    I was told by an avid peugeot fan that fitting an xsi head to a vtr would raise the comp ratio and help it breath better? Is there any truth in this?

    People tend to do this to VTR's simply to get the 7200 rpm limiter.

    As the XSI/raylle heads use big bearing cams. Therefore, putting it on a mk1 vtr block.. Would be like sticking a ph2/3 cam in there.

    Raylle inets are ally, so a better induction roar, with the inlet being 3x bigger than the std VTR one.

    Would need head/loom/ecu etc.

    Quite abit of work to get it all set up tbh.

    If you have the spanner capability, then it usually works out cheaper than actually camming/remaping the vtr engine.

    And you will probs be looking at 110-120bhp, dependent on engines condition etc.

    Or just buy a raylle/xsi engine, to save joining 2 engines up.

    I was toying with this idea, that's why i know abit on it. Some guy on here, has actually done it to his VTR, and he says the gains are goooood
