HI Guys, just wondering if anyone could help me. I just did a engine swap on my friend's EK4 (ek 97 vti-r with B16A engine) australian version with 98 JDM Type R B18C. I swapped the looms from the B16 to B18 and everything pretty much plug and play. the car starts but i have an issue with engine cut at around 2000rpm. when i tried to rev it, it cuts and car stalls. I checked the fuel line and everything seems to be working just fine. I tried both B16 ecu and B18 ECU and it doesnt make any difference. I also noticed the the tip of the sparkplugs goes really black.. Im stuck and dont know what to do now. can anyone please help me? Thanking you in advance.
