All the turbo's have coscast heads as standard. IIRC only the astra gte's have them n/a | |

The engines are identical, although your not going to get a coscast head on a cavy. The exhaust manifolds are different i think, although finding a new one isn't hard (i have a astra gte 16v manifold in my garden! LOL) The looms are the same except for the length, due to different engine bay sizes and ecu positions. | |

Are there any disadvantages for using a cav gsi as a donor rather than the astra. |
