I'd imagine maybe 15-25 hp. You'll need a tune to make good use of those parts. The light weight crank pulley isn't a good idea.

First off - Is that with cat or without cat?

Secondly - get a flash. You will not notice much without that.

I would also go with the Walbro 255 fp.

See my sig. I have a similar setup minus the header, ported turbo, and pully. I made 320 whp and 305 wtq on a dynojet at about 68 degrees.

^^ Agreed the pully isnt on my list. Watch out with the header also, those can cook many parts near them, and they can adversely affect power. The stock manifold is actually decent.

Right now it has the cat on it..but soon to be replaced with a Downpipe....I Read the crank pully is ok due to the balance shafts on the vehicle....What is a walbro 255?...Sorry not familar with some of there mods...I will do a search... Plus will i get a check eng lamp when i replace my downpipe?..Thanks again

P.S putting the header on made a huge difference on the but dyno..I mean like Night and day.

A Walbro 255 is a fuel pump. Flows better than stock for when you need the gas. When you change to a high flow cat or without a cat - yes you will get the CEL light, but there are 2 fixes for that - mechnical in the how-to section and the chip verison that you have to wire in.

But again, a flash is what will bring the car to life.
