E46 LS7 Endurance racing car

Recommended Posts

Hi all, 

Im currently building an E46 to race in the North Island endurance series and thought it may be a good idea to document it here. 
My plan is to build a 'replica' of a WTCC car I had a few years ago but with the engine, gearbox and brakes from a V8 Super Tourer creating an unholy love child of two of my old race cars. 

I'm hoping to have the car weighing around 1,200KG and putting down about 650HP - for reference a standard Super Tourer is around 1,440KG and 550HP.  

Below are a few pictures of both my WTCC car and Super Tourer as well as a rendering of what the final car could look like (Excuse the poor quality).

I bought a 318i and started to strip the interior, remove sound deadening and prepare it to go to Paul (the car builder) to begin the cassis prep and cage.

Once the car got to Paul's place he started to really tear into it and cut out every inch of sheet metal that we don't need as well as prepare the car for air  jacks, fuel cell and cage.

The car came back from the cage builder a few days ago and is looking great. I still had the FIA Homologation papers from my WTCC car so managed to replicate the cage exactly (we added in some rear subframe bracing due to the HP/TQ we will be running and the fact that this is a weak point in the E46). We also managed to test fit the seat, pedal box, carbon dash and steering column - I'm 6'2" and should be sitting in line with the B pillar.

We're going to run the same wide body and splitter as the WTCC car as well as centre lock hubs and 270 slicks so Paul hung the fender on the car and test fitted a wheel he had lying around with spacers to emulate the centre lock adaptors - It looks like it should be a perfect fit once we align the car and add some camber. Paul also started to fabricate some of the carbon panels we are going to be using starting with the roof. In other news I managed to pick up a 6 speed sequential Quaife gearbox as well as a M3 subframe and diff which is currently being built by Kayne Barrie Motorsport.

What a great build!

 

Why did you go four door, and not a coupe?

Thanks for that.

And I guess the weight difference is minor?

The sedans are a little lighter my WTCC car was around 1080KG from memory

Little bit of progress made recently - Paul has had the car up on the rotisserie and has stripped the underside, the rear guards have been 'radiused' to accept the wide body rear fenders and the air jack mounts have been installed. Next on the list is to mount the fuel cell, engine and gearbox before painting the floor.

Hi Richard,
