2005 Pontiac Grand Prix GXP LS4 DoD 4T65E TAPShift powertrain swap into a Pontiac Fiero


Donor motor, transmission, and related parts came out of a 2005 Grand Prix GXP courtesy of Ed Morad Parts Co. http://stores.ebay.com/Morad-Parts-Company




All of this will be going into a 1987 Fiero GT. The features that are planned to be included in the swap are:

-The transmission TAPShift function (steering wheel mounted shift paddles)
-DoD (displacement on demand) function in the engine
-And factory remote start / keyless entry / driver info center.


Phase 1 has been completed which was to port the cylinder heads in order to increase power output of the engine without sacrificing drivability or fuel economy. An aftermarket cam was considered as on option but no suitable affordable unit was available. Also the transmission has been gone thru by TripleEdgePerformance: http://www.tripleedgeperformance.com in order to install a shift improver kit and various fixes for known bugs.

Phase 2 is the mechanical and electrical aspects of the engine/transmission swap. The plan is to complete this phase and get the engine running before I move on to Phase 3.

Phase 3 is to install the BCM, DIC, and other modules we got from the Grand Prix in to the Fiero to see how much of it I can get working without too much trouble. There is currently no programming software available that can reprogram the BCM to remove certain functions so I imagine I will have a lot of work to do in order to "fool" certain inputs and outputs in order to prevent warning messages from being displayed on the DIC.
