difference between 1,6 90hp head and 1,4 xsi head?

  1. #1
    Is there any difference between these two heads? I'm byuing a cheap 90hp engine soon and got a 1,4 xsi head. Is it only the cam and ecu that is different?

    The XSi has the more powerful engine (100bhp if its a pre-cat!) the cam is slightly better and the rev limit is higher and fuelling is different... remember the XSi is originally a 1.4 engine so the power is not coming from the bottom end! lol... If you put the XSi head on the 1.6 bottom end and run the VTR loom you will gain next to nothing!... AXgti and XSi 1.6 conversions run roughly 110bhp because alot of it is the way the ECU runs the engine as the VTR is designed to return a better MPG hence the shit gearbox!

    I know the vtr ecu and cam are shit, but i'm using 1,3 rallye ecu and loom. together with 1,3 rallye inlet manifold and 1,6 xsi or rallye chip. And sooner a remap.
