    please put info up for this, cos it sounds ridiculous to me.......




    i always thought the real reason for the reverse head design was packaging. they could fit the engine lower & further back . I also thought the cams were redesigned so the inlet ports became the exhaust & vice versa as opposed to turning the head round..

    Hmm, I know someone who has a Swindon Race Engine in a Astra Mk3 GSi. Might have to go take a look see which way round the head is

    The re-engineering to turn the head around was immense. It really isnt within anyones scope tbh to carry it out.

    Look at a pic of a reversed Swindon XE motor & you will see that the spark plug cover faces the wrong way etc. Cams are small thing in the grand scheme of things.

    ^ agreed re- Cams.

    The dizzy hole is blanked off, and replicated in the other end IIRC aswell

    I knew i had some pictures somewhere, this is a Swindon XE Engine, albeit not a "proper" BTCC item, however it was used in a privaters BTCC car

    those photos /\/\/\ don't show a reversed head design. I think that motor was from the national saloon championship, where they could use a super tourer shell, but a stock based engine.

    I found this one on a super touring site, it appears to be reverse head, but the top of the head seems the same way round as a stock one.

    I guess they can run them lower as they will be using dry sumps thats why the exhaust would want to be fitted that way.

    Yup, it has to be run the same way around for obvious reasons (the pulley is on the left). Its basically a re engineered head to allow the inlet to fit to the front and the exhaust to the back. In laymens terms all that needs doing then is essentially reverse the cam timing :D Not that its as easy as that
