THE CAM POSITION SENSOR IS PART OF THE DISTRIBUTER, AND CANNOT BE SERVICED
No, It will only fit Toyota 4efe (starlet), 5efe(paseo), 5efhe(sera). 4afe is a different head.
To turbo a 5efhe your best option would be to Forged roads for a normal 5efe Forged Piston's for a 4efte Manifold to suit a 4efte turbo to suit manifold Downpipe to suit turbo Oil sump and oil filter housing off a 4efte 4efte rocker cover and inlet (makes pipework easie) Use engine loom from a 4efte and ecu from a 4efte Gearbox and shaft are of the same size the 4efte shafts have bigger cv joints on them.. This is the basic there is loads more you can do for more power etc :) Hope this helps
3e-e, 5efe, 5efhe, 4efte, 3ete, will all bolt up and be the cheapest. a 4age, 4agze, or 3sgte will fit with some frame modifications. basically you can put in any motor that will fit in the engine bay if you got enough cash.
