@ lowmk1.  who has quoted you 2.k for an abf conversion?  surely on your kr engine its just a change of block and head, and using your existing kjet injection. plug and play!
the price of the block and head. £400 max

Its totally different injection and needs all the loom, lambda sensor and air flow metering sorting out. Not a big job, but definitely not a £400 job either.

never going to get it done for that price if you want the conversion done right.  also the k jet should be ripped off and sold to someone else. it is one of the advantages of the ABF and k jet is just hasstel

the complete ABF itself or donor car  £250 - £500.

prepareing enigne to fit.

new clutch      £60 - £100
new cambelt kit         £60
new HT leads            £45
new plugs                 £10
new dizzy cap           £5
new oil filter             £2.50
new acsessory belt     £8
new exhaust studs      £8
new exhaust nuts        £2
new exhaust gaskets    £4

likely new cranckshaft position sensor £50

( also on cheep engine's  on the engine or it's history  potentialy  headgasket, tappets & valve guides may be required )

prepareing car for enigne.

replace engine mounts.  £70
new radiator                 £50

£50 for oil, antifreeze and the odd clip and stuff

thats £450 based on those tough prices,  say you get a good deal on a donor car  £700 + time  to do it properly yourself.

for eaxmple if i was doing ABF conversion for someone else that lot and anything else looking sub optimal would get changed.   i've had enough muppets wave engines at me askign to fit them as they are. and a few times i was daft enough to fit them  and it just ain't worth it.
all the VW's have gone bar 1.

agreed abf with abf managmnet is literally fit & forget, if you do it right in the 1st place replacing bits that should be replaced. To that list I would add new ECU relay, coolant temp sensor and vacuum lines, probably lambda probe as well.  Main stumbling block with the abf managment is the lambda, shouldnt cost too much to get a boss welded in, even if zaust is on the car my mate got his done by the phirm about a week after.

That plus the immobilisor if its post 95, but if you get the matching key, ecu, transponder box & ring from the donor then you should be ok.  My mates key wasnt coded to the key for some reason, so he had to get it transported to VW to have another key cut & coded.  Didnt cost that much either, but some dealers may not be so willing to do it on an engine conversion ideally we needed the V5 from the donor car to proove we didnt steal it :grin:

k-jet on the other hand is cheap and easy, but it takes a lot more messing about to get it running right good replacement parts are getting hard to find, and new parts are expensive compared to most ABF bits that are likely to go wrong.  Plus if you want em tuned they're starting to get a bit long in the tooth so finding guys who know how to tweak em right isnt so easy, that and if you wanna go big power its much easier to do it with abf managmnet.

If you do it yourself you'll know so much about your car that you'll never need to use a mechanic again. Think about having a go!

Agreed there Dave, for the amount of money you will spend on a mechanic to do it for you, you can rent a garage and buy all the tools you'll ever need and have cash spare!  :wink:

But for the purest engine experience, displacement has no replacement. All other methods are simply attempts to artificially recreate the benefits of displacement.

is it possible to get 200bhp out of the abf without to much effort

One of my old ABF lumps (now sitting in storage awaiting re-shelling) managed to put down 208.8 at the flywheel and that was still N/A. My current one (in the car) will be 260ish when I have the supercharger fitted along with a few other little tricks but is pushing 188 at present.

208.8 was achieved with quite a few mods but ultimately only cost me £400 to get it there and a lot of my time! For me it is definately a case of having the workshop skill & access to the right places and people  :wink:

but you can run it on the k-jet if wished. and never mentioned running digi 3 in the original post. believe toyotec saw good figures on that combo.

im still looking into it on mine.  but as said, to do properly, and properly prep an unknown engine costs. as i found out on my 2.0 conversion!

Right, I just got back from driving a mk2 with a vr6 installed by TSR...

Spec is below:

2.9 VR6 rebuilt by TSR
Gas flowed and polished throttle body and inlet manifold
de-cat
Also the car had struts and eibach anti roll bars etc

Verdict:
Car was quite nippy but I was not overly impressed! :shocked:
The owner says it was a 200bhp motor but i reckon it was an inflated figure from TSR.
One thing that did surprise me was that the cars handling was not as bad as people make VR conversions to be (this one was on existing mk2 subframe, 4stud). Was quite responsive around the bends  :smiley:

I can honestly say, I had a much better journey home in the valver as she hit 3.5 k on the rev meter  :cool:
