I got a 98 WS6 (6 speed)

Its got 110,xxx miles

Modifications Now
ls6 Intake
Hooker Longtube Headers
Texas Speed Y-Pipe (Always open with cutout)

4:10 gears



If you guys were in my shoes what would you do with the car as in getting more hp out of the car?

I thought about nitrous (wet kit)
But when u start thinking about fuel pump and all the olds and ends it tends too add up with the cost of the total package. Will it stay together on 100 shot

The other idea was a cam with all the supporting mods. But my draw back on that idea was that I seen a lot of lifter failures if you go with to big of a cam. (Must be a 98 thing I'm guessing)

Or just buy a short block ls1 and do a budget build cam and supporting mods with 243 heads and intake.

The car just is here to have fun with a take to the track every now and then

With everything remaining in stock form the car runs 12.82 at 109 with a 1.8 60' on 275/40/17 nitto 555rs

With all that being said would like to get 120 mph in the 1/4

Well it just depends on the budget, but nitrous will be the cheapest and fastest option out of bunch you listed

Not at all, there are no '98-specific lifter issues. The only concern in this regard would be rod bolt durability if you go with a cam that requires you to spin well beyond the factory rev limiter. You can still do a cam (or heads/cam) on the stock bolts, I just wouldn't recommend shifting above 6500ish.

Either way, you won't hit 120mph with the current setup plus only a cam. You would need more power modifications in addition, or some serious weight reduction.

Like posted it all depends on your budget, Your options are FI(nos,blower,turbo),heads/cam setup, or more cubes(stroker motor)...

It's not a hp mod but I'd start with the rear especially being a 6 speed. No sense in breaking the 10 bolt everything you race it. After 3 times I finally got a 9". But to answer the original question I'd vote cam just for the fact of the power always being there. Also sounds alot better. Then spray it

Yeah i thought i have heard about lifter failure. But yes i always hear about rod bolts being a issue. Would the stock pump withstand 100 shot (WET KIT)


Or is the dry kit the better way to go and change injectors

as long as your motor is tight a 100 shot will be fine. as far as wet or dry i dont know but it should get you 120ish traps.

Need to make up your mind lol.. Told ya we can do a simple setup with your nitrous kit and you'd be fine

Unfortunately there is nothing budget once you start building a motor from scratch. A 100 shot is relatively mild, but a better fuel pump is cheap insurance and not much more of an expense as compared against a complete motor build. Also, if you do a search, there is the "trap door" method of installing a new fuel pump that eliminates dropping the whole fuel tank.

yeah ill prob just buy the standalone from nitrous outlet seems like itll just be easier at the end

I would put a clutch in the car because it will need it if you're not already upgraded.

From there I would go cam for sure. Power is ALWAYS there and it just sounds sexy...Filling up bottles all the time gets old AND expensive...Ask me how I know

You DO NOT need fuel upgrades for a 100 shot...Go with a wet kit if you decide to go this route. In order to do it right and be safe you're going to spend close to $1,000 and then add on a tune price tag if you want to play it real safe.

Get the cam and don't look back

Adding only a cam to what the OP already has won't get him anywhere near his goal. He would need heads as well, or as stated above some massive weight reduction.

I've seen cam only cars trap close to 120 in the 1/4.

Most full weight f-body LS1'S (including rims) around here trap 114-116 on average. I'm sure a few have hit 120 in full street trim with perfect track conditions, but I've never personally seen it

z28_YOU_HO

iTrader: (7)

Agreed. Just saying. It CAN be done, especially if he can drive it with that gear.

RPM WS6

iTrader: (3)

I have never seen a cam only, full weight 4th gen trap 120mph with only headers + exhaust, LS6 intake and 4.10s in addition. No reason to get a person's hopes up based on some isolated example with unknown details. Perhaps the cars you've seen had additional bolt-ons and/or weight reduction.

In general, the setup above won't come close to 120. As mentioned above by HCI2000SS, 114-116 would be a more realistic estimate.
