My '91 744 B204GT project

What fluid will you be using?
I have some Febi API GL-4 75W-80 laying around so I wanted to use that, but reading now the >M90< topic I'll check with Volvo dealership. The issue is that the recommended 1161745 (GL-4 75W-80) seems to be no longer available and it's official replacement 31259380 is different spec (GL-5 75W-90). Not sure what is the best way to go here...

EDIT: Dealership responded that the replacement is #31280771 (API GL-4, SAE 75W), it replaces Volvo Transmission Oil 1161645 (API GL-4, recommendation for M45, M46, M90). So that one is ordered and will go in.

Transmission filled, sealed and ready for installation :nod:

I have also ordered stainless braided clutch hose as I have been reading bad experience using the oem hose with a performance pressure plates.

Productive evening today...stock valve springs replaced by the Ford 4.6l ones (Melling VS1268). So relaxing job when you have the right tools! :-P

EDIT: Hmm...just noticed that the manual says to put closely wound coils at the bottom. So few of them to be flipped :)

Looking good!

I don't wanna derail the thread. Would you please post up the part numbers for those seals in the M90 thread? http://www.forums.turbobricks.com/showthread.php?t=94325&page=23 I need the seals for my M90. (I have quad square US 740 headlights for trade.)




I am interested to see the powerband with this engine/gearbox combo. My setups were freeway screamers and not stump pullers. What tire size and rear gears?

The seals that you can still get from the dealership are the input/output seals 9183891-1 and 6843480-1 and also the 978268-1 O-ring.
Other than that you also need the shift linkage seal (Corteco 01019151B, NLA from dealership).

I am using 205/55 R16 tires and 3.73 ratio. Of course also very curious about the way how it behaves on the road :)
 
New bigger pistons from Yoshifab finally arrived, so I've gapped the piston ring ends and installed the pistons in the cylinders...hooray! :cool:
