Since the price on SVT UIMs are sky high these days, I was wondering if it would be best to just take a dremel and grind everything to a larger port size. I have an SVT LIM sitting in my garage right now, along with the SVT TB. The only thing is, I won't have that smooth finish on the inside of the manifold right? It will be bumpy like the outside. How can I go about fixing this? I have a lot of spare time, just not the cash to spend on an SVT UIM.

How would you be able to reach all through the runners? If you cant reach the runners, you will end up distorting the air flow and actually making the flow worse. Just save your money....maybe Ebay will have one pop up some time.

Dremel makes a flexable extension tip for hard to reach places. But the chances of you boring out each one to the precision you'd need would be neigh impossible.

How do they do it? With specially crafted tools....like the Roto-Matic as seen on TV by Billy Mayes.

I was just wondering because I was searching for threads about the SVT UIM and I found one from a while back and somebody mentioned that it can all be done with dremel at a cost of about $150. I don't quite understand what that means.

They extrude hone the UIM. Thats what makes it larger and a polished look. There are still comapnies out there that will extrude hone your UIM if you are interested...but it still may still cost you a few hondred dollars. I dont think SVT dremels there parts....atleast i hope not.

It can be done like this...



and this...




Use a drill, bit extension and various sanding drums/stones. Along with many hours of your time.

The company that did them for Ford was called Extrude Hone, they even use a picture of a CSVT on their site. You could send them your UIM, and have it dual honed (SVT UIMs are dual honed), but it is quite expensive.

yeah, I believe extrude honing uses an abrasive putty and forces it through the runners to make them larger and smoother.
