Do a search. also, try the forced induction section. Plenty of RS-T's with phaseII motors running around.

if i recall correctly, the bottom end of the phase II blocks can't handle more than 9-10 lbs of boost for long periods of time, but even those low numbers can really make the phase II come alive. i just hope you don't have the crappy 4EAT like me, cause i've been hearing that those don't like any kind of boost.

that might all be heresay though, cause i have yet to try something like this on my own car. like rougeben83 said, try poking around the F/I forums. anything that works for the Phase II 2.5 RS should work for your car with little difficulty.

Actually, the subaru 4eat is surprisingly stout and can usually hold more power than the 5mt. Torque converters are very efficient at dissipating shock and stress. Most stick to 6 PSI +/- to be on the safe side. 6 PSI on your ~10:1 compression engine will give right around 230hp (180-190whp) which is should be a HUGE upgrade in power. Before you consider turbo'ing your motor, be certain that your head gasket is still ok. You're car is of the age where a blown HG would't be surprising- my 00 leg blew it's HG around 125k miles. There are several ways of checking for this, all easily found with a quick search in the N/A forum.

Basically, it is possible to add a turbo. Expect to spend in the neighborhood of $1500-3000 for a used kit and plan on a "backup motor fund" in case things go wrong, which isn't uncommon. I'd say you should consider a WRX motor swap, but as I'm finding out, it's not an easy enveavor in a BE.

6psi is roughly more around 250-260hp, but that's by going by the numbers the AVO kit produces. 230hp is more like if you run a poorly tuned EM, or the cheapo RRFR/knock sensor setup; it will work, but not very well.

I think people underestimate how hard engine swaps are for any subaru; the suggestion gets thrown around on forums quite often because...well typing it is easier than actually doing it . Anyway, I think it will be worth it once you finish it (either way, as I'm going the kit route), but you just have to know what you're getting into, be prepared for problems, and not get frustrated to the point of quitting all together in the process.

Considering the CR, if you can safely run that PSI, you should be able to make some good power. And he's not talking whp.

Also, per JoeT, who has probably done more with boosting the NA in a Legacy than anyone here.

http://spda-online.ca/modules/newbb/...forumpost20511

A high compression ratio may be bad for adding tons of boost, but while it's there it does have a sort of multiplier effect to the boost that you are already shoving into the engine. It's just a matter of whether you can stay away from the Boost Addiction

JoeT and the Zen series is great material to read for anyone with the same questions I have about turbo'ing the NA EJ25 SOHC engines.
