hi all, this engine is for sale locally http://pittsburgh.craigslist.org/pts/1433965668.html
i wanted to know what it would take to go TD with it. i have a exhaust manifold, turbo, intercooler, and oil cooler. what else do i need other than injectors and pump?
-
an intake, oil lines.
oil cooler isnt even that important.
-
i have a intake off of a gas motor, too. still have the lines for the turbo
-
then what are you waiting for? get that stuff put on there and running with the n/a pump and injectors. i had a n/a pump and injectors on my rabbit for a long time before i actually swapped in my rebuilt TD pump.

well, i dont have the engine yet, and my Jetta is still gas, so......
the turbo and manifold i have is a K26 from a Audi 5000, is that too big?
-
would this be a good choice for a turbo? http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT20/GT2056_751578_2.htm
-
last question for now, do i really need a Diesel sending unit?
-
for the fuel tank? i would highly doubt it. you will need to take the restrictor out of the fill neck tho.
and yea, the 2056 is a good unit. theres a few people on here running them i think.
-
if i use the gas sending unit, do i need another fuel pump in conjunction with it, or will the in-tank pump do the job?
-
These diesel's don't even have an in tank fuel pump, the lift pump is built into the injector pump.
-
You could run the k26 but it will spool very late. If you're got a gasser trans then you will pretty much redline by the time the k26 starts spooling. I don't know much about the 2056 but it's got a t25 flange so you will need to fab a custom one or get a t3 manifold and an ebay t3/t25 adapter. I'm not sure, but I can't see the Audi manifold fitting the VW head.
-
here is a Audi manifold with a runner cut off, bolts right up http://media.photobucket.com/image/audi%205000%20exhaust%20manifold/pholness927/DSCF2477.jpg
as for a trans it is a diesel trans.

gas sending unit has a pump though. i am doing a gas to diesel conversion.
-
You don't need a intank pump, maybe just disable it.

so i can disable the intank pump, and the engine will still run?

With the diesel, yes, provided fuel can still flow through the pump.
-
ok, it also looks like then engine i am going to get has no alternator, can I use my gas alternator?

If it fit's than yes (unless someone who knows more says no ;)). If you are going to run the stock diesel tach then it needs a W terminal.
-
what year is your car? if its 84 or older, it has no in tank pumps. if it has an in tank pump. its low pressure. use it for your lift pump, it will put out about 4 or 5 psi if i remember right. just be sure to take the high pressure external pump out of the fuel line.
-
its a 1986. i wasn't sure if i needed the in tank pump, if i dont i will take it out.
for now i wont be running a tach.
-
leave it there, it will be perfect for priming the system. and it will act as a lift pump. now you wont have to sit there and crank your engine for 5 minutes every time you lose your prime or run out of diesel.
-
ok
-
well, unless of course you feel the need to disconnect it. it might become a restriction if you un plug it. thats all im thinking. you want fuel to get to the IP as freely as possible. not my project, but i would leave it there hooked up.
