Porting intake?

[qwic87gn]

I'm thinking about trying to port match my intake to felpro 1200's and need to know what you guys have used to do this with. I figure on using a die grinder and maybe a dremel, but what kind of stones/bit can be used that wont need constant cleaning because of the aluminum gunking it up?

You can use sanding rolls or carbide burrs. Both work OK if you dip them in grease or WD40 every so often.

Thank you.

Use a carbide flame tipe burr with the cross hatch cut, not just the single. And I would recommend you use a real die grinder to save time and your wrists. I used a dremel to port a set of iron heads so it can be easily done, just the air tool is easier. Make sure you get the top of the intake port as straight as possible and work to get the floor the same way. Lots of little tricks to it, I really enjoy that type of detail work though.

Oh, get a long cutter if you get a die grinder, one with a 6" shank.

And,,, don't go wild on it! The first one I ever did, became a lovely flower pot when I was finished, due to my extremely liberal grinding. Be sure to mark it up with the gaskets in their installed position, and then DON'T cut outside the lines. The key here is to be extremely careful, and moderately conservative. These intakes flow quite a bit as cast, and all you really want to do is match the ports, w/o killing flow velocity. Don't try to make sharp edges on the inside either.
Cut the EGR tower out, if you haven't already. Smooth it down. Slightly clean up areas inside the intake, but spend most of your efforts around the exterior ports.
If you go too far, you'll be spending around $250 for another core, or, you'll be stuck with subpar performance.

There is truly an art and science to doing this type of work, and it's not something that you just "know" how to do on your first attempt. Leave the heavy porting for the pros, and just concentrate on a nice, clean gasket match, which you can certainly accomplish successfully.

This is merely my experiences from doing 4 of these things over the years... I found that "less is more".

I really appreciate the tips guys. I really dont plan on doing that much, just gasket matching.

Thanks again!

Roger,

Did you raise the floors?
