This is great, congratulations man! Glad that you have awakened the true potential of the car
How does it sound though? Any different at start up or when you’re on the road? You don’t have an exhaust setup but maybe it’s time to think about it.. Maybe resonator delete? Would definitely bring out the burbles way more... I’m contemplating getting my mufflers reinstalled and then removing my resonator.. And then I’m gonna put in my DP and call it a day for the exhaust setup.
But yeah, real interested how it sounds with JB4.. because with BM3 this thing does not sound like any of the other inline 4’s or even the N20, it sounds really good for a 4 banger IMO
