Subaru Stars STi engine swap in a 2.5i

I don't know if this is a rediculous question, but I thought I would put it out there. I was looking on a tuning website the other day, and they had fully built STi motors for sale. They ranged in price and hp output, but they had a fully assembled STi block for $3k. Just wondering if the swap is possible? Any help would be appreciated.

Possible? Yes.

Worth it on your low milage 2006 Impreza? I wouldn't say so.

Trade up, get the power and the warranty without the problems.

Please, by all means, correct me if i am wrong, but wouldnt swapping the engine make it so you have the insurance of a 2.5i and not the STI? <as opposed to trading up where you have an sti and the insurance ramifications?

I am also thinking about this.

You won't pay as much insurance but you just pissed away a new engine.... If you are going swap buy an older 2.5 one with some miles if insurance is that big of a deal.

You'll have to swap transmissions, axles, drive shaft, and rear diffs. That gets really expensive really fast.

I priced the whole thing out (JDM spec of course) and it was almost into $10,000 for just the parts.

you could do just a plain WRX swap for half the price and make some pretty good power.

Um no U dont have to swap any of the drive train. U dont even have to swap over the whole harness, just do a good size splice ( but its easyer to swap over the whole harness )

$3k for a long block is a good price if it comes with all pumps and harnesses. You will need a turbo crossmember .....unless the NA 05s and up are comming with them now. Also needed unless U get them w/ the motor TMIC-FMIC, turbo,DP-UP-turbo headder, Turbo ECU for that motor or stand alone

the swap can be done easyily for $4k if you are doin the work and not looking to upgrade anything B4 U turn the key. Maybe $3500 if you rilly have connections. I would sugest a STi radiator or KOYO-Fluidine ect. There are many other things needed to be done if you swap over from a Na to a turbo motor. read search and then search some more...........knowledge is power Yo!

You either have to swap the transmission or seriously modify the stock RS one... they have a completely different clutch setup on N/A Subarus (pull vs. push clutch), and the cost of having one converted would probably equal the price of a turbo transmission.

why buy a new car and swap the engine?

If you needed more power and didn't have lots of money you should have bought the TR. What would it have cost? 50$ more a month?

Geez, the stupidity never ends.

another thread that doesn't belong here.

barlokat's thread belonged in aftermarket forced induction, just like the supercharger thread.

this one belongs in conversions.

and about insurance- sure you'd get insurance of a slower vehicle but it would also be lying to your insurance company to get a lower rate which is also known to some people as insurance fraud.

I dunno if it would be THAT close...my 2.5i payments are $425/month...and a WRX would be almost $700/month, and that is just financing, not to mention insurance.

You would have to modify nothing on the transmission. You would have to put the rs flywheel on the 257 block and everything fits. That's it. Where did you get this information from?

Other than that though, Ya this is the wrong place for this thread.

Well you learn something new every day. I was wrong... sorry!

I had made that conclusion based on attempts to find flywheels for my RS a while ago. Looks like I was fed some bad info.

You can't compare.

He is in the USA. Subarus are cheaper there... WAY cheaper.

Well, thank you for those of you who actually provided some decent advice, sorry if the post was in the wrong spot though, I'm new to this whole forum deal. Anyway, to answer a couple questions... I couldn't afford the insurance on a turbo vehicle... period. And to whoever said that its lying to your insurance company, technically, its not lying, do you have to go to them when you put a CAI, or ECU, or catback? I don't think so!! The registration says 2.5i, and as far as I'm concerned, thats all they need to know. Thanks for the help fellas!!
