This is a mod i just did for my TTS & BTS sensrs. Please dont ask what coolant flange it is as i forgot . Ordered it planning on using it on the turbo ABA but was the wrong one so kept it. That was a year ago. Anyway.....

You will need to fill in the 2 lower sensor ports as the flange sits close to the head.

This s the flange. sorry for the bad pic. it was late and i just wanted t get it done.

finished producted..........

i think i popped my cars 'cherry'. for some reason, i got on the hwy going to work, and it seemed a hellova lot faster. i mean..you know your car, every rattle and bump. either i gained or freed up about 10 ponies. thoughts? i checked to see if i snapped an axle or something, all seems well.

[TurboXpert]

I blew the tranny lastnite in the middle of replacing it. Im defintely loving every minute. I have no traction n 1st. & 2nd.

The hex isnt flush enough. tried that. They have to be filled

[OhioBenz]

i wasnt talking about OEM plugs.
I forget what size plugs I put in, but they dont leak and are nice & flush.
US versions can be purchased in a short length....

[rychas1]

104 hp @ 6100, 104 tq @ 4300...2nd gear @ 6800 pull. not bad for a 3spd

ill post sheet later.

can't you just put the allens in and grind the top off of them flush or does it comprimise the sealing surface for the flange?

[OhioBenz]

those OEM are face sealing plugs, replace them with the short NPT plugs....

It sits right up against the head. unless the plug counter sinks it wont work.

At first I thought he just spoke poor english which is not uncommon, but after reading all his other posts, I smell a troll.

[OhioBenz]

yeah, like from Nigeria...willing to pay with bank check or wire transfer - of course for more than the selling price so you can send the balance to his relative....

exactly I thought he was using NPT plugs and they still stuck out.

[OhioBenz]

there's a short (flush) NPT

Wondering if someone can lend some help as i am at my wit's end with this problem.................

Specs: 16v 2.0L running on CE1 digi2.

The car cuts out often and wont start back up. I narrowed it down to it not getting any spark from the coil. Ive changed the obvious things (coil, ing. mod. etc.......) and it still dies on me. It also bucks at cruising speed. I watch my A/F guage hit lean everytime it bucks. For some reason the guage ist cycling (yes it is hooked up correctly) it will cycle for a bit then stick on rich for a bit But my main problem is it cutting out on me. Ive ran through the entire harness for cracked or broken wires, ive opened the computer to make sure nothing was fried. Ive checked it all it seems and yet im still having the problem. Also while the ign. is on i plug and unplug the ign. module while the coil wire is off the dis (grounding of the valvecover). Its lie now when i plug and unplug it a few times till it stops sparking only then it will start.

My question is does the ign switch play a part in the coil having spark? What else do i need to be checking? what will cause the the coil not to have spark? All grounds are good including the ground strap by the coil.

In the 6 yrs ive been on vortex this is actually the frst time ive asked for help so you know im stumped and this is coming from a person that makes his living building VW's. Ive been at this for almost a month. and ive had to tow the car home 10x's this past month

any help would be appreciated

[Andy Bro]

I had a similar problem with my car, one of the leads for the ignition module had pushed itself back out of the connector and was making intermettent contact.

[OhioBenz]

yes weve had a bad ignition switch do something similar in a digi-2 8v

you probly know the trick in pulling those - we got pretty good at it

[rychas1]

this might also be the dreaded MAF vibration issue. basically the connector vibrates and loses contact with the MAF and causes car to either cut fuel (my case, once in a blue moon) or die and not restart (more common). clean and check that connection. because the AF gauge not moving is the sign i get everytime it does that. then .............nothing, o wait power again.

Yep, I've had that too on a Digi2 8v.

[radomang60]

I found the issue. It was a bad and/or wrong ECU. Seem like the previous owner used the wrong ECU. I put in a fferent ECU (from a 90 CE1 Digi2 Golf) and the ar runs great. no more bucking at idle speed. Im hoping it solved the cutting off issues as i havent jumped on the highway yet. *fingers crossed*

[Andy Bro]

I had a similar problem with mine, I actually wound up killing that ECU but when I replaced it some other problems went away, like the fact that it wouldn't rev past 2.5k

[rjvwryder]

do you think i can put a 16 valve in my MKIII i think my tranny will bolt up to that engine? my MKIII has a 2.0 block so its pretty much similar but with a smaller head and the motor mounts are the same i think............

the link above is great if you are doing an ABA-16v combo. If I read your question right - you just want to drop a complete 2.0-16v in??
All you will need from the above link then is the parts that allow you to run the Digi fuel injection - i.e. the fuel rail, injector cups, fpr etc.
Everything else is a bolt-in swap.

dropping a 9A in more complicated because you need to attach a trigger wheel for the crank sensor, etc. (since the Mk III is already Motronic it would not be wise to go back to digi II) not to mention installing an older engine in a later chassis.

[OhioBenz]

yeah - forgot about that...but theres some kits available for that. Has anyone run the motronic on a 16v like that?
Sure would beat having to build a motor/combo if all you want is an EFI 2.0-16v.

[TurboXpert]

thought i'd share a pic or 2 of my baby.

Only issue im having with it now is that it stumbles sometime when its warm and trying to start it. It doesnt happen often and i just shut it off and on, after that its fine.

[rychas1]

im back!!! fresh head and parts. lets go

[GutlessLump]

what do you have now?

[rychas1]

similar setup, just newer head and relaterd gaskets and crap. nothin fancy.
