I'm possibly trading my gsr clone integra for a real 99 si. problem is the guy said it has a theft title and what not, so i checked it out and everything seemed to be there and not missing. till i checked the engine. b16a, so of course its a sir2 and its a jdm tranny i can tell cause of the no vin. but its code is SC4 not s4c but SC4. which after some searching i think is a b16b or b16a third gen lsd transmission. But i can't find a solid answer anywhere just people thinking that's what it is, please help before i make this trade i wanna know
