My New '94 RX-7 - Oh, the Drama!
First off, I just wanted to pay a special thanks to my brother David, over at Lethal. He spent countless hours on my car in such a short amount of time, to try and get it running by the time I came home for Leave during New Years.
I'd also like to thank Kyle, who without his awesome welding skills, my car also wouldn't be what it is today.
My brother is so meticulous and his attention to detail is one of a kind. You won't find a mechanic anywhere who is more concerned about your own car than my brother. I'm proud to have him as my brother.
For the initial setup, I was going to be going with a 13B-RE, the Cosmo 2-rotor motor. The intake manifold piping diameter is roughly 10mm larger than the standard 13B-REW manifold.
As my Dyno pic from Lethal will show, the 13B-RE is capable of producing more power at RPM's past 6,500....However, the 13B-REW that is currently in the car, produced significantly more torque and horsepower at LOWER RPM's...which for a rotary, is a definite plus.

Pay no attention to that GT40 on that Z28 /w 345's on the back. ^_^
Dirty Turbonetics 62-1 turbo! >_<
Nice and clean!!
Custom-fabricated fuel-rail. Go Kyle gooooo!

Finished Product: 13B-RE
On the Dyno @ Lethal, awaiting tuning from Roy.
BUT THEN!!!!!!!!!!!!!!!!!!!!!!
Trouble struck.
After being tuned by Roy, as the car was sitting there idling....it died....and wouldn't start back up.
The next day at the shop, after testing air, fuel, and spark...a simple compression test showed low compression on the rear rotor.
It didn't help that the diaphragm of my Turbosmart 45mm waste-gate had a tear in it...causing unsafe levels of boost during the initial dyno tuning, before I had came home. By the time we had replaced the diaphragm and put her back on the dyno, it was too late. :[
....SON OF A........lol...I never even got to drive it with the RE in it. :[
SO!!!!! It was off to JHOT Imports, out of Augusta...to pick up a fresh, low-mileage 13B-REW motor. The standard FD motor. No one in town had a 13B-RE in stock.
Yaaaaaaaaay.... -_-;;
Thank goodness for Verizon's GPS...the Mapquest directions SUCKED, and don't even get me started on how useless then iPhone GPS is!
"What's that, Hamilton? Is that a cop behind us??? Uh ohhhh...."
79 in a 65....ALOT better than a 92 in a 65, which was how fast he was actually going.... OOPS! ^_^;; Sorry Kyle!!
On the way back from JHOT with our precious cargo!
My girlfriend was such a little trooper! Coolest girlfriend, ever!
While we were gone, my brother was hard at work, removing the 13B-RE.
GOOOOOOOOD BYE "rats-nest". ~81 total vacuum lines come standard on the 13B-REW, in order to make the stock twin-sequential turbo system work.
So here she is! After spending the first half of my Leave period at the shop, and a few pissed off girlfriend moments later....
All done and ready for a final tune by Roy.
The 13B-REW versus the 13B-RE, utilizing the "Average Guy" roller weight setting on Lethal's Dyno.
Observe the significant horsepower and torque differences. The RE puts out slightly higher horsepower at higher RPM's, however the REW starts its powerband and torque curve much sooner thanks to larger exhaust ports, resulting in a faster turbo spool.
We decided to try seeing what kind of #'s the car would put out on a standard Dynojet Dyno. So we hit up Dynolab in Marietta and here's the difference.
So if you look back at the Dyno comparison from Lethal..You'll see about a 50hp difference. If you're looking for those bigger #'s, and you're tired of being butt-hurt by Lethal mean dyno....ask them to put the dyno on the "Nice Guy" setting. It'll put out #'s equal to that of a standard free-spinning Dynojet dyno.
Okay, so I got a little camera friendly with my new toy! Sorry I don't have any Photoshoot quality pics, like all you rich bastards. I don't make THAT much money in the Navy! ;D
SOOOO....Happy Birthday, Christmas, Hannukkah, Congrats on Making E-5 to MEEEEEE!!!! LOL
My girlfriend was happy to finally sit in it, too. haha!
Team Lethal. REPRESENT!!!
LOVIN' my '99 Front w/ H4 Bulbs!
And my '99 Tails..JDM tite! lol
Sex.
So all in all....The car runs BEAUTIFULLY. The 11psi is VERY conservative and will help keep it as "reliable" as possible...if that's even a word you can say in the same sentence as "rotary". lol
It's currently sitting in my mom's garage in Roswell, but it'll be up at the shop at least a few times, I'm sure. Advertising. :P
So again, I just wanna say thanks to my brother David, and all the guys at Lethal for helping me get my dream car up and running!
When I re-enlist in < 2 years, I think I'll go ahead and go through with my 2JZ project. Till then, I'll just be cleaning it up a little bit. Touch up the paint, a little body work, a few interior pieces...and definitely throw on my WORKS Emotion XD9's on her as soon as I ship her to San Diego, in April-ish of this year! 235's aren't NEAR wide enough to keep this beast under control! XD
I was even able to get the vanity license plate I wanted for it, too.
"1337 FD"
1337 is actually my NEC ("MOS Code") within the Navy! Go figure! ^_^
Thanks for your time, fellas!
