But yeah, any info on the ver6 ej207 would be cool. I just wanna know more about the internals. I think they are forged , but not 100% on that, so it would.be sweet to get more information!
I've owned two V5 STi Type RA 555 WRC Limited and have rebuilt the engines.

V5/V6 is the first Phase 2 EJ207, it uses a single coil pack. It's designed to run to 8000rpm without issue. It uses under bucket shims on the camshaft.

V5/V6 STi engine is the same internally. It uses Forged pistons.

Rods are the limiting factor on safe power, the V8 rods are stronger.

Crank has the same thrust location as the later engines on the V5/V6, it is not nitrided or crossdrilled.

Block is an open deck design.

The STi V5/V6 engine is the same spec as used in the P1.
