I have a 04 ec 5.3. I am considering the sts kit. What other parts are REALLY needed to comlete the install to have a dependable upgrade. i.e. injectors intercooler, or programming?Thanks, Rodney "slowec"

 

You already mentioned them.

Injectors, fuel pump, intercooler OR meth, and a custom tune. A good boost controller can make life easy too.

I started with just meth and it works great but ended up getting the IC. I kinda needed it once power levels rose.

I would also set a goal for the truck and choose the turbo accordingly. Why waste another $700+ to upgrade the turbo later. Just get the GT67 now and deal with a lil lag till you get everything finished.

 

F8L beat me to it, but I would have to reccommend doing the setup I just did.

Go for the bast kit. The Base turbo will be a decent choice, or you can spend the extra $$$ and upgrade to a bigger one. The bigger the turbo, the more high end pulling power there is, but on the other hand, it will lag more. I went with the gt-67 since my future motor mods will mate better with it.

Talk to Rick@Synergy... he now makes the FMIC kits for the STS... It comes with all the neccesary piping, clamps, fittings, and intercooler.


You'd need to get new injectors, a bigger fuel pump(I went w/ and in-line walbro 255), colder spark plugs, and a boost controller. A boost gauge and fule pressusre gauge are also good to have.

then get a custom tune. On the spot dyno tunes are the only way to go if you are doing a bigger power adder like this one.

 

Amen. If you're going crazy, get the meth and the FMIC and then run 20psi

 

Hey Erik. What injectors are you doing? I need to get something at least 60lb and I was pretty sure they would end up being F-bod style so the harness will have to be modified. Just wantd to make sure before I give Rick the goahead to order some.

You'll like my new setup. Not as cool as yours but for a budget I am hoping for low 11s.

 

If you had sufficient injectors and fuel pump, what psi is the GT 67 good to on a 4.8 or has this frontier been tested yet with the sts?

 

Damn you guys, I step away from my computer for 5 minutes and you got all the answers. And they got them all right. Yea, what they all said.

 

You don't NEED any of those if you are going to leave it at 5 psi, although they would all be good. Of course, who is going to leave it at 5 psi???

Boost controller on it's way as we speak.

 

Tsk tsk tsk...... Jerry, what are you dooooooiiiiing?????
