so i am a noob. this site has done amazing things to teach me almost everything i need to know. it has been one of the most useful sites since i've bought my little caddy, so i want to put something back into it.
i bought a turbo and i think all the fittings i need from burn_your_money a long while ago, and i'm just now getting ready to install everything. i read the Bentley manual, and convinced myself i'm ready. and so today i start cleaning everything up and i'm a little confused...
the oil pressure line in the bentley manual looks way different than mine does. and i'm not sure what some of the rubber pieces do.
please forgive my noobness, everything you guys do to help me will be made into a tutorial to help other noobs such as me do this in the future.
here are the goods, excluding the TT downpipe. please share your thoughts!

i'm planning on doing a compression test, and obviously an oil change during the conversion. anything else i should do before i start?
thanks for all your help.

moved this into the IDI section for now... if it gains steam and becomes a good FAQ I'll move it back and link it from the main FAQ.
-
that you very much! i didn't want to put the pics in the thread because i thought they would be bigger on the photo bucket to get a better look. the truck is an 81, it's dark now but i'll check the engine code later to see if it matches up. stupid question perhaps, but what do you mean by compressor? not for an AC?
not pictured is the oil cooler, it's under a newspaper, next in line for cleaning.
-
perfect, thank you. i hadn't heard that phrase yet. you've been a big help already. what is the little bit of electronics on the crank vent tube for?
-
you are the man, Mr. Libby! thank you.
-
anybody have a part # on that bypass hose? just found a slit in it so i can't use it :(
the 1.6 td parts are kind of hard to find in 'merica it seems. everyone looks at me like i'm nuts...
or if Gee-Bee makes a silicone one that would be rad, too.
-
TT downpipe? whaaa
-
The electronics are a little heater in the vent that prevents the formation of ice-crystals due to freezing of the moisture as the pressure drops rapidly going from the positive pressure of the vent tube to the negative pressure of the inlet to the turbo. Wire it for 12 v when ignition is on, fused of course.
This is a stock piece? My vent hose does not have this on my '84 factory TD. It may have been removed though.

mostly just the COLD climates that got the emissions vent heater..

Is the blow off valve on the intake of anyuse or can it be weld shut ?
Thanks,
Hugh

get rid of it. there useless if you want more than 12 psi..
-

i didn't want to learn to weld. seemed like a sound investment!
Libby, thank you again. i got nervous because whenever i saw that piece it has automatic transmission in the description. i probably won't need that heater in sunny CA though.
-
I think the heater one of those things that VW added for a very specific set of circumstances - you would need a climate cold enough that the intake air flash froze the (hot) blowby gasses coming from the engine. It would need to be COLD for that to happen, like 20 below or more.
For the blowoff valve, I think Giles was selling some machined caps that would install in place of the valve thereby sealing off the hole. Another option is to use a newer intake manifold (from a TDI, or even an AAZ) that doesn't have the valve at all.

slight issue. i'm trying to do this project this weekend, but i've run into a hitch.
the oil flange and oil cooler seem to be missing a part. here's what i have:

(http://i689.photobucket.com/albums/vv255/jebmssmith/Turbo%20Project/IMG_20101212_163557.jpg)
isn't there supposed to be a threaded pipe bit that holds it all together? i think it's called a union? and a flange nut. i don't have either. so either does anyone have exact measurements for the union? maybe something i can fabricate at a hardware store? or a part# for ordering wouldn't be terrible either. or how terrible would it be to not run the oil cooler? and no threads on the top of the flange for the oil return line. i guess i could get that piece at the hardware store, too.
-
is the second hole for a sensor?
-
Yes, the oil pressure sensor.
-
perfect, thanks.

You'll need to move your fuel filter from the shock tower to the front fender as the intake tube is a tight fit. You'll have to replace the fuel line with a longer piece but it's not a bad idea on an'81 and especially if you're planning to run bio. Even though you've disabled the blow off valve, you'll still need to run the hose or you will have a big hole. The waste gate should go off @15 psi and will give you a little more oomph.
I'm running a K&N filter on the end of my intake hose and it 's working good. Resist the urge to clean things up by cutting a hole and running some flex pipe to the cowl area; the noise is deafening. Please invest in a decent down pipe. Build one or buy one. 2.5" is a good size. 3" is a ground dragger. The stock cast iron piece is a joke and the old NA system is a crime.
My engine has the oil sensor on the head. I tapped into the second port on the filter adapter for a mechanical gauge. You might consider using a ford oil filter as the clearance to the frame is really tight with the cooler installed. It's the standard PH8-A (fram#) filter. there's also the PH 16 which is a shorter version. Some brands of the V-Dub filter are quite long & could rub. Very happy that I decided to go with a turbo in my caddy. A cop let me go for doing 76 as he couldn't believe that I could actually do it. (I've had it to 95).

i had rain-tray induction on my 81 rabbit.. i loved the sound at idle.. that was the only time i could hear it..

i like where that is headed... i may steal that idea from you, sir.
i'm getting closer, i just need a compression fitting for the oil filter flange to get things rolling... stupid 'merica and not having anything metric...

a shot with the rain tray intake..

and a shot from the side, almost showing where it hooks to the turbo.

no problem sucking in water with that intake?
-
just ordered the well recommended EGT setup from aircraft spruce, a boost controller, boost gauge. had to grab some silly compression fittings and whatnot for the oil line, and ordered all the gaskets i need. getting closer to building it guys... i'm excited!

i live in OREGON! i think if anyone would have problems with rain, if there were gonna be any, i would know about them.
and the filter isnt actually sitting on the floor of the rain tray, its suspended. and that was just a temporary filter in the pic.
it sounded SOO SWEET sitting there idling..
-
I live in Oregon too. I'm using the goofy looking stock rubber intake hose so my K&N fits right up front where your pipe fitting is. There is a baffle beside the radiator that keeps any direct water from entering the system. I had a problem with rain & puddles soaking the alt. belt and making it squeal. I installed a 95 amp alt. and it pulls a bit of power. I ended up making a tin tray that I screwed to the body that protects this area and the problem is gone. Still, with the rain tray intake.; this would seem like the ideal place for it but I had a huge K&N and while it sounds cool at lower speeds, I repeat, it was deafening at speed. Stick your ear next to your wife's Kirby when she vacuums the carpet and you'll know what I mean. Maybe your filter isn't quite as noisy, but that's just my experience.
-
i dont hear any intake noise. but that may be that i have a VNT.
and it may also be because i run nothing but an open downpipe..
i like my cars loud tho. i really wish my rabbit was louder. these vnt turbos are just NOT LOUD at all tho.
