i have a 93 2.3 with an 88 turbo coupe turbo set up. I used my original motor and stock wiring harness ( i know that the motor will blow up if i but to much boost to it). i am wondering what i need to get or do to retard the timing. Should i get a MSD boost retard system or should i get an adjustible cam gear. i will be getting a hotter cam for the car. I have the stock spark plugs in, should i go get some lower temp ones? I am running 5 lbs of boost and there is alittle bit of pingin not much but im sure if i get the timing set up it will be alittle quicker.
