If your worried about excessive CR and it's just to move it you could disconnect the wastgate actuator and wire the lever arm so the wastgate is wide open all the time and use the standard head. Providing the turbo is all conncted for oil etc, it will just spin fairly slowly and develop no boost with the wastegate heldwide open. Schrödinger's cat - so which one am I ??? |

Sorry, what is cracked? The head or the block? I still don't get it. On 13th Jul, 2012 Ben H said:

if the compression isn't sky high and your fuelling and timing are good then it will be ok. If something is worth doing, it's worth doing half of. |

if it's only cracked through the very end around the stat housing, can it not be welded up? Mr. Prawn, the friendly Crustacean- slowly making steps towards forced induction. |

Paul - Carrots and broccoli on the side? Jam roly poly and custard for pudding? I think so. You could look for local bodyshops or metal fabricators who have oxy/acetylene equipment I seriously doubt it! |
