Throw and h22 in it way beter then that Mazda v6 make more power i think and it a lot easier then swapping in a Mazda v6 since lots of custom work is needed and Ur not gaining to much i think the Mazda engine make 160 and the jdm makes 200 while the euro h22 has 220 and a lot cheaper route . if u feel like a v6 still go with the j32 Acura cl/tl s motor 260 hp and grab a six speed cl tranny and have fun.
