Ok, I've been thinking about replacing my stock injectors with a comlete performance injector body with nozzles, or just buying performance nozzles and keeping my stock bodies. Right now just thinking about 100hp injectors or nozzles. What is the "best" way to go. The cost between the two is what makes me think the whole injector body is the best way to go becase it costs nearly 3 times as just nozzles, which makes me think its a far safer and a better way to make power. Is there a difference in power between whole injectors vs just nozzles? Will the stock bodies hold up with just performance nozzles on (i.e. not crack)? I luckily just had all 6 injectors replaced under warranty, whew!, but now want to take preventative measures on my own. Also are the f1 flux brand injectors, or just nozzles? Any input would be appreciated. Thanks
