The G2 has a more agressive profile so you will use springs up quicker. How often depends on how you drive it and the springs you use.
I hope you have a line on a used one. The $1295 for the kit on LG's website is outrageous. TSP has kits from $599. Their 224R or 225 have similar specs. You should also check out Futral. Their cams are cam motion grinds and make good power. The F4 is closest to the G2.

For LSA, a tighter lobe will start you into your paower sooner, but you'll stay in it for a shorter time. The wider LSA will start a couple hunder RPM later but you'll hold it longer. Talk to whoever's cam you decide to run and they'll help you decide.

Yes, clean is emissions. I don't have to worry about that here...yet. No tailpipe checks, but they do still have the roadside monitoring stations.

 

I wasen't going to go with the G2 G2 kit... too much money. I was gonna go with these parts... what do you think?

G2 G2 Custom Cam (224/224 580/580 114)
Comp Cams Hi-Tech Chrome Moly Pushrods 5/16 7.400
Comp Cams LS1 Titanium Retainers For 26915 & 26918 SPRINGS

Though if I went with the G2 G2 kit I could get the kit and have it installed for $1600...

Would you say the 114 would give me a better power curve than the 112?

 

This is the trend. Peak horsepower will be near the same give or take only a few, but with an increasingly narrower lobe seperation angle you do get more overlap and more torque. The only reason that big cams stay around 112 is to promote better idle quality. I'd like to see more LS1 cams ground on narrower LSAs, but then again, I bought a 114 lobe center line cam.

My opinion is less duration and tigher lobes is where it's at for street usage.

No, just stretch it out a little, but you'll hit it later. Just depends on what you want. Like I said, talk to whoever you get your cam about that. I know futral does theirs ground advanced. That makes a difference too.

By my calculations thats over $800 and you still need some springs.

I'd have to agree with Ben. There are guys running some custom ground 108 & 110 LSA with short duration cams. Totally streetable, great curve, power like a much larger cam all in by 6k rpm, and they're clean!!! If you go this route it requires the research I mentioned before. That or you could just clone someone's specs. If you do go custom, definately go cam motion.

The Aussies have been running short duration, tight LSA cams for a while.

 

Last I heard, the comp lobes had greater .100" duration for any spec at .050" than Cam Motion did. Meaning their lobes should make more power for any given duration at .050" lift. They also spec'd a turbo car for a friend and got his suggested grind way off.

Ooops yeah so like $1015 shipped with Comp Cams 26918 springs. Still better than $1200+.

What do you mean by cam motion?

 

Hmm, most folks seem to be talking about the cam. Are you certain you will have to pass emissions. Most states have 5 years of new car exemption. So you may have to pass emissions but not til 2010. So you can run what you want until then.

Now states do vary so go online and check your state laws.

From what I know OBII cars and up don't have to have a sniff test. All the 97+ Camaros, etc don't have a sniff test.

 

That is very state dependent.

In Republik of Kalifornia OBDII cars have a sniff test, but cars newer that 5 years old have no test.

In Nevada (LV and Reno) OBDII cars have a sniff test, incl new cars.

In Az OBDII cars have a ALDL test and need to set no codes and have all the monitors completing (well all but one). But again new cars less than 5 yrs old are exempt from testing.

Each state is different.

BTW, my LS2 402 passed in AZ easily on the ALDL test. And that was with a cam much larger than being discussed here.

 

Yep just have a computer hook up. From what the guys were saying they don't even do that to their 2000+ cars (lazy I guess). There should be no sinff test even after 5 years from what they are saying.

As far as it goes it seems I will have to get a bigger cam. As Todd was saying the LS2 has a pretty decent cam in it already. Going to a TR224 would only gain me around 15RWHP. Looks like I'll just have to stop by tomorrow to talk to him and see what he suggests to reach my goals.

 

IF you're going bigger....f13

 

I think I may just go with the shops custom cam package. I can get it for $950 and he said it would put me 395-405RWHP. I can choose whatever cam I want, though since they were selling 2 of each of their cam packages at that price they thought they would offer it to me. I could have got the specs, but even if I did I had to promise not to tell anyone. I'm gonna go talk to them in an hour or so and see what we can come up with.

 

I would buy no cam with out knowing specs.

 

Well ended up going with Mike's cam. Pretty big cam, idles very nice though (got to hear a LS1 with it). He said there wouldn't be any low end power loss, and will pull 1800 to about 7000. It will give me my 30RWHP, maybe alittle bit more. I'm not allowed to give out the specs on it. I know even by making a custom cam just like it they wouldn't get the same performance out of it, but I promised I wouldn't tell so I wont. Got the kit for $900 out the door

We are also going with some other stuff. As said the SW LT's/cats, custom Borla cat back, K&N CAI, dyno tune BMR swaybars, B&M tranny cooler and a Yank SS 3600 converter.

I'll also be going with some KDW-2's all around. Though if I can get some Nittor DR's on the back I will get those on the rear. If not I'll have to find a set of 17" stock GTO rims and put some DR's on them.
