Saint My life on the forum Joined: Dec 2005 Posts: 1,897 New Zealand	Just remember it is t3 exhaust flange so it won't fit the OE manifold. though I don't own one, I believe the GT3071/76 WG used a GT28 turbine wheel to give enough space for the intergrated wastegate, rather than an external gate model which uses the gt30 exhaust wheel - not 100% sure on this but fairly confident Figures speak for themselves though

Smaller than T3 flanged GT30 but bigger than GT2871 for example. The size is 56.5mm vs 60 mm for the T3 flanged version. Last edited by MiniPit; 03/12/2008 23:48.

Matty Unregistered M	I've heard that this turbo likes boost. Be warned though, it does suffer from boost creep so tread carefully.

Matty Unregistered M	Not bad for a big turbo. I'm making 1bar at 3.5k, and I'm on full boost around 4.3k.
