I have 1st generation 1g-gte (water/air I/C) in a T-18, the turbos are fairly well cactus, they are CT12 but had no part numbers on them, i got some numbers off toyodiy for a gx71 which is what my engine is out of (front sump). I rang my local toyota dealer who have helped me out with some bits for it before, i didnt tell them the numbers i found on toyodiy but a few hours later they came back to me with the same numbers 17201-70010 & 17208-70010.
I dont really want to pay $1000 each turbo locally for rebuilds as its just not worth it.
I have found replacement cartridges to suit the 17201-70010 but not much info about the 17208-70010, both turbos look identical except the housings are reversed, the rear turbo comp faces the back and tfront turbo comp faces the fro t, would i be correct in assuming the two cartridges would be the same its just the housings are different? The sites selling the cartridges list them for CT12C?

Not a hell of a lot of info i can find on the gen 1 turbos
