what do you gear heads think about 268º Tomei cams for the street? too much?

i personally like the rougher idle.

let me know what you think.

It still porbaby won't be as rough as hubby's Camaro--he literally has to start that thing 2 or 3 times to get it to idle. I can't wait to see how he's gonna keep that thing idling in the winter.

I know these cams are going to be pushing it for your basic streetability, but if you ask me, if you're gonna do it, do it right.

 

Sounds fine to me for NA, but as 350zspeedracer said, good luck with cold starts, lol.

Now, 272s would REALLY be pushing it.

 

Just had my Nismo Cams installed. Car idles SLIGHTLY rougher but you don't notice it after about an hour. I personally would like a rougher idle, but this toy needs to be a daily driver as well. Would love to hear from someone who has the 268º Tomei cams in their car!!!

 

IF I were going to get cams, I go with an aggressive setup. All that money for labor, I wouldn't mind a rougher idle. Gives the car a little character, announces your presence with authority!!!

 

What are gains from these?

 

what are the nismo cams, 268?

 

262º

 

what is the degree lift of the stock cams?

 

rough idle as in the car wants to stall? Is this even with raising the idle speed?

 

I think the stock ecu can compensate up to 272's, but like with everything you gain something you lose something else, namely torque down low, so you have to decide what you want out of your engine.

 

As Verno mentioned with down low torque, I can't sacifice that for some more up-high hp, I would rather get both tq & hp increase with the mid cams... 264's...

i never thought of that, maybe 264 better suits me then.

thanks for your input.

We up'ed the idle 100rpm, advanced the timing 2º and adjusted the A/F. The idle is fine but you can feel (or see) the engine shake just slightly at idle. Didn't do that stock. BUT, nothing like cars I've had with nasty cams where the engine is hunting around looking for an idle. I would have prefered a rougher idle myself, but didn't want the pay-offs that come with it.....

 

268's should be fine...I had some 280 degree cams in my old car, I loved it, idled at 1400rpm's with a nice lope to it. What are our stock cams duration?

 

At what duration? You cannot talk about lift without talking about duration, and vice versa

What kind of scale was the lift acheived on? I know its nothing people like to hear but without knowing all this info, its really completely useless info.....

Over the course of the next few months, one of the things we will be doing is actually testing the various cams on the market for this car on the same bench, to see what they really are, and more importantly, to see how they compare to stock, as well as to each other.

Guys, the idea is to try and bacome a smarter consumer. While we love selling stuff, one thing I have learned both as a vendor, a well as a consumer of specialty car parts (I was buying parts for my own cars LONG before I ever became a vendor) is just because someone sells it, does not mean its worth buying. For all we know at this point, a NISMO cam may equal a Tomei cam....

 

You guys should post pics of the cam profiles so it would be easy for people to get an idea of what everything meant and to see how different the cams were (plus it would look cool).

-D'oh!

 

Forgive me if im wrong, but doesnt 268 refer to duration, whereas lift is measured in inched/mm/etc.?

 

r34racer - yes you are correct - got a bit ahead of myself there, since I see questions like this posted all the time here, and have replied with the same questions a number of times - people jsut don't seem to care about learning what everything means and what the differences are.....

 

And, let's not forget that 2 cams with the exact same lift & duration can have entirely different profiles......

Adam, I'm guessing, but is that what an "amrekt" does?
