    Wow I didn't think it would make that much difference.

    Burgo well said, the 1.2 cam must be absolutely flat lmfao

    there seems to be a lot of info on tuning these1.2 8v engines but who here has actually done it

    and what have you done what are your experiences with tuning the 1.2's

    did you notice a big difference or is this thread a observation on what can be done to a 1.2 and not actually been carried out by any one

    Yer we could do with some recomendations and opinions rather than a compatibility list.

    yer that's what i mean i would love to see a dyno print of all this on a 1.2 might have to do it one day when I'm a bit more flush


    i know its not going to lead to massive gains but still would like to see just how much extra performance you can get for under 200 quid

    Many years ago I had a 1.2 with a 36mm weber carb, 1.3 camshaft and SR exhaust manifold with a home-made single box system which ended up with 60bhp, the same as a 1.4spi. Unfortunately I never got a print-out of it though.

    Lexmaul used to do a kit for the 1.2 that basicly included the 1.3 exhaust manifold and system, with their own camshaft with some other bits (can't remember what) and quoted 80bhp when set-up.

    Arragorn who some members may remember applied similar ideas to a 1.2spi (gte cam, exhaust system, 1.4spi injector) and I think that managed to hit 75bhp.

    tbh I wouldn't mind another one just to see what I could get out of it.

    I fancy trying some things out (SR Cam for example, and I'll probably mate a GTE manifold & downpipe to Eurorallye system at some point too)

    So if i went to my local BMS and got a 1.3 cam for my 1.2 carb it will go straight on and gain me 5bhp [ YO! ]??

    How easy is it to change.

    I have all the bits to build a nice 1.2 spec, i just havent got around to doing it yet. My 1.2 already has a GTe exhaust system, and in the barn I have a 1.4SR cam, 1.3 inlet manifold and a 32/34 weber carb. I just need the jets to have all the bits complete. When I do it ill post my findings on here.
