Im looking for a good write up to replace the stock secondarys. Ive searched but couldnt find anything, Im sure its out there, just must have missed it.

 

Look in the FSM for the procedure. If you'd told us what kind of RX-7 you have I would've given you a page number. Putting "Chevy Blazer" in you profile isn't very helpful...

 

yeah what year car and is it n/a or tII? what injector size? are they low or high impedance?

 

1989 TII, they are greddy 720cc, low impedence

 

Also I know about adding the resistors and whatnot, I just got the car and need to replace one of the injectors, so I need something detailed enough to walk me through what I need to remove to get to the fuel rail. Thanks for the help guys.

 

do you have full emissions? I have none so its just a matter of taking off the intercooler piping (for you since it's probably stock you will need to take off the intercooler and piping). Once you've taken that off you will take off the throttle body and then the upper intake manifold. Once you have removed them then you will have full access to the fuel rails. There are going to be quite a few vac hoses etc if you have emmissions so just make sure and remember witch ones you take off and where they go. Use some masking tape and a permanent pen if you want to lable them. GOod luck.

 

Yea I have the whole set of block-off plates waiting to go in also. So all those vac lines will be gone.

 

cool, right now would be a good time to do that along with changing your injectors.

 

I figured so, I just havent done muc work on the engine so I dont know how everything comes off and what not.

 

Well I would search for each inparticular part you want to block off (ex. acv block off) Really I wouldn't know jack **** if it woren't for this forum. As long as you search your *** off and post when you need to you will turn into a pretty damn good rotary mechanic

 

i don't mean to hijack the thread but i was wondering how do u check the iimpedence on the injectors? i did a search and looked at the FAQ's and all i got was the size. i want to put bigger injectors but i dont wanna screw up the system.

 

you wanna know if the injectors are high or low or the car is high or low? If you have an 86-87.5 then it is low and if you have 88-91 it is going to be high.
