Re: El-cheapo performance
the main differences that i have found and know of for sure(no one in the know is willing to cough up the info i want) is that they run a different ecu, cam, injectors, compression, and fuel pressure reg.
the fuel pressure runs at 300 Kpa whereas a normal I6 runs at 250Kpa. if u use the standard ecu with a xr6 pressure reg it will think the pressure is of standard and inject fuel accordingly which causes all kinds of problems such as flooding when cold, heaps of black smoke on accel and shithouse fuel economy. i dont know the exact figures but the xr6 injectors are also very slightly higher flowing. compression and cam speak for themselves.
