M3 Engine Modifications!!!!

Barry Chuckle · 08-22-2008, 05:23 PM

Although the M3 is very fast does anyone know of any engine modifications that are availible yet? Now a turbo would make the car shockingly fast!!!!!

Turbos would blow this high revving, high compression engine within 20 kmi without significant bottom end mods!!

If you want forced induction, buy a 911TT, GT-R, or EvoX.

Or buy an F10 550i or E90 335i if you need a BMW

Patience? This topic is like deja vu from the E46 M3 days. You will be up to your ******** in forced induction soon enough.

You will gain another 20hp by removing the air filter.

You mean the charkel filters? The same on that are in the M5 and M6?

spectrumphoto · 08-23-2008, 03:13 AM

Just waiting for the Flux Capacitor to be released... Turbos are for wimps!!

Barry Chuckle · 08-23-2008, 08:34 AM

Is that right, just by changing the air filter I'll gain an extra 20bhp?????

Just put some sort of performance decal on it. That should net you 5hp at the wheels.

Depend on decal origin. Euro or US?

icemang17 · 08-23-2008, 12:27 PM

Yes turbos do increase power.....BUT the M3 motor does not lend itself to boost in stock form...the compression ratio is just too high to add boost too without race gas (even with it really)...so you will need to change the pistons to something lower to really get some silly HP out of one...BUT if that was done.....800hp would be easy...

positiveions · 08-23-2008, 01:17 PM

Keep it stock, and enjoy the car. Remember, it is not the car that makes the driver, it is the driver that makes the car.
Where do you want to be?

Barry Chuckle · 08-24-2008, 11:41 AM

Okay so turbos not a good idea, but what about chipping the engine management system?

You can do exhaust, intake, pulleys!
and soon enough, there will be good software upgrades and those should give a bit of power too!

You know, there's an entire forum here dedicated to answering this question...

People said the same thing about the E46 M3... it will happen for sure. You will probably only be able to run up to 8psi or so, similar to the E46. Its all in the tuning...

Sales@Evolve · 09-01-2008, 04:02 PM

The M3 responds very well to just the basic tuning like metal CATS, exhaust, intake and well developed ECU remap.
There are already claims and what I believe to be genuine dyno graphs which show 460+bhp.
In the real sense, that's what most sc'd E46's make if they want to stay reliable.

The E46 never responded that well. 15bhp from an ECU tune was the max in the real world. Intake modifications never worked unless you were looking at larger intake volume based plenums and exhausts added around 5-7bhp on a good day.

I am sure we'll get loads of compressor kits for the new M3 but I won't be offering them without plenty of durability testing.

It's easy to get big power but for how long?

I'd like to see (and hear) the V8 engine with cams

It already has high performance cams... there is not much to be gained there, if anything.

Patricius · 09-01-2008, 11:15 PM

I don't think we'll find out until aftermarket cams are available. The e46 cams were rather aggressive IIRC, but still a little room for improvement. I cease to believe the V8 is as high strung as the I6, from the way it feels and sounds, to the way it acts, and the way it responds to bolt ons.
