OK.. So I know that this isn't the right section and probably not even the right forum for this. This is also a very noob question, but I can't seem to find a strait answer anywhere including all of the cressida forums. I recently bought a 87 cressida with a 5mge-t engine in it... the guy said that it was recently "rebuilt"... after going to look at it i found that the car was burning oil very badly but the guy said that the ct26 on it was in need of a rebuild... so as gullible as i am i went ahead and bought the car... after about ten min of driving i quickly noticed that the car was already running down a cylinder... it had already oil fouled the no. 3 spark plug... i decided to do a compression test and it reviled a very lazy no. 6 and shot no. 3 (like 50 p.s.i.).... this brings me to my noob question... i have a 7mge out of my 87 now 1j supra.. i don't have a wiring harness due to having to spider it into the 1j harness for the swap... so is there any way that my 7m will work with the 5m electronics? I have herd of guys running 1js on 7mgte electronics but i was wondering if 5mge to 7mge would work also... and to those veterans of this forum I'm sure this noob thread is gona piss you off and I apologize but I'm in need of help.
