Is the base model Protege short block the same?

[Mckinley]

Ive got a 2003 mazdaspeed with a blown motor.. is the protege block the same as the mazdaspeed fs 2.0?

yep. make sure to buy one from a 2001-2003 though otherwise the crank isnt forged and i think the head is a little different. if i am not mistaken.

but the mazadaspeeds crank cradle (the very bottom of the block) seems to have thicker walls and has oil feed lines for the turbo. the NA has thinner walls it appears and has no oil feed coming off the crank cradle.. anyone think i should just tap into the the NA 2.0s oil pain?

thanks for the replys.

Long block assembly is identical, swap the windage tray/crank cradle to the new motor, pay attention to where RTV is applied and o-ring for oil pump pickup. swap all coolant/oil line fittings to new motor, also oil cooler and threaded tube for oil filter.
