What is the correct tension for 6G74 3.5 and 6G75 3.8 mains saddle?

Graham has been checking Mitsubishi and Haynes manuals and there are differences.

For 3.5 6G74 Mitsubishi quote 93Nm while Haynes say 70-80Nm

For the 3.8 6G75 Mitsubishi say 74 +/- 4Nm (ie 70-78Nm)

So is it 70-80 like Haynes state and is in 3.8 manuals, or is 93 correct? Both engines seem to use the same bolts and saddle interference fit so should be the same tension.

Cheers,
Alan

My Ellery's manual say's 93nm for both 3.0 & 3.5 if thats any help.

Have you checked the 380 workshop manual in the Tech Torque Sect.?

Yes, and I've checked the 6G75 US model Galant and Eclipse manuals too. All say 74Nm +/- 4Nm. Graham also found the 4 bolt 3000GT Turbo and apparently its 74Nm too.
