Hi All,
I am going to, well like the title says, pull the M60b30 out and drop in a M60b40. I have googled my little digits off, and it's not that uncommon, well it's pretty uncommon here only because we don't have a lot of 5 speed 3 litre v8's around. Some swaps have been good, some not so good, none of them cheap. I want to keep my 5 speed manual, so I have a few issues there. Many have done all sorts of things with flywheels, pressure plates and clutches, mine will be no different I guess. However I am wanting to get a custom flywheel made as I have found that in theory at least it may be cheaper, than going aftermarket.
Oh for those that don't know, the reason I am changing the flywheel at all, it that the B30 has done over 300k, I am guessing that the flywheel has done its dash, I don't hate the oem dualmass, but it is going to go. I have heard the B30 stuff wont last long behind the B40, and even if it does, wear will be accelerated due mainly to the increase in torque so for some assurance I may as well change it now. There are no aftermarket B30 clutches, clutch kits etc. So I am working on a cunning plan, gleaned from many hours on the internet. To be fair the engine has yet to be pulled, and only then will I really know what I am up against.
The reason for this thread is that I have not been totally happy with the info I have seen thus far. It's like no one has been really happy with whatever action they have taken, in terms of really nutting out what you need, don't need and should not do. Most of the info is from the UK where they like to transplant the v8 5 speeds into the E30, which is even more work than what I am hopping to do that's for sure.
It may help someone in future.
I will update this as best I can
