I'm looking to upgrade my Vanagon's engine. What kind of performance gains can I expect with the GoWesty 2300cc Engine Kit, and what are the minimum octane requirements?

The GoWesty 2300cc Engine Kit is designed to significantly boost your Vanagon's power. When paired with our GW-EFI system, you can expect around 114 horsepower and 157 ft.lbs of torque. This kit requires a minimum of 89 octane fuel. While 89 is the minimum, we strongly recommend using the highest octane fuel available to ensure engine longevity and prevent potential catastrophic failure. Investing in higher octane fuel is a small price to pay for the long-term health of your upgraded engine.

I'm comfortable doing some engine work myself. Does this 2300cc engine kit come with instructions and technical support for building it?

This 2300cc Engine Kit is intended for experienced builders with their own tools and mechanical knowledge. It does not include installation instructions, and GoWesty does not provide technical support during the engine building process. The kit involves precise machining adjustments to your engine case, which requires significant expertise. If you're not highly experienced with this type of detailed engine work and don't have the specialized tools, we highly recommend considering a complete, pre-assembled engine build instead.

I've heard about case machining with these kits. What exactly needs to be done to my engine case for the GoWesty 2300cc Engine Kit, and how critical is it?

The engine case (block) for the 2300cc kit requires specific hand-machining for clearance adjustments. This includes areas around the cylinder roof, piston at bottom dead center (BDC), and the head stud bosses. This is a critical step because no two engine cases are exactly alike. It's essential to have a highly experienced individual perform this work. Repeated test-fitting of the crankshaft, connecting rod, cylinder, and piston is crucial throughout the machining process to ensure proper fitment and function of the new engine components.

Is the GoWesty 2300cc Engine Kit emissions-legal? I live in California and need to pass smog.

Yes, the GoWesty 2300cc Engine Kit is emissions-legal. It has been issued a California Air Resources Board (CARB) Executive Order #D-786-3, which means it is compliant with smog regulations in all 50 states, including California.

Here is what you get with our 2300cc high output engine kit:

Counter-weighted 79.5mm stroke crankshaft
Camshaft with custom GoWesty profile
Reconditioned connecting rod set (mounted on crank with new bearings)
Custom cast Silv-O-Lite brand 96mm pistons with wrist pins, clips and rings
Torque plate-honed 96mm cylinders
GoWesty copper cylinder head gaskets
New hydraulic lifters

IMPORTANT NOTE: The engine block assembly (case) will need to be hand-machined for added clearance in several places, including (but not limited to) the roof and beneath piston at BDC and back side of the bosses into which the head studs install from the opposite side. The case is made from cast aluminum, and no two are exactly the same. There is no "blue print" or "program" to achieve this—it has to be done by hand by a very experienced and talented individual. Please read this article for more information. The crankshaft/rod assembly, cylinder, and piston must be test-fitted repeatedly to ensure that the clearance is correct and adequate, while at the same time not going too far and maintaining the cleanliness required for any successful engine rebuild.

NOTE: Kit does NOT include installation instructions, and we will not provide technical support throughout the building process. If you do not have the tools, experience, and/or know-how to build a water boxer engine, please purchase one of our complete engines.
