Thinking about de-turboing my wagon when I get ANOTHER new engine for it. Plans would be an SPFI short block and MPFI turbo heads with the oil and coolant lines for the turbo sealed off. Aside from yanking the turbo and getting a Y pipe or something, what else would I need to change besides the ECU? Thanks..

I have heard that the MPFI and Turbo use the same ECU, and on one of the two, two pins are connected at teh computer to load the Turbo fuel map. (hmmm.. maybe If I wired that to a transistor, wired to the boost light, so that the ECU only went into Turbo mode after the turbo kicked in, I wouldn't get such crappy mileage.......)

Sounds like fun :)

Instead of plugging the oil and coolant lines why not just route in some coolers?
