EJ Engines

the 2.5 is a bored and stroked 2.2, and the 2.2 is a bored 1.8. If the Jun crank fit into a 1.8 block, you'd have to do the math to figure displacement. It won't be 2.6L unless you bore it out too.

incidentally, the 1.8 block may not be strong enough after all that work.

-the SVX 3.3 H6 is a 2.2 +2!

I've read that:
-Jun makes a stroker kit for the 2.5L to 2.6L
-the 2.5L is a bored 2.2L
-the 2.2L is a bored 1.8L
-the 2.0L is a bored 1.8L

Correct me if I'm wrong. My memory sucks! But if this is all true it follows that a 1.8L and can be transformed into a 2.6L!! Am I missing something here? Sounds pretty crazy to me...

Huh? Please dumb it down for me.

The SVX motor has the same bore size and stroke as a 2.2....just 2 more cylinders. Kinda like a Chevy 4.3 V6 being a 350 with 2 cylinders lopped off....but more superior!

I don't know about Subarus being any more bore-able than another motor. You'd have to talk to a motor builder who knows where wall thickness danger begins with certain alloy steel cylinder sleeves.
