Saw it at DGRR, and wanted to get one for myself. It was on the Canadian 1st gen that blew the diff.

Looks like Fuji or Tweakit.

Its a Fuji ITB setup.

Pretty much what's already been said - they are ITB's made by a vendor on this site - Fuji Racing. Their brand of ITBs are the sidedraft style (Dellorto, I think) with a double injector setup (though I think they now have a quad setup) whereas EFI Hardware's (Tweakit) are downdraft (Weber IDA style to be specific) with a quad injector setup. Neither kit comes with an intake manifold so you would have to either obtain one or make one yourself with the proper flanges.

EDIT: Damn! ninja'd!

Pricey. I've been looking at these as an alternative:

Never heard of them before. Interesting though, as their's are IDF style and only come in a double-injector setup. Nothing a custom manifold couldn't fix though (I've never seen an off-the-shelf-IDF manifold for a rotary).

I would probably just make an IDF to DCOE adapter plate out of 1/4" aluminum, and use the Racing Beat side-draft manifold. I'm not sure I need staged injectors for a 12a.

These TB's are pretty common in the A/C VW world, and can be had pretty cheap used.

Hi guys. Just came across this thread. The car is one of my customers Sam from Canada and those are our FujiRacing Sidedraft ITB's, which is Made in Japan and is the same as OER-SK. Sam has done an amazing job having it work with the Megasquirt.

BTW we carry Jenvey also and if you need something let me know. Just sold a S2000 ITB utilizing Jenvey hardware.
