I just got hold of a 1985 240 with an m46 to do a swap in my drift project, a 1990 aw70 car I've had for a while, and need to get it done in a timely manner and without much more investment. I've been searching hard to find some info about this, but couldn't find any answers that left me with a solid plan.
The donor car has 250k miles (wont likely be a long term trans), while my 90' has about 180k, so I wanted to keep the current engine in the car, and it would avoid any potentially annoying wiring that I'd need to do. I have read that I need an LH2.4 flywheel and a new clutch obviously to go with that in order to use a crank position sensor, as well as drilling/knocking out a spot on the bell housing for the sensor.
Is there any way I can circumvent the need for a new flywheel? I am now debating just swapping the entire engine over instead, but then I'll have to do another AC delete, take my new water pump off my current engine, and probably transfer the ECU/EZK and harnesses over, which is going to be a lot more work than just swapping the transmission, and will leave me with a powerplant likely to fail me a lot sooner than my current one.
That leads me to my second question. This in particular probably has better info I can still find, but how much is different between the two harnesses? Would it be possible for me to retain my current harness to avoid a lot of extra swapping of wires, or is my assumption correct that it would be easier to reroute all the wiring from the donor car, since there are likely connector changes and extra wires on the LH2.4 system? I appreciate anyone's knowledge who can lead me on the simplest path to swapping all this stuff around. I can't wait to finally get rid of the AW, it's been a long time coming!
