MK Sportscars - F20 vs K20

[Rob Hunter - Club Secretary]

I quite enjoy trawling YouTube looking at the various kit car videos and I started to subscribe to MK recently. It's interesting to see the similarities and differences in engineering solutions between our Westfields and their Indy's.

 

Generally the Indy now seems to mostly run mx5 (n/a or turbo) or bike engines, but a few are running the S2000.

 

Next week they are doing a weight comparison on the F20 on standard gearbox with a K20 on a MX5 6spd (with new adapter plate) that some might find interesting. The mazda 'box is definitely a lot slimmer up to the bellhousing but I'm not sure how they are solving the height challenge with the K20...

 

At the end of this week's you can see the two boxes side by side.

That sounds interesting but no doubt will continue to fuel the people who've not fitted a K20 into a kit, to continue posting fit a K20 as they're cheap and can be cheaply tuner to billions of horsepower etc.

 

This usually arrives on any S2000/F20 threads on FB, not so much on here, luckily!

 

Great if you've fitted one and can tell us how it fits (I'm not including a certain lovely, well engineered speed series car in this, though) and what the ground clearance is like for road use etc.

Apologies, that's part of why I buried it here rather than in tech talk! 🤣🤣

 

I had an inner battle with the voices of reason 🤦‍♂️

No need to be sorry! It's all very interesting! I'll like the guys accent and enthusiasm too! I just keep waiting for him to say 'Only me', as Harry Enfield did! Also, interesting that they're using the 630ECU, I 'thought' that was Westfield only supply?

[Rob Hunter - Club Secretary]

Haha, he reminds me of Gregg Wallace from Masterchef 😂

 

I did agonise over posting it, but it's the first time I've seen a kit manufacturer seriously look at a RWD K20 solution.

 

Maybe the MK has an deceivingly tall engine bay?

I suspect he'll dry sump it! Given the rarity of F20's, those of us with F20's may one day need a replacement and hence a K20 may be the route to go.

Im seriously considering picking up a K20 at some point and seeing if I can create an adaptor from my pile of F20 gearboxes. The cost of mapping/dry dumping etc is a put off but maybe a build over a few years could take the pain out of it????

Have you got room for all these 'trinkets'?

Sounds painful 😉

You can say that again! You'll end up needing a new ring gear for your rear end.

I've  a pal that's fitted a K20 into a Caterham.. it was a squeeze, and he had to dry sump it to get it under the bonnet. He's using a Caterham six speed box, via an adaptor. (Same fitting as a Ford type nine, so a beefed up type nine would maybe do the job?)

I see you're located at Warrington? .. you have TDI north on your doorstep,  for any specialist tuning /mapping. I've dragged my son's race CRX down there a fair number of times for mapping.. they're good lads.

That’s basically it, it will keep me out of mischief. With F20 prices as they are it’s probably about the same all in as a straight engine swap. Who knows it may never happen. But as soon as one person gets it to work then it becomes an option for others.
 

I would probably end up building a new car rather than messing with the hoonicorn so it’s a long way off yet.

Those fb f20 vs k20 battles always do make me chuckle. You never seem to get zetec vs duratec kick offs in the same manner . Just seems odd kicking off over 2 very good engines. 

 

I looked into the k20 a few years ago when I decided that I couldnt stomach the cost of an f20. From my rudimentary measuring of my mates ep3 I reckoned with the v8 bonnet it was just about do-able without dry sumping. 

 

I am surprised that no one has seriously gone after the k20, it seems to be the perfect engine for our cars. NA, the 200bhp figure that most end up going after, reliable, responds well to tuning and boosting aswell. And generally a third of the price of its big brother.

A few have started, but in the world of the Forum, pretty much all have been either sold as incomplete projects, or broken and the K20 elements sold off individually. To the bes of my knowledge, @Delboy car is the only successful conversion running, amongst WSCC members, (at least ones we see or hear about on the forum). And Del's is such an extreme example in terms of engineering, spec, and bespoke/semi-bespoke parts, that it almost may as well be a McLaren engine swap for most of comparison details!

 

I guess there probably are Westfield's out there that have been done, in the way that there Westfield's out there that have had what increasingly feels like some of the near mythical Mazda gearbox swaps. They're just not in Club circles!
