KJET/ABF Conversion

[miggs2002]

i did the hybrid conversion to my mk2 as i kept killing my KR engines, i didn't fit the loom as i didn't buy it with the engine, i had never had an engine last more than 8k until i fitted the ABF, i never got oil pissing down the breather with the ABF and i did the hybrid way as it seemed the easiest and best option for tweaking further down the line, that was the only engine i removed form my mk2 in full working order after 15k miles happily driving it hard, i fitted a VR after the ABF and other than noise and top end speed they were pretty much the same when driven hard, obviously fitting a VR is a full engine loom job and i have done many conversions before and after, infact i just converted a fellow members mk2 1.6 to the mk2 2.0 gti engine, that was a full tank swap as well as the engine and loom so i didn't do the hybrid cos i was "scared" of wires, i was just commenting from personal experience, i never got any of the engines rolling roaded so no idea what actual power they were running but was told that it felt a lot quicker and more torquey than the KR, it also made a lot more mpg on motorway runs too, again i don't know what a digi controlled ABF would have one in the same car

If K jet is better why have i had to replace pistons on K jeted ABF's  but never on an ABF running digi 3.

I think this is why they have to run them rich. My other post regarding KR tuning where CO was 5-6% was on the ABF. The kjet can't really fuel it properly without lots of adjustment.

Wow - you're seriously in fear of full stops, aren't you?!

was told that it felt a lot quicker and more torquey than the KR

That's the throttle response on K-Jet and someone with a new engine who's been told it's 'better'.

it also made a lot more mpg on motorway runs too, again i don't know what a digi controlled ABF would have one in the same car

DannyP's Digi ABF got over 40MPG on motorway runs, in a Syncro.

K-jet was great in 1983 but now it is licking the window of the tard bus, reduced to a dribbling wreck of its former self.

Cue the Picture


Why wreck a good ABF with it?

can you not read it without full stops?? you must be a special person then.....
i was told by someone that had been in the passenger seat of mine before that the ABF felt quicker than the KR from the passenger seat.......
and yes mine got mid 40's too, the KR got early 30 at best before that.....

sorry for any inconvenience

No, thankfully I'm pretty capable at reading, but you seem to be posting with about the same intelligence of a K-Jet metering head, which is disrespectful to others reading your posts.  If you know you're posting rubbish it makes it worse.

It's good you're able to provide hard evidence about the performance of your ABF from a passenger's seat of the pants reaction.  Pretty accurate stuff.

Tell us some of the stories you've heard down the pub.  I bet they're riveting.

i wouldn't want to offend your audience by telling them the things i've heard about you, but thanks for the offer, i'm pretty confident that i've had more experience than you of KR and ABF engines, but you obviously know better as your the cleverest person in the VW world, it's idiots like you that make the forums hard work, people trying to offer knowledge from experience and they get met with people that know better from what they have read on the net

OoooOOOOooooh - veiled threats, how exciting.  DO tell us some of the things you've heard about me.  They're ALWAYS thrilling.

Glad you're so confident in your nolidge, because it comes across as subjective nonsense.

Maybe you have ANYTHING to back up all your seat of the pants info about how ABFs run better on K-Jet?

It's people like you who make forums SUCH hard work to read due to your moronic grammarless posting style.

Anyway - back to the stories about me....

nout wrong with a kjet abf, you guys obviously didnt have them set them up properly. if you have a kr with everything in order, theres no point removing dash centre console etc to get at wiring, just drop it in and set it up. Ive never suffered holes in pistons etc, and ive had kr,9a and abf. Only the tiniest bit of pinking on the hottest day of the year was my only gripe. Dont get me wrong ive never been in a digi abf mk2, but i went from 66hp 1.3 to 159hp kjet abf, sure it seemed fast, but soon got used to it. i reckon the extra smoothness and mpg would soon be forgotten in a digi. never had a problem with the kjet, though i see many a digi thread, with all sorts of problems. could be said its over engineering compared to kjet as the gains are minimal. and as for going standalone?! on a £200 engine?? pure madness spending that sort of money on an n/a sub 200hp engine imo!! plug and play digi if you can be arsed with doing a full on swap job (dont forget to do 02a and hydro clutch, no slacking on cheap cable clutch) or chuck it in in a morning if you've already got a kr thats fine otherwise
