FEED RX-7 (Fujita Engineering FD3S)

Photos: https://www.facebook.com/JDM.clips Established on 1982, Fujita Engineering (or FEED) is now a 30-year old company. Yet, their passion for rotary motorsports is as hot as ever. The FD3S in this video was their new shop-car, built to become "the fastest street-legal RX-7". As a matter of fact, this car has already proven to be the fastest. On December 2011, it won the class championship of the country's hottest time-attack event "Tsukuba Super Battle". 3 months later, on March 2012 when this video was shot, once again Fujita Engineering was at Tsukuba Circuit to verify what they had been developing throughout the winter was correct. Under fine weather, brand new Advan tires, and having the right driver, the car marked 57.511 sec at the attack at end of the day - beating their own Super Battle record by 0.5 sec. Looks like Fujita Engineering RX-7 is going to win the time-attack again this year. [Car Info] - Attack Driver: Nobuteru Taniguchi (particularly on this day) - Tires: Advan A050 295/35R18 - Wheels: Advan Racing TC III 11.0J+30 - Remaining Devices, Air conditioner, audio equipment, catalyzer, H-pattern shifting - Honors: Winner of 2011 Tsukuba Super Battle / Street S-class (58.051 sec) [Fujita Engineering] - English: http://www.fujitaengineeringusa.com/index.html - Japanese: http://www.fujita-eng.com

RX-7 FD3S BEST OF
A tribute to one of Mazda's best sports car of all the time! The RX7 FD3S! Best of street race, drift, burnouts, crazy Dynos and more! Check the New Supra Compilation here: https://youtu.be/HQvEEZ0Vw2s Best Wheels you can find! Bid dish, big concave: https://youtu.be/PyzZF9XG2lU The third generation of the RX-7, FD (with FD3S for Japan and JM1FD for the USA VIN), featured an updated body design. The 13B-REW was the first-ever mass-produced sequential twin-turbocharger system to export from Japan, Boosting power to 255 PS (188 kW; 252 hp) in 1993 and finally 280 PS (206 kW; 276 hp) by the time production ended in Japan in 2002. In Japan, sales were affected by the fact that this series RX-7 no longer complied with Japanese Government dimension regulations, and Japanese buyers were liable for yearly taxes for driving a wider car compared to previous generations. As the RX-7 was now considered an upper-level luxury sportscar due to the increased width dimensions, Mazda offered two smaller sports cars, the Eunos Roadster, and the Eunos Presso hatchback. The sequential twin turbocharged system, introduced on this series in 1992, was a very complex piece of engineering, developed with the aid of Hitachi and previously used on the exclusive to Japan Cosmo series (JC Cosmo=90–95). The system was composed of two turbochargers, one to provide Boost at low RPM. The second unit was on standby until the upper half of the rpm range during full throttle acceleration. The first turbocharger provided 10 psi (0.7 bar) of Boost from 1800 rpm, and the second turbocharger was activated at 4000 rpm to maintain 10 psi (0.7 bar) until redline. The changeover process occurred at 4500 rpm, with a momentary dip in pressure to 8 psi (0.6 bar), and provided semi-linear acceleration and a wide torque curve the throughout the entire rev range under "normal operation". However, under performance driving the changeover process produced a significant increase in power and forced technical drivers to adjust their driving style to anticipate and mitigate any over-steer during cornering. Many owners modified their turbo control systems into a parallel system by removing the Exhaust manifold turbo Control Valve and the turbo coupling "y-pipe" Charge Control Actuator and valve in order to remove the changeover process and to simplify the control system for reliability. turbo lag was greatly increased below 4500 rpm, but smooth and linear Boost could be obtained. The stock turbo control system used 4 control solenoids, 4 actuators, both a vacuum and pressure chamber, and several feet of preformed vacuum/pressure hoses all of which were prone to failure in part to complexity and the inherent high temperatures of the rotary engine.





1993 Mazda RX-7 Restoration & Rebuild Project PART1
Source: http://www.stanceworks.com/forums/showthread.php?77316-Saving-a-1993-FD-400 -whp-widebody-shaved-bay-etc Author say, "that recently picked up a 1993 Rx-7 R1 this spring and have been working on it continuously since then (had it shipped from out of state). Plan is to shave the bay, decide on a widebody (already have the burnout kit but cant decide if I want to run it or not), and decide on a motor (already have the ls1 and t56). Not exactly sure on mileage because carfax shows 18x,xxx as the last mileage and the cluster isn't original to the car and shows 8x,xxx. I wasn't worried about mileage though since nearly everything was replaced (and I won't feel bad driving the car a lot and racking up the miles). Previous owner rebuilt the motor, made a vmount setup, installed ID 750/1000cc injectors, walbro 255 fuel pump, rebuilt differential, all new superpro bushings, os giken twin plate clutch, stance coilovers, haltech ps1000, 3" Exhaust, ST sway bars, and a few other things. It came with a spare transmission and stock turbos as well. Oh, and it has work xt7 wheels which I will be selling here soon. I picked it up for what I thought was a steal, but upon getting the car here I feel it was still a good deal, but not as good as I thought. ( I knew I was taking a chance buying it without being able to see it) "





Mazda RX-7 Veilside Fortune in London!

I didn't include any detail shots, but I'm sure I'll see it again once it's had a bit more work done on it. Flickr: http://www.flickr.com/photos/adamcanfield/ Tumblr: http://adamc3046.tumblr.com
