Hello everyone. I have a 98 Z, with about 70k on it for miles. Last spring I added the normal quick boltons, magnaflow catback, lid, and SSRA (made it myself, but its the same idea).
This spring, before my clubs dyno day, I plan to add some pacesetter coated LT's (supporting vendors insert plug here), have the pcm reprogramed to match. The part I am debating, is would it be more effective for a street machine to add a streetish cam with the current heads, or an MSD ignition system? I figure I have a little more than 1k to throw at it, the headers would be half that, and I was figuring on about $200 for the pcm reprogram.

any suggestions on what the other $300 should go twards, or is a LS6 intake more of a worthwile route to go...

 

Three hundred may be enough to cover the cam itself, but not enough to cover the additional expenses the cam brings with it. The MSD ignition would not be a good way to spend the money either in my opinion. I would go with the LS6 intake.

 

what would you do with the cam? rods, springs, and stuff like that?
i saw that texas speed has a package with cam, and other stuff, they say everything you would need, for 540. that is pushing the budget, but if it will make a huge difference, is doable. I know there is no way I can afford to do heads at this time.
Ok, $500... cam package, msd, or LS6 intake?
with the other mods mentioned, any guess what each option will add for power?

 

considering the stock ignition systems have supported many many 400-500rwhp combos on the board...there is NO reason to worry about upgrading that yet.

definatly go with the ls6 intake, and maybe try to get a ported TB...some places do them for $50-75

 

LS6 intake before the cam IMO.

If you DIY and bought used , you could pull off a LS6 cam swap.

Here is something to consider, your sig doesn't say but if your car is an A4 then get a looser converter. You'll dyno lower, but run quicker.

 

used LS6 cam? how would that compare to say, the 224R from texas speed?
certinally not saying you are wrong, but im curious why you would suggest the intake over the cam. I thought cams usually net 40rwhp, whereas the intake is good for 10... but i am certinally no expert. thats why im asking for suggestions.

The car is an A4. what do you mean by looser converter? higher stall, say 3200?
im trying to keep it streetable. the wife has to drive it from time to time as well.

 

Mild cam. The MSD doesn't do much with a coil-on-plug ignition system.

I'm using the stock coils if it makes any difference.

 

A good 3500 stall is very streetable, will add more pep than any other mod for the money, and will shave 5 to 8 tenths off of your 1/4 mile time.

 

Yes, get the intake first. I believe in starting at the beginning as in doing the major supporting mods first. Its a building mod. Ya, its 10 hp on a stock motor, but will be worth more with a cam and possibly even worth more with cam/heads until the point where you've maxed it out. Unlike a pulley that is the same gain no matter what else you do.

I'll even go further with starting at the beginning. Can you hook with your current power? If not, look at suspension mods. Whats the point in dynoing 400 whp if a 350 whp bolt on car is going to hook and leave you behind?

Used LS6 cam because you can get them for $150 or less and the springs for under $60. Can you buy the 224R for that? Power output will be lower than the 224, but for $300 you said you'll have you're still shy of what you'd need (push rods and springs at a minimum) plus you're still probably short on buying the actual cam.

Looser/smaller converter. Yes, a "higher stall" for those who don't know any better. The majority of A4 LS1's run ~.5 sec quicket ET's with this mod alone. I'll bet an "stalled" A4 is more driver friendly than a 224 cammed LS1 w/a $200 tune. A reputable mail order tune is $250-$275 once you figure in shipping and then it is a guesstimation so you will have some surging.

 

sounds real good.
any idea what used ls6 intakes go for, and where, aside from fleabay, can that and the ls6 cam be found? sounds like if i can get both used, i can do that cheaply... and may even end up with the converter in the end.
what suspension mods do you suggest?

 

NOt to steal a thread but what are the specs of the LS6 cam.

Re'

 

i really dont know.. but i would imagine that you cant use the ls series cam in a lt series motor...

 

how about this intake..

says it flows better than the LS6..
can that be true, or is it just typical nonsense
I like the idea of it being aluminum as well. that may look a little better on the car than the black plastic one.

 

Look in the sticky at the tpo of this page.

 

And it'll soak up heat from the heads to heat your incoming air and slow you down.

IMHO the aluminum intakes are a pretty factor for show cars.
