I need help in kowing what to look for in buying a turbo for an 85 Jetta turbo diesel engine. I bought a used 1.6 turbo engine (mechanical head) without the turbo and exhasust manifold. I need to find a replacment that will bolt up to the stock flanges (I also have the exhaust down pipe). What was the stock turbo, what are its specifications, and what do I need to look for in finding either a stock turbo or a replacement. I am going to install this in my 80 vw pickup. I have a diesel 5 speed already and want good milleage and better performance. I would appreciate some counsel and some of your experiences.
I have heard guys thow around turbo numbers but don'e know what they mean.
Is it true that the smaller the turbo, the faster it spools and perhaps give better low/mid range? What brand and model of turbos do I need to look for?
In any case I plan to bolt whatever turbo I get to the stock manifolds and down pipe unless someone else has done a similar conversion and found other parts to be better.
I would appreciate any counsel you all have.
Also, I want to buy a good used turbo, wast gate, exhaust manifold, and both oil lines. If you have one, I would be intersted.
Thanks :wink:

If the down pipe you have has a rectagular(almost square)manifold,its a t3 or k24.Buy a exhaust manifold from a 1.6. for feed line theres nice kits on ebay for the t3 ,but youll need to tap the feed fitting on the turbo or find a transfer fitting,the vw t3 uses strange thread.Intake manifold from the t3 will be fine.I made my own return line by tapping into the oil pan(http://i249.photobucket.com/albums/gg206/2253benjamin/volkswagendiesel010-1.jpg)

Hey Thanks for some insight. I'm still not sure if it is a t3 or k24. I have the square ports. Will both fit? I have the actual and complete 1.6 turbo diesel engine without the exhaust manifold and turbo. I have both input and out put line fittings already in the block and oil filter (minus the actual lines; since the seller took these also. I would like to find out what turbo actually came on the engine and the specifications so I could match to a similar turbo if possible, or hunt down an original.
Thanks for the tip. It narrows downt the search. I am wondering if it is the k24. These seem to be plentiful. Do you have any stats on the k24?
Thanks,
Greg :)

If it from a 1.6 and its a kkk its probably a k24

I looked at a couple of pictures that I took of the original turbo with my phone camera, and you are right, it is a KKK. If it is a K24 do they come with a standard retangle shaped port for bolting to the exhaust manifold and a rectangle flange which connets to the down pipe? I have the cast down pipe and it has a retangled fitting. Does the K24 come with a variety of inlet and outlet diameters for the intake?
Hey we're getting there. This narrows the field even more. If it is not a K24, what else could it be?
Thanks again. This is really helping me.
By the way, your engine looks very sanitary. Have you got it together yet?
Greg :)
