we'll i see it as a cirtan power level is never good enough lol, so why not go the slightly bigger and have that scope for when the time comes, + garrett turbo's are generally very reliable
and 3g's is a veryyy good price, what about aftermarket managment as well?
you talked to GCG turbo's. there probably able to rebuild and put gt30 internals in your ct20b,
i researched this a fair bit when i was thinking about a chaser,
