how many throttle bodies? if your talking itb's then kjet or motronic will be no good anyway.

you havent convinced me at all, kjet is great.

basically if your car is on kjet, run the abf on kjet, if its on digifant, run it on motronic (i did say i couldnt remember what its called!).

besides my dad could have yours any day of the week

It's an 88E Golf GTI 8V.  It'll be on Digifant, unless it's a real oddity.

To fit K-Jet on an ABF you'd need to change the fuel pump and source the metering head and all the fuel lines etc. 

All that to get an inferior injection system.  You also need to consider that the cone for the plate-meter provides the 'map' for the engine's fueling and is shaped for the specific engine - much like a carb you don't know when the fueling is right.  Running the wrong cone for the size of engine won't improve running.

To fit an ABF with standard Motronic management you can re-use the Digifant pump and lines to the fuel rail, sort out the wiring that comes out of the donor car and away you go.

The Toledo plan outlined in my initial post wins, easily.
Just because you're offended doesn't make you right.

indeed it does, but only because its a digi to start with, unfortunately your kjet is crap statement is not so accurate.  :afro:

Sorry, but aside from dicking about with my words, I don't think you've actually given any description or valid argument that demonstrates how K-Jet is superior to Motronic.

I'm waiting for it.....

of course i have, read through what i said in the last posts

in summary
kjet is more responsive on the throttle
kjet is simpler and cheaper to setup
kjet is just as fuel efficient
kjet has been proven up to 200bhp, at which point your gonna want to turbo or throttle body the engine anyway
kjet is great out the box, you dont need chips to make it work properly

the only drawback i can see is as you said the fuel map is compromised, but in the real world this is a tiny difference.

anyway im not proving its better, im proving its not 'crap' as you have said, but in my opinion it is better.

look at the kjet 8v vs digifant 8v
