Hi,

pherhaps i did not have write it correct, the spec is not a stock TDI spec, but it is the same spec as the stage 3 TDI (1.9 ltr. 8V) spec from Dbilias.

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

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

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

Solid and hydraulic diesel cams have same basic sircle, gasser cams has differences. Mech cams has lash ramps at the beginnning and at the end of cam profile. TD and NA has same cams, at least part number is same.

Do you guys think I could put an '84 GTI cam in and make it work if degree'd right?  That cam is solid lifter and should be a better profile.  I think so, if I use a 16v vernier cam sprocket and adjust it correctly? 

Anyways, on the turbo.  I have been using the turbo calculator on not2fast, it is a pretty comprehensive tool.  What it calculates looks REALLY good on the comp. map of a Garrett GT2052(2).  It maps out very nicely and could be used alone with boost at 6-20psi from 2200-6000rpm, or as the small turbo for a compound setup for HUGE HP. 

The calculator comes up with 185hp and a BMEP of 250psi, which is fairly conservative.  These numbers are ROUGH numbers though but the airflow calcs and maps look right.

Any experience with a GT2052 on a 1.6l TD anyone?

no gasser cam will work in a diesel.. too much overlap. if you got it to turn over, there would be piston to valve contact.

86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Hi,

i know two guys who have run an AAZ (and later an 1Z) with a gasser (gti) cam and they was happy with the cam.
For sure they have make extra place for valves, otherwise the valve would have said hello to the pistons.

well, that would definitely drop the compression, cutting valve reliefs in the pistons..

how bout some specifics on what they did? just cut valve reliefs and dropped in a gasser cam?

how did they deal with the smaller base circle?

Most likely they did exactly that.  If you look at the cam profile pic above you can see that the overlap can be centered out to make it VERY close to the solid TD cam profile at low lifts.  It shouldn't take too much to make it work.  I plan on putting a bunch of time/effort into making this motor the best it cam be, and usually the more time/effort you put into something the more work you get out of it afterwards.
