720cc injecter question
 

So my girl is going to get me some injecters and a ECU for my bday. was told a Rtek7 and 720ccs where the way to go so i need to find out what kind of 720cc i should get. i have the stock s4 2nds on my motor now.

any one?

Check the FAQ it is all listed there.
I am in the midsts of fitting my 720's and plugging in the Rtek...hoping all works out.
Make sure you pay attention to Low Impedance or High Impedance Injectors. Some systems will require a resistor to be added.

ya i also have to find out if i need high ot lows but i'm hoping to make my friend do it =P

and i don't know the year on my motor, only know it is a s4

you can match the part number on your secondary injectors and match it up to the rotory resurection chart and it will tell you wich you have Low or High. Thats what i did.

go to tech
and then injector information
this will let you know if you have high or low imp.


*edit* to slow!!! LMAO

is there a way to tell with out taking off the top intake thing

From what ive read on here its something like if the car is an 87 1/2 and up the injectors are high imp and if its 87 and below its low imp.

its 88...:D

cant you reach the secondaries without ripping IC off???

i dont have a turboII...lol

i thought the 2nd where under ic on a 13bt and the body is 88 but the motor is unknow, mostly s4 with a few s5 parts

whats the number on the top of the ECU

All the injectors are under the Intercooler and Throttle body for the S4 turbo.

dude.... go with microtech... ive heard nothing but good things, and ive had no problems in the least... if shes gunna buy u a n ew ECU go hard or go home.. lol

sick ass site thanks

pfff not paying $1000+ for a ecu when i can get a nice one for $125
