yes they will, but they wont work

89 pistons have a slight dome, what is it 4 ccs or something? but its enough to hit the valves on a DE

90 pistons work

ah, you really, really need ot look at them close, because you mihgt have earlier or later pistons

but 89's have a slight dome adn 90s have a slight dish. you want the dish, so check that out, adn post a pic if youre unsure

What about pistons for s14 ka to s13 ka? I am rebuilding my motor and found pistons for an s14 ka and was told by the distributor that these pistons would not work on an s13. I think this guy is wrong. HELP!
