95 % of the parts are fabricated, so you cannot buy them online.

Or else you import my XM3 Just joking, would not even sell if someone have paid 250 k USD. This is a "dream Project" for me)

Well, they used to make AWD e46s for some parts for NA, heard it was for places for ice.
Not sure if it was true though...

Yea we have them, they are called xi.. For example the badge says 330xi. But that awd system is not nearly strong enough to handle the power that mert is putting down.

There was never an m3xi

My Ride: M3
While working on E36 M3 Euro TT (RWD M3) we have redesigned the Fuel system of XM3:

Two Aeromotive Pro Series pumps feed 212 lb injectors. We have been on double Pro Series since 2008 but they were not feeding as good as the new connection.

Each Pro Series is now feeding 3 x 212 injectors. So the fuel rail is divided right in the middle.

Two fuel /methanol pressure sensors hooked to Pectel.

212 lb injectors @ 100 psi will be 316 lb. 316 lb = 3318 cc each injector @ 100 psi.

Do I need that big of injectors? Yes.

We needed to increase injector capacity as the fuel is methanol and want to raise boost pressue up to 45-50 psi.




There were two options:

A- buy Moran injectors 300-400-500 cc. they are very expensive compared to Siemens 212 LB injectors.
Methanol kills injectors very often, so I need to keep injector price lower.

B- raise methanol pressure. Chose route B.

Once our religious holiday ends will road test.

New tires arrived from States for XM3 / RWD M3s.



Good news Vbox Video Lite is here but its got a 100 pages long manal....

Re: All Wheel Drive E46 M3

Aren't you limiting yourself considerably by running 300lbs of pressure as opposed to going for 4-500lb moton? Overall though things are looking good. You'll have to go alpha GTR hunting when you're done

I think I could not express myself.

I did not mention coil over spring rates, I wanted to tell about the fuel injector capacity.

Moron Injectors go up to 575 LB each.

Thank you for the nice words.

Yesterday I ve thought about GTRs, M3s.....Although GTR is very new compared to E46 M3 it has undegone a very intensive tuning program.

So many people work on GTRs worldwide.

Enthusiasts in United Kingdom and USA are pushing the limits of GTRs up and up.

I am a member of gtr.co.uk since 2003,and British GTR fans have been improving R32-33 and R34s since 90s.

But only very very very few people work on E46 M3s...........

I was speaking to myself about this yesterday: M3 vs GTR...

GTR has displacement advantage. 3500 cc S54 XM3 vs 4100 cc
GTR makes more power on boost only.
Recent GTRs run on twin 64 mm chargers. 1500 - 1600 whp.

I was on twin 68 mm back in 2009, was too laggy. Will try 62 mm chargers as XM3 now has an auto tranny and lag is not a big issue these days.

XM3 will be using nitrous, I am used to 250 shot, so N20 will help to overcome power differece. GTRs did not get addicted to nitrous yet, why should they?
GTR is very very fast on boost only.

Transmission: XM3 shifts as fast as GTR.

Transmission: GTR has very short gear ratios, XM3's ratios are longer.

All Wheel Drive Control: XM3 has the ability to turn ON / OFF all Wheel drive system
XM3 has the ability to adjust the amount of torque to the front axles.

Weight: XM3 weighs 3400 lbs. GTR weighs 3950 lbs. This is not gutted, stock weight. After gutting XM3 will still weigh 500 lbs lighter than GTR.

GTR has better aerodynamics.

GTR is a very good car for the ones WHO like hardcore power.
I could have purchased a GTR and get it Alpha XYZ,meaning that get the fastest from tüner XYZ. But that would be "pay", "get installed", "drive" and "boast about your car".

Thats not what I like.
I like to work on M3s, plan, produce parts, install, map electronics, test, dyno, road test, re-produce parts, plan continuously.....Been working on S50 B32 since 1997 and I am still in love with S50 B32 (S54 as well). I simply did not want to be one of the other car owners, rather wanted to build unique M3s cause I am in love with four of my M3s

All Wheel Drive M3 was my dream and it came through.
Our time has split into E36 M3 Euro TT and XM3 TT, soon hope to make videos of both M3s.

Re: All Wheel Drive E46 M3

The thought of an and m3 although sacrilegious is totally awesome IMHO and even more so if it's got on off mode. Props on the pursuit

There something beautiful about people who build " flux capacitors " to make their cars travel beyond the norm... It's all about the engineering and experimentation that's makes it all so much fun... Good work at modelling what a enthusiast looks like.. Ur cars blow my mind... Reminds me of the Cold War space race...

Have been working hard on E36 M3 Euro TT for the last 4 months.

Once my E36 M3 Euro TT is dialed in it will cut faster times.

Back to XM3....

Body is completed.








from the front it looks like an E46 M3


Parts from Cosworth Pectel


ICD Dash with 14 analogue and 6 digital inputs ...




Pectel Cosworth NTK WideBandSensor






Pectel Cosworth 3-axis accelerometer. All Wheel Drive means traction, I wanted to be able to measure longitudinal g.

Hope to hit roads in a couple of days.

Started road testing XM3 last wednesday. XM3 grips and grips. It has very fabuluos traction @ 10 Celcius. I turn OFF AWD and welcome the old RWD days, spin and spin in RWD mode

Now, as the AWD is a new World for me, this bustard is lifting off its head @ 60-80 miles under hard acceleration.

We are working on suspension settings to minimize head lift. Got some tricks and will be testing them.

OOps head lift is not cylinder head lift, the two front tires are lifting off the ground. They dont lift off 100 % but you can feel the steering Wheel getting emptier under hard acceleration. During road test an Audi driver asked me what kind of a system I installed to lift the head off He must have liked it



Meanwhile, I am setting launch control in order to launch.

I did not want to risk oem front drive shafts, installed DSS front drive shafts.

DSS front driveshafts are normally direct bolt on, in my case we do machine them to fit into the Limited Slip Differential. Getting the CNC job done takes half a day, they needed to fix the long drive shaft and had to source out adapters etc...

Finally, DSS front drive shafts and front Limted Slip Differential are working well.

LSD settings is another subject, will be playing around ramp angle of the LSD.












Launch control settings are dangerous as too much ignition cut will melt the pistons. Requires careful settings...

Home made all Wheel drive control unit / torque split controller



I ve been working on this device and thank you my GOD it does work.

This is the third generation torque split controller, the unit is installed inside the cabin, enables to transfer from 0 up to 50 % of torque to the front axles.

This device adjusts the amount of torque split at the same time Pectel ECU does control when at which engine speed / road speed / lateral g / throttle position the AWD is turned ON.

So basically my controller and Pectel work in tandem.

Can we name it M3 GODZILLA?

When can we see your creations on a event like Moscow 500 unlimited?
