Has anyone with a magnacharger replaced the throttlebody with a FAST/TPiS unit thats a 90mm or so?

The Mag is not compatible with larger TB's due to the housing inlet size from what I've heard. I know 99Z51R aka Eric is running a larger one...maybe a BBK?

 

[Z16-C5R]

I'm running a bbk with mine, it came with a spacer to allow clearance issues, but because of the down angle on the maggie I had to remove the spacer. (It put too much constriction on trying to get the air bridge on and positioned coerrctly) I've had no issues without it though.

Thank you fella's. I've been wondering this for a while now,..BBK it is.

(and I know what you mean about the air bridge, and trying to get it lined up properly,...what a pain)

Thanks,
