Cavalier FlyWheel

I'm looking into buying a Flywheel for my 97cavalier LS.I heard that it increases HP, is this true?

And how much does the stock Flywheel weigh?


Information about the flywheel is below,I just want to make sure that this is right.

CAVALIER 95-01 A.T.; 4-134 (2.2L)

How hard is it to do this yourself? And what would the average price be at an autoshop to install something like this?

Is there any other items I might need before installing?


Thanks for your help

Fly wheels are for Manual Transmissions.

Automatics have a flex plate.

Lightened flywheels free up rotating mass for quicker revs, but since you have an auto... nothing available.

Yes, that certainly is a flexplate there.

The equivalent mod for an automatic transmission is to get a smaller torque converter. This has 2 main advantages:

1. Smaller converters have less mass, so revs build faster.

2. Typically smaller converters have a higher stall speed, allowing the engine to rev higher at lower vehicle speeds. This feature is best used when an engine has been modded for to develop more power. Often, such mods create more power at higher revs, but oftena side-effect is less power at low revs.

Thankyou both for the information. :-)

So where is the best place to get a smaller torque converter? And is that a hard install?

The only company that I know which use to sell them got rid of their 4t40e auto inventory on Ebay not too long ago. We've got one of their stalls (2,800) in our fully built sunfire.

There was one listed not too long ago on e-bay, but I know its gone now since I directed a buddy to it.

Other than that, I have no idea where to get em from. Is it hard to do?

The hole transmission needs to be dropped out of the car, along with the starter. It attaches to the flexplate from side of the flex plate towards the motor.... and since your not boosted or anything. I'd say its not even near worth the cost/benefit.

Stall converter company was Yank... forgot to add that. I think they have different level as well. 2,800 - 3,000 - 3,400

I'm not looking to turn it into a turbo overnight or anything like that..but will it do anything for now at all?

I do want it to go faster...can you tell me some upgrades that I can do so in the near future I know what to look for?

This is just something that I would like to do when I come into some money that's all :-)

Honestly.... look into other mods. For what your going to pay for the stall converter and someone to put it into your car, you'd be better off trying to find a 2.4L and trans drop out and have someone install that.

Alright, I guess I'll do that then. Thanks again for all the information you provided. ;-)
