Default Useable mix and match?

So I know everyone says stay away from the EJ22-TT.
Obvious reasons of things being laid out differently in the US cars. Understand this.
Am I correct in assuming it has: Closed deck, cast pistons, forged rods?
Couldnt you take this. and use it as a building block? ver 7 or 8 heads.
Different exhaust manifold (since its setup for dual Ts) etc?
Is there something Im missing?

Ahh , sorry bout that.
That was meant to be EJ20TT.

So back to original question. What is known about this engine?
Im really considering buying one to build up. IE not using the heads or turbos etc.

You don't know about it..


The EJ20 twin turbo should have the same block as the EJ20G. I know of at least one member that chose the TT heads over the regular DOHC WRX heads because they were available, and he has had good results.

I would think you could just swap exhaust manifolds, and bolt it in like an EJ20G.
