Experienced engine builders/tuners are aware of the exponential increase of internal loads when engines are tuned to produce more power. The answer is to upgrade your engine with an Atomic “Bulletproof” engine rebuild kit before a costly engine explosion takes place.

Although it is impossible to predict an exact point at which component failure will occur, many Ford experts agree that 275- 300 RWKW (350-400HP) is definitely entering the danger zone for the DOHC engines, so before the damage is done and you are up for a whole new engine, cast an eye over our range of bullet-proof bottom end rebuild kits.

Utilizing exactly the same componentry as fitted to our record-setting engines, Atomic rebuild kits are ideal to upgrade Ford Barra 6-cylinder engines to handle big power increases. Available in two configurations (Phase 1 or Phase 2) they comprise the following:
