i know saab turbos. sounds like you could have burnt up your bearings. this is usually caused by a lack of oil. the lines on saabs sometimes get clogged and ruin the turbo. all you need to do to rebuild it is probably a clean oil pick and return line, gaskets, bearings, you might also want to replace the turbone if it looks pretty bad. they can be a bit spend to replace. i was curious about an aftermarket one and to get a high power kit it was around $1500 <IMG SRC="smilies/eek.gif" border="0"> <IMG SRC="smilies/puke.gif" border="0"> . the rebuild kits are a lot less spendy. you might call toyota and see what they have to offer and check out the net to see if there are places who sell remanufactured turbos. they you could probably pick up a warrenty with it! <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/frown.gif" border="0">

The CT20 turbo is not a very good unit. Have a look at Jeff's page for some good info on swapping it out for a Garret unit. The CT26 from a Supra may fit, and is also a better unit. I have a stock CT20 in good shape, if you want to buy it, e-mail me. [email protected]

I agree, but there are two versions of CT-26's. Get the Supra one, not the MR2 one. There may be some issues with fitting a downpipe also with the CT-26 because it sits on the passenger side normally on the Supra and you'd be putting it on the drivers side.. I've heard it being done, but all it takes is some fab work. IMHO, the CT-20 isn't worth being rebuilt. You do see CT-20's on Ebay once in a while tho. Because they are so rare, it'd be about a wash to swap to another turbo, probably the Garrett T3/T4.

saab has garret turbos on them. and they can really pump out some power. the saab's boost was near the red zone on the gauge. i was up to 140 mph. those turbos rock! i bet you could get a turbo out of a juck yard from a saab. the 1988 models had an intercooler as well. you would probably have to make your own header for it. the saabs also get their power aroud 1500 rpm all the way up to 4000 rpm. i really miss that car <IMG SRC="smilies/frown.gif" border="0"> <IMG SRC="smilies/crybaby2.gif" border="0">

I went with the T3/4 and an air/liquid Celica intercooler. Just fired it up yesterday, too bad the front end is not done yet.

The 16V Saab 900 Turbo uses a T28 (I think?)Garret/AirResearch unit. Different mounting flange. It would probably size up well for the 22RTE, though. You could always run twin turbos (though the 2.4 is a bit on small side for that).... my daily driver uses twins... oh so nice.

The factory turbo will come with a 12/12 warrenty, but for what the dealership wants for them, <IMG SRC="smilies/flipoff.gif" border="0"> . LC Engineering has the T3/4 too, but there again, <IMG SRC="smilies/flipoff.gif" border="0"> screw those prices!! Tell me more about the Supra turbo compatability. Will this turbo fall into factory parameters of the ECU? Are the injectors more or less than 295 on the Supra engine? Tell me more! <IMG SRC="smilies/eyemouth.gif" border="0">

Ok, The Supra CT-26 is bigger so presumably with more CFM and probably a little more lag. Here's a picture of the exhaust flanges side by side. They are the same width but different length and it looks like there's enough material on the CT26 flange to just elongate the holes. (Stock CT20 manifold is on top, and CT26 on bottom)


Also, you can see the differences between the exhaust routing in this picture <IMG SRC="smilies/frown.gif" border="0">CT20 on top)

That sucks, but its not surprising. Toyota turbo's are junk! If you want to salvage the truck get an after market turbo try TEC, there in Denver Co <IMG SRC="smilies/usa.gif" border="0">. I put one of their units on my 86 turbo 4runner and I'm very happy with it. <IMG SRC="smilies/tongue.gif" border="0"> For more info email [email protected] he knows how to get in touch with the boys there and he knows more that you ever want to know about turbos.

I disagree, the CT-20 is junk, but not all Toyota turbos. I know guys running CT-26's and are getting 500 HP out of 7M-GTE's. True they are more expensive to tweak because they are rarer. But they're not junk. Back up your statements NEWBIE!

Yeah, the CT20 that came on the trucks is a questionable unit at best. Small usually = good torque and little lag at the expense of high end... how Toyota managed to design that small laggy no high end unit is beyond me. I think some of the Celica GT4/Alltracs got a different CT20?

Your right. <IMG SRC="smilies/frown.gif" border="0"> You caught me slippin'. The CT-20 is really what I was talkin' about. Basically, any 86-87 pickup or 4runner with a factory turbo.

Might point out that it is probably a very good idea to run synthetic oil, regardless of the turbo you choose. Stands up to heat better, keeps turbo bearings cooler, and doesn't coke in the lines/bearings near as much as conventional oil. JMHO

i would assume that you are talking about a turbo for a gas powered engine?
if so than a turbo from a diesel would it be the same?
the tubo in my truck whines like a siren when it winds up ,most of the turbos i've heard all sound like that .
also the turbo in my truck is also antifreezed cooled as wellas oil cooled --is this a common way for all turbos? ROCKET

Most better turbos have oil and coolant lines going to them to help keep the temps down. The older Thunderbird turbo coupes had oil only cooling them and they tended to fry themselves prematurely. Also, it's a GREAT idea to run synthetics. See picture to the left!!
