3b s2 coupe resurrection

[andy10v]

nice additions there Andy

Thanks, have you swapped your diffs over again? If so were you able to do it without dropping the sub frame? Also did you get the tools for setting the backlash etc?

[Acidburn]

Yes you can do it without dropping the rear subframe, me and s2driveruk did his, its not too hard just a pita and make sure before fitting you leave it on a bench for a while to see if it leaks from the rear seals.

[andy10v]

Excellent, that's what I wanted to hear, thank you.

As far as diff oil as I have never had an issue with 100k+ oem stuff I am inclined to just bung new oem fluid in; opinions?

[Error404]

yeah can do it without dropping the subframe its just a bit fiddly getting the driveshafts onto the flanges

Seals leak when they aren't in straight
Make sure you check the backlash before refitting, I still need to do mine, been to busy recently

use a decent synthetic GL4/5 75w90. I use Fuchs GearSyn from GSF, good value


I'm toying with the idea of fitting an electric pump and oil cooler to my torsen now its off again :mischeif:

Thanks for the information, appreciate it.

Diff oil cooler-keep temps down on track days?

[andy10v]

New rear diff mount fitted, those allen key bolts are a bit of a pain to undo, easy once the allen key is adjusted with an angle grinder :mischeif:



A bit better but the big bang is still there , lying on my back if I grab the prop shaft I can pull down on it and get a clunk so the center bearing carrier thing is the next thing to replace I guess.

[Error404]

yeah worth changing the prop bearing if theres any play in it mate

The torsen's generate quite a bit of heat when driven hard, i think this is why Audi fitted an oil cooler ot the DSY box

[s2driveruk]

funny, i'm about to do the exact opposite and remove the powerflex and shove an oem back on lol

[Error404]

I'm doing the same once i've put a new bush in the housing, PF one if just not smoooove enough

Little Update

I got the car running properly

Changed the mfts and mfts plug/loom as suggested (and supplied) by Steve (thank you again). The back of the old plug was green and foosty and partially disintegrated upon removal. New one fitted and boosts to 0.8 bar and stays boosting properly. Temp guage working properly as well.

Still to sort my clunk, however I have the parts to do that now (I hope)



New rear diff mounts and gearbox mounts as well hopefully.

And as the car is now running as it should it may even get these;

[andy10v]

I was looking at the center prop mount and thinking of filling the void in the new one with some poly rubber stuff, any thoughts?

[A80Avant]

when i used that briefly, i fitted it backwards in order to make it work, otherwise it still hit the chassis and made noise. Then Rob sourced the proper part and no problems thereafter!

[Nj]

would that not stiffen it up and risk getting additional vibration? Only one way to find out though Do you have 2 mounts so you can revert top normal if you make a b0ll0cks of the other by filling it?

Noted, thank you. How much was the original part from rob? I spoke to audi and they said complete prop at ££££

I was hoping to support it as it looks like it will tear again fairly easily. No only got one and would rather only do it once.
