hey rx7 club just have a few question about injectors. (noob to rotary)

i pulled the intake manifold off today and got the injectors out. they are reading 14ohms. i kno thats in spec, but im not sure of the spray pattern. the kid i baught the car from said it needed one and all of them seem to ok as far as the resistance check goes. im ordering some tonight anyway cuz the insulators are cracked and breaking and they are really rusty.. the gastket on the manifold seems to be in perfect condition, doesnt look like the car was eve run since its been on... i baught it hoping for a daily but its turning into a project... ANY ADVICE? id love some! when i get the injectors im putting them on and draining the gas tank and putting fresh gas in and im also doing a coolant flush... and im going to HOPE it runs fine after all that.. also i was reading that the injectors have to be angled a special way?? any advice in doing that as well?

Thanks again for looking all!!! much appreciated.

 

oh by the way its a 91 turbo 2

 

resistance means nothing as to whether the injectors are good or bad, for example i just sent a box of 12 injectors to the shop to be tested and 10 out of the 12 either did not work(most were inoperative actually) at all or had low flow. they had been sitting for a while but i tested the resistance on all of them and they all were within spec before i dropped them off.

 

oh lol, well ok then... well since the kid i baught the car from never specified which injector was bad i suppose it would be best just to replace them all...he said the last time he drove it it ran...just a little funky and said that the spark plug closest to the front of the car on the bottom was always dry and assumed that, that was the one thats bad... if it still runs funny after i replace them what else could cause the rough idle and driving condition. also how do i angle these injectors correctly? helpfull hints or tips? maybe a picture?

 

The injectors don't get angled. As far as the rough running condition use the search function.

 

hmm, i read a few things saying that they had to be angled a specific way including ALLDATA. but ill take your word for it, you guys seem to have the best knowledge about these cars

Thanks.

 

The injectors only install in one way. There isn't any way to change the angle.
