I have nothing really useful to say to be honest, but I'll make it less than a one-way conversation to say the least
Parts are beautiful. I'm so jealous lol. I'd be so on that if I had a 6MT. Just doesn't feel worth my time on a 5AT, especially with the extra drivetrain loss.
ssjoeboe9 has a stage 2 setup with aftercooler, and he's currently e-tuning with Vit. I'm not sure how active he is here, but he's definitely active on azine.
From what I've gathered, you MIGHT need a new intake if you don't have one already, as the forced induction may collapse/flex the stock airbox. I think Joe has a custom (low-budget) metal tube design, much like the Takeda or other metal tube intakes. You'll need the PCD and test pipe for sure (which I believe you already have) because the exhaust restrictions on the stage 2 setup are enormous. For now, I think he's still on the stock catback. I don't think Vit has complained about that being a real restriction yet. You'll also need Hondata for tuning if you don't already have it (Vit will likely have one for sale anyway), and it'll be highly recommended you get a wideband sensor to track your AFR in case you're about to blow up
He also had belt slip issues, but I don't recall the actual solution. Vit had to pause his e-tune until he fixed it. He may have gotten a new and different sized belt altogether.
I know this is the tsxclub forum, and we really shouldn't be referring to other/competitor forums. But if you want more information, I can PM you his build thread on azine. It may save you some head/heart aches down the road.
Good luck obert!
