Default turboing the 2.2 (searched)

I'm just reseraching right now, but i've only been able to find info on turboing the 2.5RS....not the n/a 2.2 which is probably what I'll be buying. In the future, hopefully near future, i want to buy an impreza wagon for my winter/daily car and run low boost on it. I don't want to spend a lot, or go through the trouble of a swap. ( I know how "plug and play" swaps can be, I drive a GSR powered civic). So, i've decided that a budget setup (quality parts, with me doing the installs and fab work) with good tuning will be exactly what i'm looking for. So i'm just looking for some people with experience in this area. What are these engines like? what should i look out for? etc etc. Thanks in advance.

i will, but then that will be my weekend car. Right now it's all motor (built/milled head, stock bottom end appx 11.4:1, revs to 9.4k) When i build the bottom end it's going to be boosted, making 350+whp. So I'll definitely need a daily driver, and since i'm probably moving to a place where it snows i'll want awd. - enter impreza wagon.

Your search was nil because you are in the wrong forum. Try the Aftermarket Forced Induction forum, and you will get far better results...

Honestly I didnt read that supercharger post....but my opinion none the less:

engine swap. It may cost less in the long run. The internals on the 2.2 are not as good and the heads dont flow well, which may affect the turbo spool.

my 2 cents. Thanks.

Edit: Low boost with a small turbo might be cool though.

90-94 internals are just fine. Forged in fact, except for the pistons in the NA. If you add some sort of engine management, you can get 210 chp 160 whp on 7 psi. Proven. And thats with no EM. But get the EM, thats also proven, ouch.

I think any turbo kit for the RS should work with the 2.2, they're both EJ-series engines, identical outside. Might need to make some adjustments with a boost controller to keep the boost where you need it, but that's not really a problem. Remember, the key to safety and longevity is tuning. Definitely get engine management.

Pull timing and add fuel that is higher octane to prevent detonation. That is all! Piece of cake!

So you're saying with the use of engine management that you can turbo a ej22 up to round 7 psi without an engine rebuild?

Would it really be worth it though? It's going to be a pretty low output isn't it?

Yes! 5psi without an intercooler, 7psi with an intercooler. All you need is a fuel controller and an EGT gauge. Be sure to keep your EGT (Exhaust Gas Temperature) near where you car runs stock and you'll be fine. Be sure to use at least 91 octane (93 if you can get it). That's it!

You may want to try different search queries, I did a huge write up on EXACTLY HOW to turbo a 2.2 liter. I know there's tons of others as well. Search for Unique Motorsports or Subachad here or on Google and all your questions shall be answered.

If not, buy a kit from Ludespeed or F.A.T.

from my experience with hondas i've learned it's all about tuning. With good tuning, (never any preignition detonation) I'm sure that the motor will last. IF the motor is well tuned then it's only a matter of how much cylinder pressure/power it can handle before the cast piston's ringlands go. I was planning on just retarding the base ignition timing, getting bigger injectors, and an AFC, then tuning with a Wideband O2. Although not as precise this has been proven very reliable.
