    some questions

    Frequently Asked Questions

    A rebuilt engine is the same as a remanufactured engine. Think of it as the equivalent to a brand-new engine with the same horsepower as the original engine. Remanufactured engines start with an old/used engine that is no longer performing according to original design. The engine goes through an in-depth refurbishing process which includes machining of reusable components (such as an engine block), cylinder heads, crankshaft, and the replacement of critical components that had suffered the most wear and tear during the life of an engine. This can include pistons, rings, bearings, oil pump and others.

    Rebuilding an engine can take anywhere from 4 to 8 business days, if all required new parts are readily available and do not require special order. Reina Rebuild keeps an inventory of the most common engines to minimize downtime for customers and allow them the option to have immediate access to a new engine.

    Reina Rebuilds specializes in large (V6, V8, and V10) gas engines for GMC, Chevrolet, Ford, Dodge, Chrysler and Jeep vehicles.

    Reina Rebuilds offers engine installation services in the Phoenix, AZ metropolitan area. In addition, we have a network of partner mechanics in other cities within the state of Arizona. We would be glad to get you in touch with the right installer.
