Someone help me, please.

whats the problem? also can you be more specific on the swap info on the swap.
motor m52 check
trans?
obd1? if so dme and harness? do you have an adapter for it?
how far are you and what do you have left?
and lastly what can I help you with?

Okay, here comes a long post. Hopefully I can be clear. I am staying obd2, but the wiring I purchased a swap harness and I have all of the EWS and DME stuff from the parts car(I think.) So the harness I got has instructions for that stuff.

1) What is this thing even? It was from the e36 and it seems like something I wouldn't need. But maybe I need it for obd2?


2)These look like auto trans stuff and can be ignored. (inside each of the round plugs there are 4 pins)


3)This appears to be some vac box (so it says on the side of it) and there is a thin line coming off the back. It looks like maybe it coudl go to teh charcoal canister (which I left on my m20) but the line is way small.




4) Fuel lines go here I believe (and I have a pic of the lines) but that third whole. Well on the m20 there was a line going to teh charcoal canister (which I don't have on the m52 at the moment). Weird thing is, my charcoal canister already has a line on it, and my engine bay has a line in it. On other e30s there is a line from that fuel line area straight to teh charcoal canister. I seem to have two. WEird.


Here is the end of it.

And the fuel lines


5) Don't know what this is, or what line goes to it. However, I think I found a sensor in the area which fits perfectly.



6) Huge whole on teh top of the alternator confuses me. I assume I leave it as is.


7) This is in a bundle of wires that goes between the fuse box and strut tower.


8) this is the coolant issue I was having.

This thing:


Tehre are two hoses coming out of it, then another hose near it in the engine bay. And one hose going into it. But only 2 holes for the heater core. So don't know what to do here, I heard that I make a loop or something.



So that's all that I could find poking around at the moment. ACtually getting the radiator in and working should come after this stuff I though.

Still need to do power steering (easy) and I got the brakes/clutch working last night. Although my clutch is still mushy but I spent forever bleeding it. It was mushy before I did the swap so I'll figure that out later.

-m52
-obd2 (have an obd2 harness with labels on where to put wires, I stayed obd2 to avoid costs of obd1 parts but maybe I should have listened to everyone ever and gone obd1) I have the DME from the e36 and the whole complete motor+harness from auto car
-getrag 260 (driveline is all hooked up and everything is good to go)


I was kind of hoping someone local woudl be kind enough to swing by and take a looksie. Or compare their swapped car.

1: e36 obd2 air pump scrap it you dont need it if you have the right soft ware that enables you to do so.
2: round plugs are the obd2 sensors both of them post and pre cat (once again odb2 crap) and the middle is reverse lights from the obd2 harness
3: I believe it is the obd2 evap purge cylinder ( you will need this obd2 crap again)
4: the 3 hole is the gas take vent tube, you run a line from that the caster and another line form the canister to the evap valve (#3) and then a line from that to the tb bung for it
5:I believe that is the fuel pressure sensor to the obd2 dme ( once again obd2 emissions crap)though not 100%
6:the hole was for the stock alt cooling duct
7: need to know the coloring of the wire on the plug but most likely air pump power plug
(obd2 emissions crap)
8:that is the coolant heater bypass so when the ac is on it does not allow hot coolant into the heater core (toss it you dont need it) unless you are planning to spend a bunch of time building a adapter to make it work when the ac ( if you are going to install it)

yes you are cheap you should have spent the money on obd1 stuff it is cheaper in the long run and you could be driving your car now rather than asking for help ( not knocking you but its the truth). I my opione for e30 swaps way way way better obd1>obd2
and you should only half to go obd2 if you are running a s54, nv54 or a s85

I hope you have bought soft ware that will allow you to pass all the extra emissions crap ews crap air pump crap and all the extra crap that obd2 has that you dont need or what on you e30
Also who made you adapter and let me see a pic or 2 of it

[87e30]

Thank you for the explanations. I will ditch that A/C crap bypass since I already ditched A/C. Then tehre is just one in and one out, easy.

I didn't purchase software for the swap but the guy I got the harness from said that it would not be difficult and I had everything I needed in the e36 car. I may send him a PM towards this thread and see what he says...

Security key and obd2 code reader are kinda nice if I can get them to work.

[gregslow318i]

so is having a stomp test ware no tool is needed *if their is a problem
and a fuel pump kill switch that is hidden
who made the adapter?

I PM'd the guy that made the harness and hopefully he will chime in. His name is louis, etzxx or something like that is his user name.

He wrote up and labeled where all of the wires go so I'm not as worried about that part as gettting everything else hooked up first. I'm sure I'll have questions on the wiring when I get there.

Don't scrap the air pump, if it was working it's usually worth 75-100 bucks used.

Some one help this guy! He has a razor on top of his car! SOO pimp!!!

Did you save all the EWS stuff from the e36? You'll need the ignition key and sender ring, EWS module, etc...

I say OBD1 swap it.

You will use e30 heater hoses, the valve is from an e36 and I doubt it plugs into the e30 anywhere, but you can try.

Do you have an external fuel pressure regulator? If not, you need one. The OBD2 FPR is located on the frame rail, the fuel rail you have doesn't have one.

Sell the air pump.

I have the ignition, key, ews, etc.

I'll get rid of that coolant valve.

Hmmm... didn't know that I needed a fpr... good info. thanks.

On bimmerforums do people actually buy the air pump?

Yes, they do buy the pump, I needed one for my former e36 and paid 75 or 100 bucks for it, IIRC.

[etxxz]

oook. so, this thread is confusing. what's going on? Me and Clayton here have talked about all he needs OBDII wise for getting the car running.

lets see.
#5 above is not the OBDII FPR. its a gas tank vent to the intake manifold. IIRC it goes to the charcoal canister. It is emissions related so i just bypassed the canister. I mounted the OBDII FPR where the cannister goes so it would be right next to the stock fuel lines.

The OBDII FPR (which itold you to pull form the e36) was/is located under the firewall onthe driver's side of the e36. Just follow the pressure and return lines.

7)looks like an e30 plug?

don't use the coolant thing, just route your hoses correctly to your heater core, or bypass it ; / I beat mine to death into a million pieces to remove it when i stripped the car.

I don't want to get into the obd2><obd1 argument. to each his own. If you can get the obdII stuff with the swap, then it is cheapest, most reliable way to go. There's a good amount of work involved on the OBDI conversion..you are substituting this work for routing 4-5more wires.

[87e30]

Thank you very much for clearing these things up Luis. Hopefully I can get everything up and running. My mistake for not pulling the FPR, I must have spaced and not remembered. I'm sure that you've told me. You've been incredibly helpful.

Out of curiousity, there is a 1999 528i being parted out near me, I assume I could grab an FPR from that car?
