non wastegate turbo
Turbo Mini Forums

Were any production cars fitted with a turbo unit that did NOT have an internal wastegate?

lots of them

Old Saab's, Audi Quattro and lots of newer turbo 5cyl Audis are a couple of types.



Why you ask ? A turbo is just a turbo.

speed didn't kill me, but taxation probably will

Thanks for that info it,s just what I wanted to hear. Are they Garrett turbo units on the Audi 5 cyl engines.
They should be around the size I am looking for.
I just would prefer an external wastegate for my paticular installation.
Once again thanks the info.
Arethere any others fitted to 2.0ltr to 3.0ltr petrol engines that you can think of?

944's have them too don't they?

The turbos fitted to Audi Quattros were KKK units.

You can fit any turbo. If you want to use an external wastegate, just jam the internal mechanism closed.

Dont limit yourself to the ancient junk turbos fitted to old cars, unless they are free

Hi,
What Stevie said. Just put a couple of extra turns on the wastegate pre-load and leave the pipe disconnected

My thinking was that, as I am planning an over the clutch installation, a non wastgate turbo would be a much more compact install and the link pipe would add some extra support to the manifold.
stevie,are there any modern non wastegate turbo's?

Hi,
I'm not sure as a turbo and an external WG is going to be compact?
More likely to be a pipework nightmare!

dave, fit a screamer pipe lol

"did you know you can toast potato waffles?"

the fact you can remotely mount the external wastegate means packaging might be easier. But in reality...integral ones are pretty compact anyway

As I said...pick whichever turbo fits your power/spool needs. Dont restrict yourself.

Its easy to make an integral turbo run off an external gate.

I don't suppose that a list exists of which Garrett unit was fitted to which production vehicle?
I am looking for a top end GT25 or bottom end GT28.

The GT28RS was fitted to some Nissan 200sx's...ya get those on ebay. Some of the earlier 200's or 180's had a smaller version of it.
Or some of the 1.8 Rover turbo's had a GT28 variant.
They call the Nissan one the "disco potato" for some reason.

Looking at pictures, although its very hard to tell.
Id be inclined to think the GT28RS Nissan turbo uses the a compressor a very similar size to what I used, although mine was a Cossie T3 compressor.
I was stuck with the 0.36 T3 turbine housing though, as the GT25's etc werent out back then

Im sure the GT28 version would have much improved spool over what I used.

The small turbo Escort Cossie's also used a GT28 or similar
