Default 05 LGT and 05 Saab92X Linear

I have an 05 Legacy GT(auto) and an 05 Saab 92x Linear (manual)

I love the Performance from my LGT but the 5EAT is just boring and it bangs into 4th sometimes when shifting not under boost, but the engine runs great and has lots of life left.

I also have an 05 Saab 92x Linear that has a Manual Transmission but the engine has almost 200k but still runs pretty well.

I would like to combine the Lgt engine with the 5 speed, im trying to figure out if it would be easier to swap the engine into the Saab or swap the Transmission into the Subaru....

any insight is much appreciated.

Hi,
Since this is getting no responses...you'll have to read mine.....and since you live in Vail (skier or boarder?), I'm hoping to make it back there in a year....I might need a place to crash. :-)


anyway.....

Always easier to swap in a 5-speed. However, there are probably more than a few threads spread across the Web of those that wish they hadn't. The TCU/TCM and ECU/ECM of these along w/their associated systems - ABS, Speedometer, etc. - won't like what doesn't match.

If you're willing to do a complete harness swap - But Why? - maybe this would work.

Seriously, I'd consider getting an upgraded Torque Converter and Valve Body on your 5EAT - first....Actually, get a low mileage trans, swap in the upgrades and THEN put back in your LGT and get a Tune. I did this on my '02 WRX and it did make a difference.

If you've gotta have a boosted 5/6-speed, then buy one....but please don't buy a used Subaru Turbocharged car w/out knowing its complete history AND still doing a compression and leak-down test and having it fine-toothed.

And I hope you're watching your VF40 for its inevitable disintegration. Get rid of the oil feed line screens, too....and hopefully you're doing an UOA on a regular basis to see how your bearings and HG's are doing. Those ringlands still in good shape?

Watch the HG on the 92x, too. Otherwise, it's probably the more reliable car. But @ 8,100 ft ASL, I get that the NA 2.5 is more like MIA.

GL,
TD
