    Inlet was off a C16nz, it has a egr valve too but i just blanked the port with some alloy plate.
    Yeah the injectors are slightly different.

    My spi engine wouldn't run with a ast2 cam fitted

    86hp was on a 1.4i, with a SRi cylinder head, home modded 1.3sr inlet manifold,1.6spi throttle body,gte cam, decat/4-1 manifold and ashley exhaust system.

    60-65 BHP from your old 1.2i engine ? Not bad

    I'm thinking about a Cam for mine, so one from an SRi or GSi would do ?

    What kind of gains would that give me ?

    Engine has had a full service and also has an induction kit fitted

    1.4sr cam is best. If not then a gte/gsi one.

    Cam
    De-cat
    Std 4-2-1 gte/gsi/sri exh manifold and downpipe, and decent exhaust system

    Should see about 60hp, and could be done for about £50

    Doesn't it need a Cat for the MOT ?

    Would probably have a full custom exhaust system made and get it as freeflow and legal as possible

    Cheers for the help Adam

    Just a quick question can the 1.4 or 1.6 head be fitted to lower the compression ratio for a turbo application? and could you run a GTE loom and ecu on a 1.2 engine that had been turbo'd??
