E30 M3 Track Car build
 
I recently purchased a rolling shell and am planning on doing a rebuild to get the car back to track car status. It was previously a DTM replica running an S54 CSL engine.

This is what is use to look like:

Unfortunately the wheels, brakes and driveline did not come with the rolling shell.

Ive been toying with the idea of building the car with all carbon fibre body panels - ive found a supplier that makes the parts at a reasonable cost:

Should be a great project. What driveline are you planning to use?

I already have a rebuilt S54 which is being mated to a e36 M3 5 speed box. Im also using a 3.64 medium case 3 clutch LSD diff. Rear axle is from a Z3 M.

This ought to be good! Looking forward to watching this, so keep the updates flowing. Are you sticking with the rear wing, or will you be going with something more period-correct for the E30/DTM?

The rear wing has been changed - ive gone for a carbon replica e30 M3 Evo boot spoiler and DTM gurney flap

Very cool project. Shame the wheels didn't come with it, will you use center-lock wheels with whatever you replace them with?

Looking forward to seeing updates.

Re: E30 M3 Track Car build
 
Its been slow progress up to now - car has been stripped back to the shell largely - new engine mounts are being made - off the shelf items were not used as the engine was pushed back 60mm (with the help of fire wall modifications).

There are several benefits to this. Better weight distribution and no modications were needed to the s54 sump in order to clear the sub frame.

In the meantime Ive managed to order and collect all the other parts I will need for this build. Engine bay is looking terrible but is being prepared so it can be smoothened out a bit to look pretty.

Here are the mock up engine mounts in preparation for proper mounts to be made by an engineer

So my car builder decided to send me some pictures of my car with one of his carbon bumpers - have to say very tempting and it is only a few kg ! Amazingly the guy does all E30 M3 exterior body panels in sight carbon !

The bay is slowly coming along. Wheel wells finally looking respectable - previous owner had them raised by an 20mm/inch but the finish didnt look so good.

Yes, this is 'The Gorilla's' old car but I bought it as a rolling shell so am putting it together again but to my spec.

So I had some used carbon Ferrari Challenge seats from a 360 which were looking a bit worn so got them recovered. They only weight a touch over 5kg each with side mounts :D

Engine bay is coming along and is almost ready for primer. Spencer has been welding up some of the holes. Hes doing a great job and very particular - instead of just sheet metal he been using the original panels so they match up:

http://imageshack.com/a/img661/396/2euDuT.jpg

Probably not the most cost effective method but I decided to got the s54 manifolds ceramic coated by Zircotec to help manage under bonnet temps - they came out nice. I used this coating on my 650hp Mitsi Evo to great effect:

Spencer from BMP Conversions was able to do the final spray on the engine bay today. The purists probably wouldnt like this build given that we are hacking up a M3 but at least I used a BMW paint code : )

Im very pleased with the end result

Happy to discuss over PM as I have an itemised tracking of all costs but costs have snowballed. Im now at the cost of a standard reasonable condition E30 M3 - there is not much more build left so that is the comparision.

I wanted a track car and that is what I have got using some very good bits. At the moment I wouldnt recover the costs if sold but as they say "If you want to play, you gotta pay".

The shell I got had some very good bits and had a lot of DTM inspired work done to it - raised front wheel wells, wider front fenders, Group A coilovers, Z3M rear end, full FIA cage, carbon panels, poly carb windows, carbon seats, heated front screen, foam cell fuel tank relocated to the boot, carbon diffuser, full front carbon undertray, revised rear turrets etc... If I started from a standard shell I think you would run up in to twice the cost of the standard e30 M3 by now.

The engine conversion aspect was suprisingly straight forward and cheap considering.
