This thread is based around making my adapter plate. It's even got links to the starting plans for the CAD stuff (it's not right though...just the beginning)...it's just cool to play with the 3D image :D.

Just thought I'd share this, because I think it's farkin cool! This is the latest CAD image of the TB adapter plate. So much thanks goes to my friend for doing this work.
First, download the viewer here: http://south-apac.autodesk.com/adsk/...326&id=4639382
Then, click here: http://www.bmwclubqld.asn.au/_privat...TBAssembly.dwf
Click the little planet icon in the viewer tool bar to rotate and spin the image. Then, right click and choose "select" to pick what component to (right click again) "hide", "Isolate" or make "transparent". Then click the little planet icon again to move it around.Comment

Very impressive! Keep up the work!Originally posted by Drew325is
I was reading the EuroCCA thread and there was mention of oval vs round on the head side. What model and year are your TB's from? Does anyone know of a good source for these? I've been looking on UK Ebay but nothings popped up....-Alex Shiroma

Ovel=M3/E36 evo. M50 varent motors. Good luck trying to find a set. They are rare and you are going to pay a premium. Even wrecking yards wont sell them.

Looks very interesting. I've been toying with idea myself for my M52. What are you planning on doing for DME programming? I saw a site in Europe that advertised ITB's, they also strongly recommend there programming update.
Power gains seem impressive, but the throttle response must be awesome. Having driven cars with ITB's before, I can relate.Comment

For those chasing the E36 M3 ITBs, ebay in the UK seems to be the way to go. Within a week or two of each other, two sets were sold on ebay (one set being to me).
As for tuning, I plan on running an aftermarket injection set up. This also gets around the OBD2 issues with the M52.Comment

Here's the lastest CAD image http://www.bmwclubqld.asn.au/_privat...Assembly-2.dwf
When I finally got the engine and TBs in the same place, it became apparent that the TBs will fowl on the head itself. So I've gotten Ian to add the head into the CAD design so work work around this.
So far so good, but I'm hoping Ian can make some changes to get rid of the steep angle of the ports (in the adapter plate) into the head. I think this would be a bit of a performance issue. I'll let you know what he comes up with.Comment

so will u be using an alpha-N type fuel control or will u still use the MAF?
everything ive seen about using itbs suggests that u have to use alpha-N fuel metering which only uses engine speed and throttle position data to meter fuel, is there a way of still using a MAF or AFM?

If I ever get time to work on this again, I'll probably run a hybrid alpha n. So the ECU will use MAP when the MAP signal is clean, and alpha n when the MAP flakes out. Alpha N isn't really bad like many people think...factory ECUs spend a reasonable amount of time on acceleration enrichment anyway (depending on how you drive), which is basically alpha n. At the end of the day it just comes back to spending the time to get a good tune.Comment
