I have a 2004 manual with a DE engine in it and it runs great. Bought a 2006 automatic that had a blown DE in it. Found a engine and when I got there to get it realized it was a revup. Bought the engine with wiring harness and ECU. What I have read is the revup only came in manual transmission cars. The way I see it I'm going to have to take the engine out of my 2004 and put it in 2006 and put the revup engine I just bought in the manual transmission 2004.will I need anything more than the wiring harness and ECU. By changing the ECU will I have to have my key reprogrammed? Thanks for any answers you may can give.
