geordieggg Posted January 30, 2007 Share Posted January 30, 2007 I'm about to perform the 60mm TB upgrade as so many on here have done successfully before, but have some queries about the standard TB that's currently fitted. Pics of the offending item: AFM side Manifold side Underneath I'm worried about the vacuum ports underneath and what they actually run. One of them goes to the dizzy, one to the heater vacuum canister, a third to a little thing that sits on top of the thermostat housing and the fourth I'm pretty sure just tees in with the dizzy one. I'll have a good look when I get the car back (at the panel beaters now, thanks to an idiot mechanic ). If I do away with this throttle body, can I just plumb them into the manifold further along? If they need to be run in front of the butterfly to restrict vacuum at idle, then I could be in trouble, I'll need to modify the new tb further. Any Ideas?
