Hey! I've got 2 dead 2GR's and a fully dressed 4GRFSE to play with, umming and arring what to do. I had done all my measurements originally off a 2GRFE, and the mechanical drive fuel pump has been quite an obsticale when it comes to brake boosters in my granny spec KE70 corolla.
I think the shear mass of the loom and the smartkey means that the easiest way to go is to get it to run is an adaptronic E1280 ECU for the injection and lose about 10kg of wiring and regain and under the dash fitment of the ecu. I've got all the bits to make the engine run, but I think fault code city with a W58 will be too much of a battle.
