"It's blue must be fast"

Default 2.5i turbo dont look if you dont have answers please

2007 2.5i 16,500 miles

I have posted a number of times about different options etc. I have looked into turbo charging and haven't gotten any straight and knowledgeable answers. The one answer i have gotten over and over again is. "sell it and get a wrx" I DON'T WANT TO.

I have looked into getting a short block and building it up, but the responses i have gotten from that weren't good either. Still i got the, "sell it and get a wrx." Thats not what I'm looking for. I know it's not easy, I know it's not cheap or worth it. But god damnit i want it.

This is my proposition, can somebody tell me if its safe, if its not what i'm gonna need to do to get it safe. Im not looking for monster gains. I would be happy with 50 horsepower.

-I would like to install a stock WRX turbo system on my engine. I am not looking to boost any higher than 5 psi. I am aware that i have 10:1 and that i have SOHC. I am ready to put header back exhaust, FMIC or TMIC on the car. And if i need to put larger injectors on the engine so be it.

What i want to know is your input. Please knowledgeable descriptions and parts descriptions.

Thank you in advance for your help. It is very much appreciated

Title of thread isn't serious

If thats your cup of tea then go for it. You WILL get bored of that measly 5psi and want more.

From a wrx your going to need:
Headers
Up-Pipe
Turbo
Turbo Inlet
Intake
Full Turbo Back Exhaust
Top Mount Intercooler
Injectors

Not Sure on these items:
Intake Manifold
Throttle Body.

Plus youll need some sort of boost controller

And then you will without a doubt need a tune.

You can get a conservative tune that should be pretty safe but your putting added stress on your engine and drivetrain so reliability could be an issue if this is your DD.



I still don't understand your WANT for something that you know is pointless and much more easily obtainable with the purchase of a wrx.

that could be a huge issue

I wouldnt run anything more than 5psi, and wouldnt rip the transmission apart while doing so.

i cant see it being THAT difficult as far as bolting on parts, its the tune im worried about and things of that nature.

your car is actually DOHC, I'm like 95% sure. Also, have you thought about getting a supercharger and fabricating it to fit on your car? It seems like the em part of the project would be the same as a turbo, the only difference is that the difficulty comes from fabrication instead of installation. It might also be cheaper, if you're not counting the time it takes to make it work. People have done it (reddevil and others) so it is doable, plus it is more unique and a more linear power delivery. You would also get to keep the same aftermarket exhaust you may or may not already have. Something to ponder.

+1 you will get tons of help there. this is exactly the type of stuff the people in that forum do. Also, i dont know if a boost controller solves the ECU problem or not, but i have been told that the OEM ECU cannot account for MAP's above atmosphere so you may need a ECU solution or another ECU (WRX ECU?) or your fueling will be way off. Im pretty sure that you will need larger injectors/fuel pump. It looks like the injectors on the 2.5i are running pretty close to max on the stock setup. But if you do end up doing it, theres no doubt you will have fun. I had a turbo once... ONCE. rebuilt it once after blowing the stock setup. It was fun, but i was never satisfied with the power and wanted more. its like a bad drug. ended up costing me another motor due to oiling issues. (damn 1st gen eclipses)

If its a USDM 2007 2.5i, im 100% sure its SOHC.

I have the answers but in all honesty I don't really think you want to hear them. You are thinking about boosting a leased car? Are you kidding me? And then you say when the lease is up you want to do an STi swap? That's going mean if you turbo it now, you will duplicate and redo 90% of what you have done at the end of the lease.

You can always get out of a lease. It's really quite easy. You do what you have asked us not to tell you to do... You go to the dealership that leased it to you in the first place and give it back to them and walk out with one of the new factory turbocharged cars. Simple as that.

And before you start calling me a hater look into me a bit. I build NA cars. I do swaps on cars. I slap turbo kits onto NA cars. I play in all the fields. I don't discourage good ideas. But I do discourage utter stupidity and I don't see anything that seems smart about modding a leased automobile that much. My '08 WRX is leased. Until that's up, all it's getting is an SPT exhaust, a Cobb AP and some nice rubber. I might grab a few cheap suspension goodies, but you can be sure I am not putting a bigger than stock turbo on there, not even an STi takeoff, which isn't even very big. It just makes no sense on a car that I do NOT own. If I was financing it it would be different, but it's a lease. Modding a leased car is the realm of idiots...

My advice? Run it with mild bolts ons for now. If you still love it when the lease is up, boost it then or do a swap on it. Until then, focus on the driver and the handling.

Sorry dude. I agree 1000000% with this here.
If you want to turbo your car, then by all means, have at it. But turbo'ing a lease vehicle on a lease you can't get out of... THEN swapping an STI motor at the end of the lease...
At least wait til your lease is up, seriously.
And don't forget you're going to need a new crossmember, probably a clutch, and depending on what you're looking to accomplish/how you'll be driving, maybe a new tranny. Upgrade of brakes etc. etc. etc.

Don't come straight out and say you're going to do it 100%, until you've 100% researched everything.
And please, do NOT tell me I'm flaming.
I gave you advice ^^ in terms of clutch/tranny/crossmember/brakes etc.,
I'm simply stating an opinion along with it.

Listen to the man, you gotta be able to stop faster once you can go faster. Beefing up all the driveline **** will become necessary too.

At least everyone is being honest with you. I know this is not what you wanted to hear, but there are lots of good deals on 08 wrx's out there.

Kudos to you. We are so used to someone getting all butthurt when we are honest. Your response is mature and shows that you listen and think.

There's lots you can do to your car in the meantime. Work on the suspension and brakes. And get some track time. Learning to drive that car to it's full potential will make a huge difference in how you feel about it. I owned my RS for 4 years before I really did anything to it to make more power. In the meantime I got it all sorted for handling and had so much fun on mountain roads all across the west.

I am in the same situation. As a first time 'leaser' I got suckered into the 'awesome/great deal' 48-month lease at $179/mo. ($222/mo. after the wing and taxes were capped in), and because I am on my own auto insurance plan, it would have been way too much money to get a WRX or STi and pay such an enormous premium. So with that said, you'll have to trust me and understand where I am coming from on this one.

I have been on the boards since early 2006, reading,reading and more reading about doing a swap. I have been flamed for posting similar questions about swapping, turbo-ing and everything in-between. What I have come to realize however - and you probably will too - the more you read about what your asking, you'll find that it isn't economical nor worth the headaches and problems down the road.

I am not the type to rain one's parade, and by no means am I telling you not do it, but in the end you'll be much better off saving your money and buying a WRX or STi. Your '07 is still unmolested and doing a swap or even turbo-ing it would require quite a bit of pulling apart. The car will never be the same once you convert it. The idea of turbo-ing it is a little less invasive, but despite this, the question isn't IF you will run into problems down the road, but WHEN. Our motors as you seem to already understand - which is good - are not designed to handle boost, end of story.

So long story short, and I'm sure its not what you were looking for, but its coming genuinely from another enthusiast (that has the same passion for power, but still stuck in the N/A world), invest your money in suspension bits, aesthetic bits and maybe a sound system, and wait until you can afford to get into a WRX or STi.

Best of luck either way.

what I don't understand is...if you plan to KEEP the car in the first place, why did you guys even lease?

Lease is a long-term rental agreement. It's like you're spending 1 1/2 new cars to get 1 used one.

Not necessarily true. Guess what I pay on my WRX? How about $150/month. SOA has been giving silly lease deals the last two years. If I buy my WRX after 24 months when the lease it up, it will have saved me more than $3000 over if I bought it now and financed it for 60 months. Leasing can be approached from a number of ways if you know what you are doing.

im glad to see you say this. youve actually listened to our recommendations!

haha but like others have said, put in some track time, get some suspension mods.

my 20mm rear sway bar was the best thing that ever happened to me i enjoy going fast around corners than fast in a straight line any time

This is a much better idea.
Or even if you were going to go the turbo route, I'm not trying to discourage. Just know, you'll need driveline components/clutch/tranny/brakes etc. etc.
but DEFINITELY, no matter what you choose, wait til the lease is up.
