Good morning everyone!

I will soon be tearing apart a couple of 13b cosmo to port in intakes and exhausts, as well as doing the water jacket mod.

My questions right now do not lie in the porting and dismantling of the motor, but rather with peoples personal preference of tools selection and carbide bits, sanding stone, etc.

I know racing beat will sell me everything I need for tools to do the actual porting, but they seem slightly over priced. I did a rough estimate on their website, and the total for just bits and sanding stones ect came to close to 300$!

now im sure there are some rotorheads out there (probably the fc guys) that have saved a few dollars by ordering these bits and whatnot in Canada.

I would certainly like to deal with a Canadian business but I am not familiar with any online type stores that sell these things in Canada. (a google search will give me options, but I prefer to hear about personal experiences with specific companies)

There also lies a question as to which tools I should be using to do the porting.
Some say the like the dies grinders but they make noise, and the one I have only has a 1/4" collet. Im asuming Ill need something with as small as a 1/8" collet.

I dont think I want to use a dremel, but i am entertaining the idea of buying an electric flexible shaft grinder run off a foot pedal. I think it may be the most comforatable way to do the porting.
Has anyone had personal experience with these types of grinders?? What brand did you buy?

Feel free to add any information you may see as useful for me, or anyone else, Id like the thread to be an open topic on tools used, places bought, and if the quality reflects the price paid.
Thanks everyone!

I do have a dremel accesory kit from CDN TIRE, but I have a suspision that the mastercraft brand may not have used the best quality tools, the last thing I want to do is start porting, then realize the tools I have are ****, and have to wait until I get better ones to finish the job.

Thanks!

You don't need all the tools racing beat lists. I like my Dremel 4000 for intake ports with a stone and die grinder for exhaust ports with a carbide bit. For polishing I use the dremel for both.

Thanks marco!
I was initially looking at the 4000 but was not sure if it would be a good tool for the job

Where do you buy your carbide bits from? Do you have a paticular brand you prefer?

I just used a regular die grinder and a selection of carbide bits to port mine. I also used some sanding bits I got from a local tool store. You don't need anything fancy for the job. I got my carbide bits from snap on but I know you can buy them from a lot of other places.

If your porting your supercharged engine you want to use some caution. Same rules don't apply vs n/a & turbo

Yea this isnt the supercharged 73. This is going to be the motor for my fc and a spare.

Legere carries a selection of bits for air/die grinders, busy bee and others should as well.
Rounded tipped versions give the most utility.
The carbides make quick rough work of the ports but you need to be careful. Protect non-work areas from a slip with layers of tape.
Air grinders are nice and compact but require a compressor and are LOUD!

I use dremel grinding bits/small hand files for more precise finish grinding and dremel sanding cylinders and high grit # for polishing.
Same for water/oil pump/passage mods.

Buy, borrow, steal porting templates or do the research.
Also remember to slightly bevel/chamfer the port closing for softer landing of side and apex seals.
