Ok, so long story short I got a 00' EM1 from a complete moron that replaced the B16a2 in the car with a b18b. I belive it is a OBD2 from the valve cover and going off what the seller said. Problem is he left the factory B16 ECU in the car so over 4k RPM it bogs and runs like shit, so I have been keeping low and slow for the time being. I picked up a p75 local from a guy but 1 of th plugs doesnt match up at all. 2 of them are perfect but 1 os slightly too long for the ECU. If anyone has any help on this it would be great. Dont know if I need to go cut a plug from a wrecked Integra and rewire mine or what. Thanks in advance guys!
