karlp2 Member 81 Member For: 11y 3m 12d Gender: Male Location: Auckland, New Zealand Posted 25/07/18 07:21 PM Share Posted 25/07/18 07:21 PM Turbo upgrade, have a G6ET with a stock 3576 turbo with the porting and flapper mod, looking to upgrade to the GTX3582R Gen 2. When ordering I just want to make sure I’m getting everything needed, my questions 1) there’s a couple options around the flapper size and the actuator size - what is recommended? 2) Also reading through I understand I need a couple reducers but can’t see any details to guide me on what exactly I need to order? Current supporting mods: Walbro 400 pump, 1000cc injectors, P/W stage 1 intercooler, and a full xforce (twin 2.5”) exhaust.

I think you mean oil restrictors. The turbo supplier should be able to tell you what you need there for your motor and turbo combination and either supply them or tell you what specifically to buy.

You don't want an oil restrictor with that turbo. The turbo has a 4 inch inlet and a 2.5 inch outlet so you wanna plan your joiners around that. An intake/airbox upgrade is probably in order too, for various reasons. If anyone is interested to know, I could still make 10psi up top, with the actuator disconnected from the flapper, with pretty much the same setup.
