I have heard it said before that some ordinary plus 4 models may have been fitted with LSD depending on what the factory had in stock at the time. Have you tested yours?

Cheers Doug, I was hoping you'd say that
TBH I've not tested Monty for an LSD yet but it is something I've been meaning to do, if it stops raining tomorrow I'll wheel him out of the garage and get the rear wheels is the air, however, from the way the car drives on the limit I'd be very surprised if Monty doesn't have a limited slip diff.
Plus 4"s also got the LSD. I think it's more common than you might think.
Thanks Dave, this supports my suspicions and Doug's results when he checked his, as I understand it the VVT Mazda L/Duratec Supersports was released in 2011 and clearly advertised as having an LSD, so perhaps it made sense for Morgan to standardise from that point on meaning all Duratec Plus 4s from 2011 ended up with the same LSD axle fitted to the SS?
It is a guess though, what I do know is Monty was built in late 2011 and first registered in early 2012 as such the car benefits the Mazda MX5 box which really is a delightful transmission to use. Much like the Mulfab front wishbone conversion Monty came with, I freely admit I had no idea about all this stuff when I was bidding on the car. All I knew is I wanted a galvanized chassis port injected Duratec Plus 4 as I felt it was a bit of sweet spot model, to me the direct injection, drive by wire throttle and autophoretic coated chassis of the the later GDI Plus 4 are not improvements.
If it now turns out I also have a limited slip diff as I strongly suspect I do, I'll be delighted as it fits nicely with my attempt to create my own interpretation of a Supersport. A Supersport with a better ECU, a long runner inlet/plenum instead of ITBs, wishbone front suspension….. plus the practicality of an Easy-Up hood and a spare wheel, neither of which I’ve seen on a factory Plus 4 Supersport.
An LSD would just complete the Monty SS spec nicely
