KORacing Products » Toyota MR2 MK2 » Engine Builds

The next level in 3SGTE engine building. Just like the KO Racing Super Stock engine, the KO Racing Black Works engine uses all premium rebuild products, forged pistons, new bronze freeze plugs, etc., but takes the head work a bit farther with proprietary modifications to the chamber, and ports to create a high flow, power making engine. Black Top spec. engines have made in excess of 400whp on pump gas with other supporting modifications. All of these spec engines use 3SGTE short blocks regardless of stroker crank, or stock crankshaft.

At KO Racing, we've been building 3SGTE engines for almost 10 years, and are only now offering this service publicly in 2011 because we are now comfortable we can produce a reliable, well built engine package for the MR2 and Celica turbo enthusiast. Complete from the valve cover to the oil pan, bolt on your accessories, intake and exhaust manifolds, turbo, transmission and let 'er rip!

  • 1mm oversized intake and exhaust valves
  • Brian Crower valve springs
  • Shimless buckets for valve lash adjustment
  • ACL race bearings
  • Moderate port smoothing, and modification for improved flow
  • Smoothed and modified combustion chambers
  • 400 grit lapped head and block surfaces (trues surfaces with extremely fine finish for metal head gasket)
  • CP or JE or Arias Forged pistons (+.020" overbore typically)
  • Total Seal custom high tension piston rings
  • Manley or Pauter Rods
  • Cometic head gasket
  • Micropolished crankshaft
  • Balanced rotating assembly
  • New valve stem seals
  • New Toyota high volume oil pump
  • New Toyota water pump
  • New Toyota timing belt and tensioner
  • ARP head studs
  • ARP Main studs
  • Socket head valve cover bolt kit
  • New Toyota engine overhaul gasket set
  • Signature KO Racing engraved black wrinkle finish valve cover
NOTE: A core engine is required for this rebuild service

NOTE: it is assumed that the core engine did not have a rod bearing or similar type failure. If it is a rod bearing failure motor as the core, additional charges will need to be paid for a new oil pan, oil cooler, and pickup tube. These parts can sometimes be obtained in good used condition, but if not, a new oil cooler MSRP from Toyota is nearly $800. Reusing an oil cooler from an engine that is known to have had a rod bearing failure, or oil pan (gen2) from the same will result in nearly immediate demise of a freshly rebuilt motor. We check all oil coolers prior to installing for metal debris inside if supplied by the customer.

NOTE: Motor is provided with a warranty against defects in workmanship. No mileage or time based warranty offered unless installed by KO Racing, and the engine is broken in by KO Racing. Component level warranty are from the manufacturer only. KO Racing cannot be held liable for any incidental damage or additional cost incurred due to a part, or engine failure.

NOTE: Core Exchange is typically required, though we have a few cores we can provide on an exchange basis to limit downtime.
