Nice!! Are they going to tune/dyno the car for you as well?

Yep, we will do a baseline of the car as is once it's running. Then tune than a dyno after the tune as well.

I will post both. He was in agreement that the merge should be behind the cats, he has seen a few S54s with merge right after the headers and the power loss was pretty great.

Spoke to the guys today they are adding the xpipe in behind the cats :)

Check my thread out too if you want, but I was able to fit all the wiring, and 2 additional sets of relay wiring I added along with wideband O2 wiring in my grommet. Just soap it up!

Here's my pic of the wiring which is going back in.....

Thanks, I have been following your thread, its awesome.

, 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.

Merging right behind the headers leaves torque on the table due to exhaust harmonics. Also, I'm pretty sure the stock s54 mid section merged fairly far back as well if I'm not mistaken.

You are correct on both counts. There are a few people that merged to early with adverse effects.

interesting. Makes sense

Why not right after the headers? Not entirely sure why you're adding a merge, but if its for sound reasons the closest to the headers is where I've read/heard its most effective at numbing the rasp. Totally only limited to keyboard wisdom here, so feel free to tell me otherwise.

Stoked to see so much progress being made on this build too

That's the Magnaflow unit, correct? I'd be cautious of putting it right after the headers.

It may be best here: I'm sure others will chime in

It is, and the spot you circled is where I was thinking of putting it.

I was thinking of adding this.

I am so jelly, this thing is looking great. You're going to really want to merge that exhaust IMO.

Were those headers from a group buy? They look great!

I was thinking about that, I may get one anyway.

Yea I got those on a group buy, it was actually one that was screwed up because they had major delays so the people like me who waited a really long time got them super cheap. That was great for me because I didn't really need them in a hurry so I got a great deal.

My E38 was having a slumber party with the E30, need to do a suspension refresh on that car.

Finally a lot of updates, I think its a few more weeks before we are running!

Upper and lower rod bearings done, new all besian vanos done, all new gaskets and seals done, new clutch and flywheel. Rod bearings were not too bad two looked like they had some wear, this engine had the recall done on it.


She's in!! Still, a lot of work to do though.


You can see the booster is in, I used the E90 booster and master we will have to see it will be tight. I have an E60 reservoir, and we extended the brake lines over to the master since they were on the other side. Mounted the power steering reservoir it's a little low but it will be easily reachable even with the manifold.

A/C lines are run, and I used the E30 M3 overflow tank mounted where the battery area is.




Pedals are in, need to clean up the wiring.


Used the E30 Oil Cooler, put a new one in. The Z3 radiator is close but it will fit with massaging, I am using the E46 A/C compressor so it's really close. I will need to shave the water pump nut.


Power steering is connected, we actually were able to use the E36 power steering line cooler and bolted right up, its so clean looking! That was Alex's idea at Performance Eurowerks




On to the exhaust. Status Gruppe Headers, N54 Headers and an E36 M3 exhaust. I didnt do the crossover, may still do that down the road, we will see about the sound and what the dyno looks like. We used E46 hangers for the exhaust. The new tips will be welded on to kick out a bit so it will be centered







Used the E30 trans mount with E46 bushings, it was modified using Garagistics kit.



That's all for now :)
