Performance Engines

UMR Engines can build your modified engine with forged pistons, stroker kit, full engine balance, aluminium cylinder heads, we can also

port and polish your cylinder head. If its horsepower HP or KW you are after look no further. UMR Engines has been building performance

& stock engines since 1975. UMR’s performance machine shop can handle all your requirements. Our shop is located at 7 Moss Street,

Slacks Creek - Brisbane. Our shop opening hours are from Monday to Friday 8am to 5pm

Performance V8 Engine Rebuild / Reconditioning Brisbane
UMR Engines can fully race prepare your engine to suit your custom requirements. UMR offers custom built heads from slightly modified street to full race heads. At UMR we can build a head ensuring you receive the best possible performance available without blowing your budget. We will match your valves, springs, collets and retainers to the selected camshaft. We blue print your spring tensions to suit the cam specs to ensure trouble free performance eliminating coil bind or valve bounce. UMR performance heads are ultrasonically and chemically cleaned, crack tested and pressure tested for suitability. At UMR Engines we calculate the engine compression and machine the required amount off the head face. UMR engines have a Berco head mill running CBN tooling on a Winfield jig allowing accurate 4 point set up and very accurate finishes. Accurately machining 010", 020", 030", 040" or 050" off  alloy or cast iron heads while still maintaining the perfect finish to ensure a perfect seal and long life of your head gasket. Multi angle valve seats and valve faces ensure ultimate performance and air flow. Valve guide fitting, valve seat inserting, screw in studs, are all part of UMR's reconditioning service. Your race prepared block will be chemically cleaned and inspected for faults and suitability for machining. Camshaft bearings, Welch plugs and oil gallery plugs will be removed. The main tunnels will be tensioned to specs and measured for size. Main cap stud kits can be supplied and fitted if required. Cylinders will be individually bored 0025" short of the finished size to allow adequate cross hatch honing to achieve the optimum ring to bore seal. New cam bearings will be fitted and checked for correct clearance of new camshaft. All rotating engine components require balancing to ensure vibration free performance, durability and maximum performance. (balancer, pistons, rods, flywheel, pressure plate, crankshaft)Con rods will be measured for size, replaced or closed and honed to suit required specifications. Pistons will be assembled to con rods and checked for alignment. Ring gaps checked and adjusted to suit use and fuel. If a specific compression ratio is being achieved a dummy assembly and cc measurements will be needed for the compression calculator. Head gasket selection and block face machining will achieve the compression ratio required. Final washing involves a through clean of all components with particular attention using hot soapy water in the bores.( see final wash procedure on http://engineproblem.com.au/procedures/details/5/7.html ) Engine assembly is very critical to the overall performance of the engine and requires many procedures to ensure the best outcomes.
