Pop the lightweight hood and you really do need sunglasses to look at the spectacularly polished 3-rotor engine. This motor is nothing short of an engineering masterpiece. It looks so tiny, and so well integrated, that it just belongs in the FD's compact engine bay. The large triple intake plenum is the first thing rotor-heads out there will notice, a detail which confirms the usual 13B twin-rotor has been replaced by the triple 20B. This engine was taken from a Eunos Cosmo, a large coupe Mazda built between 1990 and 1996. RE Amemiya prepped it up with better performance seals and added a good dose of side porting for good measure, a must when aiming for big power. The large Trust T88-34D single turbo might seem very large, but remember rotary engines (and we are talking of a triple here!) produce much more exhaust gasses per cycle than an Otto cycle engine, so there are no spooling problems.
As ever, RE Amemiya gives a large emphasis on response so it was an obvious choice to go with the GReddy horizontally mounted intercooler. In this position all the piping can be kept extremely short, while the main core makes excellent use of the cool air channeled in from the front bumper; and the hot air which has passed trough the cooling fins is immediately expelled from the openings on the vented hood.
Trust lightweight aluminum pulleys cut strain on the engine adding to better response and overall performance. Engine management is courtesy of a Motec M800 ECU that had to be custom wired into the car and carefully mapped. With so much polished surfaces, it is very strange that the window washer tank looks like something out of a World War II vehicle! The small nylon bag is actually a Nissan part, and as Ken Amemiya assures us it is a temporary detail that will be eliminated once a suitable container is welded up. Keeping the front structure nice and rigid is an RE Amemiya strut bar, while the Quantum fully adjustable suspension kit offers a good trade off between racecar-like handling and sportscar-like comfort.
Open the drive side door via the red carbon-look door handle and you are instantly aware this is a show car. The whole interior has been custom finished with details only RE Amemiya could come up with. In order to match the red exterior all the plastics have been sprayed red and are joined by red carbon-look detailing, red leather and, of course, the red Bride racing seats. The stock Mazda steering wheel, which was taken from a late generation FD, has had its center section color matched while the steering column trim has been layered in carbon and houses the RE Amemiya boost gauge.
The main instrumentation is again custom made and set off with the two Japanese characters of "Amemiya." Alpine supplied the latest HDD Navigation unit, which features a pop-out LCD touch-screen and is able to keep Amemiya-san out of congested areas of the city. A GReddy e-01 boost controller has been fixed on the passenger side of the dashboard and is easily programmed by a small remote control. Helping to keep an eye on engine vitals are a set of GReddy gauges, which display water and oil temperatures as well as oil pressure. As a touch of class, Amemiya-san decided to fit a carbon rear-strut bar taken from the Super GT racecar, an item rotary fanatics would kill for!
The Super GReddy 7 is an impressive car to say the least. It's the last in a lineup of many cars built in collaboration with Trust/GReddy and a vehicle that embodies what this particular tuning shop is capable of. Once fully broken in, Amemiya-san will attempt to run the car flat out on the wangan stretch of highway to see what kind of top speed she can pull. There is easily more speed potential there than 300 km/h, and we are sure it will not fail to impress.
