Well my 2003 transmission 3rd gear syncro is dead!
I have a lead on a 2008 transmission with the concentric slave cylinder style locally, for a really good price.
Is it worth to presue this swap?
I will need HR style clutch and flywheel? The CSC itself?

Any tips? Not much info I could find so far.

 

You will need an upgraded CSC and WillWood Master Cyl. Both can be had from Zspeed.

 

Ok, so the HR style clutch AND flywheel?

and the correct master and slave.

 

Before you get all giddy about this, I thought there were more differences than that, otherwise I would have had an HR transmission in my old Z

 

There's a thread on this somewhere regarding HR trans in a DE... aside from the bellhousing difference I don't think the input shaft is long enough (or short, can't remember). The guy ended up swapping the input shafts out and it was a *huge* PITA due to bearing sizes ect.

 

I am glad you knew more than me, I didn't want the OP to waste a bunch of money on this.

 

I believe the starters are on opposite sides as well. I know my HR starter is buried low on the driverside.

 

^^ Hence why I think the bellhousing needs to be swapped along with the input shaft.

Here's the pain involved:

Ok, thanks for some good info there.
