Default kind of a newbie turbo question

ok, so I've looked into buying a WRX because I want a turbo, and people have told me that it would be easier to buy a WRX with a turbo than to throw one onto my GC8. I looked into payments, and I'm not ready to saddle up for another 5 years with payments, considering this one is almost payed for.

anywho, my question is this,
I see a lot of people on this forum running turbos in their RS's but I do not know what kind of preparation to the motor would be necessary for a low boost 7, 8 or 9 psi setup would require. Is it mandatory to upgrade to forged pistons? What kind of management system would I need? If someone could post a typical setup for a reliable 7, 8 or 9 psi turbo that would be awesome. I don't want to lose my GC8 looks but want a turbo

thanks !
Jason

A "Low Boost" RS is about 3psi....9psi is considered high boost.

If you want reliability and don't want to worry about fixing stuff or breaking things then get a WRX.

If you want a low boost, similar performance to a WRX then go low boost setup (4-6psi) with stock internals, tranny, and piggyback engine management and it'll be moderately reliable as long as you keep high octane gas in there, keep you eye's peeled for problems and aren't a moron.

If you want higher boost than that you'll be on borrowed time with a stock block in my opinion. No sense in blowing an engine just to see how much boost it can take. If you're going to go for it, get pistons and rods. Consider o-ringing the block as well. For me, I'm just going to get a reallllly stout block, do it right and do it once (hopefully). As for engine management. I personally would not trust piggybacks anymore than I'd trust the stock block to handle it.

At least from what I've seen, big power in a RS-T = money and time. With the prices of used WRX's these days it's all a matter of what you want to do. For me, I get my enjoyment from spending time working on the project and the thrill of making power myself. Otherwise, I don't think it would be worth it.

Just keep in mind that once you get the boost bug you'll want more

I'd like to add to that... big power in a RS-T = waste of money and time

Reason? Get a STi block (like a V7 RA Spec C) if you want to make big power... Cost about the same in the long run....

Want the RS looks, but factory turbo performance and reliability? Do a WRX swap, any WRX will do. That'd be the best bet if you don't want to spend a ton of money..... or buy a 2nd car....... or have your heart sink at every odd noise you hear while you are driving around in your turbo'd RS whether it's from your car or not. ha ha ha.

wow thanks for all the replies. It almost sounds like buying a used WRX would be a better option for me, considering that this is my only car. I'm just really going to miss my RS's good looks.
I'll probably keep my RS until buying either a used WRX or brand new is more in grasps for me financially.
Thanks guys!
