hey i have a ss/sc and my girlfriend is looking at getting a ls auto tom and wants to supe it up what are the options that i have... i know there is exhaust intake and no2 but how can i tune it ? also can i run larger injectors ? just trying to get an idea of what i have to work with... i dont want to boost it

 

Larger injectors are useless on an NA vehicle. Stock is more the adequate when looking to fuel the vehicle.

Tuning will have to be done through Trifecta.

 

Other than full bolt-ons, you're looking at nitrous or boost for "suping it up". N/A builds are not cheap to do, and definitely not as cost-effective (although the few built 2.2's i've seen/heard are ******* awesome).

 

Sounds like you might want to start with the basics like intake exhaust, intake and exhaust manifolds, and a downpipe. Perhaps a trifecta tune. That should be a good start.

 

I would read the stickies (thread up at the top of each 2.2L L61 Performance Tech page) for ideas and start searching for the types of experiences different people have had with various set-ups.

Depending on your mod level you may eventually need bigger injectors but AFAIK out of the box and with some boltons thats not needed.
