After many years of testing, we are very excited to offer you our ultimate waterboxer option: The 2700.

Our 2700 has run in the 24 Hours of LeMons endurance road racing events six times, even driving to and from the event on one occasion. It has also run the NORRA Mexican 1000, a 1250-1400 miles off-road rally that runs the length of the Baja peninsula, four times. We got class wins in both events. Not only did the 2700 perform flawlessly during the entirety of all four, for the 50th anniversary of the NORRA Baja rally it propelled the van four hundred miles from Los Osos to the starting line in Ensenada, as well as the 1400+ miles back to Los Osos from the finish line at Cabo! Indeed, we have tried to break this engine in every way we possibly could and failed miserably! We are confident in its longevity and reliability.

GoWesty 2700cc high output engine power specs:
• 10:1 compression, with 162 hp & 197 ft-lbs of torque when fitted with our GW-EFI.
• 80% more HP and 82% more torque (area under the torque curve) than the original VW 2100cc engine.

You get everything included in the "Engine Specs tab" plus the following:
• Brand new billet steel, fully counter-weighted crankshaft with 84.5mm stroke
• Engine block and heads specially modified to accept the larger stroke crankshaft and larger bore cylinders
• Porsche piston-cooling oil jets ("squirters")
• Brand new, forged connecting rod set with new ARP bolts
• Custom made in USA 100.75mm forged and coated JE brand pistons
• Custom made in USA 100.75mm steel cylinders
• Proprietary camshaft grind specifically for this engine
• Larger intake & exhaust valves
• CNC ported intake & exhaust ports
• Brand new 1.25:1 ratio rocker arms
• Brand new OEM type oil cooler

Mandatory requirements for operation and full warranty coverage:
• GoWesty Engine Management System (GW-EFI)
• 91 Octane fuel - minimum*

*GoWesty recommends the highest octane you can get, even if your engine is rated to operate on a lower octane. The 2700cc MUST have 91 octane minimum. The other engines can run lower octane. It can NEVER hurt to use fuel of a higher octane than the minimum recommended, whereas using a lower octane can cause catastrophic engine failure. Fuel is all so expensive now, and the percent difference in cost between the lowest and highest octane is almost insignificant. Bottom line: It just does not make sense to use the lower octane stuff!

Break-In Guidelines: All Waterboxer Engines

Shipping: These engines ship truck freight only. The closer the destination address is to our facility in California, the lower the freight cost will be. If a forklift/loading dock is available, please choose the freight option without a lift-gate. If a forklift is NOT available, please choose the option requesting a lift-gate. If the wrong freight option is chosen, a surcharge of up to $95 for a lift-gate truck will be added to the shipping cost. Please check with your local installer prior to completing your online order. In addition, there is a residential delivery surcharge of $100.

As of May 2023, return freight will be charged separately when you are ready to return your engine core to GoWesty.

Core exchange: $1500 CORE CHARGE POLICY: Our engines are sold on an exchange basis. We expect an engine like the one you purchased to be traded in. For instance, you cannot trade in a 1.9-liter waterboxer core and purchase a 2.1-liter engine and expect the entire $1500 core deposit back. We deduct the following amounts from the core charge refund: Engine cases: $750, or part thereof for repairs as needed. Head studs: $50 per stud to a maximum of $750. Crankshaft: $250. Rods: $50/each (and so on with each component). So, for example, if your engine cases are no good (i.e.: too badly pitted), but the rest of the parts are OK, you will receive a refund of $250. If everything is in good shape, except all head studs have to be replaced, you will get $250 back. Or, if you send in no core at all, you will forfeit your entire $1500 core deposit. Read our Core Return Worksheet.

To return your core, please visit our return portal. Enter your order number and postal code, and choose core return to receive an RMA and return instructions.

Warranty: 48 month, 48,000 mile (whichever comes first) written warranty at no charge. We also offer Engine Warranty Upgrades for additional coverage. Please see the chart below for information, and click here to read the entire text of our warranty. This engine requires the GoWesty Engine Management System (GW-EFI) and 91 octane fuel. The warranty does not cover internal damage to the engine due to detonation damage, which could be caused by Digifant fuel injection, and/or as a result of using poor quality fuel.

IMPORTANT NOTE: Engine failure due to Digifant EFI, low-octane fuel, improper installation, overheating, incorrect timing, insufficient oil, contaminated oil, oil additives, outright abuse, etc., will not be honored by warranty. GoWesty strongly recommends replacing your entire cooling system—this engine is not warrantied against damage resulting from overheating. Please read this article for more information.
