non working vnt is like having a non vnt turbo.

Like a non-vnt turbo without a wastegate actually...

how many other non-VNTs do you know of that will spool @ 1500 revs, and be making full boost by 2800 revs, and still pull till 5500 revs?

Not in stock engine, but my friends Schwitzer S2B hybrid boosts 0,8bar/2000rpm in AAZ. 260+hp. There are differences between turbos...

yea, mines a stock engine, and a stock turbo, with a stock pump.

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.

Frederickk, if i were you, and was debating a VNT, then i would jump on the train and go for it. you wont regret it.

i remember, back when i built my engine, there were only a HANDFUL (maybe a half dozen) older VW diesels using the VNT turbo, and now its a fairly common swap.

the info is out there now, there has been enough research and development (destroyed engines) now to know the limits of things, and such.
