Or not even better, but more aftermarket.

What I'm talking about is my Trans Am is a 93 and it's really weird, different rear end (series 2 carrier), need 1993 specific headers, can't powertune. Is like the 98 LS1 like this or anything? I've been looking at this Camaro

I just wanna know if like the aftermarket for the LS1 is all the same for 98-02, headers, manifolds etc.

Thanks,

98-00 ls1's had a slightly differant cam than 01-02, however, the 01-02 had the ls6 intake. some of the ls1's still used a 2 series carrier for 2.73's. thats no big deal since they make direct replacments instead of switching carriers. also since 01-02's used ls6 intake, they didnt have the egr hook-up.

 

Aftermarket parts availability is pretty equal for '98-'02 LS1's. However, there are a few things that can make the '01-'02 f-bodies a little more responsive like the LS6 intake, 28lb injectors, better clutch for M6's, etc. There's a couple threads (if you search) about all the differences...

 

This is why you see up to a 20 hp difference when you install a ls6 manifold on a 98-00 car. 2000+ models also had better exhaust manifolds than 98/99. My 98 manifolds are baicly logs, so i swiched to a set of ported 2001 manifolds for the sleeper appeal

 

Yeah, this has been debated over and over again, the simplest answer is this: Buy the one that you get the best deal on. There is nothing that is different enough to cause a problem. The main deciding factors should be the color you want, options installed, and how hard it has been driven.

 

Actually the 97-98 LS1 blocks are different. Thers a oil plug on the back of these blocks that directs oil flow upward and it has known to push out under high pressure . You lose oil pressure and soon afterward, ka-blooey. Time for a new motor. You have the cam difference, but not worth noting. 98 had bigger injectors, if you modify heavily enuff, your gonna need something bigger anyway. Then the intake and egr thing noted earlier. And the PCM is completely different in the 98 fbod. Personally, stay away from the 98, go with 99 up years.


Note: Pace Setter+LS1 = Crap
Little known fact, Hooker is made by the same company that makes Flowtech (Holley), "They're the same sh*t, the same sh*t" and alot cheaper. I learned about this from the Chief Operating Officer at MTI, so I'd say my source is reliable.

Does everyone agree with the above? Sounds like the bottom line on this debate as I have seen/heard this throughout my time here.

 

I've never heard this b4, about the oil plug???
Where is teke184 when you need him????

 

Just emissions stuff

 

2001+ have better heads, 28# injectors, and the LS6 intake manifold.

The 98 blocks and some early 99's did not have the "windows" between the main webs in the bottom end which allows for internal pressures to equalize which reduced blow-by and oil leaks, the 98's have perimiter bolt heads and they are the only year to have a "working " temp guage and the gas tanks are 1 or 2 gallons smaller than the rest of the years.As far as the pacesetters being crap... this could not be further from truth, maybe the older ones were not the best but the ones you can buy from any of the supporting venders right now are of very good quallity and the ease of installation is top notch!

 

OK so they go in easy, but what good is that is they make no gain?

 

SAYS WHO? I not sure where you are getting your information from but that is simply a load of BS! The pacesetters are made from hooker's design so if what your saying about pacesetters is true, then it must surely apply to Hookers and flowtechs right? NOT! Ask anyone on this board who has the pacesetters if they did not gain any HP and see what they tell you, oh let ME be the first, BIG DIFFERENCE from stock manifolds.

 

Hmm...on '02 manifolds and straight pipe, I trapped 106.7mph to 107.0mph. Then, I added a stall/gears and Pacesetters. Typically, you lose mph with the stall. My next trip to the track and I trapped 109mph. So, you can't possibly tell me the headers don't help when I gained 2mph on top of the stall install.

 

Are you kidding? Pleae tell me your joking.
