Here is a video from when I first got my RE-5. You can hear the purr of the rotary engine.

The frame had collected a lot of rust over the past 34 years, so I decided to strip it all down and give it some fresh paint. I did two coats of Rust-Oleum metal primer, three coats of black, and two coats of clear.

I will have a lot more to come with this project. It will be getting a new wiring harness, custom exhaust, and misc accessories.

My FD Dyno

shep — Wed, 28 Apr 2010 05:08:53 +0000

After owning my ’93 RX-7 FD3S for 2 years, I decided to get a baseline dyno run at our SLCrotary Dyno Day. I purchased the car from a friend as a rolling chasis in 2008. My main focus for the car was to just have a reliable, fun, weekend cruiser. The car is “mostly” stock aside from intake and exhaust mods to help it breathe.

Here is a bit of information about the 1993 Mazda RX-7 FD3S as from the manufacturer via Edmunds.

Exterior
Length: 168.5 in.	Width: 68.9 in.
Height: 48.4 in.	Wheel Base: 95.5 in.
Ground Clearance: 4.5 in.	Curb Weight: 2789 lbs.
Interior
Front Head Room: 37.6 in.	Front Shoulder Room: 51.8 in.
Front Leg Room: 44.1 in.	Luggage Capacity: 17 cu. ft.
Maximum Seating: 2
Performance
Acceleration (0-60 mph): 4.9 sec.	Base Number of Cylinders: 2
Base Engine Size: 1.3 liters	Base Engine Type: Rotary
Horsepower: 255 hp	Max Horsepower: 6500 rpm
Torque: 217 ft-lbs.	Max Torque: 5000 rpm
Drive Type: RWD	Turning Circle: 35.4 ft.

It has the stock 13b-rew motor with the stock twin sequential turbos working almost flawlessly at 12psi. You can hear the bit of hesitation I’m trying to figure out during the primary/secondary turbo transitions in the video.

So, the final results were 244 RWHP and 211 TQ. Overall I’m please with the results, and its right about where I expected. With the factory specs of 255 HP and roughly a 15% drivetrain loss, that puts me about 30 HP over stock. For the next year, my primary focus will be on getting it ready for the track at Miller, but inevitably, I will need more power.
