1988 BMW 6-Series Description

1988 BMW 635csi M conversion.
This is a project car, currently in process of converting to a M52 M3 engine and transmission.
You will not need any parts for this project, everything is available and included in this sale (except exhaust).
The donor vehicle is a 1998 BMW M3 convertible with 108K, the vehicle was in running and driving condition after a mild right front collision.
The shell vehicle is a beautiful 1988 BMW 635CSI with 214K.
White exterior with beige leather interior. Body is an accident free. Rust effected areas are: one small spot in rear wheel well and under tail lights.
Interior is in great shape, leather is in usable condition, dash has one crack in plastic.
So far completed:
1. Engine and transmission were installed (with M50 oil pan and oil pump from e34 to fit over the steering linkages).
2. Right motor mount and bracket was fitted.
3. Rear transmission mount was fitted.
4. ABS module was removed for engine clearance.
5. Brake lines re-routed and brakes bled.
6. Drive shaft cut shorter and re welded (needs to be balanced)
To be done:
1. Left motor mount, and bracket (parts are available)
2. Exhaust (rear manifold needs to be removed and re-shaped by cutting and weldin, rest of exhaust to be fabricated)
3. AC lines need to be fabricated.
4. Power steering lines need to be fabricated.

5. Engine needed to be re-wired.
My idea was to wire an engine and transmission with its own wire harness and ECM/TCM to run as a stand along OBDII power plant. Complete wire harness and modules are included in this sale. I have everything you will need to finish this project. Your time is the only investment required.The other option is to convert an engine with OBDI set up. I will provide you with all the conversion schematics you will need in the future.
The vehicle is in non running condition there-so needed to be towed. We can assist you with the tow locally and long distance.
