Project LSX-7 Update 16 – Cooling System & First Spin of the Drivetrain

LS Swap FC RX-7 Cooling System It’s no secret that LS engines have been swapped into RX-7’s for years. The benefit of being a fairly common swap is that there is quite a bit of information about how to construct an adequate cooling system. After doing some research, I discovered a company named Jags That…

Project LSX-7 Update 15 – Clutch Master Cylinder Install

In update 14, I went over the installation of the T56 transmission and driveshaft. Since the clutch slave cylinder is an internal type, it was installed during the clutch and transmission installation. To make the GM slave cylinder function correctly, a properly-sized clutch master cylinder must replace the stock FC clutch master cylinder. LS Swap…

Project LSX-7 Update 14 – T56 Transmission and C4 Driveshaft Install

The most difficult part to source for the swap up until this point has been the T56 transmission. T56 transmissions are typically found in LS1-powered Camaros and Firebirds (along with many other sports cars). They are a 6-speed manual transmission capable of handling over 450 lb-ft of torque in stock trim. Since so many cars…

Last year, Mike competed in the Pro Am drifting series at Evergreen Speedway where he placed 1st. This meant that he…

Project LSX-7 Update 12 – Stage 1 Fuel System

Another area of an RX-7 that needs to be upgraded for an LSX engine is the fuel system. Even though the stock fuel pump is capable of flowing well enough for a stock engine, the pressure of the fuel needs to be regulated before it enters the fuel rails. I found a helpful post on…

Project LSX-7 Update 11 – Rear Subframe Modification and Bushing Install

As I mentioned in Update 10, the Turbo II rear end was one of the most valuable pieces of the entire parts car. Instead of pulling the differential, axles, brakes and hubs and swapping them over to Project LSX-7, I decided to just use the entire Turbo II subframe. This made installation easier and since…

Project LSX-7 Update 6 – Parts Engine Teardown

From this post forward, Project FC RX-7 will be referred to as Project LSX-7. After purchasing the L33 engine, numerous parts were required to make it fit in the RX-7. The search began by looking for accessories and an oil pan from an F-body (1998-2002 Camaro/Firebird). After searching for nearly a week on LS1Tech and…
