BNR S1 turbo kit
Great fitment, spool a lot quicker than stock, felt more power even without tune, can't wait to get it tuned! Only complain is the studs it came with is a M10x1.5 which stock is M10x1.25, and I have to find new exhaust nuts for it(didn't come with it), but overall great affordable upgrade!
