i have also heard that they respond well to the fitting of tubular manifolds but not had first hand experience of this
yep your right mate pistons , rods ,crank , ported and polished cylinder heads etc but ive heard that it runs close to 450bhp n/a at high revs (9500) and is now detuned to 300bhp at 7500 rpm and thats why the pistons , rods , and crank were fitted but cosworth say that the standard bottom end is ok for 350bhp as i know people who have low boost turbo set ups running 350bhp
