Should I add bigger injectors?

Also I am thinking along the avenue of a bigger throttle body and manifold soon enough. Is it a big job to replace these? What size?

Suggestions be great - I wanna keep it N/A(no turbo, NOS, or FI) .

It's my DAILY DRIVER too btw..

 

there is no need for injectors, and a bigger TB will not yield good gains for the cost with your mods right now. I would look into a set of heads, with a good set of heads you can pick up mpg and obviously power at the same time.

Suspension is always a good thing to get her to hook and look good.

 

New gears? Then tune

 

ASP underdrive pulley

 

I'm worried new gears will **** my shitty old stock rear end. any predicitons on that.

also, what beneifts can be seen from the underdrive pulley

 

bump!!

 

Suspension and free mods FTW

 

If your running a bone stock throttle body, I think that would for sure be a worthwhile upgrade. At least a really good port job on it.

 

it's already ported and polished, forgot to mention that sorry.
