GoWesty Performance Waterboxer Upgrades Are NOT "Engine Swaps" (Updated June 2018)

We have built our industry-leading reputation on our waterboxer engine program. Our staff of mechanical engineers, expert machinists, and engine assemblers have been dedicated to furthering the development of the water-cooled flat four for over 20 years. Our goal is to build the world's most powerful, reliable, efficient, and smog legal waterboxer engines that money can buy. If this is the type of power plant you want in your vehicle, you've come to the right place.

At GoWesty, we believe in the waterboxer. We get calls all the time asking if we do “engine swaps,” like the Subaru or in-line “Jetta” engine. We have carefully analyzed the different options available, and we've had the opportunity to look closely at several vehicles with various engine swaps. We came to the conclusion that we were going to invest our time and effort in developing the waterboxer design in the direction that VW undoubtedly would have gone had they continued to produce the waterboxer.

Our goal is simple: Improve power and efficiency while simultaneously improving reliability.

We don't design or build anything radical here, just high quality engines born from quality engineering and quality parts. Our 2300cc, 2450cc and 2700cc options produce more torque than the commonly swapped Subaru 2200cc EJ22 without creating a white elephant. No special adapter parts, cobbled together wiring, or funky low hanging exhaust and oil pans! As for naturally aspirated inline four-cylinders commonly used as engine swaps in the Vanagon, even the most worn-out, out of balance waterboxer is simply a smoother powerplant. How about turbocharged VW engines like the 2.0T from the Golf, or a TDI diesel? Well, they have some advantages in the power and economy departments, but they also have some fairly serious pitfalls of their own, namely high cost, vibration/noise, loss of ground clearance, and the propensity to destroy axles and transaxles. Ask around, you'll see.

Bottom line: dollar for dollar and ft-lb for ft-lb.—the Waterboxer just can’t be beat.

We offer three waterboxer options above the base 2200cc engine. Even our base rebuilt waterboxer is a stronger-than-stock engine, but with the following three higher output engine options you get all of the regular items included in our base rebuild list PLUS the modifications detailed below.
 
The higher performing 2300cc, and 2450cc engines will operate fine with the original, unmodified fuel injection system, however our largest offering, the 2700cc requires our electronic fuel injection system to replace the outdated Digifant system. This "plug 'n' play" upgrade further improves performance of all our engines already on the road.
 
We have fine-tuned the camshaft profiles and compression ratios of all our engines. Our base 2200cc engine is safe to run on regular 87 octane, the 2300cc requires middle grade 89 octane, while the 2450cc and 2700cc engines require premium 91 octane. Please note: We recommend 91 octane fuel for all of our engines just as a matter of precaution. If for some reason your engine experiences a momentary over-heating episode, the extra octane may very well save your behind. Additionally, at current prices for gasoline per gallon, the price difference between regular fuel and premium has never been lower as a percentage.
