Hi, i have a 1990 celica all trac and i found a jdm 1993 RS/CS celica front clip... i was wondering if i used the jdm ecu will my speedometer read correctly? like it wouldnt be read wrong being my celica from Canada and the front clip from Japan... and whats the speed cap in Japan? will i need to get a speed limit defencer? is there anything else i will need for it to run correctly? is there any other info i should know about while doing this swap? sorry if my questions are confusing...
