dont worry this isnt a which is better! more like a how can u tell which is which and whats the difference? thanks.
K-jet will have braided hoses coming from the fuel distributor, which lives on the driver's side inner wing. If it hasn't got those it's not k-jet & therefore is crap! (just trying to cause an arguement)
TBH I don't know which is "better", K-jet is simpler so therefore easier to fix but I guess that digi might be more efficient. Let the battle commence.
lol, well mine dosnt seem that easy 2 fix so i guess its a digi! lol so the digi is better then! always new it.
If its the car in the picture it has the digifant engine. Digifant is electronicaly controlled injection, K-Jet mechanical. Digifant is the more complex system. Its not favoured by enthusisasts as you lose some of the characteristics of the classic golf 8v engine.
For pure ease of maintenance & simplicity, K-Jet wins hands down. Digifant is a complex beasty, and has to be setup just so otherwise you end up with poor performance, economy and throttle lag.
I had a Digifant which had all that from the start, and here I am nearly 2 years later and I still haven't sorted the poor economy! I've sorted the performance & lag issues, but only getting 120 miles to 20 of fuel is driving me absolutly mental ah tell thee
20 of fuel at (nearly) 5 a gallon = 4 ish gallons, 120 miles on 4 gallons is 30 mpg. That's not too bad for an old GTI, is it? I average 26mpg over a tankful.
That's what I would expect for a car of that age & performance, what did VW claim that they should do?
My digi has ran perfectly for nearly the past 18mths i've owned it. It's only recenty I've noticed it seems a little down on power and idle seems a little lumpy. I've cleaned the ISv but I suspect the TB could do with a good clean. I was cleaning up the spare inlet mani I bought last night and noticed how dirty the TB gets inside,
ermm.... just have to get the calculator out the manufacturers spec for the 1.8 8v digifant(82kW) = 36.2mpg @ 75mph aacts and for a 1.8 8 valve k-jetronic(79kW) = 33.6mpg @ 75mph aacts and for a 1.8 16v k jet(102kW) = 34.8mpg @ 75mph aacts and just out f interest it says the syncro = 31.4mpg @ 75mph aacts so theres a difference but not a very big one
