Tuner Comments:
RE Amemiya are considered the top tuners when it comes to tuning your RX-7, RX-8 or anything with a Rotary engine. So imagine their faces when we tore out their settings, boosted the turbo and started transforming this masterpiece of an RX-7 into a killer. 

However we went a step too far. One night during testing, this RX-7 went on a murderous rampage around Trial Mountain. Nothing could keep up with this Rotary Rocket. We lost Juliet in the madness and we would’ve lost the Challenger GTS too if it wasn’t for the NSX-R 3rd Anniversary stepping in. Is this the rival the NSX-R has been waiting for?
Some say that his garage in Chiba is a Mecca for haters of pistons and that 35+ years of tuning experience has made him a "Rotary God". All we know is Isami Amemiya has unleashed a hellish rotary-powered vision upon the world.

Brand new out of the box you look at this car and think "I'm going to be spending a lot of time looking down the track out my side windows." The stickers, huge wing and flamboyant body kit make it look like something that belongs shredding tires in D1 or FormulaD. Not necessarily true. This car belies its exterior appearance and can stick a corner like you won't believe. Tuned by the best in the rotary business this is no stock FD, as the lap time will indicate. It is very well balanced on power, through corners and on the brakes. Will you still find yourself sliding through a turn? Yes, however power oversteer really only shows up on lower speed corners and is quickly contained. Initial stock lap comes in at 2'04.199".

With the parts list purchased and installed you find little change. The rear is a little more eager to come around but all the control remains as does just about everything else. Coming off a pre-tuned car the lap of 2'01.137" is unspectacular in time difference, but not unexpected.

If you are a fan of RKM and their tunes this is a moment of truth. Roj has put into our heads that his version of Amemiya's vision can rival his legendary NSX-R. So, let's find out. As before with the parts tune the general character of the car is untouched; the balance and control remain intact. However, the steering is now more responsive, perhaps close to being as mentally plugged in as RJ's EvoX. The rear has come back in line; very stable and a feeling of infinite control upon stepping out, eerily similar to the NSX-R. So a few laps then. Right off the bat I came in a hair off 2' flat. Pushing a little harder was easy and that barrier was broken quickly. The sticking point of the lap for me was the final turn. I was coming off the s-curves fast enough that I had to either lift or tap the brakes to get through just right. I had many a good lap taken down by stuffing it into the wall or getting just far enough onto the grass over the rumbles that the rear came unglued. I posted my best time on lap eight. Putting on my best Jeremy Clarkson.. it did it in...one minute..........fifty........eight point eight two! That's right, 1'58.820"! The big, bad, blue rotary-powered devil has taken top slot on the board at Grand Valley Speedway!

But wait! There is the NSX-R scowling in the pit lane. To be fair the champ got the opportunity to defend the crown it has kept for so long. Like a demon it bites and claws at the tarmac hoping to regain its glory as king. Two minutes.....1'59.9"....1'59.7".....1'59.5". And that was all it could muster. After 15 laps the champ concedes defeat and hands over the crown, but not without promising to keep this new rivalry going anywhere, anytime.

And so the RX-7 revels in new found glory and fame. However, this well balanced machine is already gearing up to take on the NSX-R again. Another track, another time, another fight to the wire.
