E46 M3 project

15 posts in this topic

This is not going to be a full on blog just minor updates and notes every once in a while on this new project car!

 

So since acquiring the car I have been pondering what I wanted to do with it.

My original plan was to create a full CSL replica right down to the finest details in every aspect (why buy one for $148,000 when you can make a replica for cheaper??!! Lol) - I might still do this but with some minor twists. I might even turn it into a full fledge racecar ... I Keep changing my mind about it everyday lol!

This however should not stop me from tinkering!!!

I have always maintained that the CSL power is 95% software and 5% airbox with the associated noise being 95% airbox and 5% placebo lol!! So in order to test my theory out I decided to CSL the engine management of the car with genuine sensors and CSL dme and software. All wiring done via crimping and no soldering as per BMW wiring repair instructions or in this case additions to the main factory harness with correct bmw wiring salvaged from a loom I had. I like originality so I used everything factory where I could, right down to the Oetiker clamps : )

MAP sensor

So how does it drive without the airbox???!!! Mind blowing is all I can say. I have proven my hypothesis above.

Might try out the exposed trumpet next .... hmmm decisions ...

Nice project Tom.

I agree

second hand powder coated but never used air balance rail so I didn't have a say in the colour lol! Couldn't be bothered removing the powder coating as it'd have been quite the mission!

Interesting idea Tom lol all the best.On a different scale i will admit is the M3 csl than the up grade i carried out from a stock basic 316ti to a  Msport 325ti compact. Hope you have an interesting experience both mechanically and the electronics involved as I did. Best of luck.

Had an hour to spare over the weekend for a change so decided to do this. Drives like the real thing and sounds even better as I didn't bother to wire up the noise flap controller instead using an aftermarket piece and adjusting the map to account for it.

Given the scarcity and expense of genuine MSS54HP DMEs, I have been doing a few of these HP DME conversions for others recently. Good to see more and more joining the CSL revolution : P

Slight overdue update!

actually not much changed till recently until the clutch started playing up. Couple of correct re-adaptations and resets and it'd be better for a short while then it'd thump away. I knew something mechanical wasn't right with the clutch mechanism, suspected a broken plastic pivot pin. Low and behold it was and a seized flywheel which I didn't plan for!!

Just wanted to show how good SMG is on the clutch. Sorry for the crap photo! But in person next to a new clutch plate it was almost as good as new except for the outer wear from uneven release due to the broken pivot pin. 

Original clutch 177,000km+ never changed! And people don't like smg : P

Been a while ... the car has been occupying a hoist space for almost too long, but it’s nearing the end of the rebuild with almost all new parts installed underneath ...

just waiting for the cert man to return

Perhaps I missed something, did the read subframe get ripped out? Why the rebuild?

Looks like it had rear subframe mounting area cracking repairs.

Yes, but my question was based on the work being far more extensive than necessary for repairing and preventing 'cracks'. Perfection is one thing, overkill is another.

I did look back at previous pages but didn't see any mention, might have missed something.

Very Minor crack in the usual bottom skin left rear and front right mounting point. Secondary skin opened up to check welding on top which was fine.

Reddish Motorsport plate installed plus GTR style triangulation bar for overkill repair and complete bullet proofing for the most powerful S54B32 700hp NA build ( : P ) lol
