cost of P&P
 

Generally speaking, how much does port and polishing cost? I have a tb all ready and would like to also Do my LIM and maybe my UIM as well.

I have no idea. Nor am I aware of anyone that does it off the cuff like that on a 3800, nor do I understand what you could port on an L27 UIM. It's thin Nylon.

The lower intake leaves much to be desired. Lots of room for improvement. But there is little that can be done about the UIM or even portmatching it to the TB.

Thats pretty much what I figured for the UIM. But I would like to know the general cost for the LIM and the TB.
