Default 84 TRW pistons.

How much stronger are they then the stock pistons 86-96?
Is it worth to swap them with my 91 stock pistons? I got 8 for free by a friend.
Can they handel a blower?

Thanks

I always thought that the '84 pistons were cast. Learn something new everyday.
Right?

Used pistons???

Waste of time compared to what you have to do to do it.

New pistons are only ~200 bucks.

:confused:

You should have the cylinders lightly honed. Then the pistons, and cylinders should be measured with a micrometer to check the clearances. I'm not sure if a blower motor has different specifications for piston-to-wall clearances, but I know the rings have certain gaps for blowers, and NOS. The pistons should also weigh about the same, or you will need to re-balance the crank. Good luck, and I hope this helps some.
