Found a 2.2 ATI harmonic balancer and was wondering if it is the same as the 2.0 LSJ. ATI could not tell me. Anyone know for certain yes or no?Thanks.

 

pretty positive, NO..

 

Ask 06blackg85ss because Paul is using an ATI in his new build.

 

No, the lsj balancer uses a 6-rib belt. the 2.2 uses a 5-rib belt. you can use the lsj balancer on the 2.2, but not the other way around.

 

The ATI site states http://www.atiracing.com/links/pr/ecotec/index.htm

 

what exactly are the advantages?

 

how much lighter is it than the stock harmonic balancer and has there been any reports of problems with the ATI dampers?

 

the ati damper is not lighter. it is heavier with a damper. the lightweight crank pully's cause havoc with lsj timing chain/ lower crank gears; they wont last long. a damper pulley with a lightweight clutch/flywheel is a good idea. send 06blackg85ss a pm

 

kinda threw me off talking about lightweight crank pulleys going to clutch/flywheels.
so lightweight crank pulleys and alt pulleys are causeing probs with our timing chain/lower crank gears? i havnt seen anything on here about that yet.
Does this unit replace the crank pulley?

 

I had a light weight pulley, guess who's, on my DD and it crapped out after 400 miles. Yes I was really pushing the pedal hard and I shifted and went for it. The rest is history and most know the outcome of that.

I will not use an aftermarket, light weight pulley again, I will look at using this ATI for the DD.

 

their pulley was junk from the get go tho, much like the company. Im looking at getting MRZ's pulley.
