Engine Internals

About Engine Internals

Careful selection of Performance Engine Internal tuning modifications can lift an engine from a docile supermarket cruiser to ¼ mile drag monster.

While it is tempting to throw in every modification you can, it's worth noting that they don't always work well together.

i.e: a gas flowed head with a sports cam produces less power than it would with just one of the two modifications if the cam profile is not carefully matched to the head flow rate.

When modifying your engine internals you want to avoid ending up with a high BHP engine that has an unusable low torque output!

JBS supply performance engine internals such as:

  • Low compression Pistons 
  • Performance Rods
  • Valves
  • Balanced Crank
  • Bearing girdles 
  • Studs and Fixings

Our online expert will be happy to help you make the best selection for your specification and budget.
