50 trim in - lot's of smoke from exhaust

[BKs50trimGST]

and shidley is also trying to save me money, because u can't just drop in a 6 bolt into a 2g can you? you have to modify a couple things and that costs money, i'll probably be saving myself a couple grand just rebuilding the 7 bolt and leaving it at that, basically all i want is an engine that is basically brand new, rebuilding it will do that, i buy performance internals and the car will be able to handle the 50 trim for a longtime, correct?
