i see a lot of people dogging on the KA..yea historically the SR20 has been favored but lets look at them both as N/A motors.. the KA has more torque doesnt use pushrods making it rev quicker and more reliable at high rpm's and yes they did use KA's in trucks.. why because they have good torque. I have a '94 altima which is KA powered, i am running a set of SR20 underdrive aluminum pulleys, a DNA motoring stainless header, cold air intake, also using a 240sx maf sensor and a set of 10.2mm plug wires from vision works and have an aftermarket chip for my ecu from E-mance and while its no racecar it has hurt more than its share of feelings on the street against many v-8 cars... so as far as it being junk i dont agree, when your ride breaks down call me and ill tow you home with my KA...lmao
