So the gearbox is fixing... then this happens...
Discussion
Seems my troubles are far from over. Having destroyed the gearbox with some airbourne action I finally get around to having it fixed, only to destroy the engine.
Long story short, at the end of a 200mi journey theres a slight knocking from the engine. I figure its eaten a bit of oil, as it does, and go to top it up only to find the sump is next to full. Progressively the knocking worsens; one crankshaft bites the dust would be my best guess, can't see what else it could be.
So Saturday was spent driving to Marlow to collect the can with a rented flatbed before returning it to Bury, a good 15 hours of driving the s
ttest transit flatbed imaginable.
So all in all a poor month for me. One new XJ8 being fitted, and one dead MX5 engine needing replacement.

Not sure I'd trust an £80 eBay special to be honest. Besides, the cost is in the labour and mapping not the engine.
Assuming I go with another MX5 engine...

Then again, the noise...

Crappy news Chris. Ive always pondered what I'd do if (when?) mine goes bang. I was thinking an mx5 engine with forged internals, but cant help think an SR20DET would be more reliable...
A five engine with internals seems the most logical choice, but must admit, I'd like something with a little more character. Hadn't considering the SR20; are they an easy fit? I believe that 300BHP is attainable on standard innards?Currently leading the fantasy list for its next powerplant is a 13B turbo. There's a few in existence and they're very powerful, but I'm not certain how much work's involved. Then again, my garage of choice is an RX7 specialist with 20years of experience, so if anyone can make it happen...

Good for over 300bhp on standard, a friend of mine was running 380 reliably in his S14...

Its been done a lot in the US IIRC. There are some uk guys too, a couple on nutz i think?

Any idea how easy the conversion is? Both longitudinal 4 pots, so I'm guessing it could be easy?Good for over 300bhp on standard, a friend of mine was running 380 reliably in his S14...

Conversion looks quite tidy, very similar looking to the standard engine just a bit bigger. Disgusting paint job though, and can't help thinking he might be living on cloud cuckoo land thinking it's worth £6k... but you never know. Suppose it's still cheaper than doing it all from scratch.Keep the ideas flowing... and I'll get selling s
t at the new job to fund this madness.

I don't think it's any easier than any other engine conversion. There's a mahoosive thread on miataturbo.net with the conversion, didn't look simple to me.RE the LS swap, the LS doesn't actually weight much more than the stock BP engine in a 5, that's Alui blocks compared to cast iron for you. Handling isn't really effected.
