Hi there so basically I'm planning my Camy's build. I have a Ls3 motor and so far this is the idea.
Edlebrock E-Force Supercharger
Flow Master Cat-back
Some bad ass headers (no idea which I should use)
CAI Cold Air Intake
Thinking I need to update my cams/lifters/pistons etc any ideas?
I want this to be able to beat any Mustang on the road still has to be street legal and smogable. Any ideas you can give me i'd greatly appreciate thanks guys!
It sounds like you have the right idea. As far as headers, you can't really go wrong with any brand out there as long as you stick with the name brand types. This car has a lot of room under the hhod and fitment isn't really an issue. I recommend going with a 1-7/8th primary header made of T-304 stainless steel. If you're planning on big power, then you may wanna step up to a 2 inch primary header. Since you are planning the type of power that requires upgraded internals, go with 2 inch. TSP is going to be your best bet on price and quality for 2 inch. If you stick with 1-7/8th then BBK, Kooks, ARH, JBA, OBX, Stainless Works/Stainless Power, and several other brands are all good choices. And they will last. If you wanna stay smogable, then get a catted style connection.
You will want a mild to moderate cam. TSP, Comp Cams, Crane Cams, Trick Flow, and other companies have great choices for either off the shelf or custom cams. The cam should be your last choice tho. Because it will be the most critical part of your combination. The right cam can mean the difference between a well put together engine and an engine that is not efficient or optimal in hp/tq. Some companies offer head and cam packages. The heads on these cars are quite sufficient. But with your list, you might as well get some ported or aftermarket heads while you're at it. And remember, most of the companies are very knowledgeable when it comes to cam profiles. So take their advice. Tell them the combination you are going with and what your end goals are. They will do their best to match you up with the best possible combination. Make sure you stick with the best known companies.
The E-Force supercharger is good. But I would go with a better supercharger. For big numbers, you're probably better off with a Procharger, Vortech.Paxton, or Magnuson. From what I remember, the E-Force was more for stock to mildly modified engines. I don't think it is a great choice for moderate to heavy builds like it seems you are planning.
All tuners are pretty good for stock cars. So for now you can get whichever one you fancy if you just want a boost in performance. No one will be significantly better than another. Once you are ready for your build, you will have to either go with a brand your dyno tuner recommends, or go with whatever brand your supercharger will come with. Most blowers come with a package that includes a tuner. And they'll have you take the package to anyone on a list of specific shops for the install/tuning so as to keep the (optional) warranty. At that point you could just sell the tuner you have. But it does seem that Diablosport and SCT are the more well known and more often used tuners.
And if you're going to do your pistons, then you also might as well upgrade your rods, crank, and bearings. Matter of fact, you might as well go ahead and look into a stroker kit if your budget allows. Because the engine will have to come apart anyway to do the pistons. Might as well do everything all at once. Including getting the block machined.In the end, you will have a rock solid brand new engine that should be able to support over 1,000 hp.
This type of build takes a lot of time to plan. So don't rush in to anything. Take your time, do some research, and ask questions. If you don't understand something or are unsure of something, then do not go forward until you do understand. Most people will gladly help. Check out some other members builds and follow them along to see what they are doing. In the meantime, start with a few mods at a time. A CAI, exhaust, and headers is the typical starting place. Or you can dive right in and start off with a supercharger. There are vendors with specials offering blowers with install and tuning for around $6500-$7000. And they are pretty reputable and dependable. And then later you can upgrade your headers, intake, etc.
