i guess the lack of low down torque would be offset with a really high diff ratio.

the only issue with the motor bike engine would be more regualar servicing but you have to remeber that the 1000cc motorbikes are pushing about the 180hp mark these days

guess you get drive off the engine would be to remove the sporket and match the splines to something else.

reverse is your only issue really

motorbike engine into small rally car has been done in NZ more than once, and very successfully. suzuki hayabusa 1300

Beattie the 1.6 doesnt bolt up to the 1.3 box without mods. but possible.

The turbo zook drag racers have made more hp with the 1.3 for the bottom end of the 1.3 and rod stroke ratio. Unless you go billet honda crank conversion on the g16a/b the g13b wins hands down in turbo trim and all out power.

I have several 1.6 engines and after pulling them apart have now decided on the 1.3 for its bottom end. The crank on the g13b and supposedly g13bb are solid and forged where the 1.6 is hollow and the heads on the g16 series seem to suffer warping and cracking more often than the later refined g13bb. Rods on the g16 are spaghetti thin.
The forged bottom end o the the 1.3 allows it to handle over 350hp when its boosted. Wheres the g16 is around 200hp.
The jury is still out on the g16 cranks as many have bent and snapped at less hp.
Also the 1.3 blocks are way shorter (30mm) for clearance wheres the sump is also an issue on 1.6 engines. The stroke of the 1.3 is 77mm vs 90mm and both can be bored out to fit sleeves in the 78-79mm range.
Gozales in puerto Rico is using stock rods, crank and supposedly cast pistons! on a g13b turbo setup that is the fasted suzuki G series engine on earth. Currently under 9.90 seconds! He is the Guru on G series and will not use a g16.

Some have even used the stock hollow crank sohc 8v g13a engines to make over 180hp with boost. This engine is more reilable even with the hollow crank thanks to its rod stroke ratio.

What this translates to is a g13a is a 55kg engine that is found more comonly than a series engines.

If I had money though I would do a 1-1.4 liter bike engine setup which at around 50kg with 5/6 speed box and sequential shift, electric reverse and 170-190hp out of the box with no pollution gear is the ultimate in mass produced 4 stroke technology.

Id love a v4 honda pan european st1300 motor with a supercharger on LPG or the latest Vmax 1800cc coming out.

Their not a bad donk. But what alot of the Zook boys do is use the Baleno 1.6 engine insted. Then you get EFI, 16V, 1.6 etc. And the 5spd still bolts up. And Zooks have a seperate transfur case too so you can use the original box.

Love the idea of a motorbike engine, but would a lack or torque cause you any problems? Bike engines are designed to push at most 400kg I thought. Even the light 1k at 690kg from memory would be a little heavy for it.

But still it would be a worthy project for someone to try.

Now the new suzuki engine in the jimny, thats an interesting propersition. I wonder....

How do you get drive to the rear though???

Come to any of the Cams Supersprint rounds (one one 30th march at Oran Park). Pay particular attention to the clubman style home-builts. The slow one's are the 16valve or 20valve toyotas. The really shmick ones with the fast gear changes, chriping tyres on downshifts and sound like thorough bred race cars are the suzuki or kawasaki engined machines. But the way the are *heaps* quicker and look like way more fun!!!!

yep...didn't remove the gearbox bumps. because we wanted an option to put the 60 series back in if we needed (they had already been moved back once). So I used a bottle jack to gentle push them apart. First run it rattled in the tunnel at idle only. Before the next outing we changed the old toyota rear mount, which was very soft, to the setup of the 60 series rubber mounts on a home-made bracket. Hey presto! - runs great now.

why not go a 1400cc motor bike engine.

it would rev to next week.
sequential 6 speed (yeah six not five)

you just have to work out reverse.
electirc motor somewhere

The more I see a 4age the more I like it, gearbox available as in the t50 and a very compact motor. However a heavy little jigger which is only 8kg lighter than a 3SGE.

My other choice would be a complete suzuki jimny g13bb SOHC 16v with 5 speed. A semi bare complete g13bb engine is 60kgs for the complete engine including pulleys and other bits while a 4age in the same guise about 50kgs heavier.
