Choices for 50-100 HP upgrades

[NukedGTS]

I'm sure this has been discussed in previous posts but I tried a search and had no luck. I am interested in adding 50 to 100 HP to my 97 GTS. Existing mods on the car are RT Hi-flos, 3" Corsa catback and a K&N box. Any thoughts?

Headers and a Cam. Kinda the basics

if doing a cam, might as well do heads.

Great topic. For the newbies to these cars like me....Just curious -

What kind of HP are people getting out of the cam and header upgrades?
What are people buying and installing? What are some preferred choices?
What is the price or price range for these upgrades?
Who does good work?
Any reliability issues?
What are people's experience who did this upgrade - was it worth the money?

Prices have likely changed...

Recommendations on the Cam ?

You may want to consider an SCT programmer once your mods are completed. In anticipation, down in the forum section under new items, etc, they are running a group buy for a ROE SCT purchase.

Good luck, jim

Just do stage 3 ported heads, that will get you 60rwhp.

60rwhp is the type of number I'm looking for. A guess on the cost, mat'l and labor, for this type of improvement? Any other add-ons needed?

looking at $4700 for the heads. Im not too sure about the labor. You will also get more power with headers to.

You may want to talk to Greg Good about the work he does on Gen 2 heads. 4700 seems like a lot of coin compaired to his prices..

Headers and 1.7 Rockers would be a good place to start. Reliable and easy to do.

Stop, engage brain..

50hp isnt worth the $$$$
100hp gets you COMMITTED. Going to get committed....get planning!

Save your cash, plan your build, start out properly and you wont be throwing out stuff a year from now.
Wnat to feel an improvement? Well, you can throw out headers...you'll hear it (ugghhh) but you wont see it or feel.

1. You WILL NEED roller rockers, and you will feel them too.
2. You WILL feel heads, but you have bought your ticket on one ride going in one direction. Its a great direction, but is it where you wanted to go?

Are you one of these guys that is going to Supercharge/Turbo your engine down the road? If so, STOP!
and plan it all out with yourself or the guy(s) that are going to do the work.

Very Strongly 2nd that.

Start with the bolt ons, and then make more power.

On bolt ons alone, I make 478rwhp and 510rwtq, and ran 11.50's at 125mph

Headers, High Flow Cats, Cat Back, T&D roller rockers, K&N and Smooth Tubes, mopar PCM, alumn flywheel, 708 cam, and even get/find a set of smaller pulleys (if your going to stay NA).

Also get a B&M Ripper shifter, for quicker and more percise shifts.

Ok, my work here is done.

What he said

There are a few basic mods you can do to get you rolling, not have to redo once you go FI or Heads and have you spinning the dyno at near 450-460 wheel horsepower.

1). B&M, Hurst or SVS Shifter (great upgrade to the stock shifter)
2). Smooth Tubes and K&N Filters
3). 3" Exhaust, Corsa and Random Tech seem to be the two most popular right now
4). 3" High Flow Cats
5). 1.7 Roller Rockers...Harland Sharp seem to be the most cost effective of your selections

At that point you are going to be looking at heads/supercharger/turbo. All with their own benefits and all costing significantly more than typical bolt on power. .

Thanks for all the input. I am pursuing the 1.7 Roller Rockers. Only held off on the headers when putting on the Corsa and RT Hi-flo's because of noise issues. If I hear a Viper this summer with that setup and like it, I will definitely go with the headers as well.
