Dyno Plot : Low boost S mode 1.15 bar, Hi boost S# mode 1.45 bar Picture of the car : So it has been awhile since I updated on NASIOC but I'd like to introduce few of the cars I encountered over my subaru journey. Car is my client's 2014 JDM STi GVB Spec C. This car features many desirable options such as lightweight glass, aluminium hood, intercooler spray, etc. We decided to ditched Spec C ball bearing twin scroll setup for UEL rumble + sufficient power on top-end setup. I was personally against on ditching twin scroll setup but ever since owner bought the car brand new in Osaka, Japan, he wanted to get that signature Subaru rumble sound on his beloved Spec C. Goal was to keep the response of twin scroll ball bearing character but provide sufficient top-end. Gas was RON 99 (93 equivalent in US) Insta link for more photos : https://www.instagram.com/p/CZ4W-B7FNdd/?utm_medium=copy_link Enjoy.

Nice to see this here. I'm putting together a similar build but with an EJ257 and TD06SL2 on the exhaust side of the turbo.

Ah, I've already bought the turbo with the TD06SL2, I wasn't sure what the TF06 was exactly. Seems like plenty of people have made good power with the SL2 though. Good to know.
