Rods are identical between n/a and turbo. The only B6 that got bigger rods was the 88/89 323 GTX, the 88/89 GT didn't even get them. And the beefy rods are superseded by the regular rods via Mazda (if they needed to be replaced) There's been no proof they are stronger, just bigger. There should be some affordable aftermarket rods out there now, for a long time there were no good/affordable options
(Quick look on eBay shows chinese made h-beam rods as cheap as $250, Carrillo rods are still $1200+)
This is where sharing parts in common with the Miata is nice, the internals are the same and you have options for aftermarket stuff.
