Default 2.5 swap vs STI

I have an 03 wrx, 40,000 miles- Does it make for sense to drop a 2.5 kit or to buy a 2006 sti?
Thanks,.
Ryan

This has been covered many times...all anyone here is going to tell u is do what u want...A lot of people love the sti and don't really do motor swaps....if you feel like being a little bit different then get the swap...if you feel like having a whole package all in one but just a STOCK sti while making payments...then....

It also depends on what you want to do with the car...

I do not have any extra money so all of this is academic to me, but I thought about the same with my 04 WRX with 36K miles.

My car has a rough trade in of $15.5K. An STi will run me $30K plus taxes. So we are talking a little in excess of $16K to trade up. I figure for $10K I could do a 2.5 swap, stronger gears, bigger turbo, and a few suspension upgrades. I would not have a warranty, 6speed, and smell of a new STi but I feel I would be rather pleased with my car at that point for less cash. Plus, the STi would not be a wagon

just buy a used sti.

a used sti can make a ton of power reliably. Your hybrid WRX will have high compression, a crap gearbox, open front diff, and ish for brakes.

While I know people do it all the time, I would pass on a used WRX, STi, EVO, etc. You never know how bad it was abused.

I am in process of doing a 2.5l hybrid and RA gearset changeout, water/meth injection, etc. right now and I can tell you, by the time you're done (if done right) you're going to spend just as much as if you traded in your wrx and paid the difference for the new STI.
I currently am at over 12k in parts alone. Plus my car has been at the shop, in various stages of assembly for over a month. Plus, a month's cost for a rental car, etc...
Will it be worth it in the end...HELL Yea! Will it be any cheaper? no way.

to each his own, i wouldn't buy any of those from a dealership but i bought mine off a single owner 42yr old woman who drove it to pittsburgh and back daily since she bought it brand new

if i were you, i'd get an sti. its not even about hp and quarter mile times. the entire car is designed so superior to a wrx

I think a 2.5 swap and RA gearset can be done for less than 12k in parts, do I want to ask where this is being done? The etc. must be significant. If it was at the shop I was visiting recently, I wouldn't be surprised. I was talking to one of the mechanics, and he was bragging about how a recent customer spent only 5k to make his car as fast as an STi..........

oh jesus a 2.5 sb swap would cost 3k at most, and an ra gearset 1-3 is like $1200

Assuming you can do all the work yourself it would cost < 5k

12k would get you a complete JDM v7 motor with harness and 6spd tranny with sti rearend lol


And a comparision I'm running about the same as an sti. slightly slower by slightly i mean at 100mph an STi is a carlength ahead of me.... i have less than 2500 into my 02 wrx - no EM only what I did myself

True, but there are some really nice ones out there that aren't abused and are hardly driven. For instance, my dad has a 2004 STi which barely has 11,000 miles on it. It has pretty much only been driven on nice weekends and he is thinking of selling it for the 2007. You just have to keep your eyes open and be patient.

well thats a tough one. I would probably just swap a 2.5 in. You've owned your car. You know how its been treated. Buying a used STi can be tricky. While there are some good ones out there, they are equaled with crappy ones.

if you buy an sti you know is unmodded, then you can be pretty sure that it's ok. The only way to screw up a stock sti is to misshift and send the motor to 9k and blow it to high hell.

For the most part, if the sti is abused enough to worry about, it's already broken.

It's not like the sti tranny has ever taken a dump on someone.

yes, but I didn't say just a hybrid swap....I'm talking about a new shortblock, forged internals, machined heads, new cams, valves, valvetrain, fuel rails, injectors, headers, ported & polished turbo, engine & tranny mounts, oil pan, tgv delete's, Aquamist water/methanol injection, new clutch & flywheel, RA gearset with syncro's and bearings and so on...
Trust me, I was keeping a spreadsheet untill I hit over $12k in parts..then I stopped counting I couldn't take it anymore.

40k for an '03 is nothing. I'd mod it 'til the engine blows, then do a swap.

Holy crap, KTR really is doing the same job twice in a row with you and me, though I already had RAs and meth.

I'm actually going through this same decision right now. It would be near impossible to get the same all-around performance out of my 02 for the 14-5k it would cost me to upgrade to an 04 STi.

Really the only thing keeping me from doing it is not wanting to have a car payment again. Used car interest rates are stupid high right now. 7% FTL

I have been going through this decision since i put 40k miles on my 04...the difference is i love my 04...i love the color, front end, wrx wing, etc....I think that it all depends on what your situation is...See, i have the suspension down, brakes are coming, and i love my interior (just need a bucket seat to be more comfortable! )


If it really comes down to it then i would love to just go motor swap since my car is almost about paid off...and yes i had TONS of help from MY PARENTS and i am not afraid to admit it with all the old folks on this forum that feel everyone should struggle as bad as they did to have a nice car . I would rather have a a motor swapped out with new tranny instead of making more payments on a new sti. I think the performance would be a lot better...The only thing is that i would need to get rid of all the creeks and rattles! With the few dollars i save with the motor swap i am just going to go ahead and grab myself a nice big juicy turbo! ...or something along the lines of a 20g!

oh yea.....04 wrx ftw! i love modding cars and can't settle for a stock sti no matter how well rounded it is...i am one of those "dare to be different" kind of people...hahaha... I would never settle for the 06/07 front end neither!

But after that whole thing....to each his own...just my .02cents
