will the 86-88 flywheels work on 89-91 na's ? racing beat has them as two diff parts numbers ? are they compatibale , if not why ? thanx

 

Stock flywheels?&nbsp No.
Aftermarket flywheels that require (auto trans) counterweights?&nbsp Yes.

The stock flywheels have the counterweights integrated with it.&nbsp So differing weight rotors (1986-1988 Zenki versus 1989-1991 Kouki) NEED different stock flywheels.&nbsp Aftermarket flywheels have no integrated counterweight - they use the appropriate year (Zenki or Kouki) auto trans counterweight to give it the right balance.

so Ted what your telling me is that the racing beat 12# aluminum flywheel and counterweight that is an someones 86 na will fit on my 90 na ? i hope thats what your telling me . lol ... Ted Koseki strikes once again in a clutch situation .

 

Yes and no.&nbsp You can use the 13@ aluminum flywheel, but you'll need a new counterweight for your 86NA.

i have the 90 na and i just purchased the racing beat flywheel that was on the 86na . so what i have to do is purchase the racingbeat countereight that they have for the 89-91 models b/c the counterweight i have is for the 86-88 models . so basicaly the actuall flywheels are the same for 86-91 but the counterweights from the 86-88 and 89-91 models differ . so basically i need the 89-91 counterweight and its all good ? i hope i got it right this time . i really appreciate your help Ted . thanx a lot

 

Yep, that's exactly it.&nbsp Man, I can't type for crap today!&nbsp I dunno how I got "13@" when it was supposed to be "12#"!

once again thanx .. i dont know what some of us would do without guys like you .

 

The Aluminum or Lighten Steel aftermarket flywheels are different between NA's and T2's.

AND, the counterweight in both cases comes from Automatic versions of your car. So, you could save a few bucks by going to a wrecking yard and pull from a same Series Auto Rex.

A T2 counterweight will do far more damage to your wallet. No T2 Auto Rex's were imported to the US. But, might get lucky from a Jspec engine dealer.

 

so all i have to do is get a counterweight from a 1990 automatic 90 ..damn that will save me some money .. thanx a lot . oh yeah i do have an na

 

Actually, check e-bay too. I got one for $15 and another $15 for shipping (heavy buggers). I love my friends at Mazdatrix and Racing Beat. But $30 vs. $145, my wallet talks louder with that difference.
