Default Perfect Sti engine?

Just wondering, if you were to build a perfect Sti engine using parts from any previous/current Sti motor, which parts would you use? Like a USDM 2.5 block with a V8 head or what? Please enlighten me!

i would get a old version 2 block "fully closed deck" with the version 8 sti RA heads.
you would have to get new pistons and rods but you would be able to boost the hell out of it and rev to 8500. perfect.

V8 spec C heads, crawford EJ22G block (closed deck), valve timing controller (dont know if they have them for subies yet, i know there is some for toyotas), Utec, titanium valves and retainers, V6 RA drivetrain, APS turbo or something in that catagory, ARC top mount, Water injection, and all the other goodies.

or, instead of the ARC, flip the intake maniflod around and go for a psuedo (sp?) WRC setup. intercooler in the upper grill and maybe even V mount like they do in the WRC cars... that would be sweet...

Hey! Crawford is not STI, so thats cheating. Aswell out of most peoples budget.

My vote is the entire JDM V6 STI-RA drivetrain. Then swap in the EJ257, and a larger turbo.

Stock block there are still some debate between EJ22, EJ20G, or EJ257. Heads on the newer version definitely flows better, I'm partial to AVCS but given the wiring restriction might be better to do without it. So V7 heads, whatever block you like between the 3, and maybe pistons to make the compression ratio right (like for the EJ22 and EJ257).

You left out one of the best blocks up for debate; the ej207. And AVCS is not that hard to wire in.

EJ20G stroked with Ver 7 ra heads and screw the AVCS if your gonna spend that money you might as well put cams, a turbo and some good engine management in there.

The ver 7 block sounds good but what internals. The general concensus is that V8 heads are v7 spec c heads so thats a good thing. Have fun, I know I did now I am going back to my think tank its tax return time and I have to go shopping!!!

Just get a Ver7/8 drivetrain and swap it in. I have one in a 98RS with a pe1820 and txs tmic and this thing kicks your as! enough for me not to need anything else. My 2cents.
