Alright, I've gone through the thread and kind of compiled the requests here. This kinda is what we have interest in so far along with the number of people interested after it.

rear disc conversion - 1
rear beam bushing - 1
big front brakes - 1
engine mounts - 1
camshafts - 3
cam timing pulley - 3
throttle body spacer - 1
large bore throttle body - 1
turbocharger adapter plate - 1

I've omitted things that really aren't group buy friendly like an exhaust system which would require fixturing to make and is easier and cheaper to just to go a local exhaust place. I've also omitted things like the sway bars which are already available from some company. So, if you don't see your idea up there that is probably why. I did omit intake manifold because I believe our current one is superior to anything you'd have made for any reasonable amount of money. The dual runner manifold is really quite a nice piece.

I also added the turbocharger adapter plate because I think it could be a ridiculously cheap way of getting a turbo bolted up without a very expensive new manifold. Of course there is a lot more cost to a turbo project than just this piece... Anyway, I'm throwing it out there.

So, it looks like camshafts and adjustable cam timing pulleys are at the top of the list right now. Not an incredible amount of consensus on what to go after though.
