thanks for the replys but i also have 2 studs and 2 bolts but im going to have to pull the studs out for my adaptor plate and replace them with allen headed bolts
The 2k engine I picked up has 2 studs in the manifold and 2 studs (not bolts) in the turbine housing. Its the one with the wastegate actuator on the compressor housing (HX35). Both of my 98's, as well as my 94 have four studs in the manifold.
