nope, didn't have any work performed by him.
i spoke with them about 2 options - rebuilding my current RB20DET, but with good internals, bigger turbo etc - he refused to do it, said it was a waste of his time.
so i asked him about performing an RB25DET conversion (with a fairly standard rebuild of the replacement RB25DET... just get everything balanced, forged pistons etc) - again, he didn't want to know about it, said that if it wasn't an RB26 he didn't want to know, as it's a waste of time
