Bike engine?

[stv2100]

Has anyone considered installing a bike engine such as from the Suzuki Hayabusa. I've had a quick search and I can't see any posts suggesting it.
I've been looking at some of the vids on You Tube such as Hayabusa powered smart cars, Golfs, Mk2 escorts etc. Surely it must be possible in the 2.
Future project for Rogue perhaps   s:D s:D  .

would engines like that have enough power to make a big difference to the 2? remember that for under a grand's worth of mods many have got 15-20bhp on top of stock figures. any engine swap is gonna cost upwards of this surely.

unless you count the 2zz which is yamaha built after all  s:wink: :wink: s:wink:

Blackbird engine or hayabusa is damn fast, many of them installed in various cars including my mates mini with one in the front and one in the rear giving 4 wheel  drive, 2.6 litre and 13,000 rpm or something daft!

They fit these engines in Radicals and plenty of kit cars. A 1300 bike engine shouldn't be thought of in terms of similar sized car engines. They are as close to Formula 1 as you will get on the road. There's plenty of power and then some. You can even get a turbo version with 500bhp. Look at the bike on You Tube doing over 220mph.

Add a couple of turbos and a 100 wet nos shot and I reckon that mini is quick!   s:crazyeyes: :crazyeyes: s:crazyeyes:   Did he build it himself? Hats off if so!

I'm not so convinced it would work that well in the '2, given the extra weight of the car over something like an old Mini chassis or a Radical. You need a bit more torque than a bike engine can provide to get the car moving really, so whilst it may work as a purely track engine I can't see it making any kind of sense on the road. That said, I'd love to see it done though!   s:D s:D

i agree with Dan, dont think a bike engine will be that good

quafe do a bike engine to car gearbox btw

[nitro]

tuning companys have been getting  350 to 500 bhp out of these engine thats reliably bhp the
weight saveing of a bike engine is a big advantage alone.  s:D s:D

Thing with some of the big bike engines is that they are only the start point for the enthusiastic tuner. The Suzuki lump will go out to 1.5L and with porting, cams and correct pipework can get some way past 250bhp without spending a fortune. There is more to come if you want to go FI. It is a light weight engine too. You get a decent sequential gearbox like the Quaife and you have quite a car on your hands. Trouble is, if you are going to spend the time and money making a car that serious, you will need serious handling to match, so you would more likely put the engine in something more track oriented. Mind, an Elise with that setup?

Some guy up in the Midlands was making V8s based around a pair of GSX lumps on a common crank and was seeing around 350bhp.

+1, you're totally missing the point. bike engines arent designed for torque because they dont have much weight to push. you can have all the power you want but with no torque to drive it you've got something thats, in a practical world, unuseable.

not knocking you for having an idea, but its really not going to work the same as a smart car or a Mini because we're carrying 50% extra weight or more, which is a lot to push off the line

if you're looking for a high revving engine a better route would be to spend the conversion money on forged pistons etc etc etc and running a high revving N/A 1zz or 2zz

+1 the mr2 is light but it's still twice the weight of most kit cars. also, it might get a bit annoying not having the ability to reverse.

remember that will be BHP/Ton

so if that were 350BHP/t on a 500Kg car then on a 1000Kg car it would only be 175Bhp/t which aint worth the development cost and isn't very good in the performance stakes of motor bike based cars. Plus the extra weight will sap the torque on the small literage engine at low rpm

Not BHP/tonne, actual BHP. Because of the very high rev ceiling a lot of power can be made at relatively low boost and torque, meaning relatively cheap reliable power.

I agree with all above. Yes, you can put a hiyabusa in pretty much anything thanks to the size of it and range of aftermarket products, but no, you shouldn't put it in anything heavier than 500-600 kg including driver as its got no torque. A mate is in the process of having one put in his 250kg single seater, at a total cost of £4,500. Spoke to Paul Woods the other day about the cost of a V6 and he quoted £4,500 all in. Should be an easy decision based on that!

any links or contacts?

I will try and find something. I remember reading more than one article about his engines over the ast year or two, but not too sure where. Quite possibly got a mention in Evo in the last 12 months?

Much better to just buy a Radical

Have to confess that a similar thread on SC unearthed this:

Looks very nice does it not? Sound must be awesome.

Fantastic support for a race engine! Most come with a FO great big bill when they go pop.
