Ko3 on 1.6

[myvolkswagen]

I'm thinking about running a ko3 at 15 psi because I want that punch down low instead of having to constantly rev the bag off the engine to make some power. Anyway my question is will it still have good passing power on the highway because I have heard the bigger turbos are more optimal there

VGT15 or VGT17?... best of both worlds

[R.O.R-2.0]

a K03 is neither of those..

and a VNT 15/17 still runs out of breath up top.

i drive one daily..

[keaton]

what i meant was, put a VGT15/17... the 17 is too small you say, then got to a VGT22?

[R.O.R-2.0]

ive been told that VGT and VNT turbos are very different..

and for the fact that the garrett ones say "VNT1749xx" right on them.

there is indeed a difference. the turbos john deere uses are VGT.

the turbos TDIs, and duramax's use, are both garrett VNT turbos..

anyways.. im talking that in the last few hundred RPMs of power, they run out of breath.

they hold boost till red line. mine pulls hard to 15 psi, then its at about 20 psi if i rev it to where the pump rollers skip..

its not surging i dont think. (isnt that where it goes faster, and still makes the same boost?)

but i dont have my vanes hooked up either.. they were coked up when i got it.

anyways, to reply to the original quote, it will be fun to drive, but its not going to have the big pull up top like a big turbo would.. its gonna have lots of power down low, and be really peaky.. not really bad, but the power will definitely peak when it goes out of its efficiency range..

The k03 on the 1.9 AHU is incredible! I can't imagine it would be too much different on the 1.6. I actually had a similar thread a while ago to put my tdi setup on my 1.6.

What I found is that the k03 is efficient to 18psi intercooled. And can pull 18 all day. Any more and your not making anything better for any component of the engine.

It will be awesome torque wise. And honestly what rpm are you going to be cruising on the highway? Most likely you'll do better than a big turbo simply because your more than likely going to be within 23-2800 rpm's highway.. And that will be right in the mother load of the k03 a T3 will just be coming on boost at 2600 on the hwy.

Smaller turbo's ftmfw

it will be more fun, and not top out as quick on the 1.6

surging happens when the turbo is putting out too high of a PR with too low of a flow rate.  the pressurized air is able to over come the compressor and force itself backwards through it.  its really hard on the turbine shaft, and can cause turbo to blow to pieces sending shratnel into your intake.

ok, well then the surging is when the turbo starts to scream like a G-60 supercharger. lol..

i used to surge my VNT daily.. they MUST be great little turbos..

Ya it's off a 1.9. I think I'm gonna just give it a go. I think I'll like it better. And ya probably 2800-3000 so if you didn't downshift it should pull pretty hard

[R.O.R-2.0]

my turbo setup, i can be in 4th gear, going about 40, and just slowly lay into the pedal, and soon, im going 90+

[RabbitJockey]

surging is usually a barking fluttering noise, and its usually happens with too big of a turbo,  i dunno what noise ur turbo was making it was probably just some funky over spun noise haha.  i drove a tdi beetle with a burnt up vnt turbo and it sounded like a g60

Swapping to a K03 will require you to change the exhaust manifold, turbo, oil drain line, intake hose from airbox to turbo, intake hose from turbo to intake manifold and also the downpipe. There might be more that I am missing. I think that only the oil drain and intake hose from airbox to turbo will need to be custom. You are going to need to bend the oil feed line as well. All the other pieces off the MK3 should bolt on no problem.

I have both the t3 feed line and the ko3 one and the t3 line fit on with very little resistance. I have pieces ready for the drain aswell. I'm not overly worried about the other pieces either. I have lots of stuff to build custom pieces
