E30 M3 + S50B30

[taper]

Now I'm trying to finishing the wiring

[yetti24]

take lots of pictures and put any problems on here it is very handy to anyone else who is building one , i found lots of info on here , good luck with the project

Pic of today

[appletree]

Nice work, not short of engine hoists i see

Nice work, not short of engine hoists i see

Sorry, but I don't understand you

[taper]

I added a lot of information on each pic to take the correct conection more easy


Where is the correct place to conect this plugs?

Blue circle:

3
5


Red circle:

6
7


and 1, 2, 4???

[penton08]

from what i can remember all of the positives go to the main battery clamp (blue), except the power for the ecu. that goes on the smaller isolated terminal (red).

[yetti24]

as above is correct , make sure you earth the black wire (number 4 ) the best place is on the front suspension turret or bonnet closing bracket , otherwise the car will not fire

[taper]

what do you think if I bolt the wire number 4 to the green circle nut?

[penton08]

that would be fine! thats where mine is.

[yetti24]

that would be fine , i attached mine to the bonnet close bracket , because it was easier but that is a better position

[taper]

Many thanks!


And where is the correct location to connect the plugs 1 and 2?

what do you think if I bolt the wire number 4 to the green circle nut?

Peel back some of the black insulation on 'wire number 4', you may well find its red underneath and therefore its live - you dont really want to attach that to an earth point.

Sorry, but I don't understand you

In the first pic on the left theres two engine hoists, most people have to hire one when they do a engine swop or borrow one from work and youve got two!

[taper]

One is of a friend and the other is from a workshop


My method

[taper]

This is the conector of the car, with all the original pins become with the car




and this is the engine conector with teorically all the pins necessary to start the engine




What I do with the rest of the pins of the s50 engine?


Is this conection chart correct?

E36----E30

8-------12
11-----20
12-----4
13-----13
14-----14
15-----15
18-----18
19-----11
20-----9
21-----7
23-----5
24-----8
25---1

[taper]

All of this conections are Ok?




Can I cut this positive wire from the insulated?




I retired the insultated and the wires are brown, I'm supose are ground.





What I do with this plugs? Cut the wires?



This ground wire is necessary? Is original from S14 engine, and was bolted on screw where is now the black wire.

[taper]

Anybody can help me?

[Jhonno]

You can cut that positive out yes

[Jhonno]

You should have a ground wire from the cam cover to the back of the head

[Jhonno]

Is that the e36 engine plug?

[taper]

Is that the e36 engine plug?

Yes

[taper]

You can cut that positive out yes

From the green arrow, I'm right?

[Jhonno]

Is that the e36 engine plug?

Yes

You need an e30 one... And the correct wiring diagrams to make it plug and play..

[Jhonno]

You can cut that positive out yes

From the green arrow, I'm right?

Yeah, make sure it is properly insulated after!!

[taper]

Is that the e36 engine plug?

Yes

You need an e30 one... And the correct wiring diagrams to make it plug and play..

Now I still done the connections from the e36 plugs to the e30 plugs, but the rest of pins, appears in the pic, of the e36 they not used

[Jhonno]

you can cut the wires out the loom then..

[taper]

The wires from S50 engine that I not use in this swap:

2, 4, 5, 6 7, 9, 16, 17, 22

[taper]

New wheels for my M3













Front 8" rear 9"

[taper]

Today I try to start the engine, 3 years since I make the swap, and this is the result

Maybe the starter motor?

maybe seized up, doesn't sound good. can you spin engine by hand?

[taper]

When I change the bearing rods I can spin the engine by hand.

Today I try to spin it another time

[Jhonno]

The timing is ok?

I can't hear the video.. Maybe a problem with the starter?

[taper]

Timing is ok, the problem is the battery, I think.

[Jhonno]

Fingers crossed for you!!
