Budget
Replacing the engine is never fun and is almost always expensive. Deciding on a reconditioned or remanufactured or crate engine may be based solely on budget. However, if you've got some time and some flexibility in the budget, you can upgrade while replacing. Reconditioned engines can be cheaper, but they also can have shorter limited warranties and additional components. Remanufactured engines can come ready to install with customized upgrades, based on how hard you use your Jeep and what you're trying to achieve.

These high-quality engines have been reverse engineered. All Spartan remanufactured engines including blocks, cranks and heads are machined and tested.

Short Block vs. Long Block
Short block engines are incomplete. Depending on the model, they may require additional parts including cylinder heads, gaskets and an oil pump. Buying and installing individual components can be costly and time-consuming. Long blocks can be bolted to the short block and are almost complete. Engine performance can be affected by the introduction of several individual external components. Since long blocks come with more parts, potential performance is better.
