ok guys picked up a 1998 gtp today black 4 door has a 3.4" pulley ported blower cold air intake 3" catless downpipe what is my next option i want the best horsepower i can get out of it and the best bang for the buck let me know my options???
 


you need need need a PLOG or headers and a scan gauge for it. Read the Safely Modding Your 3800 thread in the general tech section.
 
what would you recommend a plog or headers or both? give me a heads up i skimmed over the basics of the safely modify and said stay away from zzp computers whats a good option prolly gonna port my throttle body best scan tool i know ALOT about gm products and cars in general just traded my 01 a4 v6 that needed a head gasket for it so i got a good deal
 
LOL at stay away from ZZP computers. I put down 271hp/325tq with one of those when I was supercharged and a 3.4 pulley setup. I'm currently running one with my turbo setup(installed this week) and no issues.

If staying supercharged then go with headers.
 
ok cool idk just when i skimmed the safely mod said that... i really have never delt with superchargers i have a built 98 neon turboed running megasquirt first gtp first supercharger first family car :)
 


no, don't buy the pace****ters. they are guaranteed to leak without modification. a PLOG is just an aftermarket front exhaust manifold, headers are the front and rear as well as a downpipe. There is also a sticky thread on here called the Header thread that breaks down all of the options. The Speed Daddy headers from ebay are a popular choice because of their price but go read that thread before you make a decision.
 
looked all over ebay can not find the speed daddys i am not spending more than 500 on headers i know there is plenty of options will check the thread out

thank you very much i have seen alot of people using the speed daddys with no problems at all i think i may order them tomorrow along with the aeroforce gotta memeber people its a family car too haha just a little fun to play with... should i go any smaller pulley bigger engine pulley? cams springs retainers? wanna hit 13.9
 
theres only one cam, and you dont have the supporting mods to run the pulley you have now, smaller pulley=boom boom. dont skim that thread, read it and learn.
