antil33t 90 Report post Posted May 1, 2013 (edited) Need all the electrics, ecu, loom ect to put an M52 Into an E30. Engine is from an E39 528i so ugh the loom is basically useless. Also require engine arms (E36??? M52B28?) Mounts I'll buy brand new, uhm... what else? I might need an M50B25 fuel rail, but I'll see what the one I'm getting has first. I have 8 months to finish this car, and drive it to Auckland... Edited May 1, 2013 by antil33t Quote Share this post Link to post Share on other sites
polley 916 Report post Posted May 2, 2013 Have you decided if you're going odb1 or odb2? Once you have all the parts, it's an easy conversion. What are you doing for brake booster? Quote Share this post Link to post Share on other sites
antil33t 90 Report post Posted May 2, 2013 Can't be f**ked going OBD2... will be going OBDI. Probably going to move it? all the other options look painful to get. Quote Share this post Link to post Share on other sites
polley 916 Report post Posted May 2, 2013 Well I've got a ODB1 405 ECU and air flow meter here I'm never gonna use, but that wont run your vanos. Moving it sounds like a bit of work, be interesting to see what you come up with. I've used E32 / E34 vacuum boosters on every setup I've done, but they are becoming a bit hard to find now. The brakes are much better than standard with the larger master cylinder and it pretty much bolts right in, just need to make some new brake lines and I like to run it through a proportioning valve as it can brake a bit hard in the rear at times. Theres a 94 520i at mangere pick a part, could be a good donor for ODB1 parts (loom, ecu etc), just reflash the ECU to 325 eeprom. Quote Share this post Link to post Share on other sites

Probably going to move it? all the other options look painful to get. is a porsche wrecker up the line from me, was quite competitive. i used a Porsche 944 Booster. but if i did it again i would import an E30 iX one i think or see if the factory E34 V8 one would work. would be easier than slotting the firewall and moving the E30 one across edit: troy bet me to it Edited May 2, 2013 by _Ethrty-Andy_ Quote Share this post Link to post Share on other sites
polley 916 Report post Posted May 2, 2013 Yup, E34 V8 one mounted to firewall is what I use. If you use it, you need to get the mounting bracket that goes with it. I lightly slot the holes in the bracket so it moves the booster down and across, then do the same to the firewall. My booster sits pretty much right against the strut tower and about 1 inch clearance between booster and manifold. Slotting it isnt a big deal, only takes 10mins.

e30ftw 396 Report post Posted May 5, 2013 Mk1 Golf booster bolts straight in using same Master Cyl and everything and it's a smaller overall diameter. You just get slightly less brake assistance. Quote Share this post Link to post Share on other sites

It was ment to be I tells ya! you talking about the alpina one someone posted up? yeah but its a 535i not 525i. if it was, this is really not a bad idea at all. dont think it had the alpine rear kit though just front and sides.

And in an e30 with horrible brakes to start with... thats pretty suckfull. Quote Share this post Link to post Share on other sites
euroriffic 601 Report post Posted May 6, 2013 Yea that's the one, and no matching skirts and rear. but remember his touring is a m50b25 so can use that computer and loom for the e30 Quote Share this post Link to post Share on other sites
antil33t 90 Report post Posted May 6, 2013 Nah, I'd never put anything other than an M5x in the E34. not interested in M30's lol. it's not tidy enough to worry about making awesome. Quote Share this post Link to post Share on other sites
BMRBOI 8 Report post Posted May 7, 2013 What do you need to use for temp sensors on the M52 to OB1? Ive read somewhere you need to splice wires as the m52 has one four wire temp sensor and the m50 has two? Also the timing cover has different coolant connections? The sumps are different in an m50 and m52 also (the dipstick area). Could be wrong... Quote Share this post Link to post Share on other sites

The sumps are different in an m50 and m52 also (the dipstick area). Could be wrong... correct, need to tap into the head and install a separate sensor. unless your name is Josh (Hybrid) probably not easily doable. Timing cover has same coolant connections in my experience only metal on a non vanos M50 and plastic on the rest. need M50E34 sump dipstick tube and dipstick, and also the mounting hardware. if its off a very late E34 then it may have a bracket on the dipstick for some of the emissions gear, dont worry about that Quote Share this post Link to post Share on other sites
