about week ago got jwt flywheel installed at Crawfordz(tn) and days later had headers/cats/plenum as well.
Great parts and even better service. Doug and the guys in the shop were very attentive and professional . thanks to them.
now about the car, it feels way way faster and sharper.
based on my initial experience,i highly recommend.
regards.

 

the flywheel can be mated with stock clutch??

 

jkoc

in fact i had the flywheel/clutch(jwt) installed.
but i think you can install the jwt flywheel with the stock clutch.

Glad you like all the parts. Now let us know how it does on the track!

Yes, the JWT flywheel works with the stock clutch. The JWT flywheel is the same dimensions as stock, so it should work with any clutch that follows stock dimensions also. Many people have also used the Nismo clutch with the JWT flywheel.

 

How much for the headers (cost and install)? I am looking to do these later this summer.

 

does upgrading the clutch and flywheels really help that much?? im looking to make my z much quicker, but running out of ideas... wanna stay NA for now..

 

indeed i think it will. the jwt combo is a compromise, better than stock but ok for daily drive. you may ask others about the tilton , which is lighter and more aggressive.

A friend of mine just had her tranny replaced and while it was out she did the JWT flywheel/clutch combo and absolutely loves it. The JWT combo I believe is 14 lbs per piece and results in an overall weight loss of something like 30 lbs, which included the 13 lbs. of rotational mass lost with the flywheel.

I myself will probably do the Tilton street combo because:

1) I'm nutz.
2) It saves a ridiculous amount of weight.
3) All the videos I've seen it sounds soooo awesome.

 

can you guys tell me more about the tilton set up? any pictures..specs..price? does this make the clutch much harder to press in? what about shifting?

 

If you're seriously considering a Tilton, you should definitely drive one before purchasing it. They make a huge difference in acceleration, but they are also a huge pain in the rear for daily driving. A buddy of mine has one. Revs like crazy and the car accelerates *much* faster. However, the clutch barely can be slipped at all, so it's more of an on/off type of system. Not good for slow, smooth starts. Great for hauling rear. For that reason you should really drive one yourself before buying one. You might love it; you might hate it.

 

The flywheel is indeed about 14 pounds (compared to the stock 28 pounds). I believe the JWT clutch is actually about 20 pounds, which is roughly the same weight as stock. The Nismo clutch is maybe a couple of pounds lighter than stock (18 or so). I believe it was Jason@Performance who weighed them all and posted the results quite a while back. I've heard someone say that JWT originally was just using a 300Z clutch, and then they later came out with a dedicated 350Z clutch. However, I have no idea if that's true and what the weight differences might be (if any).

 

Yes, any lightened flywheel (14 pounds or less) makes a very nice difference. If you stick with something like a 14 pounder (JWT) you get a nice acceleration increase and easier rev matching, and it's still very easy to drive on a daily basis. Great compromise. Get something like a Tilton kit, on the other hand, and the performance gain is *dramatic*, but at the cost of daily driving. I've also read posts from many people who have gotten the Nismo flywheel (about 21 pounds), and they say it's a little quicker, but not too much. Pretty much feels like stock since it's only a little bit lighter. Not bad, but a 14 would be better.
