so then - no k20z in the back of an elise then. one wonders what may happen when HOnda stop supplying the engine in the uk, if maybe people will see it as a more viable option on the basis that eventually there will be a type r with a different engine complkiant with current emissions regs. so people will start being more careless with their FN2's

??

not sure what your getting at?

there are a couple of mine running about with K20Z's on them, it's just not mainstream yet, although it's heading that way.

right you are Mr Scuffham. So are these custoemr cars which have them in doing developement work at the moment, and what is the comparative cost? Did you manage to get the various issues sorted with as much aease as you had in fitting the K20A into the same cars, or was it significantly mork irksome?

For that matter the cars that do have them in, are they S1 S2, toyota or rover based donors??

they are 'tame' customers cars that wanted to try these.

both are S2 Elises, but are not 100% what will be the std install, (and there are differences between them).

the real work is in the electronics for them, with things like specing an ECU that can do DBW as well as everything else in a road car environment (every ECU maker says they can do DBW, but very few of them will actually deliver for road car use (ie, they have not homologated solutions that can get insured).

there's about another 3 months work on this aspect for the K20Z engines use in mainstream installs, but this is very much the last leg of a lot of work.

well thankyou indeed then - so will the honda elise website be all updated with details of install costs once the development is complete then? I love looking on that site, it's like my playboy - never much new material but always something to dribble over!

Are these common-place now?

[Jodele]

Define common... I'd be very surprised if there were 200 Honda powered Elise/Exige/211 globally.
Back then, it was thought that the Yamaha engine was not that durable...and that has been proven wrong too. So, there was no real need to go to Honda power...

Once you've had a Honda, you won't give the Yota a second look.

[Lefty]

I was meaning the k20z as opposed the cable-throttle a2 - and not necessarily in a Toyota engines Elise.

It's getting hard to find decent second hand ep3 engines...

[kambites]

This may be a really daft question but can you install a K20A's throttle body on a K20Z and then use an after-market ECU to drive the whole thing with a cable throttle? I don't really know how different the two engines are.

[Lefty]

Well that's exactly what I was thinking too.

Yes - thats exactly what i've done several times.

[Lefty]

Interesting.

Are there any other differences between the engines?
