if you dont change the pistons, the compression ration will be lower & cause the engine not to run as well as it should as its N/A & not forced induction. | |

what difference does it make putting a mpi head on it then? could you also put a mild cam in the mpi head and get a decent power increase??? | |

i used a 1.4sri 8v head on my SPi engine, kinda helped torque a bit & top-end power, but was still running the SPi setup... :| | |

The head design is also different, in the ports and valves are larger. | |

compression ratio of the SPi is lower than the MPi so the pistons are different... the poskets are deeper on the SPi to lower the compression. | |

Get full head and manifolds off the mpi, and the pump, fuel connectors etc. | |
