I am sure this has been asked before but what kind of bolt ons will work on my 91 and witch ones are not worth it I might get into the motor but do not want to spent a bunch of money on a L98 just stuff i could do while i am in there any ways
thanx noel

how much do you want to spend? how fast do you want to go? what kind of power do you want to make (either low-end torque, or high end HP). the biggest mistake you can make is to throw parts at an engine with no goal. Figure out what you want, then go from there. it is much easier and cheaper in the end.
was just wanting to get a little more out of it not no 400 hp just like 30-50 more closer to a LT1 plain on doing the KN & exhaust dont know if i want to do cam want to keep the drivablity good like a stock vette dont even know if I can change the cam with the electronics i have

There is a ton of stuff you can do to your car. I would start with exhaust, and maybe a free flowing air filter set up. If you do a search, I know I have talked about it many times. This will not only provide you with the info from this thread, but info people forget.
The exhaust mods, which include headers and a free flow exhaust will be the most bang for the buck. You should check out Mad Mic's profile for his car domain site. He has a good layout.

The headers should be okay. You can buy them with or without the EGR hardware. Also you can buy a system that has the bung for the Oxygen sensor built into it, so basically it will be fine.
hey thanx a lot that was a great site very helpful thats just what I needed a point in the rite direction now if i can find out whats going on with this 91 exhaust??
I think you get more bang for the buck with a mild cam than you do with headers... If you are looking for more high revving HP, you gotta do something about the intake and head flow. They are the weak link of the L98 by far (exhaust is a close 2nd IMO, but necessary if you do the intake side) If you want to keep the low end torque, headers may not be the best to go anyway.
What I was trying to get you to figure out is if you want the seat of the pants feel (low end torque, stop light to stop light type car) or if you want more HP to really get it to run fast in the distance (think 1/4 mile or more, and top end speed). They are different kinds of speed, and there is a different approach to getting there, especially on a budget.
Headers are going to be a lot cheaper of a mod to do then to put a new cam in, and if you do cam, you might as well do heads and an intake as well, do you really want to spend all that money?? My car has three cats, I am not sure about his 91, but I am sure it is the same. The exhaust is to restrictive, if you want to make serious power down the road you are going to have to do headers anyway, you might as well do them now.
First time I've heard that a mild cam provides greater results than headers on early C4's. (IMO unless you do the work yourself, a mild cam isn't close to a good "bang for the buck" item.)
Besides, a cam isn't exactly a "bolt on"
But if your into the motor anyway slap a cam in there. Decide what you want out of your car and go for it. But regardless of what you decide, headers will be on the list so it's safe to do them first
Agreed, that is why I didnt mod the heck out of my motor when I had it out. I simply did not know how to do the work myself, the labor is crazy expensive, and the price for the parts is not exactly cheap.
neol i got a 91 also
i will suggest the best way to start off is
1 get a goot cat back exahust (borla says mine is worth 13 hp lol might be)
2 get rid of the frisbee (free) (they say its worth freeing up 10 hp)
3 do a tb by pass (only a few $$ mod) (they say its worth 8 hp)
4 do the kn filter and the open air eliment
5 look about getting a chip or timeing advance (ask mad mic)
6 afpr
7 under drive pullys
8 if ur car is an auto might try a shift kit
that where i beleive u should start off
but first off all do a complete tune up
thanx for the replys guys am not new to doing motors and agree with both of you there is a lot of ways to build a motor up like you have to match parts up thats way i have been asking a bunch of dump qs i have not build a chevy up for more then oh sh t 30 years also my first vette
when i got done with my 5.0 last year i thought i had put the right mild cam in but am having idle problems not real bad but more then i wanted SO i dont want the same then with my new toy and who better to ask but you guys mainly want just better performance all the way around with out spending 5k like on stang if i do cam it will only be mild not going to do new heads just rebuild,exhaust,intake but need to find out about electronics with mods
thanx noel
frisbie is the big disk that is siting on the water pump (not the pully) you cant miss it it weighs about 10lbs
the tb is throtle body by pass
look up tb bypass on yahoo or an other search engine its about $5 to $10 mod
the bbk 52mm tb is costly and i dont think it will add enought ($$ can be spent in better places) if i am wrong some one correct me or if some one knows better please give us ur input
but i think if u do the k&n and open lid and a cat back system u will get more hp then with a bbk tb
a larger throttle body (52mm, 58mm) is a waste of money on a stock L98 unless you make the openings in the plenum larger. It's like putting a 10 foot door in front of a 5 foot hole in the wall.

Noel. No one minds folks asking questions, and we're happy to help, but why not spend a little time reading recent posts. Only need to go to the top of the second page to find this
