I know this sounds stupid, but would a t518z 8cm work on an rb25?
reason being I have a new t518z (td05-18g) from my SR that just shat itself, and with the rb25 conversion rather than sell the turbo and cough up for something else.. im wondering if the t518z would go on the rb25? an adapter is no problem, just wondering about efficiency and response and the like.
it is suited to an sr, so It may run out of efficiency, but then again it is a quite sizable turbo for an sr (240kwish)
cheers
