B20 Header

Anyone know who and where have made that kinda header?

Primary and secondary tubes are both hair over 41mm OD. :doh:

Is it too small with 40DHLAs and R-cam?

Primary tubes arent even nearly same lenght :shock:

How much HP you can get with so small pri/sec tubes?

Yes its 2 litre. Need to make new collector because its missing.

Any succestions how long should be from head to the collectors smallest part?

My plan is to make collector from two 42mm 60deg angle pieces so that its like 2x42mm in 1x50mm out and right after that about 150mm long cone from 50mm to 2.5"?

Im happy if it can handle 150hp in the future so i think 41mm pri/sec is okey?

Tube ares is slightly bigger that exhaus port so that should not be too small for my plans?
