Can't wait for ya! Definitely one of my favorite threads - will be coming back lots in the future when I finally get around to swapping mine.

This car is going to be awesome!!!

Went thru the entire thread, this things going to be a beast when your done man. Question, did you buy a new firewall grommet or did you rob the one off your original M20 harness? Were you able to stretch it over the ECU harness plug? I'll need to do mine this weekend.

Also on the e90/ e83 boosters.. Do they have four mounting studs like a stock e30 booster? I bought a brand new 944 booster for my swap but I'm still kinda interested in learning more about these e90 booster swaps going on.

I still have the M20 grommet, havent tried to fit that over the S54 harness yet. Hopefully it will work with massaging.

The E90 booster only has 2 mounting studs, but thats all it needs, it fits in there very tight. I put a sealant over the other two holes.

Nice good luck! Btw I have found more coding to get cruise control to work if your DME was initially programmed with SMG settings, because the clutch and Gear Position Sensor need to be coded out, and I can help with coding if needed, I would just ned a partial read of the DME which I could send back your way. I hope to add the GPS code location tonight to my thread and the Cruise Control thread in the S54 subsection.

Thanks, I think that will have to be done after the fact, I need to buy the control module, and then Alex has my DME, (its a non SMG DME) which he is programming as well as tuning for my exhaust/intake setup.

i decided to go with the E90 booster even though the lines are on the wrong side. Besides the fact that is slightly smaller, the threads on the E83 booster doesn't line up so I would have to drill new holes. That answers that question.

Car was loaded up to go to my buddy's shop he is going to help me with the heavy stuff.
By for now, hopefully, by the end of the month, I will have running S54!!

I threw this in another thread, but figured for the people looking here, its the most recent on my booster delimna.

Here are pictures of both, the E90 booster is slightly smaller, hard to get a measurement exactly but its definitely slimmer at the bottom, but the E83 booster tapers to the same size as the E90 booster after the first few inches.

The cleeve basically lines up exactly the same between the two, but the E83 booster is about an inch longer than the E90 one, but the E83 master is shorter than the E90 so its total length is shorter.

I am thinking if the E90 works the E83 should work but it may be just a tiny bit tighter, if the engine is back further on the firewall.

Pros of the E83 is the lines are on the correct side and you will not have to extend them around, you will have to adapt the brake lines though since the input on the MC is larger than the E30s.

In the pics I have the E60 reservoir on the E83 master, it fits and sits flat, both the E83 and E90 reservoir are both angled since they go into their cars on an angle.

Im going to try the E83 one first, if that doesnt work go over to the E90.

Hood is back on, I still need to adjust it, but I decided not since it will have to come back off for the swap. I just wanted it on for transport. Crazy to think that the main part of this journey will come to an end soon and I can drive it again!

Rockers came out great! I need to do this to mine. Hopefully you just got me motivated to finish mine

Thanks! I want the car to feel at least presentable until I get the repaint. Especially after the engine is in.

Finished the exhaust and the rockers. I think it came out pretty good, definitely looks a lot better then the half faded white that didn't match.

Final Product





If it stops raining I will wash and maybe detail the outside. Putting the hood on tomorrow, then on Friday its off to the shop to work on putting in the S54. Getting close!

Would you mind sharing what paint you will be using for the rockers? I need to tackle this as well. Thanks in advance.

I am using Wurth Flexible Trim Paint

I used it on my front lip, its not textured but looks pretty oem.

Prepped for a little painting tonight. I decided to go back to the OEM black on the bottom for a few reasons. The PO painted it white, the white didnt match, and it was starting to fade through anyway.

Second reason is there was light surface rust, I sanded that off, looked fine underneath so I need to repaint.

Next year the whole car is getting blasted and repainted and the MTech II kit will be added so I am not too worried how it comes out, just want it better then it is now, doesn't have to be perfect.

Its late so I will paint it tomorrow after work.


Im also going to paint the E36 M3 exhaust that I am using. Just a low gloss black to make it look new again next to the new tips.
