has anyone got inlet manifolds for a 16v engine so that carbs will fit on them.

Hi...

There`s not a "bolt on" manifold that you can use...

You have to get hold of 2 intake manifolds from a 16v, and 2 from a 8v carb version....

Have to cut them in half, and weld the bottom part from the 16v to the upper part from the 8v carb intake...

Hope this helps

Do you mean cut the throttle body off the 16V?

I'm curious. So how is the power delivery? As compared to 16V ie. Anyone knows? I actually fabricated the linkage but has not embarked on the project.

So you get ard 20 bhp just from carbs?

On my previous series 2 1.5 TI, that i converted to 1.7 16v with carbs, i didn´t notice.
(because i didnt had driven any 16v, with injection at the time)

Now that i own a series 3 16v, i can say that on lower rpm, the carbed version was faster, and more rev happy...
Not much change on top rpm (lack of fuel supply cappacitty by the carburettors ?????)
The series 2 was also lighter, which helped a lot...

The sound was also better... lots of backfires on the overrun...

All the best

Hi there. May I ask which distributor coupled your 16V carb conversion?

I'm working on a 16V carb too. So which fuel pump you're using? I'm using carter. And my intended main jet, 160 with enlarged venturis. Since it's a modification, sure will benefit from you guys' experience. btw, gonna start a thread on final drive.

Hi im a guy from Denmark wich builds kitcar's on the VW type 1 chassis and uses Alfa Romeo boxer engines....the adapters for the vw transaxel to fit the alfa boxer is a part we ourself produce.....

Last year building my kitcar we ran into a problem - all racers used them but had never been produced in series prof... Intake manifol's for the 1,7 16v engine to adapt weber / dellorto 40mm karburators !!!!!!

I have seen many pour intake manifols wich we could call homemade
So my buddy Rolf and I desided to manifactor aset of super smooth super flow manifols - bolt on easy - made in one piece alu......

The price for a set of two manifol's are 3300 DK kr or about 472 euro !

Get more info write to me : kitcarlasse@yahoo.dk or +45 23 310 310
3D picture from the cnc-machine is possible to mail to you !

More info... our manifol is lower than them you kan make off old throttlebodys + lighter weight..... + much better flow and no blind ends from old injectors Shocked

SO YES THERE IS A BOLT ON MANIFOL FOR KARB/16V SOLUTION

Link to danish website with picture from our CNC machine :

http://vwnettet.dk/modules.php?name=Forums&file=viewtopic&t=16041&highlight=16v

As you can see on the picture is our manifol superlow, the vacum fitting are build into the socket, the optional hole for brake vacum + sensors are ready for fit if you need them, finally the cooling water comes through an stainless steel pipe fitted into the alu manifol with 40 tons off weight !

This IS serious Wink

Plastic is fantastic

--------------------------------------------------------------------------------

1 sæt special fremstillet manifols til 2 stk dobbelte 40mm weber / DellOrto'er til brug for Alfa 16v boxer motoren der ellers kun er lavet med sprøjt !!! Dette giver ca min. 160-163 hk...

1 sæt pol alu ubrugt manifols bolt on - 3300 kr

Rigtigt fint til feks en buggy / kitcar sammen med en Alfa Adapter

1 adapter sæt komplet bolt on 5000 kr

The low manifol is made like this to fit under any hood.... however the all can be fitted with a spacer to make the hight that you want.... We further can offer an special made set for you to fit a 36mm karb og maybe a 48mm ? If you order a set just tell how higt you want the intake manifol from the engine surface and up to the karburator surface.... your wich is my comand Shocked

Remember this is NOT an glue together part - THIS is made especially for you in one piece solid alu........ Very Happy

Cause off the pour conditions we have here in Demark regards building cars ourself.... the Alfa boxer is the only one wich are OK by the carinspection to get on the street..... Crying or Very sad

We soon will make an adapter for mounting bigger brakes at a 33.... anybody interested ?

Plastic is fantastic...... my kitcar weights total 620 kg and runs with a 33 1,7 16v engine fittede with two 40mm DellOrto karbs.... the tires are 205/50/15 and rear 345/35/15.... lightweight and good grip Wink
