yeah i posted in Wanted for a LIM.
thanks, i appriciate the help
I got the one stud backed out of the EM flange, the other one moves back and fourth but doesnt want to turn fully, its soaking again in AC Delco penetrating fluid.

Could not remove that stud from the flange, it just will not go anywere...
Tomorrow my dad is taking it to work to have a welder tack a nut on the end of that so we can back that stud right out.

One out of two ain't bad. You'll get it. Mine were tough too.

had a look around for some LIM'*...150 dollar average asking price used at a junkyard.
god damn it.
one on ebay, ships to US only, going for 15 bucks.
Im worried i will buy another one and screw it up as well, the carbide bits i used, six of them did 4 ports , thats running the bit all the way in as far as the dremel allows and porting as much material in and as deep as possible..
the tile cutting bit removes material in a hurry, but easily gouges the material.

I used one carbide twist cutter to do all 6 ports and clean up the coolant passage outlets as well. Use a lubricant while cutting, and when the bit loads up with aluminum, use a mild steel or brass toothbrush to clean it out. Dip it in lube (oil) every now and then while it'* hot to 'shock' the loaded material loose.

Basically my tile cutting bit then?

?

uhh yeah, the one i have, is more like a drill bit, with a few more burs on it that are sharp, it allowed me to port like a good three inchs into the ports them selves..it looks like you didnt go that far in Bill?

That bit was long enough to make the port an even 0.9" by 1.9" all the way in, and even long enough to smooth off the 'hump' on the lower part of the inner port. Because it doesn't have a flat face, there were no abrupt edges left behind.

I believe Dremel makes two or 3 sizes of this. I have 2 of them. This is the larger of the two.

Matt...if you are still having a problem finding the intake by Friday, let me know.

I've got friday off and last I knew there was a motor less supercharger about 45 minutes away in a yard. Whatever cost plus a little gas and shipping costs...it'* yours.

Should be cheap.
