Title: K-24 & T3?
Post by: Torchd on April 19, 2008, 12:14:04 pm: Whats the difference between a Garett T3 and a KKK k24?

Which one is better?

Both of them originally came with the 1.6TD in MKIIs and both the turbos put of the same horsepower and both have same size... so which is better, any pros and cons of the two?

Post by: rallydiesel on April 19, 2008, 05:27:19 pm: A con of the k24 is that the wastegate may seize up.

Post by: RabbitJockey on April 19, 2008, 06:04:33 pm: t3 is bigger especially on the exhaust side, and like its been said, the k24 likes to seize up

Why install a T3, of course. :roll: Seriously, I've never heard of a wastegate seizing on a diesel, but tha discussion points are all true. The T3 makes a little better power on the top end.

Both turbos work fine. Both are slower to develop boost than their smaller cousins like the K14 but both have a bit more top-end omph in exchange.

VW treated them pretty much interchangeably and in my opinion so can you... find a good one, install it, and move on to other concerns !!

Yeha Vince is right, MkII drivers always have other bigger concerns to worry about!

I hope your not using mine as a way of gauging that. It has a leak before the turbo in the exhaust somewhere.

Your boost would be controlled by the check valve instead of the wastegate. Boost would be a little higher so it's not that bad of a thing. Mine was seized but I didn't find this out until I rebuilt the turbo. The shaft was seized tight. So tight I ended up snapping the valve stem.
