Now Coz,

YOU KNOW that this is in the wrong forum!

Somebody ban this guy!!!!

 

That looks wickedly cool, I wonder if I want one...eh, I do.

Oh, how much does it weigh?

 

Sounds pretty cool... these gonna work well in combo with a SC or TT ?

That's it, no more parts for you, he he

How difficult is this to do yourself? Do you need special tools? I have access to a lift and tools, and wondering if it only takes a few hours. Maybe somebody can post a 'How to'. Thanks.

 

You have to remove the transmission to access the clutch and flywheel.

To remove transmission:
1. Remove Strut bar
2. Remove cross bar (requires removel of steering/engine mount insultaor/support engine)
3. Remove cat
4. Remove propeller shaft
5. Remove control lever and separate shifter lever
6. Remove clutch cylinder
7. Remove POS sensor
8. Remove starter motor
9. Remove rear member
10. Remove engine and transmission mounting bolts
11. Remove transmission

There are a few more steps removing some sensors but this is the bulk of it, it seems like it would not be hard if you have a lift and the tools, power tools and jack stands to support engine and transmission.

 

I remember reading something about the 2 piece flywheels being inferior. Anyone have any data to support or negate that.

 

Thats it i want one. But i will wait until i wear out my clutch. I cant convince myself to replace my clutch and flywheel while the ones i have still works. But man those are some great prices you WILL be hearing from me for a flywheel and a 300zx clutch in about 6months.

 

You don't need a new clutch for this flywheel...

 

Yes i know that but if i do replace the flywheel it will be better to put a new clutch on it at the same time. Its a pain in the a$$ to removed the tranny and id rather not have to do it now, and then again in a year or two to put a new clutch on. It costs a lot of $$$ to get one of these installed in labor alone.

 

does changing the lighten flywheel have the same effect as changing to a lighter crank pulley? The purpose is to reduce the rotational mass so the engine can rev better?

 

Yes, even more of an effect since it is heavier, therefore more wieghtloss to be had and is directly connected in the power transfer unlike the pulley.

 

Yup, same exact concept

 

At the same time, your revs will drop faster between shifts.

 

flywheels allow the car to rev up faster.. on the track its awesome especially if you have a Supercharger or turbo you get to boost sooner, but when driving around town, you typically have a slightly higher engagement point/play with the clutch more cuz the revs tend to drop alot faster, you have to move your feet alot quicker...

for NA purposes.. i didnt think my aftermarket flywheel was worth the money... but for boost, i think you would like it more...

clutch if anything would probably be the better upgrade so that you can dump the clutch and not fear it slipping....

 

How quick revs drops is also controlled by the ECU, not just the mass of the parts. In this case, the ECU is going to probably keep them from dropping quicker than they already do.

On a Turbo, boost comes from engine load, not so much RPMs. It's why many folks never see full boost in 1st gear, engine never sees enough load. A light flywheel if anything, is going to reduce engine load, and make boost come on later rather than sooner with a turbo.

At least this is the knowledge I have been given... I see so many differing oppinions on things I usually dont even bother to reply, but Im bored.

I agree with boost coming from Load more so than RPM's but RPM's are directly proportional to engin load, correct? What I don't understand, is how engine load would be any different between gears. Different gears effect the transfer of power through the drive train, but do not effect the combustion process (same amount of air in and air out regardless of gear) Now, if that's the case, how could that affect boost? Freeing up unspun weight in the drivetrain though methods such as a lightened flywheel shouldn't affect boost, but rather allow the engine to push boost faster. If I'm wrong, somebody please explain this to me.

 

The only thing I can think of is that in the higher gears you are in the powerband, thus loaded, longer.
