so would these be the right mods?

this is my plan for my car 1999 gst spyder 5 speed. just tell me whatcha think and what you think ill be sitting at the wheels...

3" whole exhaust (downpipe, o2, hollow cat, cat back)
intake
front mount intercooler (medium sized)
BOV (i know no horsepower gain here)
255 fuel pump
550cc injectors
big 16G
plugs and wires

you are almost positively going to need a Safc/logger solution or a DSMlink also..

Looks good otherwise. Maybe 300ish... But built it and then dyno. Then you would get a much more accurate number

You know you need a fuel tuning device right?

It depends on the boost, gas, tune, and many other things on the car, but I would expect mid-high 200's.

Also you NEED to start using the subforums. A mod should not have to clean up your threads all the time.

Looks like a pretty good list but you forgot a Fuel pressure regulator and of course some type of tuning device as they said.

once again thanks guys and gals. sorry if it seems like a got a lot of questions i used to be a 3rd gen guy. so what else would you recomend to add to my list to be at about 400 to the wheels. oh yeah and i will add fuel pressure reg and 17 psi.

Noooo, we like questions so let them flow (seriously). You will not be able to squeeze 400 hp out of that turbo. IIRC, they will only flow enough for 375-380. For 400 hp, I would get a 50 trim instead a 16g, get DSMlink for a logging/tuning device, and get some bigger injectiors. DSMlink will work with any size, 650's should probably be ok. If I am working this formula right, the 650's should be able to support 450 safely. Nitrous may be of interest to you as well, but you have to have your shit worked out before you start sprayin.
