How much does the OEM B18a1 flywheel weigh? or out of the S1 tranny?

 

ABOUT 19 LBS

 

I heard 18. and a type r is about 15.5

 

i thought it was heavier or atleast was hoping it was ...ohwell im getting an 8-12 pound not sure yet. im thinking 12 since its more daily driver and im not going to be on the road course everyday or anything. I Just was my car to spin up really fast. Its going to be an 75-8k LS non v-tec...thanks guys take it easy

 

stock flywheel should weigh in an 18lbs.

ITR is 14 or 14.5 lbs.

If you want to go as light at 8lbs, do yourself a favor and spend the extra $$ for a chromoly one. It is strong, lighweight, and they don't get resurfaced.

If you're not going to put much race time in the car, then there isn't a point to it really. That is the purpose of the lightweight flywheel, because on a raod course// auto X you are constantly going up through the revs. A lighter flywheel enables you to down shift heel-toe style and be in the right rpm range faster than the heavy flywheels.

Anyways...good luck with it.

 

it 18.2 lbs. Dont waste 400 dollars on a new flywheel. Go and pull your flywheel and take it to the machineshop. have it lightened and resurfaced. $80 for an 9lbs fly? not bad at all.

lightening the stock flywheel is not recommended it screws with driveability. just get a aftermarket its better

 

and u have the chance of the shop messing up and the flywheel exploding on u

I was fortunate enough that my OE flywheel didn't shatter on me after having it lightened to 11lbs.

ive been driving HARD with a 12 pound ITR flywheel for like 5k miles . .. shatter ??

 

Jason...

I'm not trying to scare people away. And you only took 2 lbs off the ITR flywheel versus mine was lighter by 7 lbs. Certainly a big difference.

I had ran my light flywheel for approx. 22k miles, the last few hundred of those miles were turbo'd.

At any rate, If I were doing severe weight reduction in the flywheel area again, I would get an aftermarket chromoly one.
