Hello there,

Because of my particular turbo/intercooler position in engine bay I was planning to build myself a turbo mainfold for a B16 engine swapped in another car.

Can anyone tell me the correct pipe diameter and lengths for the best performace ? My goal is to reach 600hp at crank for drag race.

Somewhere I read that usually people use 1.5" pipes with 15" of length from head flange to turbo flange.

Any help will be appreciated.

Regards

Silvio

 

No one knows nothing about this?

No one have never measured diameter of pipes of your mainfolds ? For example full-race, ss-autochrome, ecc. ecc.
?
