splicing bike engines together

[bje10s]

i heard this idea off another forum but they didnt go into detail...

im looking to move away from the 3sgte in my sw20 and have done alot of research on other options but none really hit the spot than came along this idea..

2l v8 rev happy

ferrari made a engine like this once and also a 1.5l

its a good idea if it could ever work.. and thats why this post is up.... IS THIS POSSIBLE????????? nothing has come up in a search

Yep been done mate and now also twin turbo,look up SR3 in youtube for a nuremburg lap with one. Here is the place that developed the Hayabusa V8

If I ever won lotto one would be going into the 22,I kid you not!

good thinking, splicing engines is much easier than 1UZ into SW20 with ITB supercharger turbos

[Bored?]

There are (at least) two manufacturers of Hayabusa-derived flat-crank v8 engines: Hartley in the USA, and Powertec Racing in the UK. They are independent designs and differ significantly, though they both share Hayabusa heads, pistons, sleeves etc.

The PowerTec engine is used in the Radical SR8 (Not the SR3, which uses a regular four cylinder Hayabusa engine). The Hartley engine is pretty new, but has at least been fitted to a Lotus 7 replica and an Ariel Atom.

Its not really an intelligent swap for an SW20 though. These engines probably cost more than two modified SW20s, and would need to be emissions tested to be engineered. Considering their main advantage is that they weigh very little, they don't make a whole lot of sense for heavy road cars, where you'd be better off looking at larger capacities and forced induction.

riceburner. GOOD find mate. +rep for u

Another option would be de-stroke a larger capacity v8. With a custom flat crank, new cams (to suit the new firing order), lightweight valves/springs/retainers, lightweight short-skirt pistons (possible with the long rod-stroke ratio), intake and exhaust length tuned to the new redline, etc. etc.

It's all possible, and this is where some of the indy engines come from. It's not cheap or easy though.

does any1 have a tissue lol

i still think this is a very good option.... i love capacity and a good blower but that sound was amazing. has any1 found any kind of price on these things??????

[bje10s]

i found a price:

i got to find a sugar momma lol.... and sound like a easy install and universal gearbox mounting means less hassel

[oldcorollas]

main issue is....
you need a fully custom crank, a custom crankcase (assuming the barrels bolt to the crankcase), and unless you stuff around with cam belt/chain at each end, you may need to make a mirrored head (ideally)

so.. the only thing you use from original bike engine is...
rods, pistons, 1 head....

it is almost cheaper to just fully make a whole new engine.

as for rev happy, you are still limited in redline by the rods, and by the valve actuation..

[deviant]

The ones already available are not cheap and are very much race engines. I believe the Powertec one needs a rebuild every 30 hours...so in a motorsport application that would only be once a year so represents good value and a good life.

Personally if I was going so far as to get that kind of engine I would save up a bit more and get me some Judd V10 of Cosworth DFV love....yes thats right...an Ex-F1 engine in my MR2..

Back in the realms of reality you could pick up a Ferrari/Alfa V6 for not a huge amount of money. I dont think it would be to hard to find yourself a F355 engine either...you would just need to be damn carefull it came from a car that took a frontal impact and is not from a stolen car....when I say 'not a huge amount' of money you are still looking at the 10's of thousands plus the cost of making it run and making everything else on the car handle the power/torque/speed etc.

Even tho I own an Alfa V6 (only a single cam 12 valver), I wouldn't get excited about putting 1 in anything else. They can be built with twin cam, 4 valve heads and the capacity taken out to 3.8 ltrs, but that's would cost abou$25/30k US. They do sound nice, tho .
How about a Honda NSX engine ?

i,ve got a twin turbo maserati all alloy v6 . just the thing for your bus .might be for sale. cheers bigwad

aaarrggghhh, runs away screaming in terror........
if thats a bit complex for ya ive got a 1912 sidevalve overlander you could de-stroke and have a bit of play with. No doubt given a set of cams and some boost she'd see and easy 25 hp
why make life tough? i can understand repowering a f355 or alfa due to the syphalytic nature of the factory power plants, but why would you take the worst and most expensive part of those cars and put em in a toyota? flip, the only real advantage those engines have over 1g/j/u motors is a nice farty noise, not enough incentive for me.
stay toyota. easier. cheaper. faster. more reliable
