Holset Turbo HX40W Input

[4g63tcrazy]

The drain tube must be 19mm ID minimum (Might have been 16mm, cant quite remember). So your basically looking at a 1" drain line.. You also must have 10psi of oil pressure at the turbo at idle, 30psi during spool-up and no more then 80psi WOT. Follow those specs and your Holset will last forever.
