I have been doing some searching and not sure I know what is what.

I have an 87 EFI 2.4L, 5 speed and want to install a Toyota turbo.
I loved my 87 Toyota turbo when I had a new one back in 87-89 and loved how it ran.

So what I think I need to find is an engine, transmission (R151), wires?
Because I am not sure of what will work with what, most seem to swap to some other engine or from a turbo back to a 22re. But I did find this post.

So I don't think I need the ECU?, it looks like there are some wires that need to be switched if I want to use my original ECU?
What if I get an engine, transmission, etc and it is an auto transmission, will the harness still work? Or will my transmission bolt up to the block?

Thank for any help

guess I should of posted this in the swap area

Honestly, you're probably better off buying a 22rte and ECU and swapping it in then selling your 22re.

It's not easy to turbo non-turbo cars. I have done 2 in my life and they NEVER go as expected and are prone to failure.

Just my .02 as someone who has experience with turbos.

Agree, I am looking for a 22rte to replace the 22re. So I should also get the ECU also? Will an auto ECU work?

i vote a full 22rte and ecu like swimmer said. find one out of a truck and swap it right over and go then again you could skip and go with a 7mgte out of a 87 to 92 supra hehehehehe there not terribly expensive and the only thing you need to do to make em super reliable is arp head studs, new HG, torque over spec a tad. then without any mods you will have 230hp and tons of potential and ofcoarse if you had tons of money you could go 2jz... but thats also allot of power on you rear end and needs a custom bell housing. anyways just thoughts for yah.

good luck dude!

I ran a 22RE on my RTE ECU for awhile. it ran pretty well. But I would not go the other way. The MAF and injectors are different for the turbo, and the ECU is calibrated for that.

if you do try it, get a wideband oxygen sensor and gauge, and keep a very close eye on your AFRs. if you start to run lean.....bail.


also, transmission bellhousings are the same. I bolted the RE up to the auto trans in my 4runner like it was meant to be there.



I happen to know someone who's got a 22RTE ECU that needs a home. pm me if you're interested.

I think this is the problem i found with my truck. I just bought an 87 toyota 4runner, was told it was a 22rtec without a turbo, when I went to look at the truck, it did not have the "turbo efi" intake, just the "efi". plus the exhaust manifold isnt for turbo. I think the previous owner had a turbo failure and instead of doin it right, they just patched it up to run and thats it. Gotta go to the scrap yard and see what i find for turbo intake, exhaust and maybe even a turbo....

uhm...

RTE injectors are bigger... Isn't there something about a lean condition not working with a Turbo?

And the distributor and possibly the TPS and AFM are different too...

As far as the RTE block and head... The head is the SAME ex larger chambers. And the block is THE SAME ex for a water and oil bung drilled out for the POS CT20 and lower c/r pistons.

RTE's are 7.5:1 and yes I have talked to moron that took his Turbo off and "it's running fine"

... I don't see a real high MPG motor there though...

uhhh.... The RTE's main problem is with electrical's. The maps and AFM arent real "forced induction" friendly and the old EFI batch fire stuff doesn't take too kindly to modding either...

uhh... As a Toyota enthusiast, I'd only recommend an RTE to a guy that doesn't expect modern power out of 2.4 liters. And likes to wrench a lot and is fine with it.

RTE's really aren't anything special...

Now an RE, that's a WHOLE nother story.



I need to head for bed. Any other Q's just ask.

wow, lots of info there there man, thanks. and without a turbo, id think you would experience a much too rich problem as the ecm would be dumping in fuel to accomodate for the extra oxygen that the turbo should be putting in the cylinders...mind you, it should have a MAF and that should cut back on fueling...or supposed to anyways....and as far as putting a turbo back on, i dont really care about getting modern day power from it, i just want more than i got...i really dont think that this truck will spin tires in the mud, and all i have is 30's on there right now...all i care is that it slings some mud in first gear.

well my 22re is stock internally, just has a pacesetter header, highflow cat, a glasspack cherrybomb, and a drop in k@n air filter and it moves way better than stock. these engines aren't that great turboed anyways, i dont even see the point of going back to the turbo? its wasn't very good and only was produced for like 2 years?? if you where set on keeping it a 22r then i would just build it N/A, throw a cam in it, header, intake exc...

87 'runner boosted

thats sounds better (and cheaper) to me anyways....so I should just get a 22re head or do pistons have to be changed for the higher compression ratio? I heard above that the 22ret head had larger chambers which would give the lower compression for the turbo.

Like I said in the first post, I owned an original 87 reg cab 4x4 turbo, had the truck for about 3 years, about 55,000 miles and it ran GREAT, one repair, the radio. I even pulled a 22foot boat with it around New Mexico. In the mountains, without the boat, the truck would pull most hills without a problem. Had a 13gal aux gas tank above the spare tire, which would give me a range of close to 700 miles on the highway.

so from the information I have read. I need the Engine, ECU and wiring, but I can use my transmission if needed.

91_TOYOTA_4x4

im not 100% sure but i think the pistons are different? not sure about the head but tried4x2signN knows his stuff more than me lol. just pickup up a 22re long block and plop it in

tried4x2signN

Yes, both the pistons and combustion chambers are different.

Installing a Stock Yota Turbo to a 22RE



RTE head. Though the chambers are hard to see.

tried4x2signN

If I was gonna put a RTE together, and wanted to add some pep. I'd either use RTE pistons with an RE head, or an RTE head with RE pistons...

And it'd be the latter... (B/c the head should flow better)

Oh, and without a doubt I'd get rid of the CT20.
