P80 Platform 6 speed discussion

egg@VolvoMike When your ready, do make a build thread. I'd be interested to see the rest of the car if your going to the expense level of sequential box...
I thought the 850r dude was your buddy chiming in. Haha
I sold @au_850r his wagon, built the engine and performed the manual conversion. I organized the respray and even put it on ebay while he owned it.... I honestly don't have time to do build threads and my own 850R is a bare shell after a respray 18 months ago.
The track car getting the sequential is getting a built S60R 2.5 engine with rods and pistons, hi flowed K24, Do88 radiator, intercooler & RIP kit, COP & dual VVT with a Vast 4.4 and twin plate clutch. It will run KW V3 coilovers with S60R 330mm brembo conversion on the front.

Build thread or it didn’t happen ?
@VolvoMike I was of the understanding you'd need a aftermarket ecu and e-throttle for torque control, for shifting to realise a sequential boxs' capabilities?

Will use the multi purpose output in the ECU for flat shifting.
On another note, does anyone have an old 850R clutch pressure plate? I'm needing one just for the test of the M66 conversion. Or, if someone has a brand new clutch (Volvo 272218) and is looking at doing the conversion, I'll supply a brand new clutch disc they can use in the M66 for loaning me a pressure plate.
Yeah, so one of the things that is great about this forum is that it avoids the dumbest parts of FB - including the sedan vs wagon crap.
I don't have FB and don't need it. To many fake and false people so I agree totally all of that is avoided on here
@VolvoMike would a new pressure plate for an m90 be suitable? Im pretty sure one of my customers has one left over from a 740 manual swap

Possibly. My 20 valve NA car has a 230mm clutch disc and cover but need a 240mm pressure plate like the 850R has.
I'm pretty sure he ended up with a Franken-clutch setup. Flat redblock flywheel with upgraded falcon pressure plate and 850r clutch disc. He's going to dig it out for me today I'll let you know
So I ordered a new twin plate clutch kit that I'll need later.... hopefully it can hold all the powers and torques that the 20 valve naturally aspirated can throw at it!!!
I was given a used XR5 clutch kit and flywheel which has been fitted to the engine and hopefully back in the car over the weekend.
By my calculations, there’s a fair chunk of money in that. :)
XR5 fitment?

They're cheap compared to the sequential that will ultimately end up in the car... I blame @timbo as he is a bad influence on my wallet. They suit the S60R along with a few others but no need to acknowledge Ford fitment in a Volvo.

So... it's all done!! I now have a 6 speed 850 driving.
Using the S60R mechanism on the XR5 box puts the gears the correct way and drilling out the ball for the sideways gate movement makes it work perfectly with the standard 850 gearshift lever with no other modifications required.
Is the s60r box mechanism going to be the same as the other m66 volvos?
So shifter cradle and cables are 850?
All the P2 manual M66's will have the same mechanism, petrol or diesel won't matter or you can make your own and shorten up the shift from odds to evens. Modifying the XR5 cable ball end to take the 850 cable makes the cross gate narrow but it feels nice. It would be possible to increase the height of the cross gate mechanism to widen it if preferred.
Nothing inside the car was changed and original 850 cables are used.
I cut up the M56 cable mounts and cut off the XR5 cross gate mount (left hole) and welded the M56 in the exact same spot. It would be possible to grind out the hole to suit the 850 cable but this was quicker. The throw cable mount was then welded after centering the shifter inside the car. I'll compare it to the S60R cable bracket but the gearbox will come with one so no need to buy an extra part.
The thermostat on the airbox had to be removed as the S60R mechanism hits it but it still just touches the underneath side of the airbox. I plan on making my own short shifter so it won't be an issue.
Ask for the clutch line to be included with the gearbox you buy as you'll need it to modify the original M56 one to work.
