Help with R1 bike carb conversion to 1.8 8v Gti

Hi, I'm new to posting on here but been looking through the forums for help on my Mk1. However, I just need a little help with converting the fuel injection to R1 Bike Carbs. I've got the R1 Carbs and the manifold, just need help on what else is needed. I've got a basic idea of what's need but help from others would be appreciated. I.e fuel pump things along these lines etc…. 
Cheers

I have R1 carbs on a 16v and I used the standard R1 fuel pump with a filter king regulator and filter.

Carbs
Manifold
Fuel pump
Fuel filter
Ignition control (megajolt)
Throttle cable

Are you thinking of using the standard ignition setup?

Its a bit of  backwards step putting carbs on a gti?

Thanks,

Dan

  Hey Dan,
thanks for replying. I am thinking of keeping the original ignition setup.
From the what I've seen it looks like the best modification to add power for cheap compared to other options. Is there any other modifications out there that can add similar increases like bike carbs but with out changing the fuel injection set up?

I don't think they will give more power, k-jet is capable of more than the standard 112 bhp, I think you need to be looking at substantial cylinder head and cam modifications to make use of more air/fuel, or better/cheaper a 16v conversion.

I'm not really the best person to ask about bolt-on GTI mods i'm afraid. I have always had a carbed engine.

However IMO the best place to start is to make sure the engine is as good as it can be to start off.

Good service,
new plugs,
new leads,
new dizzy cap,
new rotor arm,
decent air filter
new fuel filter
check the timing is correct
use decent fuel

I believe you can upgrade the Warm up regulator and throttle body for mk2 ones?

After that things tend to get a bit more expensive. A decent exhaust will make it feel more responsive and maybe sound more sporty but wont gain you much power.

I guess your really looking at having some engine work done then but I'm assuming you wanted bolt-on upgrades really?

You have to remember that the R1 or any other! motorcycle carb's were designed and set up for just that- a 1000cc (not 1800cc) high revving motorcycle engine! These engines spin to 14+K revs and are completely different from the rev band in the Gti.
Just because they look cool and fit does not mean their superior to the fuel injection system that (you) have. I would suggest not.
Obviously if someone had the time and money (or has a carb engine already) you could, using a dyno' change lots and achieve a good compromise so they would work  well, but I doubt they would straight off the R1 though I may be wrong!.
Perhaps go down the route of Dubstar to achieve a stronger engine delivery.
Also good gas flowed head would make more power.
Is it the look your after? then maybe go for it! but you may pay in fuel and tractability.
Alternatively, especially as you have bought the stuff, do the conversion–but keep the fuel injection system so you can swap back at a later stage.

  I've seen some come to 150hp around that area with this modification. I can always sell the manifold and carbs as I got lucky I got them for cheap aha. So I may take a look into cylinder heads.

  Hi,
Sorry I forgot to mention the car has a 4 branch to a custom made power flow exhaust. But I have heard about the throttle change from a mk2 golf or from an Audi 80. Doesn't add much Hp but throttle response is increased. 
And the engine is running great just had it rebuilt and put back in the car and I run it on V-Power. Just looking for a bit more go really aha. 
Cheers,
Zac

  Hi,
Wasn't for the look but for the power gains really. I may just sell the parts I have as mentioned before I got them cheap which was lucky aha. I'll look through the route of changing the throttle body, intake pipe and maybe a cam.
Thanks for your input!!
Cheers,
Zac
