Right here goes.....
You may all laugh at this but after finding out today from my gorgeous wife that I have a new arrival coming in feb :smiley: :laugh:(and no its not a golf :sad:) )I am looking to keep my costs for tuning the golf down.
I am looking to retain the 1.6 8v gti engine I have but change the camshaft to a fast road/race cam or a g60 one(would this work) but I am unsure as to which one so does anyone have any recommendations?
I also plan on using the eaton m45 supercharger I bought ages ago but would I need to fit 2 head gaskets to lower compression while at the same time I'd prefer to retain the kjet injection system and only change the dizzy ignition system to a megajolt ignition system....(along with some progressively fed nitrous later on)
I have a 2l 8v engine sitting but ultimately want to change that for a 1.8 16v engine with bike carbs etc but for the now I am having to stick with this engine and I have everything for it sitting around.
Has anyone any comments, will it work or is it totally wrong..... :smiley:

Good luck mate! yer gonna need it!

Not worth the hassle / work and expense for the little gains you will see.
K jet will not be anygood, you will need to go standalone managment.

I stand to be corrected here, but I don't think you can turbo or super charge a kjet. :undecided: I don't recall ever seeing a kjet set up like that. kjet has no ECU either does it as it's mechanical injection.

Broadspeed did it in the 80's with a pressured air flap, don't think it worked well to be honest.
Lack of safety if the mixture runs lean is the big issue.

I am just going by what a friend done to his 1.8 8v kjet as he kept it all pretty standard but fitted a turbo. It all seemed to run fine for him but there may have been something else fitted that I cant remember. I do remember him talking about a KSTAR or something though.....

Yes but is the work / expense worth it for a 1.6, the gains will be small

didnt the lancia delta turbo engines run a similar setup to the k-jet?

Very early KE jet I believe or motronic
-
volvo, saab and porsche all had kjet turbo engines, i suppose they just made the flap stiffer :grin:

They also had a very early / primitive form of knock control.

apparently also used in VW, Merc, Ferrari and Ford!

Yes they did but k jet does not work very well with a turbo or supercharger, you need a knock sensor for safety and also some form of boost control.
K-Jetronic (1973–1988)Mechanical fuel injection. The 'K' stands for German: "Kontinuierlich", meaning continuous. This is different from pulsed injection systems, in that the fuel flows continuously from all injectors, whilst the fuel pump pressurises the fuel up to approximately 5 bar (72.5 psi). The air that is taken in is also weighed - to determine the amount of fuel to inject. Commonly called 'Continuous Injection System' (CIS) in the USA. This system has no lambda loop or lambda control. K-Jetronic debuted in the 1973.5 Porsche 911T, and was later installed into a number of Porsche, Mercedes-Benz, Volkswagen Group, Ferrari, BMW, Volvo, Saab and Ford automobiles.

Thats it! Wikipedia :D
this is true, if it was any good, all those company's would use it today.

K jet was ok for the time but things have moved on.

1.6 will take boost
1.6 will take supriseing amount of boost
1.6 easy boost
easy oldskool way is to, strap the airflow assister straight ontop of the inlet manifold and strap a webber to the intake of the charger.
it'll do about 150 bhp before it goes bang

Is much easier to supercharge and engine rather than turbo it?

Not really.
-
imo it massivly depends on the engine really.
some lend themselves to supercharging some lend themselves to turbo, on other ether is a battel

The old RS turbo escorts had K-jet and were turbo, but.. Rarther than K-Jetronic, it was KE-Jetronic, it was still mechanical injection but was helped along with an electronic igntion system. But none the less it did use a flappy flap meter, lol all be it upside down, So yes it can be done but No just dont even bother! :smiley:
