SETA block and postings diff than regular ETA???

[Overlord475]

Was the block and pistons from a seta different than that of regular eta's?

Or were the only differences the heads and management systems?

Looking to do a 2.7i stroker starting with an "I" engine. Just wondering if I can buy any ETA block, pistons, and crank and call it good or if the SETA was special or different in those areas.

So basically wondering what i need if I'm starting from and "I" M20B25

Thanks

the pistons are different than regular etas. They have 'i' shaped pistons that have a bigger bore than the 'i' pistons.

to do the stroker you need an entire eta bottom end - crank, rods, pistons. Not really worth it if you're coming from a b25. Do a 2.8 and use seta, or i thiiiiink you can machine b25 pistons.
