Why don't any M3's run Turbos?

Just a thought....haven't seen one yet.

right now the issue is packaging; in time it will be done though

[DLSJ5]

It's coming.

Because engine goes ka-boom, coincidentally HPF is now defunct too..lol

what? HPF is also out of business for other reasons as far as I know

You've posted something I've been thinking about lately as well. We know about the guy from the Africa turbo post, and that guy dropped off the face of the earth. Everyone says TT require too much space, but my thought has always been, why not go with a single?

And when talking about tuning, I've always thought Benvo would be up to the task.

I think it all comes down to packaging and cost. Because of the space constraints you basically would have 2 options.... do a rear mounted kit and use the stock headers (rear mounted kits have their downsides, ie. poor response, an oil scavenge pump would be needed, etc), or you can go with a conventional setup which would require you to do ditch the stock headers and use new exhaust manifolds.......and that only means one thing........a high dollar kit. I'm not sure if there's enough of an interest or incentive now for a company to do all that R&D.

It IS coming. Just don't expect a kit.

Do you guys remember the 'turbonator' from back in the day?

Single turbo would be quite a task piping wise. Unless you just want to turbo one bank

You might need an external control unit/bypass to make it work perfect, similar to what the harrop blower will be running. Obviously the mss6x has no boost/waste gate control.

The issue with turbos on this car is that the MSS6x family is not designed for boost unlike the MSD8x family. I think the biggest tuning issue would be controlling the onset of boost given its not a linear relationship of X boost at Y RPM in the case of a supercharger.

packaging is def the issue due to the tight engine bay. Don't know what you mean about external control as the turbo boost with be controlled via wastegate off the manifold (fine tuned via boost controller). While it will still be cool I could see a twin turbo setup being utilized first due to running separate manifolds and not using a crossover pipe. I would LOVE to see a top mount, right where the airbox is. It would be a mess of piping underneath but seesm like a good spot for a big turbo.

Tuning def seems to be a hurdle, and of course these things being 12.xx compression are def not boost friendly, but they seem to take SCing pretty well. The tuning of the turbo is much more complex as with an SC having a linear curve it's quite easy to get to run right. I think something needs to be done to the stock DME (ala Maximum PSi e46 kit) or an add on - piggy back controller. Pectal is a nice choice of ECU but reall $$.

Mike you should get on this

Yeah.. packaging and compression are big issues. The M3 has a very high compression ratio. If you add turbo to that, your compression will be through the roof and you'll have a very blown motor. The only way I see it working is if you rebuild the motor for lower compression so then you can add boost to it. Also, the block is aluminum so it can't handle high pressures well, you'd have to sleeve and reinforce the block with iron.

The costs and difficulties involved is simply not worth it. You are much better off buying a car with turbo from the factory than trying to add it to a engine that is not built for boost.

I was approached... There is most certainly a kit coming.

If this were the case, no one would be running a supercharger on a stock motor.

Then we are talking about different cars. The one i know needed a lot of fabrication around the engine in order to be able to fit a relatively big snail there.

Turbo's make it harder for the internals. That's true, but AA Level 3 SC pushes ~9 psi to the internal. Now i know that's 9 psi at top end not mid range, but i think 6 psi from turbo would work flawlesly with stock CR. ///Matthew's car will tell us how far the stock internals can go with boost from something other than a centrifugal supercharger.

[CSL_E36]

With all the work and development needed to make such a kit, I ASSume it would be more financially sound to just do a S63B44TU swap. The current gen hardware/software I would think could make the swap almost plug and play.

I originally posted this cause I dont feel that 500 wheel HP isnt worth 8k for a supercharger setup, so a turbo would be what I wanted. I'll wait and see if anything comes of this.
