Floor Pan Swap - haldex to come...

Re: Floor Pan Swap - haldex to come...

That's true, it's pretty snug back there as is. A K04 should still fit though and if I go bigger it can be mounted elsewhere... the engine location is just a consideration in what I wanted to do with the driveshaft anyway - shifting it may or may not happen.

Since there are more TT parts around I think I'll just use it's driveshaft and then if I need a new one down the road it will be cheaper/easier to source.

I wouldnt move the motor back if you plan on going big turbo. On my stock location motor, there were only mm's to spare as is.

Haha... KUJI, I'd be all over that if I had a Ford Falcon... or Pinto... or Gremlin... or something

Re: Floor Pan Swap - haldex to come...

I had a Passat Syncro prop shaft shortened, cost about $100-150.
Most shops didn't want to touch it. It was the sort of thing: "European? No U-joints? We can't help you, sorry."

Lengthening is easy, you really just need to put standoffs (or a spacer disk) on the rear guibo and use longer bolts.

Or you might get lucky and find a thicker guibo from a BMW or (of all things) a Dodge Charger...

Interesting... those standoffs are pretty much what I had in mind. Once I know the bolt spacing of the TT driveshaft I could compare with what's available - thanks!

I had a spacer machined for my first 6spd swap on my a6. Standens did it for me, they also custom make and balance shafts, go there and ask for Brad Shier, you can contact me for my personal info if you are serious about talking to them.

Excellent - this sounds like just the kind of place I'm looking for... pm'd.

Re: Floor Pan Swap - haldex to come...

I'd be most concerned about getting perfect alignment installing the spacers, vs. a zero-balanced rear propshaft section built by a competent machinist.

Shouldn't be too hard to notch your mounts and nudge the motor/trans back 1/2"-3/4"?? Or is it different with transversal layout?

If the bolt pattern is drilled right it shouldn't be an issue - same idea as a wheel spacer... so this is def a job for a machinist -vs- hacksaw, grinder & determination. The driveshaft is already balanced but would be worth getting checked for sure.

I haven't measured anything yet but 1/2-3/4 should be fine. Aftermarket mounts seem better suited to this venture though - either order them custom or just modify a set.

My brother had to get his syncro driveshaft shortened and he couldn't find a driveline shop that would touch it. The last place he went to that said they would do it went out of business the next month.

Sucks for your bro - just needed to be a little faster on the draw I suppose.

I think he'll need to worry about front axle problems if he moved the engine back

Yes & no - just depends on how far you move the engine back. Too far and you would need to notch the frame rails which isn't too big of a deal. I'd be more concerned about leaving enough room for a turboz n stuff...

Re: Floor Pan Swap - haldex to come...

Good info, thanks. Def post up about your findings.

The reason I've been leaning toward spacing the front is so I can move the engine/trans back in the bay a little... that's a down the road thing but it would save messing with the driveshaft again. If the spacer idea is too fussy I'll just lengthen it, like you mentioned, or find an R32 driveshaft.

Re: Floor Pan Swap - haldex to come...

Just the two mounts that are attached near the midpoint - I think that's all that's needed as each end is bolted to something.

I'm not sure who I'll ask yet, but I'd prefer to use spacers at the transmission/driveshaft connection which will keep weight back a little... any suggestions on where to get spacers made? Once the TT transmission is in I'll bolt up the back of the driveshaft and measure the gap.

Yup those were the mounts I was talking about.

Just FYI, I compared my TT driveshaft to an R32 driveshaft. The TT and R front section are identical, it's the rear section that is longer. From what I've seen from researching, getting it extended is only $75-125ish dollars, I have some shops I am going to be calling. I'll let you know what they say.

If you put the spacer at the front, you'd be pooched if you ever got an r32 driveshaft cause the center mount would be in the wrong place.

Re: Floor Pan Swap - haldex to come...

Did you get the drive shaft support mounts off the TT?

Lengthening shouldn't be too costly, any ideas on who you were going to talk to about getting it done?
