Turbosmart MBC

Just picked one up a few days ago, and all I can say is WOW! I should have done this a long time ago. Right now I am peaking at 11psi and settling back down at 9psi. I don't plan on going any higher than that with any other supporting mods. Still running the stock plugs and don't notice any adverse effects. I have a friend that has a WRX and even before I could race him he had to get a Joe P. MBC because he didn't like the fact that I might be able to beat or at least keep up. I know he had a run in with BlkZoomZoom and he did want to face the fact that another Mazdaspeed could possibly beat him.

Nice! As far as stock plugs go, you most likely won't notice any adverse effects... At least until it's too late. J/K, but it'd be a good idea to consider some coppers down the road.
