Mazda 323 turbo engine in MX5
Discussion
I remember reading somewhere that the engine in the early MX5s is the same as the Mazda 323 1.6 turbo,
without the turbo of course.
Now the Mrs has got a 1996 1.6 MX5 and she wants a bit more poke.
(insert nob gag here)
So instead of paying out for a HKS or similar turbo kit at circa to 2,000 quid.
Could the engine from a 323 turbo be transplanted?
Or could the turbo and manifold and other bits be taken off a 323 and fitted to the MX5?
Anyone with any knowledge about this?

What you need is a man with both
An MX5 & a 323 Turbo & a spare engine in bits....
Right the block is the same, the head is similar, but difference is mainley the the 323 has a clockwork dizzy & the turbo points downwards on the 323 and I think the chassis needs cutting to fit it. Then of course there is the plumbing issue.
Apart from that the 323 has 7:1 compression ratio with the right turbo means heaps of power. Plus the rods are far stronger than the 5 ones.
The MX5 head is very similar & bolts straight onto the 323 head.
So if you'd like a complete engine in bits suitable for 280+ bhp I have one here.

Of course, you could just buy the Greddy MX5 turbo kit for £950 and save yourself a lot of hassle! The same sort of power increase as the HKS kit but a wee bit cheaper - the only trouble is its not very upgradable if you get the power bug and want to go further.
There were a few thread along these lines on the MX5 OC forum a while back, and the basic conclusion was that you'd have to get a manifold made up and a lot of custom pipework, and it'd be easier to buy an off-the-shelf kit that was actually developed for the MX5.
Along similar lines, i noticed that the Eaton supercharger used in the Cooper S is the same series as the one they use in the Jackson Racing supercharger kit for the MX5. You can pick up the SC on ebay pretty cheaply and I was hoping to adapt it to the MX5. Again it turned out that it'd require a LOT of custom work (mounting brackets, outlet manifolds etc) and would work out much most cost effective to buy a ready made package.
