Turbo charging the E92 M3.

So I became very good friends with the head mechanic at my local dealership and he's given me countless tips and advice pertaining to the E92 motor. He also does work on the side for MANY E92 M3's. Curious, I asked him what he was working on now. To my surprise, he was working on turbocharging an M3. I asked him how that was possible and he said he was putting a rear mounted turbo on the M3. I asked him countless questions and all of them were sound, EXCEPT programming the ECU. He said that the M3 would adjust accordingly to the turbo. He said he would only run it around 4psi to start with and adjust accordingly. Now with that in mind, I wanted members opinion/concerns/input and if that is feasible.

I wonder if he is basing it around this system. But even then, they need programming.....

turbocharging has ALOT more variables to consider...turbocharging a high compression engine isnt easy....BUT horsepower freaks developed a kit for the E46 M3 and i imagine there will also be a kit for the E90 M3 down the road...lots of R&D is required for a reliable kit

One of the nicest things about the M3 are the ITBs.. Individual throttle bodies give the m3 awsome throttle response. Throttle follows ur foot without delay. Supercharging vs Turbocharging, youll always have boost on demand because its running off the belt so theres little lag. Turbochargers will have a lag depending on the size of the turbo and also location.... A rear mounted turbo charger should have way more lag than a normal turbo....

(why the sigh? is this a much asked question?)

I would be surprised if they didn't at least fit a thicker gasket to drop compression for turbocharging. I can't see a situation where they'd want to leave it as high as it is with the engine in normal form. Other than that I'm not aware of any extra variables over S/Cing a non-FI engine. Both present fuel, space and cooling issues. Both require a remap (most likely).

Not sure of the economics but possibly the economics of S/C are more favourable than Turbo. Also, it's possible that space plays a factor in our specific engine bay.

Nope. rear mounted turbos have specially sized housings to avoid just that problem. They also have the advantage of being naturally cooled which, in most cases, eliminates the need for intercoolers. They replace you rear silencers too so you save a bit of weight there too. All good one it's been designed for the specific car with all required tuning work done. Not sure if there's a big enough market for M3's though?

Because (unless they go with a rear mounted setup) it will be a plumbing nightmare under the hood as well as a tuning nightmare. Look at what it took to get the HPF M3s working - HPF had to hire away one of AEM's top engineers so he could custom design a standalone EMS for their kit.

i spoke with Dan from HPF and he said they didnt plan on a turbo kit since the s65 had an aluminum block and wasnt turbo friendly. dan said in order to make it work properly you'd have to build the bottom end and that aint cheap. so i wouldnt hold my breathe to see if HPF makes a kit

+1 e46 m3 cast iron blocks are amazing and can handle a tremendous amount of power....the e92 m3 have aluminum/magnesium block which will have some real issues handling a turbo set up. Dan expressed the same comcerns with me stating that it's ulimatly just not cost effective. So I agree with Kioken and that's to not hold your breath.

is his name JACQUE?

he scammed tons of e90 people and is a tech in a florida dealership.

His side business is a joke and was the laughing stock of 335i owners. I forgot his company name but its well searched in E90 section.
