Other than the numbers, those are the general specs for all new subaru
engines. (turbo engines have the individual coils on plug, the 2.5 is not
and the 2.5's have been going back and forth from DOHC to SOHC for quite a
while as well, SOHC since some early 99s slipped out with DOHC) WRX (US, and

the past years in Japan and whre ever else they sold the turbo cars have/have

had DOHC with coil on plug ignition.

Have you read about the variable valve system that subaru is running in
Japan? That is where the gains are at. The variable runner length is good
to, but it won't help a turbo engine. That technology is sort of behind the
game as many other manufactures have done it and some have moved on to
variable valve systems.

As for turboing the EZ30-

Almost 900 HP from H6 3.2 liter

There's that old saying "There's no replacement for displacement".

900HP from an EJ20, even stroked, is basically impossible. Increase
the displacement by %50 and look what happens.

Wow.

I'm guessing that is in a Legacy. Any chance of any pics? That is
one impressive car that's for sure. I think if I had 80Grand I'd
probably build my own car but that would be a good already built car.

Well you look at Indy car (CART) engines......they're 2.65 liter
engines, run insane boost and make around 800 hp.

I think that's 80 G's Australian so around 40 American

It's supposed to be an STi version so probably in an Imprezza rather than
Legacy

Don't know about pics, but you seen one Imprezza you seen 'em all

I agree, but when dealing with realistic rev limits and fuel
restrictions (octane), displacement is a very nice way to compliment
a larger turbo.

If my engine could rev much past 7000 without the valves floating,
that would be great, but neither can i realistically run on methanol
or some uber-octane fuel.

What RPM was that peak HP attained at? 12500? 20000?
