compression...

so you get what im trying to say.... its not the same... hell the new wrx uses the same platform as the legacy... but that doesnt mean a impreza 2.5i is a SPEC-B.

i get what you are saying, but what i'm saying is that the block is capable of the horse power as well. its just a matter of buying the same stuff thats on the Spec C type RA and you can have the same horse power. so its not like its anything new really.

The base block is not the same besides being 2 liters. Buying the same stuff that is on the Spec C would involve buying the complete engine.

I suggest you go research before you post back in this thread.

I don't think the EJ205 (USDM) and EJ207 (JDM) shortblocks share any parts. So I guess if you want to replace the crank, rods, pistons, etc. then yeah the US 2.0 is as good as the JDM one.

That doesn't even take into account the heads with much larger ports, more aggressive cams, etc. from the full longblock. EJ205 is not in the same league as the EJ207 in my opinion.

To the original poster nice numbers. Over 300whp on a EJ205 on pump gas is very impressive.

How do you like it? Sorry to go OT, but I am looking at doing new gears but everyone says the RA's are not really a step up from the 05 gears.

my RA 6mt is soooo much nicer than the usdm 04 6mt that i had

its perfect for racin and keepin it in the power band - but its much like having a fung-fu fight in the drivers seat at WOT!

you can fit the same parts on either block. point in case. a wrx that was in power subaru in scottsdale. it was a hack job, but the block was from a Spec C but it had USDM heads, turbo, intake and Throttle. the only give away was the stamp on the block. the car ran like **** due to not having the right compression and all that from the swapped parts. but it will fit.
