  • [Corsa B 1993-2000] 1.6 16v head on 1.4 16v block

    As above, putting the 1600 head on my block. Do I still use a 1.4 head gasket?

    Will I see any gains? And what will it do to the compression as I was going to get the head skimmed a fair bit to raise compression.

    Does anyone know where I can get a commetic head gasket?

    The heads are identical (almost), I believe you could use either the 14 or 16 headgasket, it wouldnt matter. The cams are different, thats the biggest change. That and 16 heads are reported to have larger inlet ports. They're pretty much like for like swap in almost all cases.

    Gains? If you used the 1.6 cams aswell, then yes I'd expect you'd see some gains, but nothing ground breaking

    Cometic gasket for x14/16? Cometic sell through dealers... These people -> Cometic Gaskets - Co-ordSport Performance and Tuning Parts have one listed for the Opel 1.6 16v and are UK based, contact them

        the heads themselves are pretty good, lotus did them. port match it to your manifold, and thats about it. ther eis a thread somewhere that compares c16xe, x16xe and x16xel heads. apparently the best was the xel one....

          I wouldn't port the X16XE head if the ports as standard are already larger than the X14XE head.
          Larger ports will increase peak BHP, but lose torque lower in the rev range.

          Rob, the XEL head is the same part number as the X14XE head IIRC. It uses triangular shaped ports according to some threads on mig and if you want to fit it an X16XE engine, you need to open the ports up more.

              Will it be okay to reuse my cambelt? As it was fitted only in June

                i always change the belt every time it comes of just for peace of mind, continental belts are only 25 quid give or take and id rather not take the risk of lunching the head.. but thats just me

                      euro car parts sell them as their standard replacement belt. they always seem a good quality and its a brand rather than an unbranded cheap ****. in answer to you question, I'm sure the autovaux belt will be a decent quality one.

                        Cheers guys. If autovaux is much more pricey I'll go for the continental.
