i am going to heavily modify my gt......blown or supercharged, i haven't decided. what lbs. injectors do i need....are they a pretty easy install...easy to get to?

thanks

 

blow or supercharged? aren't they both the same?

i think everyone gets 60lb injectors, i'm probably wrong as i'm not in that stage of development on my car yet.

 

they are a very easy, straightforward install.

the size you get, will be based on the setup
you go with and the rwhp goal you have in
mind at the time

 

If you change the injectors you will have to change your tune at the same time...unless you are getting a tuner with whatever kind of kit you are buying you won't be able to perform this upgrade...I lucked out and found a tuner that would mail me a base tune so that I could drive to their shop and get the final tuning completed...

 

^^^Completely agreed.




On another note:

-39lb injectors pretty much come standard on all FI kits for our cars. They are sufficient until about 500hp range. Assuming you have the proper fuel pump & fuel pressure. Some kits use aftermarket pumps, and some use driver modules(boost-a-pump) to increase fuel pressure under load. Myself, I have both. The injectors are as easy as removing a couple of bolts, disconnecting the fuel line, and then removing the rails. Remember to use a lubricant on the o-rings on the new injectors to keep the from damage when installing. I recommend using a very thin film of axle grease.

 

I went overboard and went with the 60lb injectors and the GT500 pumps and driver module. Little extra insurance for the motor! J

 

I have 39# injectors in mine..

 

I am selling my 39# so that I can get 60# I ran out of injectors on the dyno and the only way to eclipse 500rwhp and rev to 6500rpm is to use those injectors...so saying they are good for about 500rwhp is pretty acurate...
