i have a 06 350z with 31k.. only mods are exhaust and intake..i was looking at gettin a set of camshafts.would that be ok to install on a stock engine and be daily driven?

 

won't that only make the engine stronger? = better?

 

For you right now there is no need. The camshafts and heads on the revup provide more than enough flow for your current setup. Invest in a spacer, MREV2, some headers then maybe some cams.

 

get a tune

 

i was looking at getting brian crower valves and valve springs with cams. would that be something practical ?

 

Cams, like headers offer very little bang-for-the-buck. What NoWin is try to tell you is don't waste your money for them on a stock setup.

 

yea but i want to be able to race my car alot. so i wanted to upgrade some of the head for more strong parts that can take the abuse.

 

I'd be willing to bet you that 95% of the Zs that go to the strip, track or autocross are on 100% stock internals. Failures are almost non-existant. The VQ is a very strong, reliable engine. The FI built engines, naturally get beefed up internals.

It sounds like you've already decided to do cams, no matter what logic we present. There's nothing magical or extreme about them, so sure, you can drive them on the street, daily.

 

It sounds like you think there is something wrong with stock cams structurally. What dave is trying to tell you is the stock cams with almost definetly not be the weak link that would break.

 

so are you saying that i will not get any extra power from cams, intake exahust valves, and valve springs?

 

Nope, not much. Do some research and you'll see that people who have spent thousands of dollars on cams and headers have seen very small gains. You could get more power just by spending a few hundred dollars on a MREV2 plenum, high flow cats and a tune.

 

thxs alot for the input davesZ.. u got me thinking about the MREV2.. can u use that with a aftermarket plenum and a plenum spacer?

 

only get the cams if you plan on going FI

 

If you have a Revup engine, I believe the MREF2 is the way to go. Spacers or aftermarket upper plenums don't provide any additional gains.

If you have a non-revup engine, the MREV2 will provide good gains, and a spacer will provide a small additional gain.

 

uh, no

to the OP - what Dave is telling you is partially correct. Cams are not your cars current bottleneck. It would take a substantial level of mods to have your stock revup cam shafts prevent a bottle neck to power. You would have ALOT of parts to buy/install/tune, and ALOT of money to spend before you should start considering cams

 

no

a spacer us used to better even out the airflow with a stock plenum. It is not for use on an aftermarket plenum

 

for my 06 what would be better.. MREV2 with AAM spacer or the Kitnex SSV manifold?

 

with all due respect, you really need to search the forums and read various threads - any info you could possibly need is listed
