OK I know im going to get a lot of **** out of this stuff but here it goes.

I am purchasing an injen CIA, ZZP header DP no cat, and a 3 inch cat back system, dont know what cat back yet.

SO I got a delema here, should I go with a 2.7 pulley and 42# injectors or 2.6 pulley with 60# injectors.

Please keep in mind that this will be a daily driver. So I need it to be not so radical. But still kill the mustangs.

Oh yeah, is that the right match for the injectors and pulleys?

This all will be tuned afterwards.

Please help.

 

well if you go with a 2.7 get 60lbers as well...

 

dont waste your time w/ the 42's, go w/ the 60's and 2.6 and you should be ok for a while but you should look into cooling mods also

 

So are the 42# injectors not enough?

True but I have not found any cooling mods anywhere. I cant even find a colder thermostat

 

true you need 60's witha 2.7.

you need to look into a dual pass H/E plate or a cobra heat exchanger with a 2.6 and 2.5

 

I wont need a new adjustable tensioner pulley with the 2.7 pulley will I or can i get away with a smaller belt

 

not positive on that,you should be able to though... im running a 2.7 with a oversized tensioner pulley with no issues
