guys, please help me decide

 

they do totally different things...

one will make for quicker engine response and improved acceleration power...

one will make for overall quicker acceleration...

 

If u plan on going FI even remotley in the future, get the flywheel and clutch combo
If u know you will be staying NA get both :-D.

I'd get the clutch w/ flywheel combo b/c it leaves ur options open

 

The car is going to stay NA. and yea, i would love to have both mods but I can't afford to do both at the same time. so, which one will produce a more noticable gain?

 

A light weight Clutch/Flywheel combo will give you more engine response and might also hold more power than stock.
The shorter final driver ratio will increase the car's accerleration noticebly. The only draw back is your engine will run at little higher speed compare with the stock final drive at the same gear same vehicle speed.

 

lighter flywheel will give you a more noticable difference...

you experience it with every shift, and every blip of the throttle...

the 3.9 you wont notice as much with that 60lbs mass of a flywheel and clutch on the other end...

 

THANK YOU ^^

 

you'll notice the flywheel more on first thru third gear and the gears kinda more in 4th thru 6th gear since they have such a small ratio. With the 3.9 FD, it's easier to pass cars in 6th gear which before was almost worthless for passing on the highway.

Conversely 1st gear with a light flywheel becomes crazy fast

 

how the hell do u remember ur account name lol, and id def get teh JWT/FLYWHEEL clutch. im not a fan of the 3.9evo deal..they're out of bussiness anyway...

 

so that 3.9fd is not making hugh difference?? i am planning to get one but still could not make up my mind!! i have heard that 3.9fd is the best mod for na z! please give more info.

 

I'd get a 3.9 if you're NA or even possibly a light supercharger, but not for a single turbo or twin turbo

 

would it be cheaper to install both at the same time?

 

i wouldn't think, except scheduling and stuff. clutch/flywheel is your tranny, and the 3.9 goes in your rear-end.

 

probably not dramatically cheaper though

 

I had the same question. I would love to FI the Z but money doesnt let me..

What clutch and flywheel is a good DD combo and track combo. Thanks guys. Sorry for hijacking 100122923. I was debating on the Tilton combo...

 

tilton is pretty extreme for DD. If you're at all concerned, you might want to get the JWT flywheel

 

Doesn't the 3.9 FD make like .3 to .4 second difference at the 1/4 mile?? I dont know what single NA mod you can get, that can make that much of a difference.

 

Kinda hard to be out of business when i was there yesterday and am having a 3.9 installed by BJ next week! when they get back from tuning their new car.

They arent outta business they are just selling their race cars (350Zs) and buying different cars, and also axed the Intake Manifold project, but they are doing better than ever as for business wise, i see more high end rides in there every day, for the time being they are fine until everyone starts spreading rumors about them being out of business...


also I plan on goin FI with the rev-up motor and 3.9

 

nah not that much. At least not with the 3.9.

People with autos who go to the 3.5 get that much or even .5 sec faster though it seems

 

Nah, i think a auto only gets about .2 sec faster jumping to a 3.5 FD. Theres actually a member here that did it and thats what he reported. And theres a member in g35driver.com that reported close to a full second difference jumping from a 3.3 FD to a 3.9 FD on his auto. Although, that seems a little too much. So im guessing a 3.5 FD jump to a 3.9 FD for the 6mt would have atleast a .3 to .4 sec difference. Lets just be more on the conservative side and say its a .3 second difference, which is still pretty good for a NA mod.
