Has it been done before? I'd love to do it ;D Had a chat with a helpful bloke from Bogg Bros who reckons, were I to supply 5 carbs/throttle bodies, I'm looking at £400 in all inc the custom manifold and a rolling road session. Would just like to do somthing a little different with the audi lump, esp given that it's just a wee 1921 cc  Any info would be greatly appreciated..... |

Id say go for it mate.
Ive never seen a 5 pot running on bike carbs before but would imagine they would make a fair improvement and give better potential for further mods.
Normally tuning the non turbo versions are held back by the k-jetronic.
I know the 2.2 10v has the potential of around 170 bhp by fitting a big valve head and the usual exhaust and intake mods or around 200 bhp by having the above mods and increasing the capacity to 2.6 using a crank from a 2.5 tdi.

Its just a lot easier, cheaper and simpler to find a 200 turbo and swap engines...... You could buy one and do the conversion and have change from £400  oh and 200hp as a starting point  |

get two sets of carbs, second one can be crappy as you only need one..
fit them together, which is not too hard cos they are made to fit together.. and bolt them on.
just make sure you get carbs that can handle the amount of air.. for a 1300cc engine it is no problem cos the bike has more HP to begin with but with a 2.1L it could be more of a problem to get them big enough.
400 is a lot of money though.. you could make youre own manifold and let them do the fiddling will save you a lot of money. allthough they're not that hard to get adjusted cos they do half the work themselves being CV.

The 20v 7a engine is also a good upgrade from the 10v but i reckon you should go for it as its something different.
Keep us posted on which route you go down.

Carbs don't know what the engine's capacity is. They only see airflow. The best guideline is to look at what power they can make on the bike. Most 'big' bikes can be massaged to around 200bhp for an I4. So 250bhp for a 5-pot? Plus they will take 1bar of pressure...So whack a blower or turbot on the side. *n |

Well cheers for the input guys - I was only looking for a modest power hike if I'm honest - 150bhp would be nice, and easily achievable. If I was to go down the 200bhp+ route then yes, as Dom says, a bigger engine would be a much more sensible starting point. That said, as Penski suggests, having bike carbs in the first instance would enable some serious turboing afterwards when I accrue more NCBs and earn more than a grad engineer wage! Would a manifold made to fit a 2.1 or 2.2 fit my 1921cc ? just thinking that If I could get hold of one then do what the guy off ppc (link above) did and 'blend' some carbon fibre with the 2.2's original manifold so that it could accept bike carbs.... All of the above could be completely irrelevant, however, as she's in for MOT as I type *yikes!* |

Not sure on the fitment of a 2.2 inlet manifold onto your engine i would imagine the heads are the same just obviously you have a smaller capacity bottom end.
All the five cylinders ive looked at appear to share a very similar design in the block.
Ive got a manifold for a 2.2 if your interested.
Where abouts are you id let you borrow it to see if need be.

Why go to the trouble of carbon when you could cut the manifold to stubs and connect to the carbs using jubilee clips and suitable hose?

Go to the MegaSquirt forum HERE and follow the link to something like "Injectors and Air Supply." Somebody is bound to have 'Squirted a 5-banger. There are plenty of motorcycle carbs available that are individual (single venturi) carbs and could be fitted singly - one per cylinder. Ditto for throttle bodies for EFI. Suzuki GSX-R TBs are single units, I believe. You could separate a group of four and lob another one in there to give you a row of five. You'd need to make up a fuel rail but it isn't so difficult. Also the throttle linkage would need to be adapted but again... ;D DO IT! DO IT NOW!  "I'm" |
