what did you end up doing for the oil temp and pressure sensors? I only have one sensor (pressure i believe) on filter housing on my S52, trying to figure out what the best option is to get temp sensor (and what part # for sensor). Looking at Rally Road block

I am doing a M52TU Dual VANOS swap into my newly acquired 1987 E30..
Need advice on parts (I have been thru the List)
I bought a E39 for a parts car not sure if I can use everything...
But it came with a ZF box!!!

So if i got the harness with the motor, what work do I need to have done to it for an OBD2 swap? I am just not sure what you had Markert Motorworks do with the harness.

I may have posted this already, but I can't thank you enough for this thread. When I did my swap 2 years ago this was a god send.

Yeah, I'm using it to see what photos I had where. I'd like to not make everyone have to get an add on or extension

I'm going to attempt to take a second and recover pictures. Wish me luck

What are your opinions on the most solid hosters? I can use flickr or the forum itself maybe?

Weird, I thought for sure I ordered the OEM plates for my swap and they worked fine, but it's been a few years

[eternal24k]

Are you using the stick headers, because they do fit those?

I am, but the OEM plates are larger, not even the gaskets fit. The holes are about 1/4" too far out. After researching it more, it appears they are the same size as the Achilles which installs on the tubing, not the head.

I am ordering some Turner ones to fit in the appropriate location.

I will say, for the record (since I did not know) the OEM SAP Delete Plates do NOT fit on the head with the exhaust headers. I just discovered that they are intended to be used on the tubing (but I am trying to eliminate that entirely like done in the OP). Here is a pic of the placement on an S52:
