I`ve only got a t34, im just about finished my rebuild, low comp pistons 7-2-1 cr, rs 500 cooler, breather system, big filter, stainless exhaust, swirl pot, all samco`s, 044 pump, and my head has been buffed up a good bit, just the usual kind of stuff. i would like a reliable 350bhp, so hopefully my turbo holds on which is probably the next thing to change
