Probably going to get flamed for this, but I've searched to no avail...

How have people fastened down their Divided T4 housings?! I'm making a DIY kit with an RX7store divided GT35r, and there's next to no room by the mounting holes to put anything there. Studs and nuts are out for sure, the only way I can see to do it is to ground the housing (with it apart from the CHRA, obviously!) and use hez socket heads.
Is that OK to do? I'm a little worried about grnding my brand new not particularly cheap turbo housing! Is there enough material to not weaken it?
Cheers

I used bolts coming up form the bottom and small diameter nuts. I had to drill and safety-wire the nuts to ensure they didn't back off over time.

IIRC, those housings you can put the bolts in through the manifold first, nuts on the turbine housing. Use threadlock.

If it's a older 1.06 casting yes you can get a 1" diameter sanding drum on a die grinder and with a steady hand grind in enough room pointing the grinder downward. I used to do that before I shipped those out a few years back. I think the newer castings resolved this but can't remember.

It was from RX7Store, bought about a month or so ago, looks like an ATP casting for the housing.

There's no way I could get a nut on there unfortunately, even if I went through fromt the other side (and the mani flange is threaded, so I'd have to drill out the threads)
I think grinding's the way to go. Cheers guys
