Just something that's been on my mind.

I can't justify the expense of upgrading to a larger airbox like a radius fab etc(yet), so I've been doing a little research on how else to open it up. Saw mentions of an FJ80/LX450 airbox lid with the larger opening and thought I'd pair it with new 3" silicone that goes all the way down to the factory ct26 which I think is around a 3" opening? Have you done it? Any good results? Sounds like it could yield a little as the factory intake pipe is so restrictive down toward the bend.

I'm keeping things stock for the most part(except for a 3" exhaust) until I decide to go bigger turbo and intercooler, and my hands are itching of something to do. Appreciate all the pointers in advance
 
It’s defiantly doable however I’d do it at the same time I do the turbo.

I’d live with it now and save up for a big turbo and intercooler. And some water meth.
