i am thinking of using the ct26 steel wheel turbo from 7m or st165 because it needs minimal mods to fit. what about the ct20-b from the st185, how similar is it to the ct20? any other suggestions or advice on an upgrade for a 3tgte turbo?
The CT20A and CT20B have no similarities to the old CT20. The CT26 fits with minimal mods; it's been discussed many times before so you should be able to find the details with a small amount of effort.
