I weighed my 5 spd at 47 kg with no oil on the bathroom scales.

I just retested the gearbox on some other scales and got 42.6kg. There is no oil in it though.
Not sure of the oil capacity, but I doubt it's going to be enough to make the difference.
I can't explain this......

Is the 42 kg one a post 2009 gearbox made by Mazda rather than Aisin?

I built up a collection of RX8 gearboxes when they were £50 cheap and because I was putting one into a MGB I weighed both 5 & 6 speed versions and
they were identical in weight. I also weighed the MGB OD gearbox and it was also 50kgs which is correct so my scales are accurate. It could just be a
variation in year of manufacture.

Mine at 47kg that would include the prop shaft knuckle, slave cylinder, clutch fork, thrust bearing and gear shift minus the knob.

no propshaft, clutch fork, bearing or slave, but there is a gearlever without knob
(hmm I hadnt thought of the fork - that's a part i'll need)
EDIT: in fact the clutch fork and release bearing are fitted

I received a delivery of a Jag Dual mass flywheel today. To my surprise the starter engages perfectly using the ebay adaptor plate. Why was I
surprised? I don't know really!
The weight of the whole clutch assembly was ~20kg

what clutch plate will you use ?
I hate dual mass flywheels I’ve never bought one that wasn’t knackered

Ive bought a standard RX8 one off ebay. It might arrive tomorrow....
The dual mass flywheel seems ok, although I've no real experiencew with them. ~1cm rotational slack. Still it was cheap enough for a trial
By the way what you you use for a clutch slave cylinder considering the engine gets in the way of th standard one? I've got it fixed using just
one of the two bolts right now but not that happy about it

Ive got the RX8 clutch plate and it looks fine. Same diameter as the Jag/Ford one. Obviously it also fits the Mazda gearbox
This is what I bought:
https://www.ebay.co.uk/itm/Clutch-Centre-Plate-fits-MAZDA-RX8-1-3-03-to-12-13B-MSP-6-Speed-MTM-236mm-ADL/333845171192?ssPageName=STRK%3AMEBIDX%3AIT&am
p;_trksid=p2057872.m2749.l2649
Pretty expensive I thought actually.....
But in order to assemble everything I need the flywheel bolt torque setting figure.
(Seems a nightmare to search for this and TBH the LB internal search function never works for me at all)
While I am at it I also need advice on slave cylinders and how to thread the oil filter take off/LH engine mounting
Advice appreciated

Slave cylinder I use a Mazda6 V6 one,you just need to remove some casting lines on the passenger side head of the AJ30.
Oil filter I use a remote set up,I've cut the engine mount up and welded on AN10 fittings.

Thanks for that. Ive gone with 115 kg/m oiled with loctite - I hope thats sufficient: it's pretty tight!
For the slave I see on ebay some v6 types but there appear to have offset mounting holes? Could you provide slightly more detail? (or a link ;-) ?)
For the oil filter, is the AN30 the same as your typical Mocal setup? I was thinking of a double ended adaptor threaded into the alloy bit rather
than welding... Actually It would be interesting toi see your LH engine mounting - Ive made up a steel box for the alloy thing, that bolts on in
several places....

For my remote oil take off, i used the Mocal plate and machined up a double ended adaptor stub (3/4" unf into the Mocal and M22 into the block).
Whilst my engine is a the ST220 version of the duratec, the blocks are the same.
