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

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

Oh, ok. From >this post< I understood that the HEL units are good, and the same manufacturer (HEL Performance) is in the description on the saabits web, so it should be the identical one.

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

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/sh...=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!
