We’re no strangers to building Porsches. Coming off his 1,000whp 1/2-mile 991 Turbo S and his RUF conversion 996 RTurbo, the owner of CSF Race, Ravi Dolwani, has decided to throw his hat in the ring for best Porsche build of the year. This time, going back through the pages of Porsche history with a unique 911 backdate – 73 RSR style with a modern twist.
The car will be debuted at the 2021 SEMA Show, showcasing CSF’s new line of OEM+ Performance Oil Coolers for air-cooled Porsches.
The majority of the build is taking place at SV Auto in La Verne, California. Owner, Simo Veharanta, is a vehicle restoration expert. He specializes in Porsche restorations – this is where his passion and expertise really shines.
We enlisted the help of many previous build partners as well as some new companies from around the world, including:

The journey begins at SV Auto, where we meet the owner, Simo Veharanta – who is spearheading the build. Simo’s an Expert Porsche builder, often found in the pages of Excellence magazine, with a pedigree stemming from his deep connection with good friend Alof Ruf from Germany.
Simo decided to take on building the CSF911 under one condition – the design process would be a mutual collaboration between himself and Ravi, with the ultimate goal of building the most fascinating Porsche 911 backdate ever to be created – a real blend of experience and old school, classic Porsche style with new ideas and modern technology.
Starting December 2020, Jon Sibal had started to create the design that’s now being used as the roadmap by SV Auto to bring this vision to reality. With no time wasted, on January 4th, the team at SV Auto started from scratch and began tearing down a 1982 911SC to bare metal.
No details will be overlooked, no corners will be cut. The Road to SEMA 2021.
Fast forward to March 2021 – as the body work continues on the CSF 911, the engine build is underway at renown Porsche engine builder, Prato Motorwerks.
Simo and the owner of Prato Motorwerks, Fabian Prato, have worked together many times in the past and he’s one of the best in the biz when it comes to building air-cooled Porsche engines.
We dive into the details of the 3.9-liter, naturally aspirated, 400+ horsepower custom-built engine sourced from SSF’s complete catalog of Porsche OEM and high-performance parts.
The key to reliability is not only choosing a knowledgable engine builder, but also using top-of-the-line parts – we’ve chose to go with parts from some of the top manufacturers in the world including pistons from LN + Mahle, custom cams from WebCamshafts, Pauter rods, valve covers from Tarett Engineering, and an array of new OEM Porsche components.
Next, we’ll be finishing up our engine with our custom fabricated GT3 plenum and Kinsler ITB Fuel Injection Kit including drive-by-wire kit. The engine will be finished off by renown motorsports electronics expert, Ryan Basseri from Rywire, who will be making a custom engine harness to sync-up the DBW and Motec ECU.
For the car’s interior, we turned to Rogelio’s Auto Upholstery. We’d used Rogelio’s before, for both our Evo X racecar and RSX daily driver, and their attention to detail is unmatched – it was a no brainer to partner with them to take the interior of the 911 to the level we had in mind.
We wanted to do something understated but over the top at the same time – staying true to classic Porsche interior patterns, but with a modern twist.
We decided to purchase 10 grand in authentic Goyard bags to start. The hand-painted pattern and burgundy color of the bags would be perfect used as the center portion of our Sparco SPX seats. The rest of the interior is wrapped in grey alcantara and leather.
We ended up using three of the bags, which were carefully cut and positioned perfectly vertically, horizontally and diagonally across the seat so that the pattern always looks correct no matter which way they are viewed.
…The final result blew us away and we can’t wait for you to see it.
