Ive thought about that but the cost of legally doing that here in Japan, the price is crazy. Have to go thru special registration, cost of having it put in, wiring, and pay extra money and have it re-inspected, etc. Also my road tax will almost triple.
The shop I spoke with about tuning the car once I decide what to do, suggested a 2.4 litre kit with a rb26 crank.
So I might just go 320-350 hp, and see how that is. If I want more than I will research more and maybe do the 2.4 litre kit.
Also I wasn't planning to buy a larger throttle body. I see them often over here on the car parts sites for the rb engines so I was wondering if anyone actually changed theirs.
