The loom is much better to use the 2.4 one. Going to a dished flywheel is the cheaper way to do it. But I also can drill the much lighter flat flywheel for lh2. 4 which then needs a stronger clutch as the 8" disc will slip with boost.
Not entirely correct. Yes its true that you can get away with not having the speed sensor and use the LH2.2 throttle body but what happens is you have a car that can be a little difficult to start when cold and a car thats more likely to stall when the AC is on.
I did that exact thing with the 245 and while it works, its annoying. Also the car doesnt ever go into decel mode on cruise so everytime you let off the throttle it cracks and bangs out the exhaust from the unburnt fuel. Kinda cool and sounds like a racecar but gets old on a DD.
The people who havent hooked up the idle motor are those who are running track cars that dont ever idle or those who are happy to deal with the little oddities that will spring up from the fact the computer is unhappy about missing something.
Things that I've noticed in my swap which have been caused by the lack of idle motor are; constant 3-1-1 code being stored in the computer, unable to use larger than stock injectors as it runs super rich on idle and off idle cruise, harder to keep running when started cold and requires me to keep my foot on the accelerator until it warms up, jerky and boggy acceleration when cold, average fuel economy, noisy and droney on decel and when the efan kicks in the idle gets kind of rough.
All of these problems wouldnt be a problem for a car that is on the track but for a DD you dont want to deal with them everyday. Thats why ive found a late model diff with the sensor and im hooking it up properly.
