Need help with Sti 6 spd swap

[Christofuer]

Hey guys,
I’ve searched through this forum and I can’t seem to find a thread with my situation, if there is please provide the link and sorry for the extra thread.

I own a 99 Subaru Legacy Brighton wagon with the engine code EJ22. The clutch needs to be replaced along with other things and I eventually want to do an engine swap. Right now I don’t have the money for the full engine swap so I would like to swap out my 5 speed with the sti 6 speed transmission.

As far as I know it should bolt up but what other parts are needed to make this transmission swap work on a wagon?

Welcome to SLi.

There is no EJ23... You have most likely have the Phase 2 EJ22E. Look between your alternator and power steering on the engine and you will see the EJ22 stamp and your ID/Vin Plate on the driver side shock tower will say EJ22E.

Anyways. Yes you can bolt a 6MT to your Brighton but the cost of a 6MT w/ shifter & linkage | clutch | flywheel | clutch slave | 4EAT driveshaft is not exactly cheap. You're looking at $3500 on average depending on your source.

Where in "Canada" do you live? I am from Toronto, ON..

Thanks!

Haha you're right, I thought that was strange when I saw "EJ23" I misread it, it is actually an EJ22 it just had a 3 after the EJ22. :banghead:

Would I also have to replace the diff? I just don't want to pay $700+ to do the clutch and then kick myself later because I should of put the 700 dollars towards that swap. My engine runs amazingly well for having over 237 km on it and I really like the idea of having a 6 speed in there until I can afford the sti engine. I think our emissions laws in Canada won't allow us to have a version 6 or 7 jdm EJ20. Some mechanic said it wouldn't pass because of the ECU? but than others have said it will... I'm lost.
I'm also from Toronto it would be cool to meet up and talk cars man are you on TSC?

[chuckthefuk]

Your car is a Brighton 5MT so your final drive is 3.90 which is the same as the USDM 04' 6MT and the JDM 01-04 sti. So your good on that end.

You can run legally with a any EJ20/25 motor with a WRX intake manifold + sensors and a WRX ECU. Period.

TSC? Yes sir. I am Chuck@SevenAuto from http://www.sevenautomotive.ca

Give us a call this week @ 647-693-4948

I will talk your ear off if you come in for a visit :-D

Yeah I'll have to come by some day so we can talk its just easier than talking on the phone. Hopefully within the next year or two I can learn enough to be able to drop the engine in myself. Thanks for the info though I appreciate it!

[chuckthefuk]

No problem.. I can give you a detailed list of items.. but you know.. $$$$ ... no point if you don't have it :-p

[Christofuer]

It's not really about the money, it's about finding the right shop

[chuckthefuk]

Canjam. Fourstar motorsports. Gord bush. Yoshio. Are some to look into.

I have 99bk L phase 2 5mt. Does your information apply the same to mine in regards the swap. Yes it's expensive. But I have a phase 2 with 200 miles on it all new everything but block. I would want the Sti front and rear diff also. Thanks.

The STi front diff is located in the 6MT. Different front diffs come in different models. USDM/JDM/Euro


If you are trying to use the rear diff R180 from the STI you will need the matching axles and rear hubs + brembos to make this work. OR.. You can use the rear diff R180 and make custom / hybrid axles to fit the rear hubs on your BK.


The rest is straight forward installation. As long as you donor parts come with the supporting items such as transmission crossmember w/ mount , Shifter Linkage, Reverse Lock Out Cable, Slave Cylinder, clutch, flywheel, pilot & release bearing.

Thank you Chuck. I'm Lane. I have been going over the boards and am gathering insight at a fast pace here. While trying to learn as much technical data. I saw your post in the brake upgrades section and gained tons of insight which can help here with the trans swap. I'm gonna do the JDM Sti GC FHI brakes or 06 wrx on the stock axles by getting the brake kits and the hubs with backing plates. So that leaves the axles stock removing the Sti rear drivetrain idea. I'm going with the 6mt, the bell housing swap and auto drive shaft. Then I can keep stock axles and bolt the Sti brakes on that because that's all I wanted really not the LSD controller and all that. Car has stock power that's a waste of money and more to maintain and break. So I'm gonna find a 04-07 6mt complete swap. Is the clutch and flywheel in such package already such an upgrade on the stock BK L that no aftermarket is necessary. Will never exceed 180hp and that would be when I drop the 96 2.5 in for its low end torque. That's 200k miles from now I hope. Thank you.


-edit....should I go USDM, Euro, JDM 6mt. You said the front drive gear is different in each. I'm looking for low end torque city driving. No track use. Thank you.

Hello Lane,

Sorry for the late response.

Its recommended to use the 2004 USDM 6MT since the final drive is 3.90 (which matches your stock R160 rear diff) and has a 1:1 center diff. Using the USDM unit will provide proper gear ratios for highway speeds compared to the EDM/JDM units which are geared for shorter runs.

There is no need to upgrade the clutch to handle more power as you stated 165 bhp. The flywheel can handle 500+ AWHP with no need to upgrade unless your looking for a lightweight unit to increase rpm during up/downshifts.

That being said you do not need to use an aftermarket DCCD (Driver Controlled Center Differential) however installing a unit such as "Neetronics PDC-01" will allow for more "fun" down the line but again its not necessary.

I am glad my brake thread was useful during your research and the FHI JDM 4/2 pot combination is actually overkill for such low horsepower... but is still driveable.

Let me know if you need anymore info.
