Wooooah..NICE!!!
Sadly won't pass an SVA - no mudguards
yeah i seen that around , its not really mid engined tho either , i thought about that route , but i would prefer a proper mid engine .
you guys might one day come round to the idea that volvo cars , will become a suitable donor
still impressive - and that engine will go to about 700 hp with a decent set of rods/pistons , get rid of the pesky twin turbos etc .

Your right about the Volvo engines, I was very tempted.
I do think most people stick to the 'regular' engines like Pinto, Zetec, Vauxhalls etc etc, and then spend loads tuning them, when
there's so much power available so cheaply using other engines.
So far I've spent around £1600 on my engine, but that includes new plugs,race oil, filter, clutch, and swanky japanses boost controller, for an
engine and gearbox that's just 5 years old with 50k of fully dealer service history on the clock. It will be around 260-280bhp of unstressed
reliable Jap power without having to do anything to the inside of the engine at all. I think you would be very hard pushed to get that kind of power
to £ ratio from one of the 'regular' engines.

When are you estimating finishing your car jasper? Can't wait for a trip out!!!!
It's all going very well, but will grind to a halt once the building work starts at Christmas, then I've got a kitchen to build and most of the ground floor to decorate before I can start on the car again. If I get it finished by the end of the summer I'll be happy....
What Nissan engine are you using ?

well heres the bottom end i been working on - custom drilled oil squirters , and 1/2 NPT oil return drain from the turbo

thats supposed to be crinkle coat , i took that after id sprayed it
and if you missed it , this is the effect

well its a transverse engine , not really mid engined - but i know what ya mean
id like to drive it to see how it handled !

yep, mid-engined, same as Elise
hmmm , i have a doubting thomas , at the back of my head concerning mid engine , and rear engine , which most of those are .

I'll disagree with both of you here
Mid engined merely means having the engine between the axles. Aston Martin are quite happy with this definition as well, and they classify the V8
Vantage as being front/mid engined. Elises et al are still mid engined - no doubt about it.
I don't see what's tricky about all of this.....
I have to agree with Volvosport on this one. Elise et al are rear engined as far as I'm concerned.
I was a doubting thomas until we built the mid engined (transverse engine just in front of the rear axle line) rally car (vauxhall nova featured in
ccc mag a few years ago)
The weight balance was spot on, 50 something % rear, 40 something front (54/46 I think???)
It handled extremely well once we finished developing it, but then it's driver seemed to like going off in it and rolling it so reprepping it got
a bit tedious!

Incidentally again!
Transverse rear engined is the same layout but with the centre of mass of the engine placed behind the rear axle line.
Many autograssers use this layout, it makes for awesome traction off the startline, awesome wheelies out of every corner, and with a locked diff,
impossible steering in the pits!!!
I looked last year at doing this by machining the casing on a Vauxhall FWD gearbox, and removing the diff. Replace the pinion on the end of the
layshaft (which normally drives the crownwheel direct so opposite rotation direction) with a borg-warner silent chain sprocket, and then silent chain
drive a spool "diff".
That way you can turn the engine around, place it transversely behind the axle line and still have the rotation the right way!!
Too much work though and rule changes were mooted regarding centres of mass and wheelies!

I don't think there is a proper definition for this.....
For me they mean:-
front engined is engine in front of driver no exceptions.
Rear engine is engine behind or between rear wheels.
Mid engine is behind driver but in front of rear wheels.
Regarding cars with engine in front of driver and also behind the front wheels..... well if these are re-classified as mid engined then almost all
Locosts would surelly become mid engined car.
My R1 powered indy has its engine miles behind the front wheels!
And almost every dedicated drag car or even race car ever conceived would be classed as mid engined!!!!
I think we need to look at motorsport rule books to get a real definition.
no we don't, they have the same arguments!!!!!!!!!
see my posts further up, these are based on motorsport experience and scrutineering opinons..................................we had lots of
discussions regarding various cars that I have been involved with/built.
hmmm , good arguments all round .
the msa book doesnt specify what those terms are , and if you build a single seater , you can put the engine where you like , unless it specifys
distances from axles relative to safety .
i dont suppose it matters whereabouts the engine is as long as thats taken into consideration in design .
Anyway , a TRUE mid engined car has the engine north south
And it has significant effects on gyration , a la 205t16 , until the changed the rotation of the crank .
so dont go yumping in an elise !!!
of course the lambo muira is another exception
Spose that rules out a Ferrari Dino then? The ultimate 'rear' engined car? Doesn't bode well for a Lancia Stratos either 
i think when i say this , its because of the glut of so called MID engine specials that arrived - using the engine and gearbox from a wrong wheel
drive car , and then calling them authoritavely MID engined .
Im sure those layouts did have the engine a respectable amount in front of the rear axle .
The first motor to really pester me with this notion was the MGF .
I think the notion is ok.
The 205 T16 was a bit more tricky as it was 4wd too so had more rotational inertia in the same axis, i..e 4 driven wheels.
I won't pretend to understand how this affected the car but it certainly did!
Certainly our nova suffered no yumping probs, as long as it's driver didn't decide to go off roading in the middle of rallies!
I don't understand why this old chestnut keeps sticking its ugly head up.
Front-engined means the engine is at the front - in front of the front axle.
Rear-engined means the engine is at the rear - behind the rear axle.
So it naturally follows that mid-engined means the engine is placed amidships - between the front and rear axles (if it's the other side of one
of the axles, then it would be front or rear-engined).
If you want to be really pedantic, like Aston Martin, then you could further describe an engine placed close to the rear of the front axle as front
mid- mounted.
It's a no-brainer. Now get back to building cars you lot!
Having been an instructor in a "mid-engined" Ariel Atom for track-day drivers i can quite assure you that the car was VERY tail happy,
catching out all and sundry with it's waywardness (novices and experienced racers alike). It didn't help that it hadn't been set-up
properly, but even when we improved it, it still wanted to swap ends.
Too much weight over the rear wheels, you see... (Honda VTEC FWD engine + trans...) so it was definitely REAR engined.
in total agreement steve!!!!
