkin that. But yeah I want to try and get everything out of it that I can.

not sure if I can help, but I just did a swap this past weekend. I swapped my 5 speed 22ret from my 1986 pickup, to a 1985 automatic 4runner (also did a 5spd swap while I was at it).

From the turbo pickup, all i took was the computer, engine and complete harness. Everything bolted up to the 4 runner and the harness was plug and play. I also took the sr5 turbo cluster from my truck and swapped it to my 4runner, again plug and play.

For your setup, I know that you will need a high pressure fuel pump and Im not too sure on how different the carb body harness is from the efi body harness.

You will definitely need all the electronics, harness, sensors, ecm, all that good stuff. I could be wrong, but I don't believe that the intakes are interchangeable, which will be a massive problem with massive modifications needed. The oil port is not a real big deal, as there is an oil pressure port on the passenger side behind the motor mount, that everybody uses on a RE block. Once you get past those problems, then you're going to run into problems with your compression. A stock turbo motor runs alot less compression and is tuned for it, a N/A motor is not going to run the way you want it to with a turbo, unless you go with a standalone unit like megasquirt. Go to www.22rtetrucks.com and spend some time reading. I have a turbo, and after all the money I've dumped into it, I wish I would've gone a different route.

He has a turbo donor motor. So if he uses the head from that compression won't be an issue.

My daily is an 86 turbo 5spd and I love it.

One hugely important thing is make sure you use a good headgasket and arp headstuds.

BoostedRNR

The head isn't the main factor in compression, the pistons are. The head will drop the compression, but not enough to run good boost.

I think you better get the whole truck, you might regret just taking some parts.

It might be better to just fix the 22RET and just swap it whole, you might just save yourself a lot of headaches.

BoostedRNR

I agree with this dude, or just put a chevy in it and avoid most headaches

Yes, I forgot about that lol. A lot of rte guys want to run the n/a heads because they are easy to find...so there's always lots of talk about the compression differences in the heads, but the pistons are indeed the primary part of that.


Personally I'd do it right or not at all. If you're going to go through all that work I'd completely rebuild the turbo motor.

No body has said anything about the piston oilers in the 22retc block.

The oil engine was designed to be used with the turbo.

If you want this done right so it works rebuild the turbo engine you will have a lot less grief in the long run.

For what it is worth I just sold a running 22retc for $ 1600.00

Seems most of these that blow need cranks.

Good Luck

I am about 99 percent positive that the rte doesn't have piston oilers. If they do, somebody please show me proof.

IMO 52/54 CC to 82/83 CC combustion chamber is a significant change in compression.

for example, on a 350 SBC if you go from a 76cc chamber to a 58cc chamber your compression ratio would go from 8.84 to 10.72.

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.
