1.8 8v turbo technics HELLLLLLLP please
i've recently purchased an 83 tintop 1.8 8v with a large turbo strapped to it
i bought the car with an apparant poor idle fault which i didn't think would be too hard to sort
upon getting the car back to my workshop i found it had a massive split in a boost pipe, new pipe on problem solved car runs mint and idles perfect, now this is where the headache starts, i can't seem to find any info at all on base settings such as ignition timing, boost pressure, fuelling ect…
the car runs perfect up to the point of boost then coughs farts pinks and holds back, so i'd really appreciate it if someone with some background knowlege on this 80's conversion could help me out, ta

is there any way i can find out if the distributor and vac unit are correct bacause they both look standard gti to me, the metering head looks non vag ie ford rs turbo or volvo turbo, i had to change the plugs coz they were wrong, some warm up reg details would be good as would fuel pressures.
i know i sound like a clueless pain in the arse but there's nothing worse than sorting out other people's failed attempts when you've just bought a car that doesn't have any history to it whatsoever

Thats the nature of Mk1 Golfs though, or for any older/modified car really.

Yep, got the same but The Plugs are BP7 ES.
Have you got a pic of the setup that you could put up here.
stupiddog is yours an original mk1 conversion or taken from a mk2.
Im trying to figuare out how relavant the VW and Turbo Numbers are.
Mine is VW5 and TT049

Are they the plugs that it states on the plate or what you are running?

hi mk1turbo as i said i don't have a plate with any settings on, the plugs are just what ngk recommended for the setup
Sorry. Where did you get the TT034 then? Can you shed some light on what this number is?
Strange NGK didnt recommend the plugs that tt specify or have you been recommended these as you cant get BP7 ES anymore.

i've had a closer look at the fuelling system today and found that it's recently had a filler neck so i've had a look in the tank and low and behold shite loads of rust and other crap not to mention the fact that the injectors are stuck open to the point where everytime you operate the fuel pump the injectors just pour fuel in without the car running so i'm presuming the metering head is also knackered.
do you know if the injectors and metering head and fuel pump are just standard gti on the TT models or different.
one other thing i've noticed is that there's no in-tank pump just an external one, do your TT mk1's also have this setup
if anyone has any engine bay pics this may help with my quest cheers guys

Hi,
Mines and original conversion in a 1986 Mk2, just for clarity I also have a MK1 Cabrio but it's not an 8v Turbo

Apparently the tt metering head will have been machined but i dont know how true this is turbtechnicsmk1 will be able to answer this if he ever logs on.
The metering head you will be able to completly strip down, clean and rebuild. I did it to a 1600 had it chemicaly cleaned and repainted. It looked brand new.
The rust in your tank will have had a major effect on the running and probs buggered up the whole of your fuel system. New tanks are available from GSF as well as Filler neck at a good price. I know a guy who has just bought both of these items for a total of around £120.
We ought to have a sticky thread / register on who owns Turbo Technics converted cars. Would be nice to find out how many are still around. Also Turbtechnicsmk1 might cream his pants over them.

just had a look at some engine bay pics of other TT mk1's and they all seem to have the turbo inlet on the gearbox side not on the timing belt side as on mine, just getting a bit worried now that it's someone's failed attempt at a turbo conversion
