you don't need a front mount if you don't plan on running a lot of boost. an upgraded top mount would help though.

ported wastegate is a good reliability mod

Everything I've heard about reliability on the turbo involves preventing detonation which means lower compressed charge temperatures. More boost means higher temps simply from compressing air (even without any waste heat). The main way to counter that is to spray in extra fuel (beyond what gets burnt). That means tuning, adequete fuel delivery, injectors, etc.

There's also an auxillary injection section of the forums for cooling with water or alcohol, if you want to get extreme.

All this advice seems helpful. I guess I'm gonna start looking for a wideband. Any fuel or ignition upgrades? Would it be too early to upgrade to a bnr stage 1 or stage 2? Thanks for the help so far.
