I picked up an FD chassis last June. I have wanted to do this swap for a few years now but could never pull the trigger and actually buy one. The car is a full street car, air conditioning, power steering, etc. I am using the RX-7 tranmsission with a B2600 bellhousing. We made an adapter plate to fit the Narrowblock 4G63 to the Mazda Bellhousing. I also had to mod the subframe and drop the steering rack to fit the motor. I used the Samberg bumpsteer kit and modified it since I needed to drop the tie rods a bit lower. Just about everything was fabricated/built in house including paint. The car is a blast to drive as it makes 520whp on 93 octane. It dead hooks 3rd gear and slightly spins 2nd gear with 275/40/17 regular Nitto NT05's thanks to boost by gear and traction control via the AEM series 2. With a full tank of gas and me in it the car weighs 2890lbs. This is the setup:
-6bolt 4G63 bottom end
-CP 9:1 pistons
-Magnus Aluminum Rods
-O-ringed Block
-ACL Race Bearings
-Mild Port 1G head
-Supertech 1mm valves
