OH god, want!

If this was a readily available conversion in the UK and didn't cost daft amounts (like more than, I dunno, 3k - plucking a figure out of thin air) then I wouldn't half be tempted. Imagine it biggrinhehe

This man speaks sense - Chevy V8 over the Ford any day:

Worth it for the noise alone, bonus points for sleeper value.

Also been done in Aus, IIRC with a Lexus 4.0 Engine and Toyota Supra gearbox. I would love one.

If it's that cheap I could be tempted to buy a Mk1 solely for that purpose...!!

Did I miss something?

I'm seeing ~~ $4000 for the kit, plus the engine?

Surely it would ruin the handling? Why not put a lighter (more modern) engine in instead?

Ah, I did miss that. I was looking at flyin / monster miata websites, which both listed a complete 'kit' at about $3900 / $3800 ish.

There is somebody on youtube who put a V12 in his MX5, I'll have a look now to see if I can find the linky.....

The Chevrolet LSX engine series use alumin(i)um blocks, so even though they are larger than the MX-5's iron block, they don't weigh much more. Combined with a heavier rear diff and beefed-up driveshaft and hind quarters, the weight distribution on most of these V8 conversions remains extremely close to an unmodded '5. So, you end up with a well balanced, 1200kg-ish 400BHP-ish MX5, which I'm sure will be a giggle to drive.

I want.

EDIT: As for modern, the LSX engines are not old American engines based on 50s technology - they were a new design first used in 1997. They might have pushrods, but that allows the camshaft assembly to sit low down for a lower centre of gravity, and the block (as I have said) is aluminium and very light for its size. These engines will also return over 30mpg in Corvettes, so for their size and power output, they are relatively light and economical.

Don't believe everything you hear on Top Gear wink

Oh, and don't even start on leaf springs..........biggrin

So due to the fact that the MX5s weigh.. *works it out*... *carries the 1*... around fk all, the economy when cruising ought to be pretty amazing too? biggrin

Corvette's not exactly lardy. I'd put my finger on the difference in fuel economy being the difference between nothing and sod all. smile

The C5 'vette weighs 1500kg. That's 500-700KG heavier than an MX5. Need I say more? tongue out
