Mod Question on 98 Fbodies

[Justin93]

Hey Guys Im new hear and Im crossing over from the Offroad jeep world once I get My modified 06 Wrangler sold. Im currently looking a a few Fbodies in my area ranging from 98-02. My question is I have Heard from my buddy that goes to UTI that the 98 model year has some quirks in the computer that doesnt allow it to accept computer mods as easily as the 99-02 models.

I also noticed that on SLP's web site there isn't any Programmers available for a 98. I am wondering because I found a really nice low mileage T/A and The last thing I want is to throw the whole SLP exhaust package and MAS air on it and not be able to tune it out to tie all the mods in correctly.

Thanks for your time. Sorry if I sound like a moron lol Im still new to the LS series motors and seem to be a whole world different form the lt-1s and old school 350s Ive worked on Before!

i sent my computer out to pcm for less and they custom tuned it for the mods i had dont to the car. i think i payed like 300 for the first time then its like 50 for everytime u send it back after that. I would recomend that over a hand held programmer.....imo

I love my 98. With the steel tank, working temp guage and all its wierdness!!!

First of the last breed :) lol

[Mr. Luos]

Never visit SLP's site again.
That would be your best start. :yup:
Do NOT buy any parts from SLP either. No customer service, overpriced, bloated HP claims. Ask most anyone.

Do not go with a computer programmer. You are wasting money. Tune or nothing.

[Justin93]

yea Thanks for your help guys that makes me feel good about going to get this bird. I got talked out of the SLP stuff By my buddy who has a 93 with a rear mount sts turbo. He said the only nice thing they have is there long tube headers and cats.

The dynomax rep was in town traning us on Jeep exhausts on friday and after hearing some sound clips of his personal 98 SS I think that is the way im going to go especially with the discount i get on their stuff!!!

[Kup98ss]

Slp headers suck as well.
The only good thing they make is their new better fitting lid.
I had a 98ss and I loved it. I still miss it.

Tell us about this car you are looking at.

[Mr. Luos]

He said the only nice thing they have is there long tube headers and cats.
SLP has some of the WORST headers on the market.

[02cetransam]

SLP has some of the WORST headers on the market.

agreed!

[Justin93]

Well its a 98 6 speed car with 35k miles and t-tops. The guy only wants 14k and it looks great in the pictures. We shall see in real life this week. Its just a Trans am not a WS6 however it has all the options I wanted short of being a WS6 amd os all stock still. Im Just hoping the jeep is gone within the next week or two so I can go grab that thing!

So what headers do you guys recomend? Id prefer something stainless as I live up north for the time being and wont be taking the TA back to florida for another year untill school is finished.

[JoshieDoom]

Kooks or pacesetters are what most people recommend on here..

why is that?

[fbird777]

why is that?

They sit too low after being installed, some people bottom out in driveways, scrape, etc.

oh that sucks, one of my friends just got them. do they flow crappy?

[Justin93]

Pacesetter? wow usually I equate their stuff to being bottom dollar get what you pay for exhaust. Ill have to check them out.

[Mr. Luos]

oh that sucks, one of my friends just got them. do they flow crappy?
No.
They flow on par with other headers that fit.

[tigersport14]

ah ok thanks.

[Blue_98_ws6]

That's a bit high. It better be in mint condition.

[Speed Psychosis]

98s have better built steering wheel controls that won't break so easily and have better throttle response. :thumbup:

[Mr. Luos]

have better throttle response. :thumbup:
Must be those lower flowing heads. :D :D

[purplebat66]

and better cam

[Mr. Luos]

and better cam
And LS1 intake. :lol:

Honestly...the biggest difference is the heads. Perimeter bolt valvecovers. They don't flow that bad, but are the lowest flowing out of the F-Body LS1 heads.

The cam size is SO minimal, it doesn't make much difference.
199/209 498/497 119.4 for the 98-00 years.
196/209 464/479 115.9 for the 01-02 years.

[Justin93]

Down the road I plan on putting on the LS6 manifold, heads and hot cam it so thats not that much of a worry for me. Any ls1 is better than the whimpy inline 6 thats in my jeep::brick: im thinking of offering the guy $12,000.

[Mr. Luos]

Skip the hotcam.

If you are looking for something smaller...go with a TR224.

1998 F-Body


6. Steering wheel controls were completely different part with indentations on the buttons, and were better built

12. 1998-1999 LS1 cars had a smaller throttle body cam, which caused the throttle to open to WOT (wide open throttle) faster than 2000+ cars


from the sticky itself. i haven't driven another one hard though so i don't know what the response difference is.

[Mr. Luos]

from the sticky itself. i haven't driven another one hard though so i don't know what the response difference is.
I was refering to the actual cam inside the motor...not the TB cam. The TB cam size difference wouldn't be noticeable.

[Justin93]

What do you guys think of these?
