Thinking of putting an abf into the mk 2 keeping kjet is it case just buying block and head and bolting the kjet stuff to it.
Also what manifold did people use
Cheers

Without being snide, this has been covered in some depth previously. Personally I would say buy a donor car complete and fit the whole EFi setup.
Toyotec has made a very good guide.

Better to fit the complete setup.

I disagree. My Kjet abf made 160bhp and was spot on for years. The Kjet is the only thing that was good! H/g went, crank keyway failed etc etc but the Kjet side of things was fine. If you are running a fine Kjet setup then just drop the engine in, it's a weekends work to do a nice job of it. Wiring and fuelling swap etc just isn't worth it for the marginal gains. I was bored within 5 minutes of it anyways, so now it's 223bhp from an agu k03s.

So does an abf on proper management, except it also returns 40mpg and doesn't need setting up every 5 minutes. Fit it properly or don't bother in my opinion. Easy swap.
-
It's also nice to have an old shed that runs spot on all the time and always starts instantly.
Rather than the revs plummeting at junctions and cutting out when cold
-
easiest way is to bolt the abf bottom end to existing k-jet head.
anybody who complains about kjet just cant set them up really :p
-
yeah and im sure an abf management wouldn't be 100% reliable forever more anyway. I mean how many k jet equipped cars do you see stranded at the roadside?

But how many k jet equipped cars do you see? :smiley:
I suppose it depends on what you have to start with I'm midway an abf conversion on a a late ce1 8v digi and I'm using the abf management. If my car had been a 16v I'm not sure i wouldn't have retained k jet.

Kjet was fitted to fords from about 83 to 91, onion XR2/3 etc etc. With a gas analyser and some patience can be set up to be quite effective, although efi is much better and reliable for longer periods.

You missed the point, there was no plummeting revs, no dodgey idle, it was setup by someone who knows what they're doing, which you mightn't be fortunate to access. If mateys kr runs sweet then just swap engine, but sure if components aren't functioning correctly and it runs crap then maybe think about full swap. I never got 40 mpg because I put it in there to thrash, which the Kjet loved every day. I've done some work on a mates an mk2 and he never gets to drive it because of digi problems. Just look at the threads posted on this forum and cgti about digi problems!! Over engineering for little or no gain onthese engines imo. I wouldn't tell you to run a 20vt on Kjet, but an abf, just do it. As said, if you want something 'rapid' you'll go 20vt eventually anyways.
-
a 20vt is far from rapid. you aint tried a 900hp cossie by any chance? and once you been on rita at alton towers then nothing will ever come close lol.

Rita? Does she work there? :grin:
-
yeah and she 1 fast lady lol. oblivion is quite mad to.

My jet makes a 900bhp cossie look like its going backwards.. But considering we are talking golfs (given the website URL) then a Kjet abf is just as quick if not quicker than a digi. Good tuners can do a wur mod to sneak a bit more fuelling, not possible on digi. Kjet is known as more aggressive delivery too. Speak to people who have a good understanding of Kjet and they'll tell u it's perfectly fine for a circa 150bhp engine...

Kjet designed with performance in mind
Digifart designed with economy in mind
:)

Exactly. who puts a 2.0 16v in their golf for economy?!

You are wrong.
K-jet - designed to improve on a carb
Digifant - designed to improve on earlier injection systems like K-Jet.
Digi 3.2 will give you the most reliable, powerful and economic solution vs K-Jet. Why? Because it controls the systems on the motor in a more advanced and closed-loop manner. A couple of examples:
Knock-control - two sensors, which will allow you to advance the spark more to get more power if you have better fuel
Lambda, MAP sensor and throttle-position-sensor - measures the burnt mixture, allowing the vehicle to manage the amount of fuel going in, to suit WOT applications, cruising and start up etc etc
The K-jet has a shaped bowl and a flap, which controls the amount of fuel misted and a warm up switch to enrich the mixture.
It is primitive and prone to failure.
Solid state components last much longer and are more reliable. They can also respond faster.
Trying to suggest that the injection system fitted to the G3 16V GTI is 'for economy' is a stupid suggestion.
A properly built and managed high performance motor should be high economy too when it's not being thrashed. That's what EFI allows you to do.
-
Jeez you took that bad!
-
Better than K-Jet would though.

If u don't know what you're doing run it on digi, and if luck is behind u it might work with no problems. However it prob wont and you'll be on here everyday asking for help. If your kr runs fine then just swap the lump..job done. Unless you want to change loom and fuel system etc as well as the engine then go for it with digi. I've had an abf on Kjet and I'd recommend it to anyone. I used to smoke people up on a daily basis. I've got bored of 159bhp and gone 20vt since, and I see some folk are still struggling to get their digi running right, they never get to enjoy it!! Mines been in and out in that time. Yeah on paper digi is far superior, in practical terms however its over engineering, and a lot more hassle for little or no gain. You'll have a smoother more efficient mk2, but you'll prob get done by Kjet abf's (if your digi ever leaves the garage that is). I speak from experience as I've had one myself, am an electrician, and am constantly getting asked to look at a mates poor performing digi abf.
-
whichever way you look at it the k jet is a less complex and more reliable system. no crank sensor/ maf/tps/lambda to give trouble. just run some fuel cleaner through it. make sure all hoses are sound and get it tuned. and it will run for a long time without bother. who cares if its slightly less economical. at least you know it will always get you where you want to go.
-
Old 8v digi yes, lots. Old k jet there's a thread on here every week without fail. All I did to my digi abf was fit a lamda sensor last week after a year of running fine without it plus a year of that engine sat in the garden. There's nothing to set up.
Where are all these poor running digi 3.2 abf posts?
-
I've seen many on here and on Cgti. Kjet is perfectly fine,Its just that not many people know how it works or how to tune it unfortunately..remember its made by Bosch, fitted to many cars of various makes at the time, and was the best thing at the time. This is still an old car remember, so sure if you had a 1.3 and needed a complete donor Id go mk3 full setup and 'modernise' it, but ffs he's got a kr already, that possibly runs absolutely fine, so for what it is I'd just slap The engine in an have the fun from it. Obviously if going 20vt or more, use a system that's more upto date and developed with the engine..
-
when the k jet was the age that digi 3.2 is now there would never have been any bother with it. and I don't recall seeing lots of threads about faulty k jets???
