Engine performance upgrades

the MAGNUM motor was JDM use only with a few exported to AUS,New Zealand,etc.It was the 2 liter block and head with domed pistons,8.5 to 1 comp ratio had a small turbo on some of them.145 hp I think was the rating,but everything I read said that was understated.Ive heard all kinds of tales about forged internals like crank and rods,but no one really seems to know.If there is a for real MAGNUM motor in ATlanta or whereever u found it,U should be all over it cause there are nuts like me would give there right cuhone for a set of those domed pistons.They were used in the truck,Capella and maybe one other application.Luck.BJ

have you tried mazdaspeed.com, they used to have a whole bunch of stuff for the 2.2 an 2.0s,
