If you look at the CAD drawing I posted. I will have 3 different sets CNC'd.. Each set will be in different lenghts, 40mm, 50mm and 60mm..
They will be fitted with Wiggins clamps to a BIG, above 20 litres, CF plenum. So it will be easy to test each different length in the dyno.

Finding the perfect runners length can be both a torque and hp win.. And maybe we can find a setup that gives peak HP "as low as possible".
Revving 8500rpm is stressfull for an engine like this one.

With the 12.0 to 1 CR and that intake, the ECM mapping is really going to make or break this build. I hope you provide much detail.
When my engine gets tired I hope to do this on mine. Naturally aspirated is the way to go for a daily driver and bottles are for babies!

Today I decided to move the car from the parking lot to the shop, wich is a 2-3km drive from the parking lot. But this was not as easy as I first thought.

It actually looks pretty funny...









At this point I was so cold that I could'nt even feel my feets from walking around in the snow around the car. So I decided to go in for changing to some better shoes and put some more clothes on... Then back out diggin!

And underneeth all the snow... This is what I found...





As you can see, all the snow that was on the car is now around the car...
And since I'm living in an appartment I dont have any advanced tools like a snow shovel.. So I went to the neighbors living in a house across the street asking them if I could borrow one of their showels.

15 minutes later....



Now I was able to get it out on street... But as everything else today, This was not as easy that I had imagine... 225-45/18" GoodYear Eagle F1 tires does not work very good in the snow as I thought... Just to have the car to move forward in 1st gear without touching the throttle was hard..

But after about 15 minutes I reached my first destination... The car wash, wich is about 0,5km from where I started.





About 30 minutes later the car was clean enough to continue my ~2km long drive to the shop.





Cruising around in 1st gear at idle speed for additional 40 minutes, I got to the shop... By this time it had started to get dark outside...







And after the last picture was taken the camera told me to change battery..
I finally had the car parked in the shop.

That's all for today.

LOL...that's actually pretty funny.

My 4wd truck is in the shop, so snow is not so fun anymore.

Today I got ALOT of work done on the ITB project.

Maybe everything can be done by the end of tomorrow.

Just as it's been told before, There are tons of issues fitting these to a M54. And it's nothing I would recommend anyone to do. There are much easier ways to get ITB's on a M54 than using these.

I've got alot of pictures to post on this but I decided to wait until everything is done and HOPEFULLY fits.

I'm just throwing this out there:

Have you ever considered doing these modifications to a 2.8l motor instead of a 3.0l? With the harmonics issues of the 3.0l combination, maybe a 2.8l might be the way to go as you can really get a reliable engine that can rev above 7000 rpm for long periods of time.

I'm actually doing that with my b28. I'm SC'd, so I'm going to keep the 2.8 crank so that I can rev to 7600 to make more boost instead of stroking it with the S52 crank. Less torque, more HP

Hopefully the ATI harmonic damper will help me with the issues you mention.

I actually got a pretty cool ídea that I will look more into when I got some time left... Whenever that'll be.

Hi,

First of all, I wish all of you a Happy New Year!!!

The work of fitting the ITB's takes alot more time than I first thought. I've been getting new ideas a couple of times along the road.
There is also a big problem to get material these days... Almost every store here is closed for xmas and new year.

I've done alot of work rebuilding my S50 oilfilterhousing, Alot of work was done in the lathe and mill for being able to use it with an external oilfilter. But it showed up that it was all for nothing. Welding in the OEM cast aluminum housing was not as easy as I first thought. I'm sure it would work, But is not as good looking as I first imagined. So I decided to order the billet alternetive from VAC Motorsports instead. The reason for me wanted to use the S50 housing is the oil cooler thermostat.. It would be nice to have when there is "normal driving" going on on the street..

I've also been thinking alot of how to start a project like this "the right way". I changed my plans many times during this build. I could have saved alot of time and money by planning a bit more before started. Next time doing something like this, I will ask myself these questions:

HP goal?

RPMs? I've done some reading that tells about most engines put up most power with an avarage piston speed of 25 meter/sec... And thats ~8500rpm on a M54B30.

Then getting camshafts that are working in that RPM range.

I think that would be something to start with, and that these simple questions could actually save both time and money. The answers you get from this will help you with a lot of decisions further down the road.

Tomorrow I'll continue the work on the adapter plate between the ITB's and the M54 head.

Regards,

I forgot the camera at the shop today, But the adapter plate for the ITB's is almost "done". I will put down some more work to it later but now I feel a bit stressed.

As I mentioned before, This work takes alot of more time that I first thought.

And I also sold my stock head, But I want as much as possible to be intact while working with the ITB's, So I wont get into any clearence issues later. I hope that I can start working on the plenum next Wednesday when I get home from work.

When I'm done with everything that has to do with the intake system, I'll start getting the engine out of the car.
