evo specialist in NW/london middx ??

[chevy-stu]

Hello jap chatters, New to this forum but having just bought a Mitsubishi VR4 I need to ask you lovely chaps if anyone knows of a good place to get my new motor servied and checked in In Middx/NWlondon area.
Mechanically pretty similar to the Evo (4wd/anti-yaw/twin turbo etc..) so presumably an evo specialist would be the best bet, rather than a probably woefully inept apprentice at my local Mitsubishi dealer.

Cheers guys, I've heard of Power Engineering, didn't know they were Jap Specialist...
I'll check out Lancer traders bit too.
