ok i have a b16a2... i think well i bought it and the vin was filed off... yes i know why and all.. but all it says is b16a then its filed ... it has a couple of numbers on the back of the block and im wondering if there is a way to tell if those say what motor it is and also i got the stock ecu and it still has the sticker with a vin but i dont know how to check if it goes to a b16a2 or not... just let me know if you have any thing to help me... thanks
