16v on bike carbs, they're on at last... P5

Right, I am a total novice so bare with me... I'm looking to put bike carbs on my 6a so

Which carbs are going to be best?

Would I need to modify the carbs/jets at all, if so, details?

I intend to just chop up a standard 16v manifold, block the injector holes and join the carbs to it with samco, can you see a problem here?

I gather I can use the fuel pump from the same bike, true?

What about the pumps already on the car?! Do these stay??

Could I just get some kind of pressure regulator rather than another pump?

Do I need another pump at all, or will the standard ones do the job..?

Do I need to worry about anything plugged into my K-Jet or can I litterally just bin the lot and leave the wires unplugged?

Anything I've not accounted for?

Ta!

 

you will need to reduce fuel pressure down to about 4 -6 psi for a carb setup.

the GSXR carbs are popular and flow well, try and get some from a R6 or the R1 altho any of the racing type bikes will do, i wouldnt buy anything from a bike smaller than 600cc tho.

I am going to be using samco' to connect my ITB's so i hope there isnt any problems

 

Speaking from experiance here, keep the samco lengths short. I tried to extend the length from the manifold to ITB by using a larger length of samco. All it did was collapse when at idle - the vacuum was that strong.

Thinking about it now it seems so obvious.

 

This will be interesting to follow....

Could you keep us updated on your plans/costs incurred etc.

How much do you foresse this project costing???

 

Thanks fella's keep the answers coming (particularly about the pumps..)

Will try and keep this as comprehensive as poss and maybe make it into the FAQ's?

Not planning to spend much at all, unless I need anything else, I'm thinking sub 100...

 

You will need to keep the KR ECU and wiring for the spark map.

 

you could probably convert your car to the carb'd golf fuel pump setup, for little money, plenty of driver being converted to GTI spec system.

or as you mentioned use the bikes pump.

 

guys you can get "vacuum" hose which does not collaps under...er...vacuum

 

just use a fuel pressure regulator surely? Cheaper and easier to fit??

 

Ok, so I could use my standard 16v pumps, with some kind of regulator? Where can I get said regulator, and how much?

I really am totally clueless here, I'm gonna need every detail possible

I figured I'd need the ECU, is that all I'd need to keep? What about all the crap plugged into the airbox/inlet mani area nothing important there?

What about modifying the carbs themselves? Any details on that, or could I just plug and play..?

 

16v pump is way too much, a regulator that knocks it down to 3-5psi would probably just heat the fuel up

 

i am going to be starting this conversion on my mk2 abf at the of the month using cv40's off a kwak zx9r i am using a facet red top pump and a filterking regulator. i also planned to do the same as you using a modified standard inlet manifold but i'll have to space my carbs out

 

you keeping the ecu for sparks?

 

This looks interesting has anybody tried one ?

looks like a good idea, shame they dont do a manifold for the 8v / K7 conversion (Throttle bodies rather than carbs), altho i would want to be respacing the TB's as they come with a TPS so i wont have to mess about setting the TPS up, i hope!

 

Im wanting to do this to my 2l 8v engine sat in the garage, had a change of plans and this might be exactly what im looking for.

 

we did it in a Mk2 Escort , with a Zetec... used a Facet RedTop , with a Filter King Regulator , the main jets will need resizing , we went from 120 mains to 180s , on CBR900 Carbs on a 2.0l . We also changed the low end jets , from 0.40 to 0.42 . Experiment first with micro drills , then buy jets the size you want .

 

Right, so, just a simple answer then

Do I need the pump from the same bike?

If so do the pumps already on the car stay or go?

If not, where can I get a suitable regulator and roughly how much, and will it do the job safely/adiquately?
