That is a client's vehicle that was built from the ground up for drifting!
Completely gutted including all sound deadening with a fully built Turbo M20 motor, full suspension, 10 point cage(i think, maybe more), standalone EMS, 5spd conversion, big brake kit designed to fit under 15's for drifting.
The car took 3 months to build, I believe, and the paint is custom, based off of the burgundy e36 color.
We can build you one too, but be ready to spend the money. I cant release the price of that particular car or the exact parts used, but I can say it was not cheap at all.
You will see that car at most local drift events.
Also, the blue e36 M3 next to me is making 480RWHP with 10.5 AFR's and almost no timing adjustment since a coupler blew during tuning. expected power with a proper tune is 550RWHP @ 18psi. Then the boost will be turned up to 25-28psi...

I would estimate 650RWHP on pump and 800RWHP on race fuel at full boost.
the motor was also completely built by AutoFAB and the car WILL keep the A/C!
