I'm tearing down a Mk2 1.6 MX5 to use the drivetrain in my 'locost' oldtimer replica. Dash out, seats out, most of the wiring out,
brake servo, pedals etc all relatively easy to remove. Now getting to the difficult bits: Removing steering column, exhaust system etc.
Does anyone living near Staines/Egham have a bit of spare time to come to my shed and talk me through what else needs to come off? There is ample
online advice about how to lift off the unibody, but not a lot of detail about everything that needs to be removed first. I'd rather not
discover I've overlooked something when I'm actually trying to lift the unibody! If you done it yourself, you are sure to know :-)
Thanks to all for this video. It's entertaining and I've learnt a fair bit from it but if I'm being critical, it lacks some of the
detail I really need. Nice to see I can apparently leave the exhaust system on, and I know I will regret having been a bit cavalier with removing the
wiring.
I'm trying to do this all with just two hands! If there is anyone else around in Surrey who's doing the same I'd welcome getting
together. Shared knowledge and four hands would be nice!
If you're only you and no-one else I'd strongly recommend removing absolutely everything you can. Just from the point of view of getting
it as light as possible to remove it. I did it on my own and even with everything removed it was still hard work. It also makes it easier to take the
subframe out from underneath, or take the unibody away. Less things to catch on.
To be honest, the actual fixing bolts are the last thing to be an issue. For me the main problems were the suspension points and the lambda sensor.
The former was because the top mounts go into the bodywork, so you need to either brace the suspension somehow or have the subframes sat on something
before you lift.
The latter was just because I'd missed it and I heard the 'ping' as I apparently tried to lift the entire subframe up with the
sensor wiring!!!
Having never seen a stripped MX5 before, is there anything substantial to the part which connects the front and back subframes? It seems a bit
excessive to have that, given there's the monocoque/uni-body. I presume it doesn't provide structural integrity independently of the
'bodyshell'?
if you want a really detailed hands on video guide for disassembly and rebuild of an mx5 I recommend looking at

It's fairly rigid, but you're correct in that it doesn't provide proper structural integrity. It's more to improve the
connection and alignment between the gearbox and the diff, something about improving the 'feel' of the car. When it's removed (or
even when it's replaced but not correctly aligned) it can make the car feel 'yucky'.
From memory cars like the Mev range retain the PPF and it's characteristics, whereas using an MX5 as a donor in a seven usually dispenses with
the subframes and replaces the PPF with it's own chassis.
Many thanks 40inches-and deckman- not seen this one before - just about to start on a 1.8 Mk2 and although this will be my second its always good to
see some different ways of doing the job
I've done this twice to mk1 mx5s. I lifted the uni body up on 4 substantial stack of concrete blocks. Then took the engine and trans out
together. Rear subframe, tank, interior, doors off. I then cut the body up into about 6 pieces (both Rag tops) and took them to the tip in the back
of my pickup.
In summary I removed everything from the uni body rather than removing the uni body from the rest of the car.
