6-Rib Setup
 

Does anyone know of a hotside 6-rib setup that maintains the use of AC and PS, or is it a given that they both have to go?

BRP used to make one. My 2000 had both A/C and PS and used a 6 rib pulley. You can still find them if your patient.

To my knowledge nobody makes a hot side Eaton type supercharger anymore for a Miata.

I think I found what I need. I already have one of the original 4 rib BRPs installed, and found a BRP 6-rib/big throttle body kit. Hopefully it won't be too much of a pain to install. A little worried as the kit has no instructions.

I think I have PDF files for the 6rib big throttle body install. I'll look tomorrow.

Thank you sir.

Sorry for the delay @gthill13...

1. This thread is pertinent: https://www.miataturbo.net/superchar...install-89965/

2. BRP Installation instructions for 6 rib are attached to this post.

This is so perfect. This is the exact kit I found. If you are ever in Atlanta beers are on me (seriously).

Thanks. Glad to help.

It has taken a bit, but the big throttle body and nose rebuild is complete. Hopefully just a few more weeks to get it back into the car.

I havent seen an update to this for a while so I hope it came together. My dad and I installed a BRP 6 rib in my recently. Happy to assist with photos, advise, etc. We are by no means experts, but that may be advantageous; from one novice to another. You can see bits and pieces here or a full write up on mostlymiata.net.

Not enough time and too many projects. I am hoping to put the supercharger back in the car this weekend. Still need to put the new nose pulley on and the 6-rib crank pulley.

I tried to access your link, but it wouldn't let me access. I am always open for assistance. Thanks

Here is a link to our page: BRP M62 Supercharger Install - Mostly MIATA
There are 10 sub pages. Just let me know what we can do to help.

The picturesare extremely helpful.

I am putting the blower in the car today. Hopefully not too many issues.

Blower is in. Will need to align and tighten up once I get the crank pulley swapped out. Also, had to order a bigger throat air filter as the one I had would not fit the new inlet. Maybe two weeks to complete due to travel schedule.

Would love to see your new intake setup when its done. I was using the flex hose, but it moved too much, causing holes when it'd rub. Even at only 11psi, when I tried switching to Silicone tubes, they'd collapse under vacuum caused by the SC. I spliced in aluminum couplers every few inches for strength. it's been hard to find 3" intake piping with tight bends though to avoid the firewall and double-back under the hood. Right now I'm using Frankenstein setup of all three and still get holes from rubbing.

I may have to go with a custom welded inlet tube, I guess.

have you looked at siliconeintakes.com. They have a lot of options. I was able to make a 3" ic pipe setup with the parts they offer.

Thanks, I forgot they had aluminum piping and they have much better documentation on the dimensions so I can figure out the centerline radius. Was getting frustrated on eBay.
