Hi All
Say I wanted to put a bike engine in a small car, behind the occupants, much like ZCars do all the time.
I'd like an enclosed car (be it soft top or coupe), therefore with a windscreen, so cars like the Sylva Riot or J15 are not suitable.
It looks then like a proven solution like the ZCars Mini line-up or similar conversion would be ideal.
However, I've recently found out that the Mini Marcos curb weight is a mere 476 kg (source Wikipedia), which is great given the relatively modest
torque of bike engines. And there's also the Fiat 500, which weighs 499 kg as standard.
So, would those two suit at all? Any other alternatives? Thoughts?
Scootz has a smart roadster that would fit the bill for sale.
reliant kitten. my mate unijacko67 is doing a honda s2000 powered one but a rear engined chain driven one should be possible.or a front engined prop driven if you wish.
Smart roadster would be brilliant!
Those z-car minis handle like a bag of sh*t..
Smarts are WAY too heavy for me (the Fortwo is 730 kg and the Roadster is 840 kg). The Reliant looks pretty interesting at 508 kg, in fact:

T66 has his Fiat 126 http://www.locostbuilders.co.uk/viewthread.php?tid=148837
The biggest problem is probably the extremely short chains you get which causes wear problems.

Nice one.
Actually, now that you mention it, I had seen some 500 on Youtube before.
The 126 was quite heavier, around 100 kg extra, but still reasonable, 580-619 kg, lighter than standard Minis, quoted 617-686 kg.

do you mean the z cars fwd one or the spaceframe rwd one (spins like a top)
if your from spain a nice seat 500/600 should be possible to secure ...........
Hillman imp - imp Paul has a busa one
Reliant kitten - groggy has a Saab turbo one
Scott's Smart on a space frame will be as light as a light thing. Don't dismiss it. A spider style smart, with a bike engine would be very
different.

I'm not convinced by the chain method either, despite it being the preferred solution for the majority of mid bike engined cars including Radicals and so on. I often think about going single seater by putting the engine to the side of the driver, in a Locost configuration (north-south, prop shaft).

No chain in my fiat, far too short wheelbase.
I managed to find a Quaife powertec axle, thank you scootz

i have got an imp they weigh absolutely nothing mine is fully gutted at them moment and i push it around all the time with one leg out the door while steering
How about a GTM??
ash is bang on the money nothing heavy here lol
this is how the shell is with no floor omg
I have a spare kitten van at work and if I was doing another one I would buy a cheap mx5 , simple ladder chassis using both Mazda subframes and use
everything else as the seats fit etc . 1.8 donor would make 130hp 800kg daily driver . The running gear fits under a scooped out mini van with clubman
front so no issue with a reliant body .
Mid engined gives me great traction but no where near as much fun as rwd

Simply hang the Z-cars type frame from a well-bolted-in rear roll bar.
what about a suzuki capaccino thingy.
There was a bonkers one reviewed in PPC about a year ago. It had a busa lump in which is sweet as the manufacture is all the same, good pub banta!

wonder how much an elise would weigh without the K series and gearbox??
All these weights you quote do they include car engine and box?? obviously a bike engine saves a fair chunk of weight, a 5vy R1 complete engine weighs
in at 65kg
If you have already bought the classic mini transfer box it's a bit late, but if you haven't I would suggest you turn your engine the
correct way round and use a jackshaft to a more normal chain driven diff, this will give you more weight forward and too the right, if you want to,
and also let's you use a long chain with plenty of room for an electric reverse aswell
This is the style of jackshaft I bought for a previous project
Cheers
David
Mine is the same track /wheelbase as an Elise and the z cars Monte Carlo is very similar , smaller than that especially track would be hard work to drive on the limit . Mine is just over 800kg but has a good chunk of weight up front
Found an old drawing I did
Cheers

a bog std. pug 106 is about 760kg (s1 4speed) - and it could loose a bit easily enough
or the citroen ax is even lighter (same running gear)
On the subject of the Z cars mini's, why do they handle so badly? I've heard/read it several times, but as has been said they've got a
lot of adjustability built in, surely they can be made to handle well?
On another note, my vote goes with the Busa cappucino!! Great suggestion!

Another vote for the hillman IMP here!
IMHO - I fully anticipate twitchy handling with the Fiat, happy to turn in rapidly but also swift to snap into spinning oversteer at the drop of a
small hat. My car is different, built for fun, thats about it.
Only my own take on why the Zcars are not brilliant on a circuit, but weight distribution is the key here, linked to that , a sensible wheelbase.
Mine has the weight distribution of an old 911, the wheelbase of a Fiat 126, and lots of power hopefully. If I was building a circuit racer, I wouldnt
be where I am, MK Midi / Riot/ seven type of car would be my choice.
BTW - Take a look at your Ultimas front suspension, then look at mine.
I suspect the differences in bodyshell weight are academic , as mine consisted of side panels and roof, it could of easily been an Imp/Mini or Smart
mounted on my chassis. Thank you Nat & Cal....
body panels here you go lads

Which GTM are you referring to, there are several different cars? The GTM Coupe weighs around 610kg with an A series engine and box. The original Cox GTM was weighed at 533kg (with 10 inch steel wheels etc).

As a zcars mini owner I feel the need to defend them when reading comments suggesting they handle like badly.
Autocar published an article & youtube video of their test of one a few weeks ago & described it as having 'unforgiving limit
handling' which my be a fairer description of them & other extreme track biased cars. They also commented they suspected it was capable of
posting lap times comparable with a current 911!
They might be hard work to drive close to the limit but to write them off as being s*?!e handling is unfair on a company who have spent years racing
& developing their product to the degree they have!
O.k rant over, i'm off out to work on the car......please god don't let me put it through a hedge after defending it on here!
Adam.
Here's the autocar review:-
http://www.youtube.com/watch?v=p4ABcXh9KtQ
& some great driving by Tim Schrick if you skip through a bit:-
http://www.youtube.com/watch?v=PT437kWV8Rc
I just had a quick squiz through that vid, so this may be wrong...
The Z-Cars was on slicks and only managed to beat the production mini by a second!?
Michelin P220's according to the mag' article so wet race tires. They reported the zcar broke down before he could set a quick lap hence his
comment about suspecting it would be comparable to a 911. I'm no fan but that new mini is setting the quickest lap times of the modern hot
hatches so no slouch itself.
I'm only hoping to suggest they don't handle as badly as previous comments might indicate, realistically it's not a car for mixing it
with the Radicals etc but they are raced & hillclimbed successfully.
Adam.
I would like to comment on my personal understanding of what good handling is, from my admittedly limited track experience and driving skills.
To me, the concept of handling is related to the behaviour of a car while understeering (front slides), oversteering (rear slides) AND drifting (both
front and rear slide), as well as the transitions (no sliding to sliding and back to no sliding).
Handling is therefore not related to reference lap times (a professional driver will overcome bad handling through driving skills), cornering speed,
or even tendency to under/oversteer. For example, early straight six TVRs such as the Tuscan are known to have poor handling (you may remember J.
Clarkson having a laugh about that on the track), but they are fast around corners, simply because, even though they will spin if they go, they
won't go easily.
So, to me, "unforgiving limit handling" equals bad handling regardless of both lap times comparable to a current 911 and race and hillclimb
success.
How much of that may be true for the ZCars Mini, I'm clueless about, Tim Schrick's review suggests its handling is actually alright, and I
suspect bad reviews may come simply from poor tuning, since obviously, a car with fully adjustable suspension geometry needs a good amount of
attention, expertise and time on the track not needed in less sophisticated solutions. I'm just guessing.
Like I said before I'm not at all into racing (otherwise I would look for a proven solution with good race heritage, like say a Fisher Fury for
example), lap times mean nothing to me, but I do want good handling, because the better a car handles, the easier it is to use it as a tool to improve
your driving skills, and to me that's the most important thing for having fun on a track day. On that respect, I have learnt the most from track
days with my MX-5 mk1 under the rain, despite all my kit cars having been MUCH more exciting and informative in terms of feedback to the driver.
Does that make sense at all?
[Edited on 15/3/13 by Alez]
I would like to add my bit to this as well, I have been to the Z Car factory and was taken out by Chris (a few years ago now) and was more than impressed with the cars ability. In fact we still talk about how well the car handled years later. First class conversion and well done to the man. only reason i did not get one was it was still a mini!! each to his own but not my cup of tea it was absolutley planted FANTASTIC.
I know of a complete super imp that is looking for a new home.
Hasnt been on the road in 11 years but has been stored in an open sided barn.
I have been offered it for free but with a 1976 mini, 21 year old vespa, kitcar to build & a growing family i cant take it on
Engine was started last year too.
Let me know if you might be interested, it was offered to someone else until i found out they planned to just sell it straight on! We just want it to
go to a good home & maybe see it back on the road in one way or another.
my first mid engined setup in the kitten was a tl1000 v twin running on 10"wheels with 165/70/10 tyres . 460kg 120hp and the most fun to drive with plenty of slip angle and no snap oversteer .when i went up to 13" with 50 series tyres it lost all the movement and would push on rather than the rear coming out .

Bought this today as a project, Imp Super/thunder saloon based on March F3 car.. Originally BDA engined with hewland box!
Should keep me busy for a while..
Ooops.- didnt realise you were in Madrid :-)
Thats would be a serious journey just to pick up a car !
Good luck with the search.
