91' 318is S52 Swap "The Beast"

Since I bought the OBD1 intake boot with 2 holes on the bottom I was able to put the IAT in one hole. To do this and have it seal well I had to shave off some plastic on the sensor to make it a little more round

I then got the ECU mounted. I had to move the brackets back to the furthest hole possible to allow me to actually plug the ECU in easily.

Brackets bolted up

All done


Worked on getting the harness to fit inside the cover a little more, still have so more work to do on it. The OBD2 diagnostic port won't fit in the hole by the fusebox like I hoped.

Bolted up the throttle cable to better stabilize it

Since my MAF plug was an OBD1 plug due to the P.O.'s big MAF I had to dremel the inside so I could plug it in. Not pretty but it works :)

Also got my KAmotors intake. Not sure if this is how I'm going to mount it, I'm still playing with the setup


Here it is running with the MAF installed. MUCH BETTER!

I've got a single vibrant stealth series and it's loud as hell. I think that will be one of my goals this winter. I need to quiet it down. No emissions here though :)

How about a little resonator somewhere before the vibrant?

What did you end up doing with your throttle cable?

Its routed pretty odd I was hoping to try to find a better way. I'm most likely going to put the mount for it on to stop play in it.

Thank you :)
You know I'm not sure yet. Its going to be quite aggressive.
Thinking maybe just one high flow cat and a muffler.
Maybe not cats and just a resonator and muffler?
I don't know, I was going to start looking into common setups more

Keep us posted :), just make sure you can pass emissions.. I've heard to many stories, lol

Awesome! Congrats on startup

Thanks! It's been a big relief

Congrats! Sounds like a monster! What exhaust you plan to use?

Congrads.. I hope to hear my M52 soon

Thanks!

You'll get there soon!

WOOOOOOOHOOOO! :)

You should get your MAF sorted out first and make sure it's not that first. Usually they will run w/o a MAF plugged in and use a default setting but won't run well. A vacuum leak would run bad at idle but would smooth out if you had it revved up. If you had access to a fuel pressure gauge you could rule that out. Smoke machine for vacuum leaks.
Good luck man!

We tried the s50 MAF (which for some reason plugs right in) and it had no affect

[craiggroves91]

I'm not an expert by any means but I'd definitely drain the gasoline that's been sitting in the gas tank for months and fill it up with fresh stuff before firing it up. Once again this is a shot in the dark but stale gas can form sediments and hypothetically clog up the fuel system. Personally I'd refresh the gas and the fuel filter before starting it up. But don't quote me on that.

you know that might be a good idea, just to rule it out

It was sitting for a long time
