RHD M52B28 project- E34 shopping list help please

[übersteuern]

After procrastinating for years, I've finally made the splurge and bought an M52B28 to drop into my RHD 1989 325i (similar to, and inspired by, drew325is' project). The plan is to keep it as stock as possible at this stage. Exciting! (scary...)

Could you please help with these questions:
(I have searched, sorry if the questions are repeated I just want to check they apply to RHD cars and M52 not just M50)

1) I'm gonna start chasing E34 bits. Throttle cable, sump, dipstick and tube: is there anything I've missed?
2) one project used the E34 alternator and power steering pump. Just wondering why the M52 parts won't work?
3) There's a guy on here who made Getrag 260 mounts for 24v, is he still doing this? Who is it, please?
4) The M52 is out of an auto donor car, what extra complications does this have? (eg is ECU replace/flash reqd?)
5) If I am keeping OBD-II, what stuff outside of the engine bay do I need from the E36? (eg O2 sensors? any other EWS stuff?)

Thanks!

why keep obdII?
obdI you gain performance and easier wiring.

white325is makes the trans brace, or you can run a g250 and have no issues.
someone on here started selling temp senders.

good luck.

You bastard. You outbid me on that motor! That's George's engine!:p

As far as actual tuning goes, OBD1 has no gain over OBD2, if anything its the opposite

Devon, thanks heaps for the info, I'll get in touch with white325i and look for temp sender sellers.

I'm getting my OBD1 vs OBD2 info from here: http://www.r3vlimited.com/board/show...36&postcount=1
My mechanic has done a swap in the past where he ran the E36 key hidden away (and permanently on) to keep the EWS happy. So I figured OBD2 would be easier, since I have all the bits. Tuning flexibility in the future would be nice, but the main thing is minimising wiring nightmares.

I deny all accusations ;)
When low km M52s come up, us E30 boys start circling like vultures!!

what about...

ECU - 413 red label
Oil Pan

1) I think that's all you need from the e34
2) I don't think you can use the e34 alternator or power steering pump. You need the e36 alternator and e30 or e36 steering rack. If you can find an e36 rack the ratio is much better than the e30.
4) Doesn't need a flash, but I think you have to hook up a couple of wires to trick the ECU into thinking the car is in park to get it started. Someone else should chime in with this info.
5) I say stay OBDII, it's cheaper and easier if you have access to all the parts. Here is what you will need:

Engine
Wiring harness
Matching ECU, EWS system and key
EWS system contains 2 boxes, the key and key ring
Front 2 O2 sensors (rear 2 not needed)
Oil separator - you will need to add a drain to the e34 oil tube or run the drain from the bottom of the separator to an oil catch can

I think that's all you really need. The wiring isn't any different/harder than wiring OBDI. If you need help with wiring let me know as I have OBDII M52 diagrams for an 87 325e and a 91 318is.

The e36 wiring harness has a longer tail to the ECU,so it fits better in the glove compartment. Good luck...:)

Thanks heaps for the info, Blue Devil and luckysnafu and Dan. :up:

I've grown used to the sloooow E30 steering, so I'll leave it there for the time being.

if you have to gtet header work done may aswell put the e36 rack in while you can. it really transforms the car..

[übersteuern]

Hmmm...you're right it makes sense to do it now instead of later. Any tips on what works with the M52 (eg do certain racks create less clearance hassles)? Or is it just a case of getting the headers built to suit the steering?

[Leo_328i]

Any E36 standard rack will do great.

They are all the same in RHD markets with the exception of the 3.0l M3 which uses a different rack. 3.2l M3 uses the same rack as every other car.

[Wanganstyle]

in us market the 3.2 m3 has a limited travel 328i rack, so its shorter lock to lock because its not allowed to move as much

how do you have clearance for headers and the brake booster, since they're all coming out of the right hand of the firewall? kinda curious how it all goes together, seeing as the steering column is next to the exhaust

Brake booster is on the left side, yes even though it's Right Hand Drive. As you can imagine, there's some nasty linkages needed to make this happen.
