where did you get the plly and how much. they charge to muchs at most webs. even they cost more more to make for cheves - but charge more cus it is a MB.

the boring of the throttle body; did you have to enlarge the butter fly? is it just a straight bore or over bore. the orginal body tapers in the midddle, did you just bore out the taper?
if bored completly, how much is the over bore?

bore

where did you buy the pully, they cost soo much just becuz it is MB

the throttle body if tappered in the middle and back to size at the bottom.
did you bore out the tapper, or over bore it completely?

About power mods, again, don't chime in here thinking this is some cheap-*** upgrade that will make a HUGE difference...be ready to spend some money on this platform or don't even bother (I've heard and done it all). More details later...

ok, i dont this to cars i've had in the past. but,,,,isnt it hard to get the throttle body, on a c320???it is down past the m.a.p. between the motor and firewall. i cant even see it -or am not looking at the wrong place?
