I have a 81 1.6 diesel rabbit. Going to turbo and have some questions.
First what turbos will fit on this manifold?

2Where does the egt go on this?
(http://i33.photobucket.com/albums/d54/vdubin_g60/P1000173.jpg)
3what is this bracket?
(http://i33.photobucket.com/albums/d54/vdubin_g60/P1000174.jpg)
4what are these threads for on the downpipe?
(http://i33.photobucket.com/albums/d54/vdubin_g60/P1000170.jpg)
5What do i use for a gasket in there?

6what does this nipple do in the pic above?
7Is this intake gonna fit it looks small and doesn't have a hole for a bov like others have that i have seen

1)K24, K14, T3, possibly more
2) Near where the turbo mounts, somewhere pre turbo that all the cylinders meet at
3)Holds the intake to the exhaust manifold (I think)
4) There is another bracket that goes there to hold the turbo to the manifold
5) Silicon?? Very little though
6) That goes to the injection pump LDA so you get more fuel under boost. Cap it off or run it to a boost gauge if you don't have a LDA
7) It looks like it will fit. I'm not sure what it is from
-
turn the yellow intake over and takea pic and post it! and same with your other intake so we can see the openings! can give better answer!
thanks Duane

Alternatively, it wouldn't be much work to just make a gasket for that flange/elbow. Just get some gasket paper, cut appropriately, of if the edges are sharp enough, do the hammer on it to cut it thing.
If you don't want the spraypainted yellow manifold, I'd probably be interested in it if it's cheap. :D
-
yar, a manifold without the stupid diverter valve would be preferable in higher boost applications(and sweet on any motor)
and the bracket on the manifold bolts to the downpipe at the two threaded holes you asked about, makes the assembly a little more rigid.
-
the yellow manifold and the silver one are the same. i took the yellow off. heres a pic of the holes.
(http://i33.photobucket.com/albums/d54/vdubin_g60/P1000168.jpg)
im going to see if the holes match up with an old na intake mani
How much fuel do you need for a k24/t3. Ive been turning the fuel up but would i have to go into the pump timing? na pump
which is better/cheaper to find. what size t3 is the same as a k24.
Thanks for the help so far
-
thats a 1.9 intake "D" ports
Duane
-
will it fit? on the 1.6
-
yep! pretty sure!
Duane
-
i'll double check tomarrow :D

How much fuel do you need for a k24/t3. Ive been turning the fuel up but would i have to go into the pump timing? na pump
also what can a guy use for the oil lines? tap on top of the oil filter and on the oil pan-anywhere?
where can i find a hose/elbow from the turbo to the intake manifold?
so all i need is a oil filter housing tapped, tap the oil pan. find a turbo
piping for an intercooler and an intercooler. oil lines. egt probe and gauge boost gauge anything im forgeting?
would i need a intercooler right away if i run low boost?
-
Get hose coupler from auto parts store ,they should sell you a 2"radiator hose for a truck.Ive got some and mates up perfect.The one i get has one 90 deg. elbow and is long enough to make enough couplers for a whole charge pipe system for your intercooler.Or theres feebay! :D
-
Its a 1.9 TD manifold and yeha it will fit onto 1.6 no problem.... 1.9 manifolds were the ones that came without the BOV cut out.
Dont u wana add Turbo pistons and oil squirters??? its just sumdrilling and fixing!
-
I dont think that im gonna run a lot of boost and i already had the head off not too long ago for a fresh head gasket
-
it looks like someone did some porting on that intake. the inside is usually pretty rough and grainey.
the BOV is kinda useless if you ask me. the wastegate should be fine at regulating boost unless it gets stuck from not using it.
-
i did the porting there was a lot of black soot in it.
-
some questions i still have

where can i find a new or rebuild t3 for a good price and what size is best
what is a good/cheap egt probe and gauge to use that others are happy with?
-
ya the bracket bolts to the downpipe holes
-
ya the bracket bolts to the downpipe holes
does anyone know what thread size fits in the holes?

Everyone's saying the 1.9 intake with the "D" ports will fit a 1.6 head.......yes, it will physically bolt up, but the 1.6 head has oval intake ports.....you will need to enlarge your 1.6 ports to match. I have no idea if there's enough meat there to do that. Seems to me there is, I think I remember a few guys on this forum doing just that.

well, it will work!If your not concerned with turbulence at the intake port,then theres no problem.The charge is pressurized anyway,so i wouldnt think that a free flowing transition is as important.Maybe if it were an NA,but the turbulence is slowed down when more air tries to take up the space in the turbulence with the pressure.On a NA gasser i would think it would be most important, as the velocity is more intense(needs smoother tract).This is not tested theory,just a theory. :DIm using a chopped alh manifold on my 1.6.One bonus is you dont have to worry about the bov :)
-
I already had my head machined so i dont think i will have them port matched. i think it would be fine just not the best.

You can advance your pump to 1.00mm. Then turn up fuel. I would NOT do this unless you have you EGT gauge installed.
also what can a guy use for the oil lines? tap on top of the oil filter and on the oil pan-anywhere?
What is best is to take the oil lines and oil filter mount from a TD. Otherwise you can bend your own lines out of mild steel tubing.
so all i need is a oil filter housing tapped, tap the oil pan. find a turbo
piping for an intercooler and an intercooler. oil lines. egt probe and gauge boost gauge anything im forgeting?
Nope - sounds like a plan.
would i need a intercooler right away if i run low boost?
Yes, it's highly advisable - do it right, do it once..
where can i find a new or rebuild t3 for a good price and what size is best
I would suggest a T2 to K14 instead.

Search Ebay

why do you say that. t3 too much lag or ??????
i have a t3 that needs to be rebuilt or should i get this?

thanks for the help
-
The T2 or K14 are smaller, and make their boost quicker. Since you'll be running less than 9psi, these turbo's will flow quite nicely.
T3's and K24's make their boost around 3000 rpm.
It all depends on how you drive.
In regards to that Ebay link, I suggest looking for a good used one off an ecodiesel instead and save that money for your intercooler and piping.
-
A smaller turbo would make more sense but i already have a t3 if i rebuild it. i think if i had boost sooner i would use it too much and want more and break something.
but if i find a turbo cheap i would get a small one. otherwise i will get the t3 rebuilt.
-
having a hard time finding a turbo that will fit the exhaust mani i have and stock downpipe. A k14 should fit the manifold and stock downpipe?
-
I can;t find a turbo that fits the downpipe bolts and fits the manifold seems like some t3 turbos have the right manifold shape but have weird 5-6 holes to bolt to. seems the same with k14s
