Even a tubular manifold with very short runners, unequal length, but with a very nice merge collector is better than a log. Anything to merge the exhaust flow as smooth and as fast as possible is the best.
Has anyone tested the 20V cams on a turbo motor? Seeing how they seem to make the most low end power NA, they should make a lot of power and spool the turbo very fast on a turbo setup. I have only ever seen VET turbo setups with standard sr20ve cams and sr16ve cams and would be interested to see the comparison with the 2002 sr20ve cams.

yeah a guy down hear is
he made 300rwkw's on 12psi with a 2.2litre on 98 ron which is a stupid figure by our standards, car runs a gt3076r .63 t3 flange
this was also just the run in tune so its quite limited tunning wise, but is stll making more than most det's do with the same turbo at 20psi on our dynos with our fuel. car will have another 1000rpm put into it and 10 more psi later on when everything is sorted.
dyno is about half way down

the 20v's have a lot more overlap on high lobes 57 deg i think it is, however i have spoken quite a bit with the guy who had a lot to do with the build up of this car and he said he tuned a lot of the overlap out, i dont know if that ment he *stuffed up* the cam timing on the low lobes. Would actually like to see a degree card for the 20v's
