Go with the stage 2 if you do city driving. Peak power up top is the only thing you will get with a stage 3 at the cost of some bottom end tq. You will enjoy more power under the curve daily driving with the stage 2 cam. The stage 2 will still have a very noticeable chop to it. Peak dyno numbers should never be the way to choose a cam. Picking a cam that matches your driving and purpose is always a better idea. Cams are always a compromise. You can have dyno queen power and no fun in traffic or more usable power for the street and still enjoy the car. I have had big cams in my vettes and I have had baby cams in my vettes. I have found for street driving and all around enjoyment the stage 2 type cams are better. Best bang for the buck to me was a mid level cam with a 3.90 gear swap.

For sure sounds like a good plan. I'd rather be safe than sorry.
If it were me I would leave the heads alone unless you’re trying to make as much hp as you can. A new set of heads isn’t cheap tho.
as far as the cam I just had the BTR stage 2 put in my m6 ls3 and I’m happy with how it drives. Can’t speak for the stage 3 but I went stage 2 to retain some low end power vs the stage 3. I don’t road race or anything but I really like the low end torque for spirited driving. On stock heads it made 465rwhp and 442tq… not huge numbers but that’s also paired with 1 3/4 headers and a catted x pipe. I would have made higher peak hp with 1 7/8 headers and catless x pipe. The car drives prob 90% like stock.

That's really awesome info. Was it the regular stage 2 or the version 2? Just curious. I'll have the Kooks 1⅞ with catted. I went catted because the person who had it before me put on corsa extreme and I thought that maybe if I did a catted x pipe that it might not be so crazy loud. I like loud but I doubt the neighbors really want to here that too much.
Yeah sounds like I'll be staying stock on the heads. Maybe if one day I have the money to do alot more I'll throw on a magnacharger and then heads for the extra flow.

It wasn’t the new V2 that recently came out. I’ve heard it’s a great cam but it was too new out when I got mine and there weren’t enough reviews on it yet so I went with the previous version. Someone correct me if I’m wrong but I believe there’s actually been three different stage 2 versions, maybe not. But the one I got is def the one before the v2 that just came out.
I went with a catted X pipe and I’m glad I did because even with cats the smell is pretty strong. As far as sound I wouldn’t mind if mine was a tad louder. I’ve had a set or Borla Ataks on and now I have the factory NPP mufflers. Still sounds really good tho, cats actually clean up the exhaust note some in my opinion, it’s not as raspy.
I went with BTR stage 2 on my M6 GS. The drivability is excellent which is what I wanted. Stop-n-go traffic is no problem at all and the chop is very nice. I wouldn't want to go any higher.
Bigger cam w 15 yo lifters?
idk if that’s the best idea.
If it were my car and I was going to do a cam
Id go w new lifters.
then of course heads since coming off already
or just do a supercharger for few more bucks

I thought about that, seems the guys at the speed shop aren't worried about that since the cars only got 17xxx miles. They are gonna check out the cam when they pull it and make sure it looks good.
And, what are you going to do with your original OEM cam after it's replaced with an aftermarket cam ?
Well, that's an easy question to answer ... slap it up on your garage wall ! . . . .
That's pretty freaking cool right there.
So went with the btr stage 2 v2. Trunion upgrade, power bond damper and the kooks. Should be a decent fun set up for a while. Left the heads alone. Shops gonna get me in the 16th so ill have it done by the 19th or 20th of this month. Pretty excited I tell ya.

Good parts selection ..
BTW ... Have them pin your new harmonic balancer when installing it. If you ever do put a supercharger on the car in the future, you will be damned glad you had the balancer pinned beforehand.

Yup I did forget to mention that part. The guy said he usually pins any manual car even if they arent supercharging it. So yes that's getting done also. I'm definatly gonna do something cool with the cam too. Maybe mount it like you did or think of something different. I always hate stealing others ideas but that mount on the wall is nice.
Are double valve springs required for the Stage 2 v2 cam ? Can 1.8 roller Rocker arms also be used for this setup ? Are new pushrods required (hardened) ?
Yes to double springs. Use stock rocker arms. New 7.4 BTR pushrods.
You're probably right, but it wouldn't hurt to ask BTR what their PR length advice would be running their cam on a stock LS3. The base circle on the cam has to be a little smaller. Depending on how much smaller, it could require a longer push rod.
