Nice stuff Jimmy!

How's the adapter plate going? Do you want to try using one of my "old" plates for fitment?

Huh.. Back home from working on the ITB's for 12 hours.

Starting to look really good.

* The new adapter plate is done.

* It's matchported to the head.

* The ITB's has been torn down and got cleaned and inspected. And some machine work has been done to them.

* I made a new throttle axle for 5th and 6th throttles, So now I can move the TPS to that side so it wont hit the VANOS solenoid.

There are some pretty bad edges inside the S50 ITB's to start with. Last thing I did today was to put JB weld inside of them so I can port them tomorrow. It's going to be great.... I hope!

You mean the intake ports? That is some kind of Epoxi that Erland uses.
I would use that for the itb runners if it was easier to get... But now I had JB Weld in the shop and I'm sure it works just fine.

The stuff Erland uses IS hard to get, but it lasts.

If you ground down/cleaned the surface for the JB weld, it may work just fine as well. I think we've both seen JB weld hold up with MX....

Looking forward to pictures!

I really hate match port the flange mounted to the head. I didnt want to hit inside the port with the grinder... But luckely it turned out good.. I took as much as I dared with the grinder and the last with a 80 grit...

Did you use an aluminum or steel type carbide bit?

I used a steel bit to get close, then a fine aluminum bit with a cutting lubricant (green stuff) to do the rest.

It's harder than it looks, that's for sure.

One thing about fuel injectors: There are 2 types, projected tip and non-projected tip. The OEM M54B30 24lb/hr injectors are non-projected, but I think you'll probably need a projected tip for the S50 manifold. Bosch just introduced a "version 3" injector that has really good atomization paterns.

Those are non-projected, it just means the tip is short.

Are you down at the shop?

Finally!

Another 12 hours in shop and the ITB's now fits perfect.

Perfectly match ported, All edges in the runners have been smothen out, The machine work is done. This was so much more work than I first thought.

But now it fits, and hopefully works good. Now I can start working from the ITB's out to the plenum.

I'll post pictures as soon as possible... Now I need 12 hours of sleep.

I agree this is awesome to see more builds like this in e46 world. Even though its somewhat old I haven't been on these forums for a couple months due to the ridiculous number of honda type posts.

As these cars get cheaper I hope to see more of these. How much do m54s go for?

2.5 and 3.0??

I want to start a build myself but cant decide between an m50nv, s50, s52 or m54. I already bought the Non vanos m50 to make a turbo race engine. And i want to go N/A with the s50/2

Very nice my friend. I like your style.

Here comes the "short" story about the ITB's.

I started to work with the an adapter plate. I'm lucky to have access to these:



I started with doing a gasket...



Then I started the machine work.







As you can see, I made it angled to have the injectors to sit in a better angle. But at this point I was pretty disappointed when I saw the sharp radius turn down to the intake port. I didnt like it, and just as I was sitting and looking at it, I found like 10 things more about it that gave me a headache.

This flange had much more work put into it than it looks, But I decided to not use it. Scratching my head for a while and then I did a phone call, and 5 hours later I had this:





I knew of a company near me that has a water jet cutter, And they had a flange cutted out for me... I just gave them a gasket to do some measurements at... I told them to cut for the ports with an 2-3mm margin. I spent a couple of hours getting it to match:









Now Everything fits and match... Now I needed to assembly all the ITB's part that have been cleaned and inspected. My first thoughts when looking at the pile of parts was.... "Hmmm... Where..... How... Maybe if...No... How but... Hmmmm... &%!"!"¤/¤/#%"!!! "

So I decided to sort everything so I could easily see what parts I had, And with some puzzle back and fourth I ended up with this:

















After 6 hours all the pieces have been putted together.



















There will be more pictures with these mounted next weekend.

Great work Jimmy!

With a mill at your shop, you've made really fast progress figuring this stuff out.

I understand exactly what happened with the "angle spacer", I had exactly the same thing happen when I made a wood adapter as a trial piece. But...we're not going to get it right on our first try every time....

How thick is your adapter plate? It looks thicker than the 1/2" stock I was using.

I still have all the ITB pieces from my manifold, I'll ship them over with the next package. (I don't need them)

Very nice pictures, keep it up!
