I think perhaps you should...

Happy days! Replaced the pump and all is well, in that department anyway.

Now I 'just' need to get it set up properly.....

markwix · 27th September 09, 12:29

A thought: I could not it seems get hold of a new gti distributor as VW say it is no longer available, so I am using one from a 1991 1.8 driver. Could this be part of the problem or is it no different from the gti dizzy.

Can anyone tell me where I can get a new vac advance gti dizzy?

Mike_H · 28th September 09, 19:31

GSF or ECP might do a reconditioned one. Otherwise, you're out of luck. You should be able to find a decent 2nd hand one on the scirocco register or Mk1 golf sites.

Injection ones and carb ones are different part numbers. I don't know how different the advance curves are.

markwix · 3rd October 09, 15:45

Right, I have borrowed a digital timing light to set things up as mrhillclimber suggests.

The plugs are the cooler running type.

Strange thing about the pinking; From cold it will rev right out, no pinking, but when its warm and the cam comes in about 4000 the pinking returns. This would suggest it is running out of fuel??

I have increased the fuel pressure via the WUR, but not set up with guages yet. I have been told there is another way to increase the pressure by shimming the bolt that looks like a 17mm plug on the injection manifold body. Anyone know if this works?

if you have increased the pressure at WUR all you have done if made the mixture more lean
you need to set the presure with the guage and set it when it is up to temp
and set it between 3.45 to 3.75 bar as a starting piont the lower the pressure the richer the mixture
3.4bar is probably as low as you will need to go

System pressure shoud be about 5 bar and is best left at that and should only be alterd
if it is low

would be better getting this set up on a rolling road before you melt some thing

Good advice! I will quit stumbling around in the dark and put my hand in my pocket for a RR session.

Stealth have said they can do it but they are quite a trek from suffolk. Any recomendations of an RR more local?

Mike_H · 4th October 09, 18:28

You need fuel pressure gauges really, or a rolling road session.

markwix · 5th October 09, 15:06

I have had a look on ebay for gauges and watched the handy tutorial on you tube, but can anyone tell me exactly what I need and ideally where to get them from!?

MUSHY 16V · 5th October 09, 15:53

Where are you based? Maybe there's someone local who can lend you one? Kjet has odd fittings, which most of the modern kits don't contain.

markwix · 6th October 09, 19:42

I'm in Bury St Edmunds, Suffolk if any of you kind folk can help!

The tutorial on you tube appears to suggest one does shim the 'plug' on the injection manifold to increase pressure to the injectors. I was informed that this was definately done on the original k-jet when the engine was in the slick 50 mk1.

Interestingly the original set up also used a Capri 2.8 WUR instead of the 16v unit. Anyone heard of this before? Not that this is my intention, just curious!

Mike_H · 6th October 09, 19:45

Interesting - hadn't heard of a capri WUR trick. I guess the engine might have pre-dated the 16v WUR. Did the capri one have a screw in the back, or the plunger type adjuster on the front like an 8v?

markwix · 6th October 09, 20:08

Pre-dating the 16V WUR was my guess also, as I am sure they would have used OEM if possible.

I got the engine minus all ancillaries so never saw the capri unit.

Capri WUR. Looks very similar to me. Looks as though it may adjust like the 16v unit?

Mike_H · 7th October 09, 07:48

Hmm - from the first pic, it looks like it's got a vac line on it - so rising rate.

markwix · 13th October 09, 20:09

Right, much as I love this car I need to concentrate on my mk1 and need a passat estate or similar to use daily. I will post a proper ad in classifieds at the weekend, but if anyone fancies;

Mk2 gti 1984 (A) 3 dr. Mars red, never welded. Lowered on G60 steels, otherwise standard. Slick 50 8v on k-jet that needs setting up properly. 16v box. Tax & test.

Make me an offer before i change my mind again!
