Since im on a tight budget im building a RB25DE+T, ive based my build off the 25DET itself. ECU wise, does the 25DET factory ecu plug into the 25DE engine loom? And the loom is a Auto one, any differences? Same with Auto/Manual ECU do I need to be picky? Any other suggestions welcome, so far the build consists of a RB25DE, with everything off a 25DET bolted on etc. Other thing was this is going into a Manual Swapped 20e Cefiro, so if anyone has some infomation on what wiring needs done id appreciate it. From what I have read some things just work, some sensors need modifying so they come up on the dash, so yeah things like Rev counter etc what is the overall deal with the wiring.
