I am currently building a d16z6 so far i got pulleys cam gear throttle body header and intake. I am going to daily drive this car, is there anything i should watch out for with this mods? also the motor has 130k on it should i replace anything while its out? I heard that belts snap with new pulleys is that true?

 

definitely put a new water pump, tbelt, dizzy cap, plugs, and all that....make sure you do it before you get it in the car

 

While the motor is out of the car, you should replace parts that are hard to get to when the motor is in the car. Some parts to consider : timing belt, water pump, thermostat, clutch, and PCV. I'm not too sure about belts snapping from the pulleys, but I'm not a firm believer in those things anyway.

 

i would do a bottom end rebuild like new gaskets water pump oil pump ..me and my friend "SOHC beast" did that in a matter of hours and it was probably the best investment he made good luck man ~~
