ok guys,
i'm planning to build top mount manifold for my 9:1, 84mm b18 with divided t4 gt35r on pro1 cams and i'm thinkig what size pipe diameter do i need - 40,42,45,48mm ? (inner);
and one more- i want do only one WG, can i do it on long tube, that will connect right before WG? will that make some kind of peeks in TQ or something ?

 

nobody?

 

what size wg to you plan on running? and i would plan on having the wg right at the collector where all four tubes converge... try to ensure the tubes are the same length as to equal out the distribution of gas out of the cylinders

 

if i do one WG i plan to go with 44mm

 

can somebody messure it or know what he own ?

 

you should have this moved to the welding fabrication section as you will get alot more feedback.

 

ok, THX, i'll do that
