E30 Touring 3.0L M20 Stoker Build

[E30-TourZing]

Hello Mike!

No, I actually sold my touring on RV3.

I wanted to sell it on BAT as I like the basis, and I am on it frequently, although I didn't have a super organized portfolio of receipts from the restoration and I could not confirm the millage on paper. Just my word. I have seen people get pulled apart based on that alone.

The RS's are from my friend CJ. He left his E30 sedan with me while he is in Mexico for the next few months. he actually organized the last Stromung group buy. I really appreciate having the car with me as its a template at the momement for my own car. His car has 140,000 km's and has not been messed with. That's what I am going for as well, atleast astheticaly.

Thanks again for organizing the group buy. I look forward to installing the Stromung system when my engine is done.

Ahhh, I guess I did see it on R3V at the time. I remember the photos in the for sale ad being excellent, which is probably why I thought I saw it in BaT. :D

You're welcome and thanks for your participation!

All the pictures are absolute porn.
Very excited to see more!

Okay Petar... You win. For others who are interested, these are the Recaro high-backs I mentioned earlier. When you sit in these seats you cant move. I will be changing how low they are though, so the hug from the bolstering won't be so dramatic. The weave under the seat cushion is worn. I plan to replace with cut up seatbelts.

Stay posted in the spring when I update the seat weave and dye the colour of my rear seats to match.

those are awesome

those are awesome

I agree, they were a super rare find. They had E30 seat rails on them as well. I also paid very little money for them.

Question I was hoping to get more traction with...

- What size injectors should I use for my build? I think my realistic goal should be somewhere around 200WHP.

Any input would be great.

Thank you!

this is so awesome.

24 is plenty, gives some room for upgrades to other parts later on

Thank you so much for the reply digger! I have likely gone through 70% or more of your threads before deciding which engine build I was going to commit to.

If you lived closer, I would send you a case of beer.

My plans are still to run a standalone tune, but I have to admit, I am not that interested in playing with a computer next to me. Jim from M/M told me to get a chip made up. He recommends a programmer from Ontario who he has worked with steadily it seems.

Can anyone give me a first hand experience on the performance benefits of megasquirt vs a custom made chip? Will the difference really be that noticeable for the extra $600+ it may cost me?

I am open to both, but I do not have any experience with either really. Future purchase of these options is something I really want to be researched in.

Any advice in relation to a stroked out NA motor would be great!

this compares a custom tune chip with bigger M30 AFM vs a standalone. the standalone tune isnt very good either especially the bottom end as it was a rough first pass with timing curve from a different engine. ditching the crap upstream of the TB is worth power on a modded engine. the engine will be more responsive as you get a proper TPS not the throttle switch this way you can tune the transients better. it also easier to tune for future mods



i recommend starting and running the engine on motronic as you know its going to work well enough and little risk of a shitty tune screwing the engine where as with a standalone without a good base tune more chance for things to go wrong (overfueling, excessive cranking, timing way out)

Sweet car. Reminds me of the touring I had. It’s the only BMW that I wish I had kept since they are so rare in the states. Mine was same color and year. It also had a m20 2.9l stroker. I built it using a 524 td crank, which was a forged crank. It’s been so long I don’t remember all the brands of my internals. It was never on a dyno. The compression was 11/1 when I got done. The rods were super light and forged also. A Schrick cam, upgraded valve springs, retainers, rockers full radius valve job. Good thing I use to work in nascar because the owner and me go back over 30 years. Thanks to him I can do all my machining my self. Only had a engine dyno when I built that motor he now has a chassis dyno. I don’t remember the grind but it sounded like a small block v8 at idle. No one believed it was a inline 6 when they heard it crank and idle, but after they heard me run it to it’s 8k redline it didn’t sound anything like a v8. My pistons were domed slightly. It was faster than a m50 swap car. But being a BMW mechanic for 25+ years I got an idea and it worked awesome. Really added to the performance of the car. It was a good bit quicker after I did this. And was all done with all BMW parts. I had a bad m50 which is the one without vanos. I installed the m50 fuel injection on the m20. I had all the parts laying around. That conversion got me a mass air flow setup instead of the barn door factory m20 one. Also individual coils for each cylinder and I mounted the 2 knock sensors on the side of the block. So I had a much more efficient and better overall fuel injection system. Compared to the stock injection. Also the dme was from a 325 with a custom tune on it. All you need is the harness, dme, fuel injectors, coils you will have to make your on wires. I just used my factory and cut and put ends on them that fit the coils. Just pull the boot off a m50 coil and u can plug a wire into it make a mounting plate for them also u will need the air flow meter. Even something as small as swapping the injectors a adjustable fpr can help a lot. The factory injectors have a poor spray pattern. M50 injectors are a direct replacement for factory and u will see a difference immediately.
Again sweet ride. I have a friend who lives in Texas has a BMW shop but he took a touring he had and put M3 fenders and quarters on it. The quarters started in the rear doors. It looked like it came factory that way. Also has a s54 and pretty much anything u would want to do to a e30. Here’s a picture of it.

Knew it looked familiar. But damn. Was he able to sell it?

E30 Touring 3.0L M20 Stoker *update*

Well Hello again!

Thank you all so much for the input and interest in my build. It was been a lot of fun to connect with fellow E30'ers, as well as very informative.

It has been about a month and a half since I last posted here and a few things have happened on my end. I took a few nights and weekends off working on my project in February as we got some nice snow here, and ski touring was calling my name.

My soul focus for since January was to make a rolling chassis by the end of march. So far this seems to be coming forth.

After removing and painting the rear subframe I continued with the rear undercarriage. I replaced all the hardlines and E-brake lines, and then pulled the rear swap bar to apply some red paint. The sway bar bushings look good enough for me, so I didnt replace them, although I do have new lemforder end links.

I then removed the front subframe and steering rack for some paint and new Z3 rack install.

- Fresh coat of POR 15 chassis black spray paint. $40 a can.....:rippedoff:
- Cleaned up the front swaybar with some new paint too...

- Now that I have the steering rack installed on the subframe, I will measure up the old rack to it and try to get my steering wheel aligned + rough alignment for tie rods.

- Since my car came with the rare euro-spec manual steering, I have decided to modify the existing shaft. As you can see in the picture it is to long, but I will cut it to size and slip in a new collar. Then weld the aluminum up strong and hope for the best... haha anyone else have a better suggestion with what I have? Or should I just but a normal E30 steering connector and get the spacer kit from garagistic?

P1011453 by Jan Willem Wilderom, on Flickr

- While I was painting everything up I decided to go a little overboard and I painted my brake calipers... hahaha I usually would paint them OEM silver, but I decided to go gold. I might regret this, but I am such a bmw stickler about keeping things stock, and I have to keep things as original as can be with my day job, so I thought it would be fun. Any thoughts before I install?

- And then here is my holly grail of recent additions to my car. I have to give soooo much credit towards my friend graham in Vancouver. He sold me his dual adjustable ground control set up that was brand new for a massively discounted price. I could not have bought this suspension without his help and I owe him many kombucha's. (He doesnt drink alcohol)

He also threw me his strut's that were had the new collars welded in place. I got them bead-blasted and the painted them. Here is the before and after....

My 80A polly bushings just arrived, and they were the last piece of the puzzle before I reinstall my under-carage. This weekend I plan to put it all together again. I will take lots of photos and update progress made. I will be sure to take some ride hight photos to. Pretty pumped!!!

[e30RS]

Great update!
