Hey guys i know im beating a dead horse a little but i just bought a set of lg longtube super pro 1-3/4'' primarys and 3'' collector w/ high flow cats. and x pipe. want opionions on what cold air system to use and what cam to use. car is completly stock right now. i was told that with the super pros the gains would be much better with the cam over the steets. it took me 6 months to break my promise to myself not to mod. well im bored of the cars power ,
also i would like opinions on whether i should even cam it or just headers and cai. car will be taken for a tune when done. will the headers,cam and intake cause drive train issues. car is street driven and i do not speed/power shift the car just love to feel the torque through the gears and love the sound of a nice cam. Oh also the car is a 2004 z
Thanks guys!!! i have learned alot here over the last year great forum

Once you install an aftermarket cam, you kind of cross a threshold. You can minimize the impact by choosing your new cam wisely. Think hard about what your goals, and tolerance level will be, now, and in the future. You can make incredible gains with a cam change, but they come with a price. If you go big, expect your car to have running issues, and "stinking" issues from a big overlap. If you want to go FI down the road, a big cam will cost you boost. If you go middle of the road with your cam choice, and stay within a LSA of 114 or higher, it'll be easier to tune, and work great with FI, all with very minor sacrifice if it remains NA. You need either a complete cam kit, or at the very least, better valvesprings, too. A cam like that won't have a huge lope, if you care about the sound, but it can have much more lope than stock. Good luck with your decisions, and enjoy that beast!
What is your end goal for the car? Where do you drive it and how often? Is it tracked often? Drag or road-course? Lay out what you want to do and it will help with cam options...
I will definitly change the springs if i go with a cam. have no intentions on FI and only want to go as far as i can without getting into other problems, just want a nice sounding torquie steet machine. i have had my share of drag cars / prostreet cars ect. and know how the mod. bug works. this is all i want to do to this car, so cam wise a nice sounding cam that will give me another what 15 to 20 horse at the rear. would like to see around 400 rwhp with the cam , cai, headers and tune am i in the ballpark
thanks

i am looking for exact cai, and cam brand/sizes guys have used with headers

Yea you're in the ballpark. Most Mild to mid range cams will put you in the 400-410 whp range. Some guys see between 420-430 with large cams but experience some drivability compromise.
For all out performance you can't beat the vararam B2. For a great all around cam (nice sound and power under the curve) I'd recommend our SNLv3 or a custom XFI 224/230 113+2. Let me know if you have any questions, Chris
got my lg pros yesterday , i know allot of people on here have said lg streets are the way to go. Whhen i called lg the guy he talked me into to pros saying that if i go with a cam down the rd. i will see much better gains and i thought though our conversation the collector on the pros were 3'' and the streets were 2-1/2'' but after getting them and the lg sales book with it both have 3'' collectors the pros x pipe is 3'' did i pay $600.00 extra for the 3'' x pipe and will this hurt my tourque on a stock engine. is there any other difference between streets and pros and is he correct about the cam i am running stock ti exaust

the pros have a race styled merge collector where the streets have a 'regular' style collector as well as the 3in X pipe. an internal feature that makes the pros a bit 'better' for every horsepower counts cars. i didnt' feel like it was worth the extra money, though, over the streets. that being said, you wont regret getting the pros. they are, after all, the best LG offers.
I went with the Torquer V2 cam from Texas Speed. 232/234 595/598 114 lsa. I have TPIS long tubes, hi flo cats & X pipe, Halltech Venom CAI Its got a nice lope, not too much, but noticeable. Dynod 411/380 I have no issues with drivability.
Something you may wnat to consider is either getting full roller rockers or upgrading the stock rockers. Hinson Motorsport can help with that. $200. and you get new roller bearings, trunions and nuts.
I like the new custom ground EPS cams. They are very easy on springs and are quiet in terms of valve train noise. Call Geoff and tell him what you want. They are are ground off a Compcam blank
The tried and true LPE GT2-3 is nice too for your car but will not lope.

You earlier said you were considering LG's SuperPro, which is quite different from LG Pros. I have the Pros, one of the early sets made by Borla, and love them, but I believe the "Streets" are almost as good, and alot cheaper. Whatever, you got great headers, and I recommend a Vararam for your CAI. Not great on the dyno, but the best real world gains, IMO. Wait to tune until you reach a modding plateau, if possible. Also, the cam recommended by Pre-Z06 above sounds like a good cam. With headers, CAI, that cam and springs, then dyno tune, I believe you'll be around 420RWHP, and 390-400 TQ. At this point your clutch may start to be an issue, but I'd use it until it starts sticking to the floor between shifts. It might be the beginning of the end for your clutch, when you dyno tune it. The stress of turning the rollers is where my original clutch gave up.
