Suzuki GSX-R250R modification?

[caspernz]

Don't waste too much money on it with "performance" mods that give minimal (if any) gains in power, especially on a bike that's not worth much come upgrade time. If you start fucking around with removing the airbox and replacing it with aftermarket intakes it will probably won't make any noticeable difference, except to your wallet. If you want to go faster, then buy a bigger bike.

Yep, old small bore bike...anything along the lines of performance improvements is akin to the bottomless pit

The GSXR was the worst of the 4 cylinder 250s.

Don't waste your money any further.

[Mike.Gayner]

Ok so general consensus:

Fairings etc all good but air intake no good unless lots of money spent.

So Turbo is the way to go then.

Does anyone know of someone with a bit of experience in this who could help with this? Failing that I can just let the boys from work at it, I do have a spare engine as well so will be using that as a dummy until it is running correctly.
Thanks

How the fuck did you get THAT message from what people said?

Do a skid or a wheelie and post up the video.

No-one said no to the turbo at that stage. Still will do my research otherwise there are other ways to go to create a suicidal 250 on a quarter.

And at the end of the day I was asking for help in doing it not whether or not you agreed.

Wrong forum bro. Bikes of that vintage don't do well when the "mutton dressed as lamb" intent comes along...

I have a better idea. Get four of them and spend the money crafting a crankcase to graft them all together to make a one liter v16. Then we will be impressed! Well, I will

Nah, lengthen the frame. Put four of them in behind each other, hydraulic pump on each one. Dark side the rear end and sell it on Trademe.

Those engines are already very highly tuned from the factory. Unless you're willing to spend more money on the bike than it's worth, you're either going to end up with:
1. Minimal performance gains that are barely noticeable.
2. A decent power increase, until it blows up a few days later.

If you want to go for a turbo setup that lasts more than a short thrash, then you will need to build the engine up properly with new pistons, rods, etc. By the time it's all been set up properly, you're looking at $5k+. Finding a small enough turbo is also going to be a hassle, unless you're willing to put up with severe turbo lag which will make the bike a cunt to ride. It's a fucking huge job to do it properly, and there's no simple way to do it.

If you absolutely must turbo a bike, buy a cheap single cylinder dirt bike to fuck around with. That way when you blow it up you won't lose much money.

By any chance are you Chaos Rider's brother? I remember a certain thread 4-5 years back... "Evolution of a monster" I think....

Anyhow this has to be a troll, cause no fucktard is ever this stupid.

$5000 - 8000 to turbo that bike. 250's have been turbo'd before with small daihatsu turbos (charade 3 cyl motor) or possibly even a turbo for a honda city (if you can still find one).

It will have to be converted to EFI and run a liquid to air cooling system (or meth injection). All parts will have to be custom fabricated.

If your deadset on getting a turbo bike save your coin for a busa than kit it out with RCC stage 1 kit. You can put it together in a weekend then all it needs is a tune.

I have 15k budgeted for my build this year which I will hopefully start around the end of winter.



Don't let anyone tell you what you can't do with your bike, if your dead set on making something work WITHIN THE LAW. Then do it, its your bike

It could be turbocharged with carbies, so it doesn't really need EFI. Either way it's still going to cost at least double the value of the bike.

I wouldn't trust a turbo with carbs on a motor that small. Shit will go boom.
OP should really just save for a busa

Pretty much.

I will have to retract this statement. I'm reading the chaos rider thread. Somethings just shouldnt be done
