Hayabusa or S2000 - Opinions

[spud69]

Got a bit of a dilemma, i've finally decided i fancy a change to power plant in my Roadster. After chilling out camping yesterday and listening to all the motorbikes screaming along the Stokesley to Helmsley road (an infamous biker and roadster stretch of flat out blasting) i need something along them lines. So is it to be a Hayabusa, 200bhp, expensive but the bike engine to go for or a Honda S2000, 240bhp and 9000rpm. The S2000 engine would give out something in the middle of the Zetec and bike engine. A good S2000 engine can be bought for a full kit of engine, gearbox, loom plus other bits for 2.5k, would also sell my own zetec inc gearbox, carbs, exhaust, megajolt, fast cams to recover some of the cost.

Got plenty of time to consider as i'll be doing this following completion of the single seater as a reward to myself. It would certainly be awesome either way just cant decide which way to go, don't really want a turbo engine as i dont think it would really suit the roadster for the way i drive.

Does anybody have any other thoughts on which way to go.

Cheers.....Andrew

S2000,more reliable than bike engine and less likely to go bang every five minutes, expensively......

[HandyAndy]

I,ll have your Zetec setup

Andy, forum member "Tex" from Stockton has the hayabusa fitted into his westy .....chuffin quick

cheers

Agreed,personal thought just dont fancy constant gear changes and falling out of power band,clutch replacement and you need a sump change to stop surge,Honda motor for me.

Its a no brainer Andy.... S2000... quite a bit of tuning gear to be had as well but with 240 horses already it won't need any and ice cold cool factor on lifting the bonnet

Honda engine for me too Andy

I don't think I could live with the full on mayhem of a bike engine on a long term basis.

Guess I am not the right person to have a view on this, I stopped riding bikes when they stated frighening the life out of me

Tis a nice dilemma to have though & whatever way you decide to go, I am sure that you will get plenty of smles from the miles

You already know what i think of s2k engines! they are a masterpiece, feel a little underpowered in higher gears in the s2000 but 1st and 2nd are frantic

Couple that with half the weight in a roadster and it would be phenominal

2.5k is steep though, find one in a scrappy that doesnt do kit car packages etc and you will get all you need for less than that

You also have to factor in the cost of a decent aftermarket ecu as the standard one is meant to be extremely difficult to use when its not attached to all the gubbins of the s2k

I built a car previously with a zx9 motor in and it was manic to drive,great for a B road blast but the rest of the time not so nice.I would look at it like this;

1 If your just going for a blast and trackdays then go the Hayabusa.
2 If you want a car to ramp the tits out of but also just want to go for a nice sunday jolly then go the S2000.

S2000....

Although a bike engine may have the ponies, it lacks on torque. They are not made to move the weight of a seven around and therefor need to be kept on the boil to have worthwhile performance and this will hamper reliability on the long run.
Another drawback is the sequential gearbox that will get tiring after awhile having to hit every gear changing down or up and cannot simply go from 5th to 2nd gear for example.
Lastly, reverse gear mods are always an issue (read expensive and problematic) with bike engine installations.

You guys are lucky to get that gem of a motor with box, looms etc for only 2.5k. In my country its scarce as chicken teeth at a breakers yard and the other day one was for sale without any extras for the equivalent of 6.5k English pounds
