I´ve done it a few times, no problem at all. I´ve used T3 flanges and added a T2 bolt pattern combined with conical bolt heads. You need to make sure the T2 bolts get under the flange surface.originalsin wrote:have any s13 guys modified the stock manifold to accept a t3?
There are better "bolt on" flanges out there now with two flanges and a cone between them. T2 -> cone -> T3.
Hard to explain this stuff in bad English...
