Search Performance Forums for more on the above linked car - KP60 something Starlet with a Hayabusa motor!

Nice thinking with using the std 4 spd as a reversing box, also shift a bit of weight to the rear..

There are some nice conversions out there

Sykine the Volvo rear end would need the De Dion tube modded to
suit a fwd like setup on the rear or if room allowed as you
say north south but on the back seat and just a short tailshaft
to the fixed diff and cv joints.

how about using a modified transfer case for the reverse and
a starter motor on the auxilary?

aussie race cars actually run fj1200's putting out about 125hp but yeh, they hammer! there is no better feeling than accelerating sideways around a corner, backing off for a tenth of a second, pulling the next gear and keeping it hauling arse around the corner

The winner of the top X prize 100+ mpg competition 5 million dollar purse
went to a 400kg 2 seater with a supercharged 380cc bike engine.

If I could weld up the doors, chop the roof off and strengthen the chassis
of my 1000 tudor with a twin hoop bar and run a 600cc bike engine with lil
SCharger then I could have a 80mpg sub 500kg B10 that spins to 17000 rpm.

eg.
minus engine/box/radiator/fluids/exhaust/battery/bumpers 625 - 150kg = 475kg
tube chassis strengthening and twin hoop 475 + 80 = 555kg
minus roof/ windscreen/door mechanism and gutted/h145 diff/tailshaft 550kg - 80kg = 475kg
minus front leaf springs and add coilovers 460kg
600cc bike setup at the rear with volvo modded single leaves minus stock springs,
custom de dion tube, shortened driveshafts, shockers and hubs + 60kg = 510kg
further lightening using hole and stamping -10kg
disc brakes all round instead of drums -5kg
Boot area shortened and modded for fibreglass see-through fluted back lid -10kg
Tilt front setup with alloy foam filled fuel cell -5kg
Magnesium rims and lightweight seats equal weight
no back seat -2kg
Final target should be below 490kg so with 90hp NA should be nice but boosted
to 130hp with small supercharger will be lovely equal to 250hp per tonne.
Go crazy with hayabusa setup and go up another 40kg and will be lethal.

just buy the bike... or build a formula SAE car...

this car is hardly going to be a street car anyway, so why bother keeping it a car at all

doesn't make sense at all to me, if a motor is designed to push 200kg why would you put it in something that will weigh 600-1000kg (weights including rider/driver)

surely it would for one; be a pig to drive and for two; as mentioned the engine will not last

the other side of the coin.... say you are aiming for the ideal 50/50 weight split or slightly heavier in the front 52/48... dropping all the weight out of the front end is going to push you into 45/55, heavier rear end... therefore potentially negating the handling benefits of loosing the weight?

surely the same people that understand that comparing maximum HP figures from a dyno means very little on a race track; arn't the same people being lured by high HP figures from motorbike engines designed for crotch rockets?

just spent a while you tube'n some cars with bike motors, they are all in very small cars usually with perspex windows and other extreme weight loss programs, and they all seem to love doing wheelspin/donuts... in fact none of them look very fast, they are loud and chew through gears quickly so they sound very fast.

None of them seem to be able to get the things high in the revs without wheelspin, and of course when the wheels are spinning there is minimal load on the motor which is allowing the high revs

well said rallycar, totally agree

imo i think your under estimating them a fair bit, i think a boosted hayabusa engine would go nicely in a 1000 with a bit of weight reduction.

I think a lot of the conversions into full size cars are biased towards offroad so as to not stress the clutch/transmission.

The motors won't be a problem, late model bikes can do big K's no problems, it is the tranny/clutch that is affected by the extra weight a car carries.
My bike has done 50k in 4 years, no problems whatever, this is a 140hp motor that rev's to 9.5k and sits at 4.5k on the freeway all day long..

Depends what you are after, its good to think outside the square
and see if there are any other options or possibilities.

Even the Escort with 900c turbo has the following Performance
0-100Km/h - 5,2 Sec.
0-402m - 13,8Sec.
That is fast for a heavier car than a 1200 or 1000, there are
95% plus 1200s that struggle to get that perf with an A series.

the above link interests me for another angle which I made a
mistake about and uses 250cc supercharged engine with 370kg
final weight and a huge 40hp :)
Well it still has performance better than most cheap hatches.

Its like when I first owned an mx5 back in 89, It only had a 1.6
that is lame by performance standards but the car felt sporty,
sounded good and handled great.

I also owned a honda z600 that spun to 10,000rpm and although
I was only doing like 60kmh at that rpm in 2nd it was fun
A sports car can be different things for different people.
