Hmmm... let me see... easy and cheap power or expensive power with little gain.

Gee... I wonder which one to choose.

Reliability is not an issue if you do it safely and take care of it!

just boost the stock motor. youll get sufficent gains for daily driving. the only hassle would be reliability.

I bought a $200 downpipe and picked up 70whp. What's your point?

Bingo... for less than 2000 you could get a very nice home-made turbo kit that would seriously rock your socks, and be less obnoxious than tearing into your motor.

go turbo with k-pro, get it tuned by a good shop, make decent power. and have plenty of room to upgrade in the future. realibility is in the hands of the tuner.

i'd go for na since i go to the track alot. need all the power within the rpm bandwidth. (also, because my engine is the jdm k20a dc5) and the power is already good enough. anything less than the jdm engine, i'd turbo it, best bang for the buck in terms of $$$ to horsepower ratio.

Subaru EJ257. Dyno'd at 238 to the wheels and after a downpipe and a quick tune, it makes 304hp at the wheels.

That's pretty dramatic, but the K20 should react well to boost... it's got a fairly potent set of tuning parameters.

a NA motor thats relatively stock will and should always outlast a boosted motor regardless of the internals.

true, but an n/a motor that is relatively stock is also gunna be relatively slow. and if you want any decent power at all, then you wont have a relatively stock NA motor.

if you build a motor right, tune it right, and actually take care of it, then there is no reason why it shouldn't last just as long, if not longer, than an n/a motor.

NA motors turn the same compression every revolution. regardless of how hard your getting on it.
and turbo motors CAN be drivin out of boost, which would mean less strain on the engine.

your post would be contradicting itself. a low compression motor driven out of boost actually makes less power than a completely stock motor.

without setting guidelines, we cant exactily debate on the subject itself. there has been nothing said about how much power the NA or FI build was making.

most people get simple bolt-ons and maybe a reflash, but generally leave the internals untouched as it starts to get expensive if you want to completely redo the head with a pnp, cams, valves, retainers, a tune, a tuning device like KPRO.

if you choose not to void your warranty, your powertrain is guaranteed for 7 years 75000 miles if its an 06. how many boosted engines have lasted 75k miles? i know of more that have had needed major work compared to those that have lasted 75k miles.

i said a boosted motor CAN be run out of boost.

and sure you here about more boosted motors blowing up because most people are cheap and dont treat there cars right. most people think they can just bolt a turbo kit on and go. which is not even the begining of having a properly running turbo car.
if you want power and reliability then its not going to be cheap.

and most people do just get simple bolt ons and possibly a reflash but those people also arn't goin to have much power.

regardless of if you go n/a or f/i, if you have it built right, the motor tuned right and take care of the motor, then it should last as long as any other motor.
