So I messed up not only once but twice by hesitating on buying a NX plate kit from AM while they had it for sale on black Friday and then when it was on clearance. I went to buy one the other day and they were no longer available. Well I've decided that my car has to have N20. I found it for a decent price (about $500) at this Blowby Racing place but ive never heard of them and honestly everywhere else I look ( Jegs , Summit , ect.) its way to expensive. Like almost $700 or more for the kit. I also have a chance to buy the service manager @ my dealerships old used NOS kit for $275. But im leery of buying a used kit. What do you guys think ? Im open to any comments or suggestions here.
