NA6 to NA8

[JMather]

Ok there may be a topic but I couldn't find one. So sorry if there is one.

Oh well it's been discovered that I have the dreaded short nose crank issue! To make matters worse I snaped the bolt head off the crank centre bolt.
So I need a new engine, now I don't want a 1.6 I don't see much of a point (If I'm putting in the effort to put a new engine in I would rather a new, better and faster one.)

So the question is what is interchangeable between a NA6 and the NA8 (head alternator a/c exhaust manifold etc. And will I need a new ecu? Or could mine do it?

Is ther much diffrence between in stock peformance between the two?

Also where is a good place to get a 1.8?

Thanks to any and all who help.

Ps: sorry bout the spelling I'm buggered at the moment.

It's quite an easy conversion...Flyin Miata do a kit so you don't have to change computer and stuff...

Best if you call MX5mania as they have done this many times.

Hey mate

It can be done but everything runs off 1.6 electronics.

To update to 1.8 electronics 70% of the wiring has to be changed as the 1.8 uses different sensors and coils to the 1.6

PM me if you want any more info.

Personally I would go with another 1.6
