      Not to be rude, but search, this website has tons of info and a lot guys will help when asking specific questions.

      So far all I've read from you is that you have asked basic questions without seaching here or google and you can do vinyl wraps; not of which instills confidence in doing this swap.

      Good luck.

        Not to be rude but I've searched for a week. I have found some helpful info, mainly now all I'm looking for is a parts list for an S50 swap. I'm still searching. I've also done all my work on every M3 I've owned, I'm just not familiar with E30's. Just hoping for some help man. Usually forum guys are a pretty good group and helpful (that's not a dig at you, I swear). I'm a very strong contributor on M3 forums even though I could tell guys to search but I help them out because this is my passion. Take that as it is, just a comment. Not meant to insult or offend anyone :)

          I would LOVE an S54 swap (too much $$) but if I go S50 with a supercharger, that should do the trick

                Thanks for the recommendations man. Again, I'm not into the E30 world (am now) and just needed directions.

                For those that search and find this thread, here you go:

                This thread is a great idea Ryan. It seems more and more people are becoming serious with the DOHC(M50/S50) engine swaps rather than just throwing a whim of a dream they had onto the forums. This is some very helpfull info that I saved a few months ago from Chuck Waits. Hope this can help.

                11. E30 diff. w/ 3:25 ratio or E28 533i w/ 3:25 LSD
                12. E30 318 ECU mount
                13. E34 oil pan
                14. E34 oil pickup
                ect. ect.
                15. E36 m3 exhaust manifold
                16. M50 radiator hoses
                17. E36 M3 Motronic
                18. OBDI intake manifold
                19. OBDI throttle body boot
                20. E36 alloy mounting arms
                21. OBDI wiring harness DO NOT BUY silver label “413” motronic, it has EWS (security),
                it can only put into original chassis
                22. the engine harness and the ECU are all E36 M3.
                On the standard E30 with M20 engine fitted, you have the large round plug (C101) up on the firewall next to the brake booster.
                This plug has 2 parts. One half is connected to the car wiring, and the other is connected to the engine harness.
                When the M20 was removed, the engine side of the plug was removed with the engine. Now I have the S50 half of the plug in its place. Although similar in appearance, it will not plug directly into the E30 half of the plug.
                I removed the E36 engine half of the plug, and replaced it with an E30 one. This then allows the 2 parts to screw back together. All you need to make sure is that you have the correct wires connected to each other. Its not just pin 1 to pin 1 and pin 2 to pin 2 etc (although some of the wires do actually connect this way).
                This plug connection is the only point where the E30 & E36 wiring interface with each other. The rest of the E36 M3 engine harness is totally self contained.

                23. the exhaust from the downpipe to the muffler is all custom made

                This is not a complete list but damn close if you need any additional info feel free to email or call me at
