Default tranny or engine swap first?

so i just got my 2.5 rs last year, and I love the car, except for the fact that the dang thing is an automatic. haha so i'm just trying to figure out what i should do first...... should i put a 5 speed in and wait on an ej25t swap? (STi) or should i put that in first, and do the transmission???? i've been stumped for a week or so .... hahah so i was just trying to get some advice from some nasioc members. which would you do first??? btw... the swaps will be about 3-4 months apart...

Do it all at once. Why split up the jobs? Its easier to drop a whole drivetrain in at once than to piecemeal it.

i would do the 5 spd swap. I have a outback sport and love the thing to death for the simple fact that it is a manual. it will be a completely different car with the 5 speed.

plus the fact that i dont think a 4eat could handle the ej25t (assuming you are thinking sti).

edit: especially if you cant afford it all at once.

i would also go with the 4.11 gearing instead of the wrx 3.90. But thats pretty much a preference. the 3.90 will have better gas milage, but the 4.11 is shorter.

hmm.... considering i am turning this into a track car (dd for now) and am waiting about 2 years to get an 07 sti, not too worried about sellin it. I love the car, and it's in excellent shape. just want to make it a little more.... fun. but i still cannot decide. I really want the power of the sti........ but i really want the control i will have over my gears in an m/t... this decision sucks. lol. and every day i wanna do somethin different.

All at once as it will require a lot of work including under the dash.

Keep this one as the DD forever, get the STI in 2 years and have fun with that. Swapping an STI engine and tranny into an '02 is a waste of money that you will never get back. If you are going to spend the money on an STI anyway- why not save the mod money and get the STI sooner?

Gas mileage is bad and top speed is limited to 125 mph. But it sure is fun!

dude if it were me, the only reason id swap is if i owned a 2.5rs, or a wagon.

I have a wagon, bought for 6k. a rolled sti shouldnt cost more than 12-15k, and after that its just a few weeks of swapping parts. it makes it alot easier that way. the only reason a rs swap would be feasible is if you reason that you have an sti and are paying rs insurance.

put the numbers on paper and do the math, and see if it is doable for you. Personally i hate credit cards, because its stupid to spend money you dont have, and dont know if you will have in the future. No car is worth going into financial problems for.

if you must swap, it runs about 15k if your going to have someone do it for you, as i was quoted by garage tuning. thats 5k in labor and 10k for a full v8 sti drivetrain.

well i know a subaru mechanic and he is only charging me 600 dollars labor and i found a tranny with most parts for just over 1,000 so it's nowhere near that expensive, so i think i'm just going to do tranny first.

Default what about the opposite - 5 speed to automatic

sounds crazy - but I got my hands on a 2003 Subaru Outback Limited - but it's crushed from the drivers seat back - - the engine has 22,000 miles on it - - yeah - very low - so I've been looking for bodies that I can put this engine and transmission into....

I found a 2003 Impreza Outback w/5 speed - but not sure what or how the tranmission versus auto would work?

I know a mechanic, and the car with the low miles was practically given to me, so just figuring out my options?

Any advice? anyone?

lol idk why you would spend so much on a swap like this... id say if ur not doing it all at once do the tranny swap so it doesnt blow when u put the 25 in... if it were me though i would sell it and just get a used wrx for a cheaper price...

Sell your car and start over.

You could get a FULL STI swap for under 12k parts and labor. Match that with a 2000$ 1.8 liter fwd Impreza L and stock for stock it will wipe the floor with any STI.

I know because I'm helping to do exactly that at this very moment... Except that the Impreza was only 700$ and it will be converted to a widebody for a few extra thousand.

^^ sounds like a good idea, but considering the fact that i'm paying to get this done, i'm not going to want to drop an extra 10k on labor havin somebody do that. i might as well just get an sti if it comes down to that, but like i said, i'm stuck with this car for a while.

The motor can break the trans, but the trans can't break the motor. Do the 5spd swap to keep you happy. Or just trade for another car with a 5 speed.

Setups like this make little sense to do in GD Imprezas. Sure you get lower insurance rates, but what happens when the motor gets trashed? They'll look at it and only cover the amount for a stock motor.
What happens when you put in that 300hp motor and you still have the stock brakes, suspension, sway bars which quickly get overwhelmed by that amount of power?

It is 5000x easier to just sell the car and buy a car that has parts that are made to handle that amount of power. Get a GC/GF and do the swap, or get another car.

Bzzzt. Wrong. The 4EAT can handle 300chp all day long. Do you think ESX uses auto trannies in their 9 second drag car because they suck and are weak? I've got a friend here in Colorado with an EAT mated to his 400whp Ej257/Ej205 hybrid engine.

Now if you don't like the auto that's another story, but to say they are weak is just uneducated. There are some minor things you can and should upgrade if you want to throw big power at them, but nothing that's a budgetary deal breaker when you are in the midst of a swap anyways.

I'm with the people saying sell the car. Hell, you can get a good running bugeye WRX for what you will pay for the STi swap parts. From there you can get an Ej257 bottom end, bigger turbo and tune for a couple thousand and be equal to the performance of your proposed STi swap and have spent thousands less. So, explain to us why you can't sell this car?
