Yes, you guessed it, the speedo is Syncro specific and has a W value of 1740, the 2wd Golfs have a speedo with a W value of 1540, [
]
the part nr for the speedo head you need is 193 957 033E
btw that is one part that I do not have laying about here as all mine read in kilometers
Do you still have the old speedo head? if not then anyone on here who has swapped over to an 02C cable change gearbox should have one, as they will have needed to fit a 16V GTI speedo head in order to read have it read correctly. [

yer, now what you mean about eating aluminium,
But if you add 1-2% water, methanol isnt corrosive.[

Will need to increase the compression ratio to make it more economical tho[] after converting i gona try a hydrogen generator so more bang for the buck[
]
or add more pressure to the intake . meth isn’t really a practical road fuel i used to like the idea of it but it is proper nasty stuff to handel and you really don’t want a fire as you can’t see the flames and it finds a lot of ways to get itself ignited.
high cr is not doable on a budget sadly it all gets quite involved very quickly. and as for those hydrogen genorators they are a load of crap they only make the engine run smoother as it’s pulling harder against the alternator to generate the electricity used by the “hydrogen genorator” if you actualy power a “hydrogen genorator” off another power sorce and feed the gas to an enigne it has naff all effect.
look at playing with fuel injection that will bring good gains in power economy and reliablity. the other good trick that is proven to work is water injection, add water at about 25% the rate of fuel to the inlet manifold as finely atomised as possible, engine will run cleaner, and more efficently and make a bit more power as well with the rest of the enigne setup to work with it
normal motors, they love it. the only reason cars don’t do it from factory is that there are rules about not haveing consumables in emission control equipment or some crap like that. water injection is quite intresting imo as when setup properly the water actauly plays an active part in the combustion prosses. it not only cools the inlet charge but during the compression cycel some of it will grab hold of and breack aprt o2 in the cylinder 2x h20 + 02 = 2x h2o2 this means that when the poowerstroke starts free oxigen is released that hels burn stuff that din’t want to go the first time round, the rest of the water will keep the cyls nice and clean and drop exhgaust gas temps but cyl pressures will go up slightly
leave the fueling allone just add water upto about 25% rate of fuel. ever noticed how keen youor engine feels on a foggy morning has pritty much the same effect but with the bonus you can see where your going. it dosent add masses of power but should notice the differance it also has bigger effect in hotter weather, on some enignes it’s possible to run more ignition advance as well espectaly the older desings of engine.
avoid putting to much more in tho it dosent do anymore just causes problems and mean haveing to carry a lot of water.
a good trick on k jet 16v’s whitch allway seem to run a littel lean when flat out and pink on poor fuel when flat out is to use 50-50 water alcohol and you dont need meany bits to intall it
water resovor = screen wash bottel
pump = window washer pump ( out let to rear screen washer is top favoret)
atomiser normaly nicable from some plant sprayer thing wants to flow 250 ish cc min for water or bit more for water alcohol mix
some 6mm aquarium airline 1 T and a stop valve, bring feed from pump to the T then connect the valve to other port of the T and from the valve run a return to the screenwash resovor. connect atomiser to remaning port of the T. use the valve to adjust flow
trigger pump with WOT switch tho can start from 70% throttel
that sounds like a very interesting idea indeed danny and given I’ve got a gti 16v Kr and the exact same in the syncro it probably warrants looking into. I always carry water anyhow because it gets a bit thirsty when tickled.
I think I do actually do run the ignition quite advanced although not sure by how much. I just adjusted it till it came on power at what seemed like the “right” point (about 4k) but before it started to complain. I also run it rich because as you say on 5th-gear flat-out it leans out so the water could be just the ticket since it’s a bit “phlegmy” at anything less than 5th gear wot. This might mean I can roll it back a bit but not lose top end. I bet the mpg won’t be hurt either!
When you say alcohol I presume you don’t mean methanol? but then what? (lager injection?) tbh meth sounded like way too much risk/hassle. I already encounter more than enough noxious fumes as it is.
Re the atomiser – surely a setup like the fuel-delivery pipe in a weber carb would be ideal? (i.e. pipe into middle of airstream). I can’t quite visualise what 250cc/min would be vs the air flowing but I guess this goes in the inlet tract about where a nos dizzy would go? in fact wouldn’t a nos dizzy be about ideal? Basic airbrushes just have a fine nozzle in an airstream and can give pretty decent atomisation.
When you mentioned how some of the 02 can break down from the water and provide extra bang – what governs that – how finely atomised the water is?
I’ve actually got a wizards of nos pulsoid sitting here.. I bet it could be repurposed for water 
Hmm trying to work out where toput the extra washer bottle…probably in the boot..
See if you can find avery early 84 or 85 Golf 2 on the scrapyard, as they had a seperate washer bottle/pump unit expressly for the rear screen, it fitted under the carpet in the rear right hand wing after the wheel arch.

Have Fun! []
oh sweet… that would be a nice plan
hmm no scrappys near by, there’s a VW one a way away but whether they’re still going or not I don’t know. Will have to check..
feeding it alcohol is pritty much risk free you just mix it in with the water like screen wash 40% alcohol solution dosent ignite that readaly at the end of the day alcohol is often a magor component of most brands of winter screen wash . it just bumps the effective otane up and give the motor a littel bit more fuel as well for no extra effort. you can get the alcohol in form of screen wash, methalted sprits ect.
it wants to be prayed in just before the throttel body body, a venturi of some sort would work. but the finer the atomisation the better i wouls say a fuel injector from a gti would be optimal but it would need a 3 bar feed and not sure if water would kill it.
the water itself dosent breack down but under right conditions (pressure and heat) it can help breack down molecular oxigen in the cylinder and grab one of the oxigen atoms, forming h2o2 but the bond holding it together isn’t that strong and when things get a bit warmer it’l jump off to go play burning with the fuel. no oxigen is ganed or water used they just take a littel detour the water needs to be really finaly atomised for this to really work tho. i think fog would be optimal
