Hi All, got a noob question for all you lotii experts!

obviously reading these forums and seloc i see all types of engines going into the Elise, Honda K20A2, Ford Duratech, T series etc etc.

Seems like the above Renault sport engine would/should also be a transplant candidate. High revving, i'm assuming its lightweight, Tuned by Mecachrome (of F1 Fame, current V8 in the F1 'lotus', all the GP2 cars), has proven to be reliable and is easily tunable via remaps* and a plethora of off the shelf parts.

its that flexible its sprouted a turbo and powers the GP3 cars, they're tiny!

Another bonus i see is that the donor car is cheap, has a propensity to find its way into ditches due to its core audience.

oh and they sound a bit good as well** All pops and bangs.


what am i missing?

(apologies in advance if this is a stupid question)

I'm sure it'd be possible. I suppose the question is "what would it do better than the K20?".
Indeed, i'm thinking it would be lighter and possibly cheaper. After looking at both K20's and the Renault engine it also looks a deal Smaller.

Thanks for the replies chaps, I understand it's not just a case of winching it in and praying it works, more a case of why it hasn't been considerd in the past.

In my eyes it's certainly a match for the n/a dura tech lumps and i would stick my neck out and say with a bit of fettling it would be a match for the Honda unit. Taking into account it's smaller (not sure of the weights)

Food for thought anyway plus lotus Renault has a good ring to it!

There is your answer: compare a known and proven conversion with masses of tuning potential and several turnkey options out there to a new one-off, with a largely unknown amount of effort to a) make it work and b) fettle it further in order that it would "match" the first option. I know which I would choose.
Well they both pop out at 200 Bhp, the Renault sport engine actually has a higher torque figure out the box 159ft lb for the rs engine at 5400 plays 142ft lb at 5600 for the Honda unit. With that in mind the rs engine is actually better out of the box so maybe I was a little harsh saying it needed fettling.

The rs engine has lots of turn key power solutions aswell, plus I'd be interested in a weight comparison.....not to mention price comparison

I think what it boils down to is the dev time has already been ploughed into the Honda Elise, why fix it if it ain't broken eh?
