Hi all,
Thanks for the replies.
I'm not looking to overcomplicate matters, just fore arm so to speak.
I understand that the fuelling self regulates, but I am a little surprised that the throttle bodies and/or the MAF's are not a different size. The jump from 2.6 to 3.2 is more than a 20% increase in capacity and I would have thought that might have been reflected in the size of something. Thinking about carb venturi sizes and how they used to go up with higher capacity engines, sometimes quite markedly. Perhaps it is more a matter of making a single throttle body that can flow sufficient for all the engines in the range?
More than anything, If I do this change I want to yield all the extra power that appears on paper and not limit the output by overlooking some small detail.
Of course, I'm not a racer and the Omega is far from a sports car but the 3.2's I have driven were a fair bit spritelier than the 2.6. Had I been able to find a 3.2 worth the money I would have gone for it, but I bought on condition mainly. It's also a fun project and I like the idea! Anyway, I've bought an engine hoist now so I suppose I'd better do it.
Regards,
Graham.
