Search for CIS throttle body mod vendor
I am looking for the vendor that at one time advertised machined your 911 OEM 2.7 throttle body to a larger dia. and included the matching butterfly. Might anyone out there know the contact info?

I am feeding a '89 3.2 longblock with a '79 (lg runner) CIS system and the performance is quite good from 3500~7000 rpm and to the layman it looks like a 2.7. I was thinking that with the > in displacement it could use additional cfm at that point.

If you must I think there was a company that advertised in Pano. I haven't seen their ad lately or haven't noticed it, but if you pick up a Pano or Excellance for a couple years ago it should have an ad in there.

The company I recall machines the TB and fits it with a new flapper. Not extrude hone.

i put the throttle body from a 3.0 on my 2.7. i am surprised more have not done this. i did not get much response when i posted about it. i cant tell if it made a diff since i had a bad injector line when i put it on. i would think the only place you would notice is WOT.
i was looking at a 930 TB, but i dont think it will work.
