Hey guys, so I am getting ready to take care of a few things on my 1994 540i auto. As of now not a bolt has been removed from the car.
So, s62 swap... I want an s62 e34 as a dream car and I found an s62 from a guy who parts out wrecked e39 m5's. I asked him how much, he gave back a good price so I bought it. Now I'm committed >:] The initial plan was an m60/m62 hybrid as my #6 cylinder has low compression along with a 6 speed conversion.
So what's been done, I have an s62 in my garage now. Forgive the quality, I did not bring a real camera.
As a more complete plan the car I have an s62, the 6 speed from the same car, and its ecu. I will have the ecu reprogrammed to remove the ews and other system that will not interface with the e34 chassis. That being said, I am not grabbing the e39 gauge cluster or other interior components. As part of getting the ecu reprogrammed, it will be made to work with the e34 hardware with an adapter harness. Being a 94 540i auto, I have an open diff. That will need to change but I only need the internals. The 540i auto already has 3.15 gears like the e39 m5 so any e21, e32, e34 large case diff will work as at most I will just gut it for the internals. I do want to investigate if the internals of an e39 large case lsd will work. If so, I can just grab the internals from the same person I got the engine from so I can have a matching diff.
The driveshaft will just be cut and balanced. I'm not gonna go through the process of finding an e34 6 speed driveshaft.
The suspension is currently on H&R springs and stock everything else. I will be changing that to coil overs. I haven't decided which yet but I want adjustable damping ones. I have that on my e30 and I love it. Ideally, I will grab springs softer that the H&R with stiffer sway bars. I am not positive with that idea but that logic is coming from my experiences with my e30. Either way, more research will happen later when I am ready to work on that part.
The e34 exhaust should bolt right up but... mine is full of holes and rust sooooooooo.... ima build one. I have a friend who knows how and wants to weld. Annoyingly, finding performance headers for v8 e34s is stupid expensive (for what I found) so I'll mock up a set and build it.
Brakes will be fairly simple. I will grab 8 series front brakes and get a good set of pads and rotors.
The wheels are e38 m-pars with continental tires.
After that there will just be minor things to check/fix/do like fix the HVAC, auto to manual conversion, rust repair/body work, seals, etc...
That's where I'm at. Have any ideas or advice feel free to submit them and I will be updating this thread as progress is made.
