Elise engine conversion: Honda v Duratec

If going Honda, do most people not bother about changing the clocks? Rev counter only goes to 8k...
I have toyota clocks to use although they have a CAN-bus interface so a small embedded system is required to sit in the middle. IIRC Hondata can supply a box of tricks to do the same. Scuffers said:

120kg must be without ancillaries and gearbox.
As above. The Honda K20A2 is around 40kg more than the Rover K 1.8 in the same state.
The reason I measured it was becuase I was sick of reading all the bullst.
with ancillaries, no gearbox.As above. The Honda K20A2 is around 40kg more than the Rover K 1.8 in the same state.

Gearbox is something like 41Kg's
engine holds just over 5L of oil, gearbox is under 2L
Next problem is your average weighbridge is calibrated to ~20Kg's at best for objects weighing several tonnes, not a light car.
Not saying yours is not that heavy, just that they don's have to be.

I must be the only person in the world who doesn't like the power delivery from the Honda engine, it just felt a bit gutless to me until the very upper reaches of the rev range, by which point the car sounded like a bandsaw, not a car.
In the end I went for an Elise with a DVA head and ITBs, nice, reliable 180bhp, sounds great. Still a very linear power delivery but a good slug of torque in the midrange.
I think there are some good points to keeping the standard engine but not sure I can understand this. 180bhp Rover K dyno is here:In the end I went for an Elise with a DVA head and ITBs, nice, reliable 180bhp, sounds great.

Even a stock K20A2 has slightly more torque, as you would expect with 200cc extra capacity.

I have to agree. I know it is fashionable to love VTEC, but I don't.In the end I went for an Elise with a DVA head and ITBs, nice, reliable 180bhp, sounds great. Still a very linear power delivery but a good slug of torque in the midrange.

I built a pretty cooking 2l K20 a couple of months back with some hot cams that does 140lb ft at 2000rpm, peaks at 178lb ft and does 250hp at 8200rpm. I think if you find a K20 elise gutless you're not driving the right ones.
I must admit, I've never driven a k20 Elise.I was never a fan of that engine in a Civic though. I much preferred the H22A I had in my Prelude!

It feels very different in a car which is half a tonne lighter. I was never a fan of that engine in a Civic though...
As someone pointed out above, the K20 has a fair chunk more torque than any K-series or naturally aspirated Toyota engine they put in the Elise.

Yeah, I can imagine!As someone pointed out above, the K20 has a fair chunk more torque than any K-series or naturally aspirated Toyota engine they put in the Elise.
It’s a toss-up between the K20 or Duratec for me.
K20 would cost a fair bit more, but re-sale is somewhat higher.
The car feels like a keeper though.

In which case I strongly recommend you drive a good example of each, as they're entirely different beasts. It’s a toss-up between the K20 or Duratec for me.

besides the power, the K20 makes driving a Elise an event. The sound and the slick close ratio gearbox alone are worth the trouble.
a Duratec can be as fast, but it won't "feel" like a Honda ragged to 8000 rpm though the gears.
To use Dan as an Example. Would you prefer this

The Duractec sound like a powerful Rover K. I like it, but it is not as rev happy or has a as wide power band as a Honda with its VTEC.
Both cooking cars BTW :-)
I'd try both before committing.

The main concern for me about the K20, is that I’ve read a few times that is has spoilt the handling balance of the car?
That would be a big problem for me, as the handling is what impresses me the most!
I’m not sure I could tell with my meagre ability, but I don’t want to make it any more snappy!
I will try and drive both before I make the decision, easier said than done though, both are quite rare beasts.

Hello All,
My first post on here so go easy on me please :-) I am the owner of the blue Elise S1 that is shown in Will_S 's Honda conversion thread. I have just ordered a Stark kit but I have a bit of a dilema. I have an EP3 for a doner but in my shed I also have a K20/K24 Frankenstein engine which i intended to go into the EP3. I don't know whether to put the K20 or the K20/K24 engine in the Elise. Anyone have any thoughts, opinions, etc ?
Dave.
