[ZR1Vette09]

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.

[r13evenson]

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

[txslow6]

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.

[r13evenson]

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

[r13evenson]

oh and i meant better option plog or headers?

Pacesetter Headers 97-03 Regal GS & Grand Prix GTP 3.8L | eBay
order them now?? fair price i have good luck with pacesetter just had to get them leak tested

[ZR1Vette09]

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.

[r13evenson]

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

[r13evenson]

thats what i picked up today

[ZR1Vette09]

speed daddy's are roughly 230 shipped if i remember right.

[Slick2500]

Speed daddy headers

DNA Motoring = Speed daddy. I think they changed their name.

To scan get this Aeroforce Interceptor Gauge

Or go all out and just get HPtuners

I would not get into boost unless you want this

[rynoman03]

Turbo Kits, Turbo Manifolds, Import Performance Products, SSAutochrome Inc. for Headers

[r13evenson]

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

[boostedcompg]

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.

[NegativeOne13]

Here are SD Headers... a few bucks cheaper than DNA Motoring.
