As some of you may know, i bought an 81 rabbit diesel about 2 or 3 months ago... it had its usual rabbit issues (mostly electrical), but i got most of them fixed (the important ones anyway)... well i decided it was a little too boring to drive because it was a 4 speed manual, so about a month ago i swapped it for an FK with a .71 5th gear... it was more fun, and a bit more responsive, but it still needed something... IT WAS TOO DAMN SLOW!!!
so..............
i decided to slap a turbo on that ***...
parts needed for the build:
-K14 TD turbo
-misc. piping
-air filter
-oil lines
-oil pan
-boost gauge
-down pipe - $200 for everything listed so far (i got a deal)...
-MK2 TD intake manifold - $40 shipped
-EGT gauge - ~$50
-EGT probe - ~$30
the necessities:

the motor before:

first we removed the intake manifold, exhaust manifold, and stock d.p....
(http://i80.photobucket.com/albums/j184/GasPanic502/1TD2.jpg)
then we put the new intake manifold on...
(http://i80.photobucket.com/albums/j184/GasPanic502/1TD4.jpg)
then we attatched the turbo...

test fitting the elbow...
(http://i80.photobucket.com/albums/j184/GasPanic502/1td6.jpg)
after this, we took off the old oil pan and scraped off the old gasket (ugh!)... we used a gasser oil filter flange and put the oil feed line on the top hole (sorry, no pics of that)... we then attatched the old oil pan and the oil return line... after that we put on the downpipe... now its time to get the gauges working... 8)
dash before:

its all done... 8)

looks like you are still running NA injector pump?
I ask because I'm debating putting a NA pump on my TD long enough to get a giles rebuilt TD pump.
-
o yea... question...
my EGT's are hitting a maximum of 1200F... could i increase my fuel? if so how much??

it runs just fine, its just not nearly as fast as it would be with a TD pump... i like it tho...
-
I'd be careful to increase fuel too much. Perhaps look into a washerfluid injection system? (homemade methanol/water injection system)

what about running an oil cooler just between the oil filter flange and the turbo so that the turbo gets cooled a lot?? or would that make the oil too cool to protect the turbo?? thanks for any info... :D
-
putting on an i.c. this weekend and turning up the boost... do i have to have a boost controller or is there a way to adjust the waste-gate??

I don't think that would make any significant for EGT's, if that's what you're thinking. Cooling the center section of the turbo won't cool the exhaust gasses. Probably obvious and not answering your question. But I don't think you can cool the oil too much to protect the turbo. I would say anything above 150 degrees or so would be safe for the turbo. If you were talking 30 degree oil I think that would be a problem.

yea.. i wasnt trying to lower EGT's.. just keep the turbo cooler... any idea on the wastegate question?
-
We are only about 10 days apart on our TD builds! Trust me, it's fun with a lot of fuel. Just one major problem: I'm now in the middle of a head gasket replacement. I did a top-speed run on Saturday morning and blew it. :oops:
Time for a 3-notch HG & head studs.
-
You'll want to put something on that valvecover vent hole. I capped mine with one from NAPA. I think it ran me about $7.

are you saying i should just block it off?? cuz i thought it had to breath...
-
no your right, it does need to breath... but i would recommend some sort of air breather at least to prevent oil spray everywhere
-
This is what I used to cut the oil spray down: http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=470&LineCode=BK&PartNumber=7354702&Description=Valve+Cover+Breathers
It still steams, but the oil spray is gone from the firewall. I just cut a short section of 3/4" ID heater hose to connect the two stubs.
-
so are you just running what ever stock boost is?
Have you adjusted your IP at all?
I think i may have to do this if i can find a set-up at the junk yard.... if i can turbo my gasser for $300, i be i can do this for $100 :D
-
its 8psi (which i believe is stock), i added a VERY LITTLE amount of fuel (turned the smoke screw in about 5 degrees...
-
what percent do you think the turbo added....see the thing is. if i could get an extra 10-20 hp i could get up the freeway hill next to my house without pissing anyone off.
-
it probably added 5-8 hp with the stock NA fueling and 8psi of boost... with an IC, more boost, and more fuel, it would probably add between 10 and 20 hp... just depends on the car i guess..
-
My vote is 20hp on my Rabbi. It changed it from dangerously slow to just dangerous. I am running 12 psi though and fuel is turned up. It makes nice noises to boot.
-
Im also in the middle of both a headgasket and turboin my 1.5 stock rabbit
Wanna make a bet who's going to need rings first?
Nice build and keep the text/pics coming man
This is good motivation
-
My head goes back on tonight. I'll be keeping it at 12 psi at least until my ARP studs arrive. Stock are going back in for now. (new stock that is)
-
then arent you going to waist a head gasket then by compressing it and then having to change studs later...?
Can you do them one by one?
-
found out where i can get a hold of a TD block... ill be rebuilding it and beefing it up a bit and possibly buying a TD IP... ill also be getting the ARP studs, a new head gasket, and possibly a new head (i think mine may be warped... ill have a machine shop check it out before it goes on the TD block)...
-
anyone have a complete 1.6TD head?? if so, i may be looking to buy it in the next couple of weeks...
also lookin to put an LDA on my pump... how difficult is that to do??
-
I've got a 1.6 NA with a Giles pump. I wonder if the increase in fueling and rev-range would boost EGT's too high if I did the same turbo install?
Thanks for the pics, this is great.

the boost should lower egt's if you do some sort of IC, and keep them either about the same or maybe a little lower without the IC... i never had a pyrometer before this install, so i dont have anything to compare it to...
-

This tell's about it, I think the verdict is that it is possible, this tell's how. http://vwdiesel.net/phpBB/viewtopic.php?t=5031
Hope this helps! :)

I asked my hot-rodding diesel-mechanic friend and he claims that there should be no ill-effects by doing them one-by-one. TDI guys have been doing it for awhile now.

i need to hurry up and get some sort of exhaust system on this ***.. the open downpipe is makin me high all the time haha..
