Good turbo cam Its finally time to build so the question is who to get the cam from. This is my DD so needs to be streetable. What you guys recommend? Ive got a 70 mm precision turbo, just trying to decide what cam to go with.
Tell us more details about your turbo kit. A/R ratio of turbo? Manifolds, logs or tubular exhaust? Intended boost level? Anticipated rpm range? What's your application? What are your power goals? Auto or manual?
Turbo cams are some tricky beasts to cam correctly and you've left out the answers to 97 out of 100 questions I would typically ask before giving a recommendation. The questions above are obvious ones just to get in the ballpark.

As i sit its a stock ls1. The turbo goin on is a 70mm Precision 96 A/R. A2W intercooler, heat exchanger. Im having the headers built by a friend and will be front mount. As far as rpm range not really sure first turbo ive messed with but prob in the park of 2,000 to 5,800 if id have to say. Ive got 5,8,and 11 pound springs for boost levels. Car is a 6spd w/ 373posi in rear. My goal, id like to see between 500 to 600 rwhp with Cam, boost and tune.
Any cam will work, usually whatever works all motor will work with boost...if u got the cash get a custom grind, if not but a used cam on here and it will work fine since ur setup isn't too radical...good luck

I wouldnt say rich, just dont have kids and family like i do, Oh yeh and they have great paying jobs lol. They mainly have stangs, Goats, and few others. But the half the guys with stangs are running LQ engines with spray, and the goat boys are all boosted. Im the lowest on the poll with HP at 300. They all sittin between 600-1,000 HP.

You don't need that much power to beat them, if you get 450+ hp and dial in your suspension you will be hurting some expensive feelings...good luck man kill those stangs (at least they got smart and put a Chevy in it l)

Just having a turbo laying around is 1 thing, but do you have EVERYTHING to go along with it and do it right/correctly is another? Cam wouldn't be so high on my list right off the bat, but hot/cold side pipe layout, fuel system, intercooler, meth kit, controllers, guages, etc..... would be more inline imo.

Headers are being built, Intercooler, Heat exchanger,BOV,wastegate and other lil things are chilling with turbo. As far as the other goodies ive got to get. And everything will be done right or not at all. I dont have a couple grand just laying around to cut corners. Ive saved my lunch money for a while for the build! LOL
If you're not looking for huge power numbers you may take a look at the LS9 cam. They can be had cheap, drive like stock and are a good turbo grind IMO.
Just remember that they do not come with a cam sensor reluctor in the back so you'd need a 4th gen front cover and cam sensor extension.

I'm running a turbo cam with 222/226 @ 050. Lift is 0.575"and lobe centers are 113/116.
Cam was worth a tad under 50rwhp before adding the turbo over stock but that included slightly tighter head gaskets, stiffer springs and beefier pushrods.
6lb boost was 450rwhp on my old Ls1 with auto. It has a noticeable idle and makes more power everywhere than the stock cam.
Only downside is mpg is down 15% around town and 5-9% on highway. A bigger cam logically uses more fuel (even at cruise) because the valves are open longer.
Guys claiming better mpg on a big cam over their stock cam can likely put that down to a better tune, other mods, and more careful driving. Their big cam will cost mpg.

As stated pretty much anything will work. The LS6 cam is a big favorite. But having said that I remember the 700rwhp 4.8 running a cam out of a stroker. Also I personally know a turbo 4.8 running a MS3 on a 113 and several setups running the EPP FI cam (NA, Front and rear mount setups). You can also look at Speed Incs turbo cams.
