1975 911 RSR Backdate 3.8L Engine Conversion and more!

This 1975 911 was backdated to a 1973 RSR style and received our 993 3.6L to 3.8L motor package. The car also had a fully adjustable RSR style suspension installed.  The 915 transmission was also addressed and we installed a lightweight stage 1 flywheel and clutch for improved throttle response and smooth engagement.  A limited slip differential helps keep the power planted on exit.  A 993 turbo brake package was installed to enhance stopping power as well. Enjoy the video!
