I am going to put a Honda s2000 engine gearbox and diff into my mk1 and I was wondering if anyone else out there had already done it? Just thinking of any technical info that would help me along my way
Cheers

Search for owenwilliams. He's done it. His build thread is on miataturbo.net
If you want to preserve the steering rack location - which you should- it's not an easy job.

Be great when done. Always been told the f20 is a tall engine for a four pot so not the easiest to find clearance for, interested to see what work it involves. I had an S2000 briefly....the engine is very special, would love one in my mk3, something about mega high revs and natural aspiration that is so satisfying.
I bought a Cat B S2000 the other year, with the intentions of doing this. And as slow mentioned Owen has one in the UK, i believe it cost near 20k to complete, however he does know how to spend his money! (Motorsport Specialist completed it)
You will have too move the rack (which to me seems totally wrong!), or cut the bulkhead (IVA territory)....I was going to go dry sump to improve things (and s2000's suffer from oil starvation on track) and IRTB's. But in the end i thought... nah life's to short, and if you ask owen whether it was worth the money/agro i got the impression he wishes he hadn't bothered.
In principle totally awesome, but just a lightly boosted 1.6 is nearly there anyway. Just Buy an S2000, great car....still look lovely too.
I'll find my 'failed' attempt thread in members rides...F20C something or other.

IVA territory?
What is the whole dry sump thing about?
IRTB's?
Please explain if you have the time
Cheers
I dont mean to sound harsh but if you're asking those sorts of questions, this isn't a project you should be taking on.
Individual vehicle approval - if the work to the car is significant i.e. chassis alterations from modifying the bulkhead to accommodate the F20 then it will need an IVA before it can be returned to the road. basically a detailed check over to ensure it is safe and meets legislation etc.
The dry sump is because the standard sump would otherwise foul on the subframe, so you'd need to custom fab a sump to alter from front to rear I believe is the issue.
IRTB - Individual Runner Throttle Bodies. or just throttle bodies.
You need to look at the build threads in clubroadster to see how hard these actually are to do.. If you are not a pro mechanic, i wouldnt bother. Its harder than a v6 conversion due to the steering rack I beleive as the Honda engine is really tall.

Proudy202 was doing the same conversion as i bought all his unwanted mx5 stuff off him
that was around a couple of years ago & yes there was a big hole in the bulkhead
no idea if it got finished it or not

If I was gonna go for the time and expense in fitting in a different engine into a 5 I would use one that would make the car dramaticly different animal im talking v8s here.
When with minimal work you can get the standard engine up to 200bhp with a turbo or supercharger kit. Or spend twice that putting in an engine that produces roughly the same power that seems madness to me.
The americans have it the right idea with the monster miatas 400bhp in a small rwd car now that is what I would spend the money on doing not putting in a k20 engine out of a s2000 which if im honest don't find nice to drive into a mx5.
Also if your asking questions like whats iva/ dry sump then should you really be thinking about a whole engine swap.

I can take the criticism or abuse no matter how harsh it is don't worry. Say it straight and to the point... I may not know all the technical jargon but I know the basic ways in and around an engine bay.
Done a few engine conversions before on mates cars but they where pretty straight forward with not much or no cutting and welding needed. I might let one of them know about the iva side of things as we cut out his gearbox tunnel and made it a bit bigger to accommodate the new gearbox. Adjusting the sump wasn't to bad as we had all the info on this wonderful creation that's called "google".
But how ever If you knew how long it took to change websites to first load google, then your search and then load up the site you need to look at when your on a boat in the middle of the red sea with the shitest connection possible you would run the risk of making your self out to be a bit of a Twat rather than waiting till next year for it via Google
Well after avin a pep over jilbobagins start and all the use full info I found on there and owen williams input it does seam like an awful headache. I have been tempted with a few other Ideas but I thought this would be a good one.
Originally I was going to put a 200sx lump in but there reliability is not what you would call great. I did toy with the v8 idea but never really looked into it that much.
The problem with the V8 idea is that LSx engines aren't particularly common - or cheap - over here. And other than them, there's not really many worth considering. BMW V8s from the E39s, perhaps?
The 2.5 KL V6 from a Mazda 6/Ford Probe is a cracking engine, cheap to buy and lighter than the MX5 stock engine, shorter too. You can buy a subframe ready to go and all the adaptor plates/bits you need from Crapengineering on here. Find a Jap import one and it'll have 190bhp.
It sounds fantastic and feels like Mazda should have done it themselves to drive, really suits the car.
No hacking bulkheads, dry sumping or IVA required..

Hi fella, if you've the time then go for it! I would have loved to completed it, but a tasty turbo lump came up and I took the easier option.
Check out miata turbos conversion threads including Owens (which you may already have) ps I wouldn't ask and questions over there, some proper grumpy arseholes.
Good luck with it!

Well I would love to do it but it seams a lot easier and cheaper to buy a 1.8 motor and bolt a big turbo to the side of it.
when I get back to the uk and have a reliable fast Internet connection I will have a proper going over it all and sus out what's what. Cheers anyhow
if you have a 1.6, you may as well just bolt the turbo to the side of that...far less hassle, just up the boost a bit
