Does anyone know for definate, or could someone post a link, to settle an arguement please.

 

Is there a difference between N/A a TT camshafts? As I believe that there is'nt, infact, from what I remember, N/A and TT heads are exactley the same, except when you actually get inside the ports, then you see that the ports are different internally. The cams, the valves, the port sizes are the same.

 

Thanks guys.

yes matey there is a difference.. ive got both in the garage and there is a big change! the TT has a longer lobe!

This may help :-

Thanks Andy, duration is different then.

That is between auto and 'other'. Not 100% certain that 'other' includes NA. There may be a separate manual for NA's but I've never seen it.

I take that back, the manual does seem to include the NA.
