Naa... the Subie is much bigger. Anything more than 5lbs. of boost will grenade the Isuzu engine (without MAJOR mods) I've seen Subaru engines making 400hp. on pump fuel...different deal. The flat 4 was made to be boosted, the six was not...too much compression, among other things. You are right in your nostalgia take...the old mans' series two E-type is still a special car to drive, but a Miata will out drive it everywhere but the straights, and is a better car in every measurable way
