Why FAS?

A GEN.V Gas or Diesel Conversion Package offers a worry free Under-The-Lid option for the Vanagon/Bus owner looking for silky smooth performance, while not sacrificing reliability or maintainability.

Why FAS? Well…

Let’s face it, the original flat-4 Waterboxer was a failed experiment in every way…be it reliability, dependability, or utter lack of fuel economy; not to mention one of the worse emissions emitters of all time on the planet. It’s the truth; it is okay to admit it. We all love our vans despite their environmental impact.

Sure, there are other attempts at solutions, but “used” Ford and Subaru engines only further complicate service and maintenance horror stories without doing much better in the areas of reliability, emissions, or fuel consumption. Not every individual or shop wants to deal with the science project of scabbing together used salvaged engines and components from around North America to keep their prized people movers going!

VW Mexico, Brazil, and South Africa realized early on after production ceased in Germany, that the future of the VW Bus/Vanagon lay solely on the abandoning of the earlier antiquated flat-4 for the newer in-line watercooled engine designs that have provided worldwide, bulletproof reliability in the passenger car market for over 45 years.

At FAS we take a lot of pride in the sweat equity involved in designing, producing, testing, and finally, providing products that not only work, but work well and are seemingly unnoticeable.  Unlike other companies claiming to have the best solutions, we do not rush product to a niche market without properly testing, and then walk away.

FAS have always been synonymous with high standards, and it is easy to see the quality difference when compared to others in the market. Engines are Brand New, and all of the conversion components are made here in the USA; using the finest materials and equipment.

So powerfully smooth and quiet, it will have you questioning if you are in the right vehicle. No longer are hills and steep grades an issue, merge lanes and pass with complete confidence because the GEN.V package truly transforms your Vanagon/Bus driving experience.

It’s time for you to try an FAS “Turn-Key” solution today and eliminate that “knot” in your stomach when embarking on your #vanlife adventures.

  • Additional Why FAS? Thoughts
  • We do not have turbo oil drain issues. Oil properly gravity-drains into our proprietary oil pan.
  • Our patent pending Hydraulic Engine Cradle System grabs frame rail to frame rail rigidity, to produce a smooth, quiet platform for inline drivetrains.
  • FAS crankshafts are all pre-drilled to allow for proper transmission input shaft mating.
  • FAS spent years dialing in minimal intake resonance and acoustics. VW had it right all along, as far as incorporating an airbox that was as far away from the “D” pillar as possible.

    FAS uses the factory 2.1L wbx airbox for a super quiet ride.

  • All FAS kits include every dash interface: tachometer, coolant gauge, oil light system, and cruise control for free (regardless of if the vehicle had it previously).
  • FAS engine management electronics are 2nd to none. All modern engines absolutely require crystal clear Vehicle Speed Signals (VSS) supplied to the ECM for engine mapping, to perform properly.
  • FAS in-depth installation manual with unparalleled level of detail is provided with each package.
  • FAS uses a fuel cooler (just like all modem day TDIs), a factory VW wbx muffler and tailpipe. FAS allows the use of original factory evaporative emissions.
  • FAS spends little energy on social media…too busy creating products to keep our lovely Vanagons on the road.
  • FAS thoroughly explains to clients why the tire size and gearing modifications are pertinent to installing a modern revving engine in a Vanagon.
