So I was at my local pick-a-part today and saw a late 80's supra turbo. I was thinking about grabbin but I decided against it. Would it be feasible to put that on my motor if I got a header for it? And would I have to lower my compression if I do?

If its the supra ct-26 turbo, then that is the common swap on the already factory 22ret motor, so people do, do it. But that motor is built with lower compression already 149psi. the 22re has like 179, from what ive read/seen you cant do it with out lowering your compression and adding a oil line to the turbo from the motor to cool/lube it. you might be able to get a 22ret head and put it on your motor and it might lower the compression to run low boost? the factory 22ret can handle like 10psi stock w/o intercooler. Lets say you do, do the swap your ecu is going to freak out to. basicly if you want a turbo find a 22ret and ret ecu. Also if you decide to get the turbo check the turbine shaft for play or if the housing is cracked. Rebuilding a turbo can be price, im in the procces of getting my ct-20 turbo rebuild and the bills already at 850

Ouch! Well the turbo 4runners are hard to find, but I'm sure they're out there somewhere. Maybe I'll snag it and search here for a head and ecu. Why is rebuilding your turbo so pricey?

DeathSycthe02

Try lookin up 22ret on craigslist or like ebay you can stumble apoun them once and a while. They normally need rebuilt tho
The guy that owned it before me didnt take care of it, the turbo housing was cracked, the bearings were bad, the turbine had play in it, who ever rebuilt it forgot to put a part in it lol and the turbo had metal shavings in it because the motor is shot, so i gotta rebuild everything. The ct-26(supra) turbo is a better unit the the ct-20, but i wanna keep the motor factory sense the truck is factory turbo. Check out the build!

Hold on there; I'm running 12 lbs of boost on a stock 22RE - with over 180,000 miles on it lol. So never say never. The real issue will be how to run your fuel and spark management since that will make or break it.
I too was schooled in the thought that turbo engines had to be low compression but the new stuff is mostly running over 9:1 comp ratio with their turbos or blowers.

An oil line can be done with a T fitting off the pressure sensor, the return line requires some fab work, bigger injectors and some way to get control of the fuel and spark tables - but the motor can stay in the truck for the whole process =)

Rolladude1166

Well how're you running your setup?

xxxtreme22r

more importantly, for how long

Rolladude1166

That's a very good point. Also would I be able to use the stock headers?

xxxtreme22r

You can, but will need to run some portion of the exhaust to the turbo. I have seen this done before and there is a term for it, but I cannot remember what that kind of setup is called.

And with that kind of statement as a first post, most people are gonna want proof of it. As you could be someone just playing idiot games to get people to blow up their motor cus your a jeep head.

Prove to point, 9.4 compression by accident and could not get 10psi, wound up blowing headgasket.

9.4 psi by accident? What if I run it after the headers where it becomes one pipe? Could that work as well?

Goldagger

It's not my daily driver and I don't seriously off-road it any more - but it's been a year and I seriously flog the crap out of it.
I used the stock exhaust manifold and ran a pipe to the turbo out in the fender - I really can't compare that to the RET setup on the manifold since I haven't driven one but it seems to work fine.
I'm running it off a GM ECU with a Moates Ostrich emulator using Code 59. Here's a link to my build if you want proof - jump to the end for the turbo install. Nothing fancy =)

It went in like this - not in a Yota body ...

Yeah I was looking at your pictures earlier. I think before I go and make new piping I'll just run it when the exhaust becomes one pipe. Hopefully it'll clear the tranny!

Rolladude1166

Also, xxxtreme22r, if instead of modifying the head can I just get. A bigger HG and run at low boost and be ok? It seems logical to me but of course I've been wrong before lol. And I assume I'll have to run 89 octane more then likely.

Goldagger

the problem with mounting a turbo down low - like below the exhaust manifold - is the oil return. The oil just drains out of the turbo down to the engine again - that is it must go downward back into the engine - or you'll burn oil pretty bad. If the turbo mounts too low to run the return line on a good slope then you have to rig an electric pump on the line to return the oil.
I always run high test in mine to be 'safe'

WOAH 850 !? you can buy a whole new turbo with warrenty for $400, i got mind for $350, fair enough its off ebay but its still a genuin yota turbo.

xxxtreme22r

Not 9.4 psi. 9.4:1 compression ratio. Which is pretty much a stock compression ratio for a 22re. It was by accident as his piston manufacture had a type in the head's combustion chamber size. So the pistons ended up giving that compression ratio.


That's correct.

Rolladude1166 google up universal turbo kit. Specifically the STS universal turbo kit. http://ststurbo.com/universal_turbo_systems

STS is probably the most popular universal kit out there. They also address the oil drain issue like Goldagger said and include an oil pump.

The kit is not cheep though. Probably close to $3000 for a complete kit. You can pick up the turbo kit on LCE for around the same price but it's a direct bolt on. assuming running 9:1 compression as they state for their low boost system. Which is still lower than stock compression.

I also believe in order to run a turbo on these 22re's that you have to convert to MAF from the AFM setup or use a stand alone fuel/spark system.

IMO, without changing compression ratio, the cost to convert to turbo is too much considering the power gain your gonna get because you are limited to how much boost and how much timing you will be able to run.

Look at that guy I mentioned above. 10psi on 9.4:1 was only getting like 15 more horse than stock. You can run a $500 nitrous system on these things and get more than that. Of course your limited in using it only when full throttle. But $3000 cost for 15 HP is just not justifiable. Heck $500 for 15 horse is just not worth it to me.

If you're serious, why not just do a 7MGTE swap? It'll be cheaper and produce much more power in the long run...

Rolladude1166

A 7mgte swap would be awesome but I don't exactly have any fab skills and don't know anyone that does. Otherwise after hearing all this I'd probably do that.

xxxtreme22r

isn't a 7mgte practically a bolt in deal on our trucks? I don't know, never researched it too much.

Cant be any harder than turboing a non-turbo truck I would imagine.
