CSL/M5/Porsche hybrid!

[Aaron318iS]

Owner of this CSL has replaced the S54 3.2 with an E39 M5 engine + 6 speed. You can also see Porsche GT2 calipers (I think!) on the front and Porsche seats on the inside...

Why can't people do this to normal M3's though?! Rumor has it the car was shipped to Hartge for the conversion

Those are Porsche GT3 seats - They look fugly to me. Nice engine bay now though

the guy has too much money. doesn't know what to do with it

Actually, when people do stuff like that, do they actually make the car faster?

I mean, yeah, you might be able to push the car faster in a straight road. But what is the trade off regarding to the CG position? What about control and handling? Realibility? Weight penalty? When turning, CG location is very sensitive, by adding more weight to the front, and reducing the weight at the back (i saw the CF boot) you might be making the car more unstable, considering the inherited instability of a front engine car. (Try to consider the moment arm in turning, you will know what i mean)

I believe the engineers in BMW really know what they are doing. For the engine with certain HP installed, the frame can sustain that much HP only. In other words, to make the strucutre as light as possible, the margin of safety should be about 0. Say if you put more weight in a structurally critical component, it will increase the load factor, and by putting a more powerful engine in a car that is not designed to do that, I really find it hard to justify.

Well, anyway... I do understand the joy of modding though.

wow thats amazing...

but yeah not too keen on the seats either

Regarding weight only, the S54 in a standard E46 M3 is 148kg. The S62 is 158kg, so there isn't a huge weight difference.

I wonder if he is using the CSL driveline or if he's swapped in the M5 box and diff etc?

It's certainly a hot car, but it's a bit of a waste butchering a CSL like that.

Thats pretty cool! looks likes a tight fit :P

The CG could even be shifted to the rear, i believe the V8 would be a shorter engine than an inline 6.
Nelson, its a CSL. They had semislicks as an option. If they were made to withstand those forces im sure they can withstand a few more kW. Its a stock bmw engine, im sure it would be quite reliable.

hey U might not like the seats, but I tells ya you love them heaps when you are in the car racing round eastern creek...they grip quite well


But that's a nice conversion, wonder how it drives

Also I wouldn't be surprised if Hartge did the conversion, as they have made a V8 M3 before

[Merli]

All that work and money spent on those brakes and in the end he'll stop slower than a stock CSL

Cookie to the first person to tell me why

[CafeRacer]

semislicks were only an option, and i doubt those wheels are much heavier

is it cause the brakes are the PCCB (Porsche Carbon Ceramic Brakes) and they do not have as much stopping power but they fade much less than normal brakes.

[ct323i]

oh shit thats hot!!!

[Dado]

that's sick, the car has just the right things on it. Nicely done!
