Possible or not

I'm currently using Series 5 13BT housings (turboII?) for my 12a. They are away getting machined down to 12A width. Not really common (although becoming more popular), but easily done. Mind you I'm also using the 13BT end housings so no water seal groove is advantageous for me.
Just do it and have the tooling path allow cutting through the chrome first then into the housing so you dont unpeal the chrome liner. If I had the gear I'd have done it myself.

Yes it will
Removing 5mm on each side ofcourse, not 10 on one side.
Haha everybody thought about this, but I was the only one desperate enough to ask the question
Guess Ill give it a try.

If you don't mind modifying an intake you could use all 13B irons with the grooves in them. Then no grooving of the housings would be required.

I love modifying stuff, "unfortunately" I allready have done the grooving before, so the CNC program could be used again, just needs modifinationcating to do the oil/dowel o-ring.
Thanks anyway, mentor

Earlier this year I was selling an engine with 12A turbo rotor housings. Too bad. They only had 10k miles on a rebuild done in '03. The new onwer is a new member of the RX-7 club forum.
You can't get 12A turbo rotor housings anymore unless you buy them from MAXT.

So I did it. It's possible.
FYI Rotorhousings are pretty hard on the millcutter bits, sure as hell not just regular aluminimums

you know what i was think would be cool. if you could do the grove on the rotor housing keep the one on the plate and instead of using silicone and teflon water seal using some sort of copper ring as the seal. so that you would never have a blown water seal again .think how good it would be...
