savanna – rx-7 – sa22c

The 1st generation of the Mazda RX-7 is produced from 1979 to 1985, featuring a 1146 cc twin-rotor Wankel. The RX-7 was a direct replacement for the RX-3 (both were sold in Japan as the Savanna) and subsequently replaced all other Mazda rotary cars with the exception of the Cosmo. Early models of the SA/FB RX-7 came with the 12A engine wich has roughly 100hp, the 13B was introduced in 1984 an had a whopping 135hp. The RX-7 featured some really nice technical details: 4-link rear suspension, Watt’s linkage, 50/50 weight ratio, total under 1100 kg. If you want to find out more on Wankel’s and stuff, go wiki yourself 🙂

 

 

 

meet imaizumi-san and his fc3s

No hellaflush, no hardcore racer. No funky vinyls, no extra expensive wheels.

So, what makes this FC so special? Is it the oversized GT wing, the carbon doors, …?

No, it’s the fact that this FC3S runs 57 second lap times @ Tsukuba, then he changes wheels and tires, dissembles the GT wing and drives home! Yeah, right, no trailer, no big pit crew. Just pure motivation.
And if you need some work done @ the track, just give a hammer to your kid!

The FC3S belongs to Imaizumi-san, founder and owner of Super Now Engineering http://www.supernow.co.jp/ A company that develops and produces Mazda performance and racing parts.
The car has been on a serious diet. Race trim includes lots of lightened body parts including the carbon doors and the FRP rear hatch.The curb weight has been dropped to 1080kg. For the car’s wheels, a number of set ups have been tested. In the rear are a set of 17″x10″ Panasports and the front wheels have gone back and forth between a pair of 17″ Enkeis and a pair of 15″ Buddy Club wheels. Imaizumi-san said that he was actually running faster times with the 15″ wheels up front

 

 

Engine wise the car rocks a 13B-REW engine, blown by a Knight Sports high flow and cooled by a V-mount intercooler setup. Internals have been upgraded with Super Now original 3-piece apex seals. 394hp are fed to the wheels by an HKS sequential transmission.
Outside: RE Amemiya fixed headlight front end conversion, carbon doors, FRP hatch, carbon bonnet and lots of diffusers/splitters/canards.
Suspension: Original Super Now coilovers, Original Super Now suspension arms,
What could be better than a grassroots car that can runs Tsukuba in 57 seconds and is driven to and from the track?

 

There’s only one thing I will not understand, why do you want to fit these ridiculous doors on a racing car??
