give us your planned budget so we can give you a better suggestion on the mods. I would suggest start with these and see how you like it.
cone filter of your choice.
turbo back exhaust.
3-port
fuel pump
good tune --> before doing this make sure to have a new set of spark plugs to avoid down time with the tuning.

For less than 2k this will give you an extra 80whp appx.

 

Andrewwxaragoza, I am only looking to make a decent gain to about 350 or maybe 400. The list you have given is already on my to order list. I might be looking to add a few more things if needed. Thanks for the info.

 

What type of fuel will you be running

 

gasoline premium

 

400 hp isn't the easiest thing to hit on pump gas and the stock turbo..should be able to hit around 350 with some of the previous mentioned mods

 

I am well aware of it. Thanks.
