Anybody have any thoughts on this. I have an 81 turbo and have replaced three injectors with rebulit ones for $30 each. The car seems not to have enough fuel under full boost and the throtle does not seem to "snap" open, but gradually opens up. The car once had a fuel leak at one of the injectors, (since fixed) and it drove exactly the way it does now. I've replaced a few injectors, one rebuilt one was dead on arrival, one only lasted a few months and the other ones performance is suspect. I'm thinking of getting all new nissan injectors, but at a cost of over $100 each, I want to make sure it's necessary.
