    Why Choose a MAP-built Stage 1 Engine?

    MAPerformance believes that the heart and soul of any motorsports project is the engine that powers it. Since inception, MAPerformance has combined the highest quality components with the most stringent industry standards to produce world record setting results. MAPerformance utilizes proprietary specifications combined with years of experience in each engine that is assembled.

    We thoroughly inspect, clean, blueprint, and assemble our engines in a sterile room and all machining operations are carefully scrutinized to ensure all aspects of every operation meets or exceeds our own stringent requirements. From the weekend warrior to the all out race car, MAPerformance has an engine option to suit your needs.

    Don't know exactly what you need? MAPerformance has the expert guidance to assist you in choosing and top rated customer support to assist you with your long term project goals.

    Please Note: This product is built to order. Based on fluctuations in demand build times may vary throughout the year. Please contact an MAP sales representative for current estimations. MAP engines also have a specific break-in process we suggest you follow to ensure your engine sees a long life!

    Please Note: You must supply your own core and you must supply BOTH a 2.0 4G63 block AND a 100mm Crank.

    The 2.3L configuration utilizes a 100mm crankshaft within the 2.0L block to increase displacement. The wristpin location must be moved up 6mm to accommodate for the additional stroke, but this is the original 4g63 stroker so stock on these pistons is rarely an issue!

    Features

    • Hot tanking/degreasing
    • Iron block engines are then baked
    • Blocks are shot peened or media blasted
    • Gasket surfaces are flat sanded
    • Oil and Freeze plugs removed
    • Balance shaft oil feed is drilled, tapped and capped

    • Blocks are machined to stringent in house specifications
    • Block is reassembled with oil plugs and new freeze plugs
    • Block is hot tanked for final cleaning High temp primer and paint process is applied
    • Customer specified components assembled into block

    MAP takes the following steps to ensure the highest quality finished product

    • Thorough inspection and measurements are taken MAP will not use a crank that requires cutting steps to prepare the bearing surfaces
    • Sludge traps are removed for cleaning then drilled & tapped for installation of serviceable fittings
    • Cranks are hot tanked, degreased and then precision micro balanced and polished

    Customer Supplied Core
    You will be responsible for packaging and freight cost of your engine. Please do not ship us an engine that needs to be disassembled. We will only need your block, crank, and main caps. **If you have a good block to send in, but no crank (or vice versa), please reach out to us to determine accurate pricing.
