There are already bikes using 800 and Gypsy engines. Several automags have published stories about them too. Can't remember the issues though. People like you and me built them using their imagination, resources and skill. In any case, the chassis would have to be HEAVILY modified to fit in and bear an car engine. - MAX.

Car engines are much heavier than equal displacement bike engines. So even if one strengthens the chassis at engine mountings, it will ultimately take its toll on the other sections of chassis.
Btw has anyone given a thought to importing a 2nd hand cheap 500-750cc bike engine from abroad? Fixing up one of those engines in our bikes will be easier I guess.

hey rohit,
importing a 750cc engine is no problem, but i guess no Indian bike chasis will be able to take the power of these engines. U will have to strengthen the chasis. and then theres the issue of tyres [stock tyres will be bald in a few days], brakes [atleast a 280mm front and a smaller disc at the rear] etc

Actually I'm more focussedon a 500 or 400 twin cyl 8 valve engine. Like the '89 Kaw ex500 for example. And I think the chassis will quite easily take the load of a twin 500.

**V12** · 11-01-2003, 09:57 AM

oh twin. ya then it will take. i thought an in-line 4.

**rohit_180** · 11-01-2003, 10:07 AM

Only problem in getting one from ebay is that one can easily get cheated by customs and the sellers.

hi,
Here in hyd i heard of a guy from chennai(who was in hyd) got a maruti800 engine fixed into his bullet chassis after modifying the bike heavily. Though i have not seen him or his bike many say that such a bike exists and here in hyd. will let u guys know more if i get any info...

**aspirin** · 11-01-2003, 01:18 PM

Isn't M800's engine just 37BHP ??? If I'm right, anyone who's putting a M800 engine on his bike is fooling himself. The power/weight ratio won't be favourable, and definitely not anywhere close to even a CBR.

**boneythegreat** · 11-01-2003, 02:03 PM

now why on earth would anyone wanna fix an 800's engine on a bike? come on guys a new bike is always better. u think an engine as big as that is gonna fit on a chassis thats built for a cbz or a pulsar? ooooohhhhh puhleeeaase. may be its gonna look rad but in the long run is it just worth all that mods to accommodate a 37 bhp engine?just forget it man get a karizma if u got that kinda cash.

**satya** · 11-01-2003, 03:03 PM

hey if the 796 cc 37 bhp engine of the m800 can propel it to 145 kmph
im sure it can power a bike half its weight to much more than dat
but fitting a car engine on2 a bike has complications like mating it 2 a bike gearbox( wont it be silly shifting like a car on the bike

)
also shaft drive comes in2 the question
morever
a complicated affair

agreed!..selecting a gearbox would be the biggest challange..car engines dont have as much power as bike engines of similar size...but they make their power at a much lower rpm with a lot more torque(which is not nessary for motorcycles)....even if a gear box is found the power delevery would be jumpy....But this could be intresting...if the m800 engine comes cheap it could really be worth a try......

overdrive long time ago printed and article with 3 surds from chandigarh, who used M800 or gypsy engine on a bike which they made, rear tyre was of safari only problem was that safari tyre used to lose a lot of traction on steep turns, the bike also had the radiator mounted on it

Chandigarh, May 8
Financial constraints seems to be no limit for Jeewanjit Singh, a city resident, who has modified a motorbike by fitting an engine of four wheeler.
A lover of bikes, Jeewanjit Singh, completed his diploma in mechanical engineering from Lala Lajpat Rai Memorial Polytechnic College, Ajitwal, near Moga recently. He opted for a topic on modification of bikes in his project report which was to be submitted during the last semester of the diploma course. He succeeded in giving the final shape to his idea after one and a half year’s hard work.
On a manually developed frame, he along with his batch mates — Swarn Singh and Gaganpreet Singh — from Ludhiana fitted a Gypsy engine of 970 cc capacity with a gearbox of Yamaha 350 cc. The rear tyre has been replaced with a Tata Safari’s tyre, while that of a front with the rear tyre of a motorcycle to make vehicle stronger.
While talking to Chandigarh Tribune, Jeewanjit Singh said the petrol tank of the six geared bike has a storage capacity of 10 litre and can run at a speed of over 160 km per hour which could be raised upto 200 km. In a long drive the bike gives an average of over 20 km per litre.
“My parents and brother inspired me a lot to achieve the goal. My elder brother, Mr Jatinderpal Singh, gave the idea to modify a motorcycle by fitting an engine of a light vehicle some years ago and I tried my best to prove it”, Jeewanjit Singh added.
After a similar bike with a Ludhiana resident Mr Davinder Singh, he claimed that his bike was second in this region. “I will keep giving shape to my ideas of modifying the bikes but need a job at this time,” he said.
