I got a b20b with gsr head, 11:5:1 compression. should I use a stock flywheel or something different. Not sure if i'm going gsr tranny or b16, also let me know what tranny you guys on running.

 

i am running an ACT light wight flywheel with stock B16 trans

 

How light is the flywheel?

 

i have a b20 with a 7 pound flywheel with ls tranny. i would go with a ls or a gsr tranny

 

your n/a right? When buying the flywheel, Do I get one for a b20 or do they all fit b series.

 

Fidanza aluminum. 7.4lbs
All B flywheels are the same.

 

12lbs not too extreme B16 trans has shorter gears then GSR...and i believe if you put a 4.7 final drive it makes it shorter then a JDM Type R with the 4.7...i believe not totally sure...

 

x2

this is also a great FW to use for the cost and performance.

 

i have heard a few horror stories about those two piece flywheels separating. I like to stick to a steel or chromoly flywheel just because of the durability. but hey, everyone has their own opinion!

 

Do you have any links to the "horror stories"? What was the cause for seperation, manufacturing defect or installer error?

I would like to know because I have a Fidanza LW FW and don't want to put it on my car if it's going to separate. I did a lot of reading and research before I made my purchase. I haven't read any negative articles about the 2 piece. Other than some people complaining that it is too light.

If they split apart that frequently, one would assume, they wouldn't be able to sell them as street legal units. I didn't see any "Not For Street Use" warnings on any of my Fidanza parts. I do however see a sticker that indicates that they are SFI Certified. Not sure if that means much for a street car but it must account for something.

 

Don't be scared. It's a great unit from a durability standpoint and the fact that the clutch surface is replaceable is unbeatable. I think new rings are like $45...

 

Ok, so It looks like i'm gonna go with the fidanza light weight flywheel. Anyone have any good links to find this one.

 

Ebay, lol.
Unless you find one in the marketplace for cheaper.

 

i am running a act lightweight flywheel, 11lb. for a street car i think it is better to have a little more inertia. if you were boosted or drag car, then maybe the flywheel would be parasitic inertia, but in a all motor street car, it seems to benefit to having that little extra flywheel weight to carry the car into the next gear.

 

How many pounds is stock flywheel?

 

I just weighed my F22 flyweel and it's 17lbs. 2oz. B20 probably isn't much lighter.

 

yeah i have had my stock flywheel come loose...lol the ring gear came loose on it and i would push start my car for a while...but that is why i got a light weight one...

 

Oh wait a minute. You don't want to be able to rev your car like the guy in that Honda commercial revving the F1? That is my goal for throttle response vroom-vroom-vroom-vroom-vroom-vroom-vroom...lol

 

Has anyone had the machine shop lighten their stock flywheel. Whats wrong with this idea?

 

I have heard of people taking some off the stock flywheel, but I don't personally like that idea. Takes away from the stability and you really couldn't take off enough to make much of a difference without making it a hazard kinda. The stock B series flywheels are 18lbs. I would recommend one that it around 10-12, less than that will make shifting tough at times. I had a 11 lb one in my integra and that was great for all motor. I am getting one around 10lbs for my del sol all motor.

 

if you DD the car or do alot of city driving stay away from the lighter FWs, much more of a pain in the dick to drive. a 12-13lb one is IMO the best balance of the 2.

 

Truer words have never been spoken. (Term of speaking of course).

 

THat was some good *** info. THanks fellas.

 

the stock b16 flywheel i have here is 18.2lbs. if your car is a street car, i would run at the lowest 11lb, and up. between the stock and a 8lb. i would run the stock.

 

a well known clutch company used to machine stock flywheels years ago and sell them. i have had local machine shops shave the outer of b series flywheels before, and haven't had a problem. but just the outer of the flywheel, thats where it is going to have the most effect. and also get your whole rotating assy. balanced.
