1970 240z with STI motor
 

Now i am a huge fan of subaru and that boxer engine, use a newer STI motor and trans in something small and pre-smog would be sick...:pot_stir:

This would work fine/great and if you love the Boxer sound (I do too) it's a good way to go unless you want to get an actual Porsche engine. Still, the I6 or V8 is kind of the way to go for the old Zs. They have enough room.

Everything thing is better with a LSx, I do not like the sound of boxer motors, and you have to REV the nuts out of it to make any power.

I was kinda curious. Here's a great post on the STi vs. Evo, motor, AWD, and chassis comparisons and what the pros/cons of the Boxer are.
