Long story short me and a friend are both trying to do s52 swaps into our e30s, unfortunately we both are idiot's and can't seem to find a complete list of EVERYTHING we need for the swap, so if anyone is willing to post a complete parts list for an obd2 s52 swap then i will paypal the first person with a complete list 20$ us. thanks for the help!! (probably going to get flamed for this but this is really our last resort lol)

i have no idea what i am doing with my life -
Indeed, keep your money. It all depends on what YOU want to do. Start with the S52, the wiring harness and the ECU for it. Do you want to relocate the brake booster or go with a different one? How do you want to run your exhaust? it all depends brother. plan your own swap, and youll be happier with it. I recommend going with a late E30 radiator and expansion take if you have an early model car. I also highly recommend the long tube headers from ebay for the s52. they will be about $100 shipped. Im going to make my parts list soon for what I used, so when i finish it, ill send it your way.Comment

Since you got your list x3, I'm going to expect a kick-ass engine swap write up soon!Comment

I've read about a few different approaches to the brake booster issue.
1) E21 booster/porsche 924/944 booster
2) 325ix booster
3) shifting the booster to the left
4) booster delete plate by MassiveComment

I relocated my booster, but I have a lot of tools at my disposal. If you don't have a lot of tools, I would recommend taking a different "bolt-on" route. I should write a swap thread... I didn't document mine nearly well enough. I'm typing up my excel cost spreadsheet now.
This is one of the best resources out there:

I reflashed my own ECU to keep OBD II. The muffler flap valve, fuel tank sensor and all of that is horse shit from what I've seen. (it is contained within the values of other things that you already change... and this "extra modification" costs you $50 each to get rid of when you literally do not modify different bytes of code. I'm no expert on this, but mine works fine so far with no CEL's. I did actively erase the SAP section of the code, the EWS driveaway protection and the rear O2 sensors. I wrote a thread on how to reflash, but you'll need an OBDII E36 to plug your ECU into to reflash and a cable or two, or make your own bench rig. I'll tell you what, If you aren't in a huge hurry, (the next month or so) I'll rebuild a bench rig and reflash your ECU for you for cheap. I need to get into that again anyway. If you need it done quicker than that, be sure to shop around. PM me and I'll send you to the right people.
As for some other things. The link that "isnt working" due to a copying error, is in one thread that dirtbag30 sent you, as the first links in the first post. Just google "e30dohc wiki" and you'll find it.
If you go with the ZF Trans, you don't have to modify the shifter support arm and rotate it 10 degrees. If you stick with the 260 trans, you can I believe use the E30 Driveshaft, and you can definitely use your rear diff if its a lsd and you like it. But you need to modify the shift linkage and twist it 10 degrees. You can use the standard E30 manual trans brace with the ZF, no modification needed.
I attached a .pdf version of my excel spreadsheet so far. This definitely doesn't include all of the little things I bought like wiring shrink wrap, connectors, etc, but its a good start. Some is not necessary for the swap, like my suspension setup. I hope this helps.
I feel like some of this wasn't clear. I'm sorry if its not, I'm pretty tired.Comment
