Zavier: Yeah, but thing is you can pay for all those items (timer, fuel pump, etc.) over time, and in the mean time, at least you have a car. I like the idea of being able to build it up over time, and make it more customized. I dunno about you, but I'll take a lot of pride in being able to all this work myself, and it also gives you something to always look forward to. You don't get bored of your car as fast.

Plus, look it it this way, you can achieve the same power of the WRX, with still keeping the 2.5i stock. All you do is slap on the Turbo, and do very little tuning if that (Which is what the WRX has). You'll basically only start having to add all the electronic/controls at around the same point that a WRX owner would have to do the same thing.

RewSupul: Thanks for the input.

I'm definitely lookin forward to finally gettin one of these cars. I can't wait.

 

Putting a turbo on your NA Subaru is not the smart, easy, reliable or cheap way to make a faster Subaru. But it can be more fun and more rewarding.

 

Very well put BAN SUVS.

I almost forgot to add:
One thing I like about putting on an aftermarket turbo on the 2.5 N/A, is the control over it. When I want to just drive around town, and have better gas mileage, I can turn the boost down.

I guess you could also do it with a WRX with some work, but I'm not sure what effect turning the boost down on a Low Compression engine would do in the instance of daily driving and gas mileage.

 

o i don't really plan on building my engine up for a turbo lol...i wanna do a fully built NA motor...but that might eventually change...

as it looks to build up for an NA requires all the parts for a turbo except instead of using low comp. pistons you use high comp...so i figure if i get tired of the NA build i can just change the pistons and some other ish and slap a turbo on then...

 

In my head though... wouldnt you want to just use your NA engine as is until it breaks down and just do an engine swap for the Sti engine? I am new to subarus and come from the Eclipse 4g63 engines and thats how we would do it for in the long run it would save alot of money and time rather then turboing a NA setup.

Am i wrong? *seeking advice ....* My route was just to save for an sti swap... am i really better off turboing or SOHC?

 

No, if you have the means, you are much better off doing a proper swap. It will be faster, more reliable, and probably more economical in the long run.

 

Not to change the topic, but while we're discussing the NA 2.5, does anyone have a diagram of this engine?
I was just curious how the SOHC works the Valves on this Boxer Engine.
I've looked around but have yet to find a reasonable diagram of this. Plenty of V's and Inlines, but no boxer diagram. Thanks.

 

The boxer configuration doesn't affect the way the valvetrain works. The SOHC camshafts just have twice as many lobes as DOHC camshafts to operate both sets of valves is all. Otherwise, jsut look at a SOHC inline 4 and pretend it's an inline2... then you will see pretty much exactly how it works.

 

I like the idea of an engine swap after the NA wears out or when I get the car paid off. How much would it cost for the engine itself and also about how much for the total cost of the swap (including engine, labor, any additional parts, etc...) What is a ballpark total figure if switching to a WRX engine (not STi)?

 

Ballpark is $7-10k, depending on age/type/mileage of the engine or drivetrain you choose and what services you add in during the swap.

 

7-10K$,!!?!!? Well, there goes that idea then. That's almost half the price of a new car. May as well just get my use out of this one, get it paid off, and look at a WRX next time around (if I hadn't been upside down in equity, I would have gotten the WRX)...as long as they are not still using anything similar to the 08 body style in the furture when I go to buy again (puke...wharfff...splat...someone hold my hair back). I don't want to own a mazda/focus half breed...lol. Maybe they'll have an AWD mustang by then???

 

Pull your heads off and slap them on an STi shortblock.

Higher cam lift+2.5 power=sexy turbo motor... I've seen guys make a good 260 outta it.. (use stock intake manifold/wiring w/ piggy back)


Shouldn't cost half as much as doing a full swap...

 

Am i able to turbo a NA 97 legacy outback 2.5l EJ25 DOHC? Or would my best opption to get more hp just be to bore it?

 

Would you guys happen to know how much it would cost to just turbo 98 impreza 2.2L engine. or any direct bolt on turbos off other subarus.
