M30b34 oil pan

[Pontus Q]

I have an e23 m30b34 that is going in my 2800 -71
Will i need to change the oil pan, same as engines from E34?

Anything else that is different from m30b35? Same wiring harness etc?

 

[Pontus Q]

No one?

You will need to use your old coupe oil pan otherwise it won’t clear the subframe. You will also need to modify your oil pump pick up, as I remember use the old front part and mate to the later rear part, you may need to double check this as it was a while ago when I did mine. Sorry can’t help with wiring as went with custom.

actually the B 34 pan will fit its the B35 pan that has the sump in the wrong place

There you go, like I said it pays to double check

Cheers. John

I’m confused... you have a e9 getting an e23 Engine.
Where does the m30b35 come in? Are you using Motronic 1.3?

Thank you for the replies

I have a e9, 2800 -71. I have a donor car that is a 735 -83 equipped with an M30B34 motronic 1,1.

From earlier posts i have come to understand that the M30B35 used in the E34 require a change of oil pan and pickup. My question was if i needed to change oil pan on this engine also.
The second part is a question regarding if there is anything else that is different from the swap to a M30B35 (that there are many threads regarding) or to a M30B34 (with no threads...)

Sorry if i have been unclear

Don can confirm, but I think you can adapt 1.3 Motronic on a B34??? If so, that's the route I would take.
