Alrighty guys here is the deal. I have a 2005 GTO auto (LS2 motor) that is my daily driver. I have my goals set at around 410RWHP. Stock with 900 miles on the car I dynoed at 330RWHP.

Anyways right now I have plans to put on Stainless Works long tubes with their high flow cats (the LT's are heat coated as well). Custom 2 1/2" ture duals with a x-pipe, Borla XR-1 mufflers and 4" round polished Borla tips. I'm also doing a K&N cold air intake, B&M tranny cooler and a dyno tune. I'm thinking this should net me around 380RWHP (I hope).

Since I'm getting a dyno tune I've also decided I will go with a cam... which cam is always the question. I've done a lot of searching and I still can't decide which. I'm looking for a mild cam, that wont kill my gas milage. One that will give good power through the power band (1500-6500RPMS or so) and give me a nice power curve. I don't have to worry about a sniff test/emissions. I'm looking to get a solid 30-40RWHP out of the cam.

So at first I was looking at the TR224 Kit (224/224 563/563 114). It also comes with Comp Cams 26918 Valve Springs, Thunder Racing Stock Length Pushrods (7.400) and Titanium Retainers for less than $800 shipped. Though I'm not sure if this will give me a solid 30RWHP... should give a pretty nice power curve though?

Now another cam I was looking is the G2 G2 (224/224 580/580 114). This cam should give me 30-40RWHP with no problems IMO. I could go with the G2 G2 kit but that costs $1200, so I was wonder if these parts would work with it for $1015... Comp Cams 26918, Comp Cams titanium retainers, Comp Cams Chrome Moly pushrods. I'm also wondering if this cam will be really hard on the springs and if I would have to replace them often?

I also thought about getting a custom cam made from Ed at Flowtech Induction, though I don't know how much the kit will cost and it will take too long... I want to get this done by Fri of next week (Dec 9th).

 

For what you want go with the TR kit, there isn't much diff in cams other than lift and you certainly wont get an additional 10 RWHP out of the G2 cam over the TR cam setup and the $ you saved will pay for the tune!!

 

Well the shop that is doing the work on the car said I would need to get a bigger cam to reach my goals. They said the LS2 has a cam pretty much with the same specs as the LS6 cam. So going with the G2 G2 or the TR224 would only gain my 15RWHP or so. I don't mind going to a bigger cam as long as I wouldn't lose any low end power. Also as he was saying, the gas milage really wouldn't be effected that much, as long as I can keep my foot off of the gas pedal

 

For what your goals are (not HP but low end Torque) I would stick with the TR224. If you go bigger you're gonna give up low end torque. I would try this setup first then if you decide it isn't enough get heads. JMO

 

I don't ever plan on doing heads. I've come into some money so maybe I should think about just supercharing it? Of course that would pretty much mean everything would be stock, but I would still do the custom cat back for the sound.
