Anybody trying a E46 323??? Is the engine the same as the M50 2.5? I am sure the chassis is even better than a E36 so maybe it can overcome the extra weight in "unrestricted" form???

The motor is similiar...it's actually the M52TU (technical update). Uses a different intake manifold, a semi-drive-by-wire throttle, a double VANOS system and OBDII electronics (probably making Motec a necessity), as well as other internal changes to the pistons, etc.
I've heard of at least 4 cars under construction.

We are building two E-46 323i for ITS next season. We are still early in the build - hoping to be ready for April. Give us a call if you want to share some information.

the e46's just got tagged with restrictor plates too...april fastrack.
That was a mistake in the CRB notes due to a miscommunication between the ITAC and the CRB... You should see a correction in an upcoming Fastrack...Quote:

The car was classified using the ITACs current classification process, so we feel it's correctly classified without the restrictor...

The CRB would like to advise the IT
community that the restrictor specified
for the 2000 BMW 323 was in error. The
advisory committee feels that the 323 is
heavier than the 325 and feels that the
323 is competitive without the restrictor.

What about the 1999 323 that everyone is building? http://ITForum.ImprovedTouring.com/smile.gif
The error happened when the 2000 was added to the spec line of the 1999... Take care of one, it takes care of both... http://ITForum.ImprovedTouring.com/wink.gifQuote:

Darin is a good guy!
Still wondering what people will do to overcome the drive by wire setup??? I know SPEED WC guys convert to old M50 throttle body... Any word?

To sum it up: time consuming and difficult
We originally thought we would be done by April but it appears this will be a research and development year.

Good luck with that project!Quote:

For the little guy it is going to be too costly..... The research I have done indicates the only way to make the OBD II engine (M52TU) put out HP is with MoTeC... The chassis is better and will cost no more than the e36 to prep but the 7-10 k extra worth of MoTeC and tuning alone puts it out of my budget. I hope James Clay, Chet, Ed or one of the other big team guys put one on the track, they just look cool as hell and with double vanos and better chassis they WILL dominate once developed.... until SCCA catches on http://ITForum.ImprovedTouring.com/smile.gif

You may want to look at the Autronic SM4. It has support for Double VANOS and I think it has support for drive by wire. I know Bob Stretch was using the Autronic's system last year in his World Challenge E46. Not sure about this year do to SCCA Pro mandating Motec.Quote:

The 1999 323i does not have a drive by wire throttle.
Autronic is a MoTeC knockoff ( former MoTeC people I think ) good stuff I am sure, but not much less $$ vs. MoTeC.... Still adds big $$$ to an already $$$ IT car.... Can you say north of $50k for a IT car !
