FujiRacing ITB Kits

FujiRacing · 12-30-2009, 06:13 AM

This is what made us famous worldwide from Europe-Asia-Down Under.
Sometimes you will see our ITB Kits called IRTB.We put the R in there for Racing.

Our Throttle Bodies are made in Japan and for the Rotary we offer 47mm and 50mm TB's.

They Bolt Directly on a Sidedraft Intake Manifold from Weber-Mikuni-Harada-Dellorto and OER.

To use it with a Downdrft Weber you would need an adaptor made, one Flange to the Intake Manifold side (Weber Pattern) and the other to our TB's.

In our Miata (Piston Motor)we won overall street class in the Redline Time Attack at VIR 2008. You may never see a Miata do that again beating alll the Evo's & STI's with the 1 lap america winning driver in a well prepped AWD car along with Tarzan Yamada in a previous well prepped AWD car. Followed by 2 Modified Time Attack wins beating another well known name.

In CSP Autocross a few years back with hardly any suspension tuning the Natl. Champ that year needed a re-run to beat us in a Tour event. We had less engine and prep. time. I had a very very good driver and if our driver that won the SCCA SS class was driving I think the outcome would have been predicted. We proved that yes a ITB Miata could compete on the Natl. level and we moved onto the Time Attack.

This past September Miata's @ Hallet we set the Fastest time on NT-01 100 UTQG tires with over 80 Miata's in attendance. We had 184 WHP @8200 RPM on pump gas.

Tsuchiya (Drift King) taught me years ago what ITB's do with the Corolla. Now having said all that I get to put our ITB's on my favorite motor which is the awesome Rotary and we will be able share the tech. side of things and assist you regarding ITB's.

The pic. in the middle is from Anniversary Racing Factory in Japan and has the Adaptor in between the TB's and downdraft Intake Manifold.

Thanks! If there is something Miata or Rotary parts you need LMK. We can even build BP and Rotary motors along with transmission and rear ends. Have a Weber-Mikuni-Holley not a problem.

I have a Miata FujiRacing IRTB and would like to know the source of a replacement TPS. Is this TPS used on any US production car?

What happened to Fuji? The website is gone, have they gone out of business?
