Default Has anyone swapped a 5mt into a 4EAT EJ25?

I know KhaOs has done this on his WRX and the webmaster of LegacyCentral.org did it with his turbo BD but has anyone swapped a 5mt into their 4EAT EJ25? I've been itching to swap a 2.5rs 5 speed into my '99 Legacy and I've now got the better part of my $2000 parts budget together. Anyway, I'm on the lookout for parts at this point. I've talked with the owner of legacycentral.org who has this process well documented from his manual swap into his '93 Legacy w/ Turbo conversion. Here's his writeup
So far, here's what I think I need:

Transmission
Clutch
Flywheel
Pressure plate
Pilot Bearing
Throw-out Bearing
Driveshaft
Shifter assembly
Pedal assembly, (brake & clutch)
Clutch master and slave cylinder
Hydraulic clutch line
Starter Motor
3-piece rear crossmember

I've been told that on the EJ25, the MT and AT ECU's are different. Can anyone confirm this?
Any ideas at this point?

OK, very slowly.

ECU is not a factor in my swap. Remove the TCU (trans) and you're good to go.

Good luck with your swap.

Once more thing you may need would be the rear diff to match the transmission gear ratios. Mis-matched ratios are bad news!

That's good to know. Subaruparts.com seems to have different ECU's for manual and auto EJ25's. Could it be possible that these are the same and I just have to enable/disable something on my existing ECU?

I'm working on it in my RS....WRX 5MT into 4EAT RS. I have all the mechanical hooked up, revese ligths work, brake lights work. I'm going to be running a Tec-2 standalone ECU. Running the stock ECU you will most likely have to wire in the neutral position switch and you will need the MT ECU(they are different). Another thing is that you will have issues running ABS, your 4EAT has a TCU(Transmision Control Unit) and there are several systems that are wired differently in MT vs AT, 1) ABS, 2) Reverse lights...the brake lights seem to work fine without the TCU, and I have seen a post where the guy had got his ABS working I believe....Not a priority for me now..lol Hope this helps...your mechanical parts list looks about right

Boost,
So it sounds like I should add the MT ECU to my list. Any idea who this could be who wired up his ABS?

just to let you know ive got everypart needed for you swap(other then the pedals and ecu)


near everything youd expect is aftermarket and very high quality(sti, act, jun) the trans was rebuilt less than 3,000 miles ago and i live near pittsburgh so you can come see it in person and not have to pay shipping

I haven't thought about this for a week or so as I just spent a lot of money on a header-back exhaust. However, it sounds like Sybir is about to start the swap on his 4eat Legacy Outback, so that's promising to hear.
I'm wondering what I should look for in used parts? Is the only real wear part the clutch? Should I worry about pulling a junk-yard transmission if I'm planning to replace the clutch anyway? What else could possibly be abused?

The ECUs may have different part nuimbers, but I'm running an AT ECU, and, with the addition of a single pin to the wiring harness to ground, the ECU stopped looking for the TCU, and instead occasionally informs me of a failed neutral position switch (which isn't even hooked up).

So, at least, on the WRX, you don't need a different ECU.

in a legacy, you cant just throw in a MT ecu into a car that came with an auto.

they have a few different pin locations. MAF sensor pin is different. and a few other minor things.

keep the ecu that you have.
