Recommended Posts

Can someone please clarify before I buy the wrong part? I just want to drive my car again!!!

 

3 options;

 

1) Call Driveshaft Specialist 1-866-455-6622. Talked to Jeff. They have the info. on my drive shaft. Front shaft 24.12", rear shaft 36.12". Uses 1310 XL u-joint & 2002 Forrester Wagon A/T carrier bearing with 05 LGT carrier bearing mounting bracket to bolt to the drive shaft tunnel.

 

2) 07-09 Spec B driveshaft, and replace the differential's input flange with the R160 flange. If you using a R180 rear diff.

 

3) 05-09 Legacy 4EAT driveshaft ,Over all drive shaft length should be about 63"

I'm not at you power level. Last dyno at stage 1, I was at 240ft@3000 rpm. (now stage 2) I used Stock 05 STi clutch & SMFW. At over 100k on OEM until. It still holed full acceleration with a 3500bls. car in tow. IIRC, I think the OEM is rate to hold between 350whp-400whp.

I dont believe the 5 speed one will work as I remember. If it would have I would have kept my 5 speed ACT clutch and used it in the 6 speed. As it would not I sold the WRX flywheel and ACT clutch that was in my 5 speed with only 30k on it.

 

also a previous post in another thread on the driveshaft....

Worked perfect in my Outback XT 6 speed swap.

 

Check Ebay, there were a lot on there from 75-150 bucks when I did mine

Let me go to my garage an check my theory out. Going to see if 6MT pressure plate will fit up to the 5MT's FW. And other thing you can check on. Is the JDM 04 STi was 5MT. Need it see if it was a "push" or "pull" type clutch action. If it's a "pull" like the currant 6MT's. Then you mite need to just replace you pressure plate.

Sorry I must of scrap my 5MT's DMFW, clutch & pressure plate. I can tell you that the 5 & the 6MT's have the same spline.

 

The 5MT's is a "push" Through the action of the slave cylinder, pushing on the clutch fork. The TOB is "pushed" into the pressure plate finger. Releasing the clutch.

 

The 6MT's is a "pull" Through the action of the slave cylinder, pushing on the clutch fork. The TOB is "pulled" away from the pressure plate finger. Releasing the clutch.

05-09 4EAT Legacy drive shaft fits. Outback is built of the same platform. It should be the same. To make sure, total length is about 63."

IIRC Scooby2.5 4EAT Legacy drive shaft measured 62.5"

On second thought, it looks like there's more to the AT-to-MT swap than I thought:

 

http://legacygt.com/forums/showthread.php/another-5eat-6mt-5mt-swap-questions-05-lgt-thread-132374.html

 

The crossmember that supports the back of the AT doesn't bolt up to the chassis in the same places as the crossmember that supports the back of the MT. This can be fixed with a welder. :)

 

The AT ECU gets confused when the TCU is missing, and it reports a CAN error on the trip meter. This might be fixable by flashing an MT ROM onto the AT ECU but that hasn't yet been tried.

 

And of course the AT instrument cluster has the PRNDL thing on it. I suppose that's what DRoc to ask about swapping the cluster... I'd forgotten about that little difference. I guess I have to retract my earlier statement that he was over-thinking this, actually I was under-thinking it. :)
