Turbos on a slant
if you daisy chain them youll feed the 2nd with potentially frothed oil, run a 3 port manifold and feed each its own. Just jet each oil feed to provide the minimum the turbo needs so you dont bleed off all your engines oil pressure. Holset HX40 required 2l per minute. and 10 psi min. just for published data sake. Not sure what a muh smaller cartridge 22mm would take. Where you at in CA?
