GTD nozzles - Driving impressions

[WishIHadaRabit]

I just put in my new GTD nozzles in my 1.6TD
Right away when I started the car it revved up to 2200rpm just like quickTD's car.

My idle screw is all the way out, so I backed off the fueling about 3/4 of a turn to bring the idle back down.
Car sounds great, really smooth and less clatter then before.

Going for a spin first thing I noticed is a lot more torque and under less boost (less boost because less load on the engine, I guess).

My head temp. is down 5 degrees.
And barely any smoke under full throttle.

Awesome upgrade (thanks smog)

What kind of GTD injector nozzles did you install? Same part# as QuickTD's?
Is there different GTD nozzles for 1.6 and 1.9??

[WishIHadaRabit]

Yes same part # as QuickTD.
Yes there are different nozzles for the 1.9TD but I think the GTD nozzle will fit.
Just ask Smog and he'll set you up. Here's the link for the nozzle: http://www.vwdiesel.net/phpBB/viewtopic.php?t=998

Looking for help
My car seems to miss a little at low rpm, (less with the new nozzles)
like if I'm not getting full detonation in one cylinder.

And also my idle jumps from 1100rpm to 800rpm and vice-versa (slowly goes up and stays there a while, then slowly backs down).
I had this problem before I changed my nozzles.
I did a compression test at the same time and that's good
(430psi across all 4)

I'm pretty sure it's a pump problem.
Has anybody had this problem and fixed it?
I'm wondering if it's an easy fix that I could do myself?

Thanks

I had the same problem . you must rebuilt pump and even than you can lose abaut 100-150 rpm on hot engine , especially after long run . :evil:

Stock intercooled TD
 Maybe an abrieviation of a GT which is also a TD

Another 10HP at stock rating either way
Gran-Tourismo Turbo Diesel?

Yep, sort of a GTI for diesels...  :twisted:
