Thread: Need Help Upgrading '04 Grand Prix GTP

Ok guys I just bought my 2004 Grand Prix GTP Comp G and really want to upgrade the engine and allow it to hang with my buddies stock 1998 z28, which is putting out around 350hp maybe. Anyone have any ideas about what i should put into it. Looking to spend a max of $2,000 possiblly and dont want to get into rebuilding parts.

Wanted to put in cool air intake, 3.4 pully, PRJ Performance Ignition Wires, Dual QTP Electric Exhaust Cutouts, and I dont know if it will add anything but the Inferno hood from PFCY.

Any ideas would be apreciated.

Since you mentioned a majority of the parts that I sell i'll go ahead and step in.


I have the plug wires and the cold air intake. All at prices that are much less than anywhere else.

If you have any questions be sure to let us know. Do you have a goal for the car?



Welcome to the community.

I want it to be in the low 13's or mid 13's. Was thinking about a 3800 performance staging kit but seeing as everyone is against them not sure anymore. Also might be buying those plugs in the near future. Not sure about your intake because it says 97-03 not '04.

want the cutouts bc i like the noise but i dont know if i want to hear an exhaust in the the morning when driving to work.

Cool. We offer intakes for the 04+ It's just got a section cut out to allow the MAF to go inbetween.

buy an intercooler ^ he sells them!! best mod for the money then you will be keepin up for sure.

thanks for all the info guys, i think im going to look into a intercooler, pulley and a intake.

DONT BUY A CUTOUT on these cars ive tried GARBAGE unless turbo'd (i miss mine)

but def do a full IC, rockers, maf, intake, headers, you'll need fuel rails (prj ftw), umm throttle body turn down, wideband, 3.0 or 2.8 pulley
i used to have the same setup and could have done the 2.8 with no problem (but i also added a nice little cheater ice box in the truck!
i have a 04 gtp as well!
ill be doing the same setup again

and we have the gen5 phenolic intercooler for you too.
