cams/head options for an n/a sc?
So with the car being a long term project. Id like to keep it n/a for now, and when the time comes, or the motor pops, go na -t. For now I'd stilllike to add some power. Being a non vvti car, it seems damn hard to find cams. That and i was hoping some of you could point me towards a better breathing head, and a nice set of ca.
P.s yes I am aware that the forum has a search feature

All the tech threads are dead and old(at least the ones I find.) Reading them has helped some, but some current info would be nice. Im finding nothing as far as heads, but it appears a gte head wont increase powwer and will be a pain in the ****. For cams what I really want to know is what set (if any) will boost power, and still be useful if I go turbo.

There are very few things you can do with the n/a 2JZ to make any useable power that your going to notice. Building an n/a 2JZ is going to cost you the same if not more than going na-t or doing a swap.
My opinion, and Im sure 99% of CL/SC owners are going to agree with me, dont waste time or money trying to build an n/a 2JZ. These engines were built with a turbocharger in mind and that is where they are happy. Search google for n/a 2JZ's and your going to come up with a very short list of actual builds that didnt cost $10k+ that can actually compare in performance to what a $3k-$6k na-t build would.
Im not saying it cant be done, but in the end, and built n/a 2JZ with just heads and cam is going to suffer horribly against a fairly low boosted na-t and cost the same if not more. If you just want to do heads and cam and stay n/a, look into an LSx swap. A few of us have already done them, and if you know how to source parts, its not too expensive.
Other than that, just go na-t or GTE. Trust me, you will spend less trying to make useable power, and be much happier with the power you can make @ 9psi with stock compression/fuel/cams/etc.

OP please theres no head/cam packages for GE, please do regular engine performance research first before you make threads like these.I'm willing to spend a few minutes of my life explaining this so hopefully next guy that sees this wont ask again.
Cams for n/a have usually a low lobe separation i will not go into explaining what it is if you want google it. Turbo motors have higher lobe sep on cams.
Cams for n/a usually have lower duration and n/a cams higher duration. Lift usually dosent matter. So you will actually loose perf with n/a cams if theres such thing for 2jz. Please save your money and go na/t stock Ge motor should never pop if you mantain it and you can go na/t with current motor with simple tt head gasket/arp stud upgrade.

So until there is definitive proof (dynograph) showing the loss in tq/hp from adding a 3'' exhaust on a stock SC vs. stock exhaust on an SC, I dont think that is viable information.

why in the world would you make such suggestion? Do you know what 3" exhaust would do to a 2jzGE? He might as well take the exhaust off the manifold and loose trq/hp that way at least its free.

While I do appreciate the cam info, would it kill you to wash out the sandy vag and either answer questions or stay outta threads, rather than posting "do research on something that isnt out there" It's like half the people that post in here don't understand people new to these cars are going to have questions

You guys will have to excuse my ignorance, but I am from the mustang/f-body world. When I think heavy car with a popular motor, I think of n/a mods that often wake them up due to them having a large aftermarket. Looks like she will be staying n/a and stock/slow until I move and settle in.

Cam gears are not worth the money unless you want eye candy, they do not yield much power. As far as camshafts, some have had custom ones ground, I believe Titan offers a set for the NA head, as well as BC. Not 100% sure though. I've mentioned before, lightened pulleys are just mainly for eye candy, it's not going to make a world of difference in power gains.
As far as the GTE not yielding much of a power gain is somewhat true. Many don't swap to the GTE head for a power gain right out of the box. People use the individual coils to their advantage as well as the extra room gained with the deletion of the distributor cap to allow for turbo and coldside piping fitment. The aftermarket support for the GTE head is a plus.

Uhhh noo not true. Also if you had read the OP's original post you would notice where he says...
So if he put a 3" exhaust right now he wouldn't have to buy one later on down the road.
OP like I said, just stick with intake & exhaust, till you have the monies to go turbo.
