Jacko 2154 Report post Posted July 31, 2010 (edited) The before pics. M50B25 swap from an E34 All new bushes, likely some new springs, shocks, and sway bars from a 325 and new sloted rotors, And then she'll go in to get some minor rust removed, and panel and paint. And if I can find a new dash, wheels, and some sports seats in the process theyll be thrown in So far all ive got is a clutch, an engine stand, and workshop space organised The badge on the bonnet pic kinda sums up the states of the old girl Edited August 24, 2010 by Jacko Quote Share this post Link to post Share on other sites
Jono51 59 Report post Posted August 1, 2010 m50b25 is easier and a cheaper option, got one available with the correct sump,complete with wiring loom ECU etc could make up a conversion package, make a list of what you need and give me a call cheers Jon Quote Share this post Link to post Share on other sites

Jacko 2154 Report post Posted August 1, 2010 Shweet as, Ill give u a buzz tommorrow Jon, got a list going together at the moment (including floor mats and spots - cheers) . Need to go measure my sway bars up and make sure theyre havent been replaced with 325 ones, the more I dig into the my e30 the more bits I find that arent original Gonna go hire a steam cleaner for a few days during the swap, 25 years of crud too remove The end goal, long way off!, is something like this - Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted August 1, 2010 Just measured up my sway bars, hard to get accurate sizes with the verniers while jamming self under car Front is ~21mm, rear is ~14.5mm which makes them Mtech package sway bars anyway? Quote Share this post Link to post Share on other sites
Cale 36 Report post Posted August 2, 2010 I think the Mtech sway bar sizes are: front 20mm, rear 14.5mm. Quote Share this post Link to post Share on other sites

Jacko 2154 Report post Posted August 4, 2010 (edited) I just realised I forgot something, googling has turned up jack. Can someone point me some info on going to an electric fan setup, 16" sounds like the biggest that fits. But what thermoswitches do i need to control it? and where do they screw into? Using an E36 radiator/M50B25 The fan/relay wiring is all shweet, but what makes it go click? I feel thick asking this, im sure the answer is simple and ive just over looked it... Other than that I think I have all the 12 peices of paper, covered in p/n's and notes for the swap, under control....maybe Edited August 4, 2010 by Jacko Quote Share this post Link to post Share on other sites

E34 sump/pickup/dipstick E34 Wiring loom and ECU (auto) Brake booster E36 engine mount arms E28 M5 mount rubbers E34 throttle cable E36 radiator and hoses A good fella too machine the 260's flywheel New seals for the Getrag 260 Kevlar clutch kit Electric fan kit Custom headers, complete new exhaust (single) Modified GB crossmember Driveshaft hoops Cold air intake box (im gonna make one outta 2024T3 ali) and K&N pod All new gaskets/waterpump to freshen up the M50 Z3 shifter and new bushes All the nolathane bushes for the suspension New floor mats and spots Hope to go pick up most of it on Saturday, if it all fits in the ute. Still to sort out - LSD, New brake rotors and pads, And some decent front seats that arent spewing their internals all over my ass. Anyone tried one of the Ebay ECU chips? are they rubbish? Any recommendations on Gearbox, engine, brake fluids? Anything obvious ive over looked? Edited August 5, 2010 by Jacko Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted August 7, 2010 (edited) We have a new Donk, cheers to Brent and the guys European car parts for playing "find this bit" and answering all my emails! Picked up this morning, On the engine stand and stripped in the arvo. A few of the more interesting pics below, I took a bucketload of photos of the breakdown too help me stick it all back together. Managed to wind all but two of the exhaust studs outta the head, and three of the coils plugs are busted. Easy fix stuff. Outside of engine is a mess, inside it looks minta! Just waiting on an E36 manual radiator (going for a new one) a suitable brake booster and all the new seals/idlers/gaskets etc. Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Edited August 7, 2010 by Jacko Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted August 9, 2010 Spent about 6hours degreasing and cleaning all the crap outta it today, looks like an engine again! Pulled all the plugs and dropped the sump, had a good poke around, everything looks dandy. Rocker cover is off to be acid dipped and powder coated, probably get a few other bits done later Ordered a new chip for the DME, euro spec'd, good for a few more horses and torques and raised rev limiter. Will post up a comparison between stock and the race chip once its in. See if it was worth the $70 it cost, cheap as chips Too anyone who has done the swap before, can you remember the p/n of the grooved belt you used? Power steering and Air/con have been removed, so I need me a smaller belt. Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted August 11, 2010 Looking at RealOEM, seems like one belt drives the waterpump/alternator and one drives the A/C and P/S, I never saw the engine with belts on . So p/n 11281735190 is the belt I want.. Maybe I also just realised I have no O2 sensor is P/n 11781735710 what Im after? Where does it plug into the loom and is the wiring length critical?

Looking good btw! your so orginised haha can't wait to see the final product! I think the right combo is E28 mounts (the rubbers) from what ive read the other rubbers sit the engine two high or two low, and E36 arms bolted too the block. I dunno about organised ha. But every E30/M50 swap ive read seems to be incomplete, some points missing etc, maybe its obvious stuff to pros, and some cars never seem to have ever started So hopefully I can get it all down here, and have the thing start and run shweet first pop (thats the plan!) Spent the last few hours going through Realoem, working out all the p/n's for "refreshing" and replacing all the perishable stuff on a non vanos E34 M50B25, radiator hoses are E36.

pureboiracer 0 Report post Posted August 11, 2010 i noticed you mentioned about deleting p.steering. just to let you know you can get adaptors from places such as hydralink to convert the hoses into the e36 pump. and to confirm with jacko it is the e28 rubber mounts with teh e36 alloy arms, Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted August 11, 2010 New Question. Since my E30 doesnt have an O2 sensor, it also has no 02 sensor heater relay, what is used to control it, or do I need to pick up one of these too? Quote Share this post Link to post Share on other sites

BM WORLD 1283 Report post Posted August 11, 2010 good work. i dont think you will need the O2 sensors as the ecu i gave you is from the early ones which some didn't even run o2 sensors , but if you do want some we have some here . they plug into the 4 pin plug thats sits down by the starter motor and go back to the first section of the front half of the exhaust system. you have the corect mounts , e36 ali mouting arms with e28 style rubber mounts . keep up th good work Quote Share this post Link to post Share on other sites

It sounds like the DME ignores it till its up to temperature, So I guess it'd still run without it, but wont tweak the mixture. Since the intake and the exhaust on mine are gonna be way different from stock, and ive got a an aftermarket chip to swap into the DME, I think ill hook it up just for peace of mind that its not leaning out or doing anything dumb! Ill grab a new one I think, just to be "sure" its working right. What I may need though is a chunk of exhaust with the right fitting for screwing the sensor into though, so I can hack it off and graft it onto the new exhaust. Ill check with the guy doing it, I dunno if you can buy the 02 fittings off the shelf, like you can new flanges? Also noticed that the DME I got has got 1991 525i written on it, but the DME was manufactured in 96. I bet that cost a bomb to replace in the original E34!

BM WORLD 1283 Report post Posted August 12, 2010 no problem , we have some exhaust here you can grab and sensors etc if needed , they dont often fail . and yes i think there was a recall or reprogram on all those ecu's back then . every one seams to have a replacement sticker on them .

Cool beans, sounds like its easy to get off the shelf threaded oxy sensor fittings too! One thing I havent sorted out is a muffler, any recommendations? Something a bit stealthy, not a big shiny tin can with an 8" hole in the back (and a skank whistle to go with it, Whoooom psssh!) To get to the stage of the engine in the car running, new exhaust and headers, all new seals/radiator/clutch and other bits (with mostly OEM/genuine new parts) budget is looking at around $5k for everything. And theres another $3k in new wheels,tyres and LSD and nolathane, still havent decided on what to wheels. Those new BBS 17" weave clones look pretty slick, but so do a set of the cloned 17" Alpinas... Tough decisions. $1k on the interior for some new seats and a tidy up im figuring. Add another $5k in panel and paint (gonna keep it the stock schwarz black), im banking on there being hidden rust (those E30 sunroof pics scare me!), and the rubbish paint that is on it is gonna take a shedload of prep work. For a car that cost me $2k 3 years ago as work hack, its getting one expensive birthday I need to do some OT!! Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted August 14, 2010 Is anyone able to hook me up with a copy of the WDM/ETM for a 1985 323? I can find jack online, or on ebay. None of the M50 to E30 wiring diagrams ive found match up with my car. Email a PDF, or if can borrow a hardcopy to photocopy the bits I want, Ill buy beer! Seems like BMW liked to change the E30's wiring every year just for the fun of it. Quote Share this post Link to post Share on other sites
