BenDoCo- cost $500, could've done a turbo side intake cheaper with better performance. Works well for what it is, but wouldn't buy on again. FiftyOne - thanks for the concern, think the bearings will fail before the compressor wheel though. Hopefully a while before that happens. Arronm - definitely need wider/stickier rears =P P91 - not for the moment, if I'm honest current power levels exceed my skill level, working on handling mods and getting some experience. I'm also 20hp off the maximum power recommended for the diff and 250nM more torque than the gearbox is rated to, so if I push the ceiling much further, I will have a huge bill on my hands. If I have to change turbo, will probably go gtx3576, modest tune with better spool, and start saving for driveshafts and cvs.
