ive more than doubled my power so far from stock, and i daily drive it, but just because youre making the power doesnt mean you have to gun it everywhere. my car sees maybe 5psi on a daily basis...MAYBE if its lucky. so the key is, drive normally, dont gun it everywhere, if you want to rag on somethin or gun it everywhere, go buy a stock toyota econobox. now if you daily drive it and take care of it, youll get alot of enjoyment out of it at the right times. im not here to tell you how to drive your car, but i am just giving advice on how to keep it running. part of the reason i havent had anything breaking on me, is whenever the car is in my garage, i have the hood up and am always checking over things, now with something stock, you wont really have to do that.
