Did th eCT20 need rebuilding or was it in good shape? 250 + shipping is right around what I could spend without too much ass chewing from the woman in charge.
250+ shipping was a rebuilt CT20 with new center cartridge installed. The used TEC kit would have been ~800 and then another ~300-350 for the 2.5" exhaust that it needs too. The CT20 was the quickest and cheapest way (for me) to get the truck back on the road for the summer.
If you have time, below are directions that went around the 22RTE list a few months ago on installing a CT26 onto your motor. Does not look all that bad either..
I did not write these directions- so please don't ask me questions. Just passing info along...
---------------
When I bought my 1987 Toyota Truck with a 22RTE engine it had a dead CT20 turbo. This is how I installed a CT26. I got a CT26 of off ebay. I had to grind the mounting holes on the exhaust housing towards the center. This allows it to fit on the 22RTE exhaust manifold. I ported the exhaust manifold while I was at it especially the outlet using the CT20 gasket as a template. The inlet of the CT26 is about the same size as the hole in the gasket.
Now take apart the turbo and clock the three sections to fit the truck. I put the manifold on the truck with just the exhaust housing then put the center section so that the oil feed/drain port pointed straight down and marked the 2 sections to put them together later. The compressor housing outlet is rotated also to a 45 degree angle looking from the front of the truck. There are some pins between the sections that have to be removed.
The wastegate actuator from the CT26 works but you need to bend the rod a little differently.
Then I took the Supra feed/drain line and the 22RTE feed/drain line and made one from the two. I used the 22RTE drain flange and pipe that go to the block but the flange that goes to the turbo is from the Supra and I retained the feed line that comes out of it. But then I had to use the banjo fitting on the feed line from the 22RTE and solder it on the Supra feed line so it will fit the feed port on the block.
I took the intake pipe from the CT20 to the throttle body and cut off the flange that bolts onto the CT20. The pipe is 2 pieces so I ground off the weld and took that flange and short section of curved pipe out. Then I welded in a short straight piece of 2"OD pipe. I got a radiator hose with a 45-degree bend in it for the time being to connect the turbo to the pipe. Got that, 45 degree turbo outlet plus 45 degree hose equals pointing up to the intake pipe.
Alright, next was the lower coolant pipe. The larger turbo hits it. I got a "Cool Flex" pipe which is a bendable pipe and I re-routed it. The hose that connects to the water pump, I took and trimmed it in half. There is a return line from the heater core so I retained that portion and connected the “Cool Flex” into the hose. Then I routed it back around the engine mount and forward to a straight hose into the radiator.
Now from the air cleaner to the turbo I used the stock setup but with modification. From the AFM on top of the air box there is a long hose, a short section of pipe and then a 90-degree hose that goes to the turbo inlet. The CT20 inlet is a smaller OD than the CT26. But on my truck that 90-degree hose is 2 pieces. Like a laminated construction. I pulled out the inner hose and trimmed it back because the outer hose fits nicely on the CT26. But you need that inner part for that short section of tube. I glued it back in with some silicone gasket maker.
Finally a custom made down pipe. I got a 180-degree U bend, 2.5" OD pipe with a fairly tight bend radius and chopped it into 2 90's. I had a flange made. I couldn't find one but I know they are out there. Mine is a rectangle with the four mounting holes and one 2.5" inch hole. With the flange on I put one 90 going straight down and then the other goes straight back. It has O2 sensor bung welded in just behind the flange.
For the exhaust I got a braided flex pipe to connect to the downpipe to take some stress off of it. From the flex pipe it is a straight piece of tube, a Super Turbo on end and that takes it over the axle and then a straight pipe with a downturn at the end.
