The SerialNINE cd999 Technical Shifter comes with a multi-position offset shift lever. With the shift lever mounted in the most rearward position, the shift lever was in the same location as stock. We covered the advantages of this high quality CD009 shift kit in Part-18.
The Fisch Racing Tech RX7 FD Transmission Crossmember and Energy Suspension transmission mount bolted perfectly into the location of the factory chassis brace. Due to the Power Plant Frame (PPF) design of the RX-7’s factory drivetrain, there is no rear suspension mount to the chassis. The entire OEM drivetrain is held in by 2 motor mounts and 2 rear diff mounts, which we covered in detail in Part-8. The Fisch Racing Tech Crossmember turns these chassis mounting points into a traditional rear transmission mount.
The CD009 is a substantially large transmission, but it fits perfectly in the stock FD RX-7’s transmission tunnel without any contact, even with the additional thickness of the Heatshield Products Sticky Shield thermal barrier in the transmission tunnel to reflect exhaust and drivetrain heat out of the chassis and interior cabin.
The built engine now sits in the engine bay for the first time. The billet DC Power alternator an blue Raceonly pulleys look great and bring a bit of color and character to the engine bay.
We bolted the subframe onto the chassis and reattached the vapor blasted control arms that recently had the SuperPro polyurethane bushings installed in them along with our SuperPro front Swaybar and billet competition Swaybar mounts. Our FD is now technically a ‘roller’ again.
The Fisch Racing Tech CD009 bellhousing adapter and transmission mount look like they were meant to be in the FD RX-7 chassis. The entire drivetrain from the billet Built 2 Apex baffled oil pan, powdercoated front subframe, and blue Explorer 8.8” rear differential make the underside of our FD quite attractive. The transmission tunnel looks great wrapped in the Heatshield Products Sticky Shield thermal insulation which should keep the cabin cool from all of the exhaust heat and transmission heat that this beefy setup will produce.

Every update on this project is fantastic! Keep up the good work and keep all of us entertained with this awesome build as most of us go into the cold months with much less track action.
Absolutely love this build series, my dream car
Still a very exemplary build.
One thing though. The trans crossmember looks unnecessarily complex for a simple part. If You really need to make it from billet, mill it from one single piece. The bolt-together construction is just silly. This part could have been made from steel 2x thinner and just welded.
Milling it from a single piece would be extremely expensive and actually more complex. from what it looks, the current design is just cut out from an aluminum sheet on a CNC router. And this aluminum design looks sick.
Kakui!!! (Cool!!)
It is crazy how physically tiny that rotary engine is! It’s literally smaller than the transmission!
