would this engine fit in....

[GTRene]

I was wondering

will such 340hp Audi 2.5 TFSI R5 fit in a Lotus Elise/Exige?
the sound is nice too.



It looks not that big and has easy power...

It is originally in cars like the Audi TT RS, thats AWD so I don't know if you can use the gearbox to?

this is how it sits in a TT RS





just curious

[Scuffers]

doubt it

inline 5 is going to be at least 80+ mm longer than the inline 4, and the Audi 2L engine is a close fit.

why do you keep coming up with these 'great' engine idea's?

if you so obsessed with the idea, how about you go to the trouble of actually learning what's required, then trying it, rather than keep on posting threads about this or that engine?

[cyberface]

Unnecessarily harsh reply Simon unless he's been harassing you with requests for engine conversions for ages - he didn't mention the word 'great' in his post either.

There's a fair amount of pent-up demand for an Elise with a better sounding engine than an inline four... but as we've all done to death, there's nothing out there sensible that fits. Perhaps, soon, some manufacturer *will* announce an engine that *will* fit and will sound great and have decent power... my money's on a boosted triple though rather than *more* than four cylinders, purely because if you're going to increase efficiency / power / reduce emissions by adding loads of ancillaries (turbos, superchargers, manifolding, etc.) then you'll need a smaller block to begin with.

But I haven't heard of any 200+ bhp triples out there Would sound nice though.

Then again, I suppose Lotus could try the Ferrari computer-game approach instead, and fit a few strategically located high-power speakers (bear with me) that cancel the engine sound from the boring old four-pot, and overlay whatever engine note you fancy. BRM V16 one day, hot A-series with LCB zorst and a cherry bomb the next

Why? because I don't know thats why I ask and the engine looks good...and you and others know more about Elise/Exige then me, thats why, so now you know
Also some people could be already into it, I was just wondering, I hope thats not a problem for you mister Simon

Thanks for your thoughts though.

Because he has an imagination. Without it we would still be using square wheels.

point and missed...

if he had imagination, he would actually have done something about it....

Give it a couple of years for BMW to sort out their new line of 3 pot motors. They seem to have cracked the secret of playing the emissions game. Not sure what a turbocharged and Supercharged 1.5 tripple would sound like though.

Some people are doers and some people are thinkers. Most thinkers aren't doers but most doers are also thinkers. I think.

Much like a 6.

The Camry V6 will fit if you want more cylinders. It fits in the mk3 MR2 that has the stock S2 toyota engine with little more than a mount kit thats available from twobrutal.

[Esprit]

There's at least one VAG VR6 engined one floating around out there too, although you do lose pretty much the entire boot with it and it looks like it extends a fair way back, which must give it 911 levels of rear weight.

I believe there's someone doing conversions now but I think it takes the entire boot away. No idea about the effect on handling.

I've seen that one, also in Germany was/is a VR6 engined Elise a few years? ago, then maybe the R36 would fit also...but I have no idea.
That 2.5 TFSI 5 cyl is not that wide, only a bit longer, anyway just a thought and wondering would it fit, some conversions have some space left, but I don't know how it then could fit with the gearbox etc, I'm not a builder, just a enthusiast.

could be interesting too, I've heard about MR2 with such conversion now you mentioned it never seen a Lotus with that though.

this is exactly why this kind of thread winds me up, total ignorance of the subject combined with some half-baked information somebody read somewhere on the web.

an I-5 engine is going to be LONGER than an I-4, as in 1 cylinder width longer at the very least.

the current Honda/Audi engines that are used only JUST fit, as in we are down to the last few mm of clearance, so unless you have an engine and gearbox combo that are the same or shorter, forget it.

Toyota engined cars have a bit more room to play with, but still not enough for a I-5 unless the gearbox was very short.

V6 engines are usually shorter than I-4's, hence why it's not impossible to fit one, although they are somewhat bigger the other way which has another set of problems, so you end up with them being very high up in the car (not a good thing).

Now, without being silly, that's it, no Volvo/Audi/Ford 5 cylinder engines, no i-6 enines, etc etc etc.

unless you want to spend a small fortune on re-designing the back of the car to take a transaxle etc, then it's just not going to happen, and even if you did, it's not really an Elise any more is it?

Rene,

HOW MANY MORE TIMES ARE YOU GOING TO START THREADS LIKE THIS?

[GTRene]

Thanks Simon, only that last line was not necessarily...

and, you don't have to read or answer it, you can.

[GTRene]

came across this pdf, there are the different R5 engine's explained in lengt, see page 4.1

the R5 250kw (wich I ask for) is on that diagram? 494mm wide...while the R5 for the Volvo/Ford is 591mm so there is a different in wide-nes? also more info.

wich is indeed as S says about 75mm longer then the 2.0 TFSI R4.

Which I guess is where the VR6 design wins some points with it not being much longer than an I4 and only slightly fatter top end. Also they have all the ports on one side only not being a true wider angle V6 (i.e. exhaust only coming out one side) which must help when using it as a conversion with ltd space.

exactly, although it does end up somewhat high up in the engine bay... (and it's a dam heavy cast iron lump!)

here you go - a car already done for you with VW 300bhp 3.2V6 ...and pretty reasonable price too
