ok well i was wondering as far injectors go....i want 42lb injectors...but which harness do i need?...i was looking at this sight an this is what they are selling...would it work with my car?...http://www.lightningforceperformance...kit-p-520.html......what harness do i need?

and also what spark plugs should i look at?...or are the standard plugs sufficient to handle boost?

 

There seems to be a discussion on injectors here:

You will be alright with just stage 2 and 42's. You can use NGK Spark Plugs (BKR7e). It's recommended to use 1 step colder but not necessary. CA has them. Those LFP look ok to use. If you are going to spend on 42's, I suggest you spend a little bit more to get some 60's. Just my thought.

I went with stage 2 42's. To use any injectors made for the ss/sc you need the injector harness from an 03-05 cavi or sunfire.

for plugs: i haven't got the s/c in yet, but i have a set of NGK copper plugs meant for the turbo 2.4 solstice guys. I'll get you a part number when I get put them in tomorrow.

 

are u a 2.4...if ur not going s/c or really t/c u wont need 42's...32's will do the job..the 32's are the stock ss/sc injectors

 

2.4 s/c, and I'm using 42's as an extra cushion when I upgrade.

 

same for me...i havent started with the build yet...but i want to be in safe range with tthe injectors rather than close to over doing it....

 

You need the 2.2L Cavi Harness

GM Part #15411879

$74.80 total from GM Parts Direct

http://www.gmpartsdirect.com/

 

and that works with the ss/sc injectors or any injector for that matter?

 

any injector made for the ss/sc...

so it will work with the stock 32's the stage 2 42's or the 60's (are there 60's from gm?)

 

hey pjk hit up your build thread i have some questions for you....as for the harness...thats a good thing ill save some money then

 

can i pick up a new set of 42's for a low price or do i have to buy them used...anybody know?

 

I'm not sure how much they go for new, but USED I paid $90 shipped.

 

I acually am probally making this my first mod/ with a nice tune

 

Shouldn't need 42's or 34's for that matter if you aren't boosting. A tune would help though.

 

yeh man I ment the stock ss/sc headers not the 42s and from what I here Putting them on with the 04cavi wireing harness and tune is only tune worth getting so far
