new cast manifolds for kkk26's

i need a little help here please, have some manifolds which have been modified to fit the head of a mkiv made by trust originaly.

now the manifolds allow kkk26's to fit and probably other makes of turbo to if you get flange's made for different fitments.

 

my ? is, this system doesnt have a balance pipe btween the manifolds so each bank of manifolds are seperate, every other set of manifolds ive seen have a balance pipe off the same pipe that feeds the wastegates.

 

i am aware that this would equal the presure out btween the two manifolds but does that not effect the true reading the adjustable wastegate see's ? ie exhaust gases traveling from one manifold to the other and causing exhaust gas turbalance.

 

also is it ok to fit the wastegate dump pipes into the down pipe's ? and is it ok to have both dump pipes into the same down pipe as it will make plumbing so much easier.

 

can someone measure the distance from the edge of the head on the exhaust side being the edge of rocker cover to the suspension strut leg so i can make sure all will fit in.

 

hopefully having some copies made of the manifolds when finalization is finished.

 

thanks in advanced.
