Question Modify a Normal 2.5 to better than STi?

So, I am considering an STi, I just can't get over that the base price for it is 18k over the base Impreza with the same (general) engine.

Do you think it would be possible to take an $18,000 Impreza, hand it to a professional and for another $18,000 have it outperform an STi?

I know there are other issues like retail value would suck compared to the STi, but i am still interested in opinions.

Thanks,
Heath

I'm not specialist but I would say yes... You just have to remember that the extra money for the STI is not only for engine. You get 6spd, DCCD, Brembos, recaros and lots of other things... I would prefere the STI, but that's me.

For all the money you spend on making your imprezza beat out a STI, you would have an STI.

Just buy an STI. It's a better all around platform to build off of.

They speak truth. But, if you were looking for a budget STi, get an older one, gc/gf and go from there.

I have an 03 WRX but, all the guts are 05 STI. It cost me $8000 to buy a wrecked STI and swap it over (probably would have been 10K if I'd had to pay someone to do it).

I think you should look at insurance costs before you decide. The STI is worth the extra money (more like 10K though) but, insurance even for married adults can be murder. I fly under the radar, no STI badging or large wings but, my car can do anything a regular STI can do.

Down the road, if I ever decide to sell it, I'll never get the money back out of the car I have in it. If anything, with the swap it's worth less than a stock one would be (unless I could find the right sucker to take it off my hands). I love the looks of the GC's but, they're not nearly as safe or as well constructed as the GD's are.

Why do you prefer to start with a 2.5i (no turbo)?

You can pick up an 08 WRX with very low mileage for around
$20k. Bolt on the 2009 WRX's Turbo, a downpipe and accesport tune & you'll make over 310 TQ at the wheels & 275 AWHP.

So the HP part is easy. That still leaves you the six speed tranny, DCCD, fender flares, BBK, suspension, wider rims, sticky tires, better wheel bearings, etc. etc. before it outperforms the STi.

I guess if you want a sedan version of the new STi, it might be your only way to go.

You joined in 2004 and post a silly question like this? Why in gods name would you want to take a Brand new 08 impreza and spend a additional 18 grand to have it hopefully beat a STI? Doesnt seem very cost efficient. Lets take a look

-18k impreza (not including tax title and lic)

- Engine build. Im assuming their dohc? Or SOHC on na impreza's. Either way expect to dish out about $5k. Bringing the car to 23K

-Turbo kit around another $3k. Car= $26k at this point

-Suspension any where from $300 to $3500. We will say just springs at this point. Car is now $26.3k.

- Brakes. Will if you want equal or better than brembo's you can do stoptech for $2k for the front $1.2k for the rear. Car is now $29.5k

-Transmission and Diffs. Fully built 5 speed with new clutch and diff around $7k. Car is now $36.5k

-Ill stop there


Of course there are going to be people to disagree with me. You can find cheaper parts, used parts etc etc. But the cost is not going to be that much lower. If you went with the above list take into consideration labor and misc parts i left off (exhaust etc). You could wait until the end of the year when they probably blow out STI's for 8k off retail again. Plus you get this fabulous thing with a new car called a warranty.

people always forget the engine management ..

even if you did the above you need some way to tune it ... and if you live in a state with emmissions its just not gonna fly

i would even dispute the same general engine ...
if you used that analogy, a 1989 legacy wagon 1.8 would be just as closely related as a 2.5i

a wrx with sti stuff is just a hotrodded wrx. It's never gonna be a sti until you waste so much money everyone knows what a dummy you were.

You will save money just buying an sti straight out the line. Also save a big hassle doing the swap and looking for the parts

you also need to sit down and figure out exactly what you want out of this project... cause otherwise you will end up spending so much that an STI will seem sooo sweet!

for instance my project I wanted to do one so I knew everything about my car, also I wanted a car faster and better handling than a WRX stg II so I got a bigger turbo, EWG, STI suspension, etc. and since it is going into a 2nd gen. legacy it will be an awesome sleeper everything I want!
Down side is I have not had a car for a month now, there is soooo much work that sometimes I wish I just had my old WRX back, and I am struggling to still find a donor.

There are pros and cons to everything-- the first thing you NEED to do is figure out what you want out of the end product here, cause it could easily be a lot higher than 36K
