So the foremost section of the driveshaft, just ahead of the U joint, is longer on my 99 LGT driveshaft than my SVX shaft. Just slightly. I'll grab a pic tomorrow evening.

Also, it's not the snout bottoming out in the trans as I previously thought, it's the trans bottoming out in the dust-shield-cup thing at the head of the driveshaft. I ground away the two tack welds holding it in place and it came off with a little bit of hammering.

And it's CLOSE. I'm going to grind down a wee bit of the base of the snout and report back.

Anyway, I already drove it. It was awesome. It was still smooth with the welded mount, it felt extremely solid and nice in fact, but the gear whine is rather loud. I need new exhaust gaskets before I can say if I can live with it. Plus it could just be the trans on driveshaft friction. But without the slushbox soaking up torque this car moves pretty well, and I haven't even disabled torque control. And right when I got on it, it minced the accessory belt. POWAAAHHH!

The shifter stood up out of the center console a little to high, so I chopped the top half of the threaded tip of the shifter and ground away the ring to allow the knob to sit very low. Worked a treat. DIY short shifter BOOM! I may yet go lower...

Mitsuko is the brand of the clutch disk and pressure plate, but I believe the kit was put together by Grip Force? Everything seemed of decent quality and installed/ fit easily enough. The clutch pedal feels oddly light however, I was expecting more weight with 'Stage 2' but what do I know?

Thanks, there's plenty to keep track of!
I wouldn't say she's on the road just yet, I had no hood and for the second half of the drive no accessory belt!

She's a beast!

I've been driving my SVX around for the past two days and I'm in love with the car all over again. After reassembling the exhaust she developed some leaks. I guess the rust was acting as gasket material...

And holy gear whine! Reverse is rather loud, and all forward gears have some volume. It's like a race car if this was my Legacy, I'd keep it as is, it really doesn't bother me, and it's louder inside the car than outside.

But this is an SVX. I believe this car deserves to maintain a certain level of refinement, so I'm going to revamp my crossmember tomorrow. I'll see if I can get a CAD savvy friend to do a proper iso/orthos.

BTW, anyone else doing a MT swap, if you neglect to lengthen the wires for the VSS, your car WILL run like crap. Right around 3k- 4k rpms the car would buck and surge with more than about 50% throttle. I assumed it was because I have no check valve for the iris. Can't wait to see what happens when I get a new one of those!

Stay tuned for a PROPER crossmember.

I can definitely agree on the gear whine! My Legacy's 6-speed also whines but much more quietly. There might be a combination of engine and trans mounts that will isolate the noise from the chassis and still give good performance (I'm thinking stiffer engine mounts and a softer trans mount), but I'm planning on adding some soundproofing to the trans tunnel to see if that helps. My pre-cats don't have heat shield so it gets fairly toasty in there.

If you do the crossmember from scratch I think you can shave a fair amount out of it. The OEM SVX transmission brace needs so many bolts to provide some front/back twisting resistance, but since the MT crossmembers are a ladder structure you really only need one bolt on each back corner. I'd love to make a full tubular crossmember and remove that boat anchor stamped steel part.

However.... That brace might act as a chassis stiffener in addition to being the transmission support. If that's the case then stripping metal out is counterproductive.

Re: 5mt crossmember schematic

I have pictures of my modified pedals and shifter (6-speed) here:

http://smg.photobucket.com/user/craz...?sort=3&page=1

The transmission mount is more of a build in place sort of thing. Install your transmission and use a jack to support the tail in the right place. Install the OEM trans mount and cut where required for clearance. After that you need to install two bars lengthwise between the trans mount and the round tube below the flywheel. With that basic structure in place you can come up with a plan to fab a cradle in between that will hold the actual transmission mount.

You can check out TomsSVX's locker for some of his pictures:

Okay, so as I mentioned before I have to revamp my crossmember a little.

Would you guys be interested in a fully redesigned version that does NOT involve the original svx piece? I'm toying with the idea of a very minimalist design, a single bar/bracket that would cross directly beneath the trans mount and only attach to the body with new bolt holes. Simpler to make, and hopefully easier to install.

The other option is the commonly seen svx crossmember connected to the torque bar. Regardless of what I come up with for a schematic, this will probly still require access to underneath the vehicle to make a perfect fit. The plus side is you won't have to drill any holes in your baby.

So what do we want? I'm leaning towards the former option more and more...

Re: 5mt crossmember schematic

Just had a thought; the svx crossmember is bolted to a reinforced section of the body, and my new preferred location is likely to be nothing but flimsy floor pan... I'll have to take a look under my car tonight.

I'll be under the old girl later today, anyone looking for specific pics? I'll try to get an overview of the underside of the vehicle across several pics.

You'll also get to see my atrocious (but functional) crossmember.

Re: 5mt crossmember schematic

Ended up having to deal with an exhaust stud which is actually a bolt now after the stud stripped out, and appears to have cracked the block and now leaks coolant. It's the foremost stud on the driver side manifold. At least it only leaks when the bolt is removed.

Fyi the bolts that hold the driveshaft carrier bearing to the car are the same thread as the exhaust manifold studs, but a little longer. (Too long perhaps)
