      Um the TPS and IAC do not need to be changed.

      And you do not need to really "modify" just move things to different locations.

        The TPS is alittle different in appeacans but it works fine. Also the coolant sensor should be the new 3 way design wich works fine also. Same color wires. The Rest of the engine usues identicle sensors. True the IAC and TPS wires have to be lengthend. Also the DIS wiring has to be lengthend to about 8feet and go over the top of the engeine. Providing you wiring runs the same as on my car. This is all if you want to use the whole motor. Congratulations Karl! As far as the bottom end, What exaclty went bad on it? BTW Thats how much I got my engine for but it was less the upper intake, exhaust manifolds, and sensors.
