Hey guys,
I am about to take off a week between jobs next month, and I want to use that week to mod the h*** out of my Grand Prix.
Right now I have a 3" Catless Downpipe, slotted airbox (just to hear that whine), 180 t-stat and a cleaned up throttle body with fresh LIM gaskets.
I have 0 KR, and Im ready to mod the beast.
As the title says, I'm looking to push over 400 horsepower in as affordable a manner as possible.
So far, from my readings, I've determined that I'll need headers, a CAI, Injectors, Sub-3.0 pulley, XP cam, double rollers, Northstar TB, Plugs, and an Overkill tune.
I'm just looking for people's inputs as to what I can do to the car that will get me where I want to go for the least amount of money.
Will my idea of the above setup get me 400hp?
I'm considering the Ebay headers, since they are only about $180 new.
I am also considering buying a slightly knocked up XP cam for $200. The guy selling it says its not much damage and it will not affect performance or life of the engine, its more cosmetic.
I have a 96 deville with a 4.6 Northstar that I will take the TB out of, but I am questioning if that will fit.
for a cold air intake, I plan on running 4" ductwork to the grill, and plugging a filter into the airbox. That will keep it looking stock.
Let me know what you guys think!!!
PS I know people will hate on the ebay headers, but is there actually proof that they suck?
Thanks so much,
Nickolaughagus
