Here’s one car that the Porsche purists and car snobs in general are going to hate. We on the other hand, are finding ourselves wanting to give owner of this 911 a standing ovation. We came across a thread on Pro-Touring.com with a link to a video of this LSX-swapped 1978 Porsche 930 Turbo 911. Upon watching video, we were given the visual proof of something quite amazing – this thing has an LS7 mounted where its original flat six once lived.
After a bit more research, we discovered the 911’s build thread on PelicanParts.com, and we found that this car is owned by a gent from Easley, South Carolina, and that it isn’t just any run of the mill LS7 powering this car; it’s actually a modified LS7 from MAST Motorsports with that is making over 700 horsepower at the crank. The MAST LS7 is bolted to the stock Porsche transaxle through a Kennedy Engineered Products adapter along with one of their clutch packages for LSX swaps. The EFI electronics are handled by a MAST harness, ECM, and drive-by-wire throttle. Also, the FAST LSX-R intake manifold is flipped with the throttle body aiming right at the back seat, which is exactly where it pulls its air from through intake ducts on each side of the car where the quarter windows used to be.
As with most LSX swaps, the headers were a bit of a sticking point since there isn’t a manufacturer that makes a set specifically for a swap into a 911. So, Larry did the next best thing and used Stainless Headers mock-up kit, and sent his design right to the company who welded them up for him and mailed the real deals back to him. The full length custom Stainless Headers dump right out the rear through a set of Flowmaster Hush-Power Mufflers.
All in all, it took the owner just over 9 months to seamlessly blend the LS7 with his classic Porsche. Now that is our idea of time well spent.
