haha good laugh for the day hehe
actually i heard of a guy who did a 150shot and the motor made it 2 runs till he caught fire after it exploded but 75 shot max with retarding timing
but no more than a 50 shot if u got over 100k and no nos if the motor isnt in excelant condition
u know what i hate about zex its kinda like women, if its to easy, theres something wrong with it
but yea 500 for nos or 1200 for motor? id go with the b16a1 and build from there not much of a gain for baseline but can be a mean lil bitch after built
but since u know nothin about nos id say get the motor cuz ull be buying one soon anyways
