Cordoba SX 1.8 16v

[wicca]

Hi

Does anyone know where to obtain info about the ADL engine???
I am particularly interested in as to whether the head is like the KR one (better inlet flow, worse exhaust) or like the ABF one ( worse inlet, better exhaust)

also quite interested about cam's ? what type are they?

Can I fit 268 schricks or 276's - what will work better and what gains do I expect?? I use the car as a daily driver in heavy traffic

Oh and some reliability question ..... My car has done 270 000kms and gives the ABF (in a Golf) a very strong fight no oil cons over 10 000 km

another strange thing about performance - ABF is said to have more torque and good power low down but a second gear rolling start from 2'000 rpm proves that wrong !!! I gain about a metre till 4500 - 5000 and then I loose 3 meters (that;s in second gear) to 7000

I am yet to change the fuel pump - it is on the way out ....and there is a slight hesitation sometimes above 5000 rpm

Never had a better car in my life


Pic's soon and sorry, greetings from bulgaria

i have had adl in an ibiza and now run an abf powered cordoba,the difference i have is at top end the cordoba reaches better top speed,and is slightly quicker getting there,not a great deal in it.
on the rolling road the ibiza had 145 bhp the cordoba has 157 bhp,torque figures i can't remember,but can find them if you are interested

1.8 16v Cordy SX? Blimey, don't think we got those over here in the UK.

Anyways, i'm sure I recall reading somewhere that an ADL was basically a KR with Digifant management - all KR applications used K-Jetronic mechanical injection as far as I know. Happy to be proven wrong by someone with ETKA in front of them tho

Yes I thought as you did - but got totally confused not so long ago - see, the KR uses a very strange head cover gasket the head and cover have grooves to accept some sort of bulges in it whereas ADL's is like the ABF's - found that the hard way

I have heard of three types of manifolds (inlets) - 42 45 50 mm.......and two types of exhaust manifolds - 4 into one - and 4-2-1
Got confused already??? Me too
There is a significant difference between a KR head and an ABF one

where does the ADL belong????

not that it matters much to me - I love my car - SACHS -30mm susp - body coloured bumpers spoiler and sideskirts , and oh I am still drooling when I see my car - OZ F1 grey 7x15s......

Will look for more go next summer - still choosing the best way to achieve it ....

PS. got an FK Auto cone filter - when the thing comes on-cam at 4000rpm sharp - the noise is unbelievable - I like the looks on BMW, Astra drivers, and rececookers...there are about 6 SX in total (only one ABF az far az I know) in Bulgaria

how come 145 ??? It is rated at 130brake???the adl....

they are slightly better than the book states,it had done 80km i think,plus i had a sheilded inductuion kit,cold air feed and a straight through exhaust without the cat.

I am w/o cat as well - I can have a custom made 4 into one but don't know how long the branches should be

I've seen different designs - and don't know which is best for a relatively std car

 

[WeeJase]

ask robT he has a tubular manifold on his ,i'm not sure but i think its 4-1 ,try the search button he has commented on it before

LOL, yeah, VW engine codes are funny old things aren't they? Some changes to a particular engine seem to warrant a new code, whereas others do not.

I tend to dabble in older 8v motors, if you want to see variety consider how many different variants of the DX motor there are - how about non-hydraulic or hydraulic tappets, regular or air-shrouded injectors, oil-air or oil-water-air oil coolers, and so it goes on... And that's before you get on to stuff like manifolds, there are several exhaust manifolds for a DX motor that I know of...

BTW - it's not uncommon for VAG motors to put out power figures a little over "book" - but a little tweakery can help improve matters too

 

[cordobabrendy]

my abf engine broke a cam, tappet,belt,pully etc and ended up junking it and going for a kr head with kr cams etc, every item in the head was vw kr parts except for head bolts and the kr rocker gasket is indeed different beside the abf item.

 

[wicca]

There are other differences mate.....

inlet ports are bigger on the KR , exhaust are smaller .......
I reckon the cams are different , too .....
Not that it matters much

I have read somewhere (don't remember where) that ABF flies with an early KR inlet manifold that is ( apparently from a KR w/o a cat) 50mm...... as to your 45mm item.

 

[cordobabrendy]

physically they are, the rears of the lobes are narrower but all in all they perform very similarly. flow job is next on the cards for moi!

 

[wicca]

I am considering lightening and balancing of flywheel and crank, mild port & polish (DIY), cold air induction (DIY), and I'm yet to choose 268s or 276 Schrichks......The last is a very tough decision as I do a lot of downtown driving and need more lowdown torque....rather than top power
280mm G60 discs and calipers are on the way as well as braided hoses....Need the braking power

 

[wicca]

Help......



my car i sick...........went to the local dragraces last weekend.......
no power after 5000 rpm..... a silly mk1 GTI 1.8 had a car's lenght all through........
I made a near perfect start and had 1/2 a car before changing to second.....
I am totally gutted
'new spark plugs , distributor cap, car runs fine before reaching operating temp, after that doesn't want to rev .... one possible cause is the FK filter I use - heat soaking???? I have no idea

 

[cordobabrendy]

your not missing are you? i left a lead off mine when i wsas replacing my plugs, car starts and idles fine but theres not upper revs power. as soon as i put lead back on, it revved freely.

 

[wicca]

no, mate....

It's down to a knock sensor failure - got the car to my friends garage to check for error codes and a message appeared "knock sensor - no signal" It has been erased but I am sure it will appear again
Need to change it ASAP....



Car runs fine but this is the second time it's done it.....

what exactly do you mean straight through exhaust???

 

[cordobabrendy]

no cat baffle to slow down exhaust gases, some will arue that it makes no difference while others tell you that it adds hp.

 

[wicca]

Oh I had that removed long time ago
yes it makes a bit of difference all through the rev range - I think the greatest benefit is right above idle speed and top end.power.
I was thinking of removing the middle exhaust but was told the car would be far too noisy....... I am saving up for a complete exhaust system (tailor made) including 4 to 1 mani , 2 1/2 inch all the way.

 

[WeeJase]

i had a centre pipe with no silencing,and it drove me mad,far too noisy and made little difference to performance,probably non at all.
