GoWesty 2450cc high output engine
*9.4:1 compression, with 110 hp & 150 ft.lbs of torque

You get everything included in our base engine (GVW-2200)
Plus the following:

• Counter-weighted crankshaft with 84.5mm stroke
• New forged connecting rod set with new ARP rod bolts
• Porsche piston-cooling oil jets ("squirters") installed (beginning 2/09)
Custom made in USA 96mm forged and coated JE brand pistons
• A exclusive proprietary camshaft grind specifically for this engine
• Requires 91 or higher octane fuel and will pass tail pipe emissions test **

**GoWesty recommends the highest octane you can get, even if your engine is rated to operate on a lower octane. The 2450cc 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!

Shipping: Freight costs are $300-1000 (including return of core) anywhere in the lower 48 states. These engines ship truck freight only. The closer the destination address is to our facility in California, the lower the freight cost will be. A freight quote will be generated by our staff after you have completed your online order. *NOTE* The delivery destination MUST have a forklift to get the engine crate off the truck. Please check with your local installer prior to completing your online order. If a forklift is not available, a surcharge of $190 ($95 each way) for a lift-gate truck will be added to the shipping cost. In addition, there is a residential delivery surcharge of $100.

Exchange: $1000 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 $1000 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 $1000 core deposit.

Warranty: 48 month, 48,000 mile (whichever comes first) written warranty at no charge. We now offer two engine warranty upgrades (see related items below)! Please see the chart below for information, and click here to read the entire text of our warranty. This engine requires 91 octane fuel. The warranty does not cover internal damage to the engine due to detonation damage, which could be caused as a result of using poor quality fuel.

IMPORTANT NOTE: Engine failure due to 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 warranted against damage resulting from overheating. Please read this article for more information.

This engine is internally modified to increase displacement and power output while maintaining original emissions levels. It is externally identical to the factory original 2100cc waterboxer and will pass all visual inspections and testing for smog-controlled vehicles. However, in order for a rebuilt engine to be officially legal* to sell for highway use in all 50 states, no modifications of any kind are allowed. Please check how your state laws apply to you before purchasing.

*This product is intended for off-road use only in the state of California.
