Description

Experienced engine builders/tuners are aware of the exponential increases of internal loads when engines are tuned to produce more power. The answer is to upgrade your engine with an Atomic Engine Rebuild Kit before a costly engine explosion takes place and renders the block, crank, head, etc useless.

Although it is impossible to predict an exact point at which component failure will occur, many Ford experts agree that 300-350 RWKW (400-460HP) is definitely entering the danger zone for the DOHC engines on Premium 98. Running E85 can see higher figures (another 50 or so RWKW), however engines do not last at these power levels. We see broken conrods and smashed ring lands at these power levels on a regular basis.

And having rebuilt over 500 Barra engines since 2004, we have seen a lot of catastrophic failures!

So before the damage is done and you are up for a whole new engine, cast an eye over our range of Engine Rebuild kits. Catering to mild rebuilds all the way to 1000+ HP monsters, Atomic Rebuild kits utilize exactly the same componentry as fitted to our record setting engines, making our range of rebuild kits ideal to upgrade Ford SOHC/DOHC 6 cylinder engines to handle big power increases.

Available in two configurations (Phase 1 or Phase 2) and various power levels, they comprise the following:

Phase 1 Rebuild Kits

  • Atomic billet conrods - either StreeTorquer (550 kW rated), Superleggera (698kW rated) or FatRods (998kW rated), which come with pressurized oil feed to gudgeon pin bushes to provide gudgeon pin lubrication and piston crown cooling – an Atomic exclusive!
  • Atomic Hypereutectic, Atomic Forged or Cosworth F1 Series forged pistons with coated skirts, pressure fed gudgeon pins and Chrome Steel turbo rings.
