1.6TD build.

[BillyWillicker]

Hi there!!

I am finally starting a build thread!  I am building a 1.6l TD from a 1985 solid lifter 12mm ME engine.  I will be posting pictures soon. 

The head is done so far.  New guides, valves, lifters/shims, ported, seats cut, de-burred, straightened - was warped center high as most do with an overheat.  I am curious about an alternate camshaft for it, is it worth it and also need advice on which one.

The intake manifold is from and Audi 10v cut/welded into a 4 cylinder setup.  It has larger intake ports and nice runners/plenum.  I plan to use a low mount turbo on it, most likely a 1749v.

For the lower end it will be 1mm over on bore, all new bearings and core plugs.  I am also going to install 1.8t piston jets as they are easier to machine for. 

I am pretty well on my way with it and would appreciate some pointers on the camshaft and turbo direction as I still have those choices open.  I am open to ANY camshaft idea, including gasser cams.  On the turbo side, I would prefer to have a tube header/manifold and can stand a little lag.  All ideas suggestions are appreciated!

Thank you.

should check to make sure the break pressure in them is the same, or atleast close th the specs of the 1.6TD jets..

[BillyWillicker]

They're close....

Thoughts on cam/turbo...   please..    Bueller, Bueller lol

1.6TD cam is the hottest stock cam..

cant get a solid lifter giles/upgraded cam..

[BillyWillicker]

Poop.  So a turbo cam IS better than an NA cam, I thought they were the same.  Thank you.

Yes best solid lifter diesel cam not by much but it is. I think Tyler posted it in the faq

My head guy tells me that you shouldn't mix hydro and mech cams. I forget which way it is, but one has a steeper opening and closing ramp. It makes valve train vibration and he says it will kill the lifters and valves after 50,000 miles.

[RabbitJockey]

I am not certain so no one take this as a recommendation but I think hydro cam in a solid lifter engine but not the other way around. Which would be good for us solid lifter folks cause it means we could use the performance cams but I can't say any of this with confidence

[BillyWillicker]

I have run hydro solid either way.  Hydro cam is hotter in a solid head.  Solid cam in hydro head makes noise and is really weak.  I stick with the right cam for the app now.  I am pretty sure I'm looking for a mech. turbo cam now.  Thanks guys.

Any suggestions on a turbo.  I am used to larger turbo gasoline cars so lag is ok. Would a full GT20 be ok?

uh, the mech cam has a considerably bigger base circle.. so it would hold the valves open if you installed it in a hydro head..

and if you installed a hydro cam in a mech head, it would rattle to all hell, if it even ran.. instead of 3-4mm adjusting shims, you would need 7-8mm adjusting disks..

so, i would consider hydro lifters and cams to be COMPLETELY INCOMPATIBLE with solid lifters and cams..

Really?  Worked in my Audi's, just as stated.  Not anything I'm gonna do again but they ran, not too well either.

[RabbitJockey]

I thought base circles were the same but the loading just came on differently between the two styles of cams. But I could easily be wrong and I only have solid lifter cams at my house or I would just go check.

As far as a gt20 which one?  And what do you want from your car

Hi,

you can send your stock cam to dibilas (http://www.dbilas-dynamic.de/) and they could regrind it for you, but make sure to
say as often as you can that it is a solid cam and that you need a solid lifter cam. I have send them my also for my 1.6 project
and now use the cam in my 1.9 engine, because they have grinded as hydro cam. Spec will same as TDI, which seem to work quite
well on IDI also, this is the spec:
    260°/250° camshaft, lift is 9,9 mm / 9,4 mm, timming is 18°/62° - 57°/13°, spread angle 112°, valve lift in TDC 0,50 mm.

By using this you will need to make extra place for the valves and i assume also take a close look on the valve springs, if they provide
enough lifting capacity.

Best Regards

i thought tdi cams were actually worse?

yea guys, there different.. let me go check, i have a solid diesel cam, and a hydro gas cam to check..
