Hayabusa or S2000 - Opinions
 

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......

:p I,ll have your Zetec setup :D

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

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:eek: it won't need any and ice cold cool factor on lifting the bonnet :cool:

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 :o :o

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 :cool:

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 :D

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:(

Honda lump all the way. I love bike engines ......................in a bike :D

Don't disregard the zzr 1400 either, apparently they feel really torquey even in a seven. That's what's going in mine when I get bored of the 9r motor.
Im sure as well there would be a massive weight advantage going for the bike engine so therefore better handling as well.

there's a nice type r in North East Motor Salvage (Peterlee) here is the link

I know it is the K20a2 engine which is 150cc's less than the s2k but it might be cheap as its is a breakers car cat B (back end totalled)....just a thought bud.

Mazda with extra go faster bits because would cost a lot less so you get more smiles per mile as not cost so much to do.

Unfortunately type r engines turn the wrong way, would be very quick in reverse though.

just flip the diff

Is it as simple as that?

why not since the mounting would be bespoke any way and diff itself is sealed

Im surprised nobody has done it then, it,s a cracking engine I've had 2 of them.(type r's that is)

Some good thoughts cheers.

Think i've made up my mind to go with the S2000, when i upgrade its got to be a mega machine. The bike engine would be awesome but would be a lot of hard work with normal driving and probably get sick of the constant gear changes and pitch of the screaming engine. The S2000 seems the ideal engine for the roadster. Going to find a garage with one in and give a test drive for final decision.

Thanks for the input.....Andrew

Why not Mazda/Duratec 2.5 / 3.0 V6 with mazda 6 speed box and show what the new chassis can do, just a thought. :D

Makes sense to go the Mazda route as cheaper than a bag of chips and lots of whizz for your wedge

Track flea = bec
Road = car engine.

Worth pointing out if flipping diff to re configure oil level to lube pinion as it will be running dry and vent if applicable.

Bob

flipping the diff over in trikes is very common
been done loadsa times
cheers les g

Is a flipped diff the type Jonathan Ross would use:D

oh dear you will end up on the naughty step again .
or like me have your posts deleted
cuz you wear the wrong colour socks
cheers les g
ps you have a pm

My step and only enough room for me......:D

Honda S2000 all the way, suits the roadster perfectly in my opinion, light, powerful, 6 gear box, lots of revs but not excessive torque low down. shame you may have to go aftermarket with the ecu but I think the DTA S60 ecu comes with a base map for the S2000 and supports all the engine sensors with no calibration. I'm having second thoughts about a turbo in a roadster too.

Gonna regret this
 

Firstly, excuse my ignorance :o

What car used the S200 engine ?

Kinda guessing it is fitted to a Honda but what model ?

I await the ribbing :D :D

The Honda S200 used well errrr the s200 engine:D It's one of those fancy vtec type devices made by the devil:D

Told you I was going to regret it :o

I have only just been weaned off the Pinto & Austin A series engines don't yer know :D :D

All I hear at home is Scooby this, Evo that & the odd Skyline thrown in for luck :rolleyes:

Here is a good one for you all,local to me is a well known german car specialist who even gets the dealers in to sort their problems out and has invested mega bucks in diagnostic gear,in comes a J reg scirroco and they are all stumped as how to alter the mixture on the "Carb",they had to call in one of the lad's dad to sort it.

What is the world coming too.........

Technology ? :rolleyes:

Back to thread,what about tb's and a head change instead of ripping the lump out and fit emerald or the like,should give decent power.

I'm not into all this modern stuff either Ronnie, my daily runabout is a 1983 Vw T25 easily fixed with a hammer and a screw driver. No fuel injection no cat but it does have a cool way of letting me know when it needs more oil.....cheeky wee puddles are left as a reminder the oil prefers to be on the outside rather than on the inside. Had the crank seal changed and using thicker oil helped but still does it......"tis human don't yer know"

Oh and the other thing I beat everyone in a race down here as I just block the road and drive slow....:P

s2000...

they fit nice with a little modification

Well i believe my mind is made up ---- it's got to be the S2000, only thing left to do is a test drive without the salesman for a good test......:D

Didn't realise you were fitting one Tilly, they are a lovely looking engine and do take a lot of stick - good job really. I maybe be pestering you at some point if you don't mind.

Sorry Mark but you'll have to upgrade over the winter to to keep up. Not the VW but the ST170 Mark......;)

Thanks All......Andrew

I kinda like being a mobile chicane and amuses me to see how it winds people up being stuck behind a camper with sarcastic stickers on the bumper....sooooo many folk in a rush to get in a wooden box these days:confused:

I knew mine being faster would eventually get the better of you :D

You will struggle on the test drive front though as i only just fit in them and you are a good couple of inches bigger than me, you might just have to put the roof down and look over the top of the windscreen instead!

Hmmmmm. As most of you know I sold my roadster and used the money to buy an XJR. This kind of got me thinking. The Jag V8 engine is actually very light, as is the Merc 5 speed auto trans (yes, I know, but bear with me). My car has been lightly tuned to about 420 BHP, in the very big Jag it does the 0-60 dash in 5 seconds and storms the 0-100 in about 11. Top speed when derestricted is 180. I am told it is a fairly simple matter to up it to about 500 brake.
Now, I don't know if that engine would fit or whether it could be mated to a manual box but I wouldn't mind trying :D You can get a decent Jag v8 engine for about 350, an auto box would be about the same albeit totally useless for a roadster.
Failing that the Honda would seem like a great choice.
Dave.

I found this a few years ago and the big one is the modular ford/jag.Its actually bigger than an fe big block ford.

hi spud - it seems you have made your mind up about the s2000 engine which is good

but

make sure the power you expect is the power you will get or you will end up doing the modified route to that which is an expensive route.

with regards to the hayabusa

1. the bhp figure from new is about 175, not '200' [less any loss.]
2. driving the car - there is very very little loss of torque with the busa i have noticed - if you drive it correctly you should be in the right gear anyway!!
3. the sequential box is a dream!! on full throttle shifting it just clicks into gear with very little lift off at all even without a quick shift.
4. the reverse boxes are shit - plain and simple but you can go the starter motor route which works very well.
5. weight - the whole engine and box weighs in less than the weight of a s2000 engine alone
6. reliability - DONT FIDDLE WITH THE ENGINE if you do you risk it going bang - they are designed to be run in a bike as you know and right on what is very close tolerances - leave it alone and it will be ok in standard form.
7. performance - best mod for any car has got to be - - - - suspension set up! worth 100 bhp any day. theres not many cars get away from my car the only one i had pass me was a 911 GT3 [with 450+ ponies] and i wasnt watching :rolleyes:

if your gonna use the car a lot on motorways - car engine - it can get tiring in a bike car

but back roads - see ya!

:cool:

Turns out its dead easy to make the S2000 engine run on the standard ECU ;) you need the engine loom and the under dash loom complete with the PGMFI relay

if you go down the s2000 route give me a shout and il tell you were to connect the wires, you dont need to touch the engine loom and you need about 30 wires from the under dash loom

tilly
