flywheel/pulley divability?

SS_Firehawk · 11-09-2011, 10:21 AM

I've been looking at a lot of information regarding upgrading the drive-train. I'm about to submit payment for a set of NST pulley's, and my intuition tells me, that it will work well with a flywheel.

I've discussed my interest in hot lapping in previous posts and I read a lot about upgrading the LSD. This is still my DD and I don't want to get crazy with it, but what are some recommendations that you all might have with the drive train? I haven't seen any posts regarding drivability of the car when upgraded with a better LSD and, flywheel in combination with the pulley's. Thanks in advance for the assistance.

Hmmm. Maybe I'm a minority in this thought? Regardless, I guess a lot of the stuff I purchased for my build so far fall into the minority category.

Long tube headers from PPE Engineering
AE performance Oil Cooler
Just put my deposit down for a Motordyne Intake Manifold
Ordered an AEM CAI
Just ordered NST pulleys through Corner3Garage
Motordyne Xyz Y pipe with Cat is being ordered next week
Tanabe Medallion Exhaust will be ordered next month unless Motordyne comes out with something before that and impresses me :P

It will be like Christmas when I get back home

The Flywheel is a worthwhile upgrade for you here. The only "downside" is when street driving you will have to adjust the to change in taking off. The stock flywheel is heave and carries a lot more ineria than the lightweight one will. The good news is there are probably more advantages to it than disadvantages.

For a car that I track a couple of times a year, I would defnitely do it.

As for the LSD, I would def. do one of those as well. My stock viscous LSD is junk on the track. It's actually crapped out on me just doing spirited driving on back roads. I've installed a few diffs for other guys, the Nismo and more recently the WaveTrac. The Wavetrac diff is probably the nicest that i've ever seen... and i've seen a lot! I would think most any of the aftermarket diffs are gonna be better than the viscous LS that comes factory.

I run a competition clutch steel flywheel (~17lbs) and a stillen UD pulley, it's well worth it.

Drivability wise: the car revs much faster, throttle lag is as non-existent as you can get with drive by wire (im uprev'd as well). Downside with the flywheel is the chatter as the transmission warms up below ~2k rpm. We just have noisy transmissions, which is why nissan put a 34lb dual mass beast of a flywheel in the car to begin with.

I quite enjoy the mechanical menagerie of our vehicle. It's quite unique among cars that are priced for mere mortals. I am excited to hear that it makes that big of a difference. The engine stock seems to hold on to rpm after I release the throttle like dry fruity pebbles on a bowl. I really want to maintain every day drivability.

Wow. Time for me to upgrade. I didn't realize the Nissan flywheel was TWICE the weight

If you are planning on staying naturally aspirated for awhile get the pulleys. If you have forced induction plans sooner than later, pass. Also if you are going to pay for the labor for the flywheel install, might as well do clutch and flywheel since the transmission will be dropped anyway.

Normally I would agree, but with the 370 I would be hesitant to upgrade the clutch unless you actually need it. Once you upgrade the clutch the extra stress on the slave usually causes it to fail. Upgrade the slave and you have the potential for the master to fail. These aren't absolutes of course but it's happened to more than a few people.

I've seen it happen with local Z owners. Makes me sad actually. The worst part is that I see myself upgrading my clutch eventually.
