Was cruising the net and found this: FireSport Classifieds: 08 mazda 3 MPS block and head $1000 $1,000
might be useful for someone looking at doing a big engine build while keeping their car on the road. I'd personally buy it and fill it with forgies and drop it in, problem is I got no moulah to do such thin atm
plz note that it's not mine and I do not have any connection with the seller.
