Its a GTST
He was told it started life as a normal (non turbo) one and had an engine swap, but that might not really be the case if they did the GTST as 4wd anyway.
He is looking to get more power from the engine, and i said i would be concerned aobut the box if it wasnt a GTR one, but obviously from what you are saying its not an issue with the gearbox and he can happily gas the bollocks out of the engine without worrying about the 4wd system breaking
What are the RB25 internals like, you got any links to details of them?
I know the turbos shit themseleves before they even get to a bar, but how are the pistons for extra power?
