We went with the RX-7 FD Drive By Wire Throttle Pedal Mount V3 Kit from Z Precision who built this pedal mount specifically for the 5th Gen Camaro DBW pedal and the FD RX-7.
This comprehensive mounting kit from Z Precision can be purchased with or without the pedal and is designed to be rigid, lightweight, and adjustable in all three axes – up/down, left/right, and front/back.
The as-delivered position places the new pedal in the same position as stock and is true to their goals, this pedal assembly is SOLID and feels like the car was designed with this DBW pedal from the factory. Having searched for the best DBW pedal solution, the Z Precision DBW pedal mount is absolutely the way to go for any FD owner.
This Camaro DBW pedal is the perfect shape and size for the footwell of the FD RX-7.
The DBW pedal has a 6-pin connector that will need to be wired to our ECU. Ensuring your ECU has enough available channels and assigning the channels correctly is very important.
There are two factory mounting studs for the throttle pedal on the firewall.

This is a no-stone-left-unturned kind of build and I am glad you are documenting it! I hope you make a video at the end covering everything you have done over the years.
Thank you. We will do a video recap at some point.
I had no idea the stock TB was so complex. It’s actually pretty cool, and I’m sure it was a great setup for a stock or closer to stock engine, but I can only imagine the new e-throttle will give far better drivability and support making more power on the new engine.
but a 5% reduction in size… I’m surprised they didn’t find an option that was just barely larger, instead.
If you consider the throttle shafts into the equation, the effective area is actually the same. I would imagine that a single butterfly impedes flow less than several smaller ones.
LS3 throttle body is 90mm but the motor is huge and probably wouldn’t fit very well here.
What bothers me most is that the throttle pedal spacer in installed the wrong way up. That’s going to cause some serious issues.
Lol. You’re right. It’s upside down. Well, should be an easy fix.
Ha, you’re right. Good catch. What serious issues will it cause?
It will cause no issues whatsoever. It just doesn’t line up with the opening in the carpet and that’s too much for my OCD.
GrantC – There’s a hypothesis that a much smaller 74mm TB will perform better at power levels up to ~500whp… That might need testing.
