When I was deciding on an engine swap, two of my deciding factors were ease of installation and cost. Right around the time I started to research potential swap options, a company named Ronin Speedworks released prototype photos of their FC RX-7 LSX mount kit. These photos helped make my decision a little easier.
Typically, swap kits for non-standard engine swaps can sell for over $1000. Ronin Speedworks sells their Supreme kit for $569 plus shipping. Their Supreme kit includes everything required to mount an LSX engine and T56 transmission (transmission mount not shown).
Since I wasn’t too keen on designing my own mounts and these were so affordable, it was an easy choice. I purchased the complete kit and received it in less than a week. It was packaged well and everything arrived undamaged. The first thing I noticed when I unpacked the kit was the quality of the parts.
As you can see in the photos below, the weld quality on these parts is top notch. Ronin designed the parts to have welds on both the inside and outside. Previous mount kits required that the customer paint or powder coat the parts themselves so it’s great to see a kit ready to install. They even included brand new fasteners to mount all of the parts.
The pedestals are replacements for the cast Corvette mounts that many people use for these swaps. In my opinion they are nicer looking than the stock cast pieces and it’s much easier to buy a complete kit from one vendor.
Since the L33 engine has a 90 day warranty from the time of purchase, I’m planning on starting it without the transmission (the starter mounts to the engine). Once it has been verified that there are no issues, I can purchase the T56 transmission and get one step closer to driving the car. The next update will consist of the engine being prepped and dropped into the car. Check back soon!
