A blow-up parts diagram with parts numbers for the 1.6lTD Garrett TA0304B is available on-line here and specs on the compressors are available here, and turbine wheels here. Referencing the appropriate part numbers to these tables, and using the measurements I took directly from the guts of the 1.6lTD KKK turbo, we can compare these turbos more closely...garrett compressor: blades: 6 wheel diameter: 60.00mm inducer bore: 35.40mm tip height: 3.00mmkkk compressor: blades: 6 major, 6 minor (12 total) wheel diameter: 60.5mm inducer bore: 37.5mm tip height: 4mmfindings: nearly identical compressor wheel OD means pressure ratio capability of the two are about equal. However, ~6% larger inducer bore of the KKK means it can flow a bit more air. There is also a very significantly greater tip height with the KKK turbo (33% greater on the KKK).garrett turbine: blades: 11 wheel diameter: 59.00 mm exducer bore diameter: 49.00mmkkk turbine: blades: 12 wheel diameter: 59mm exducer bore diameter: 49.5mmfindings: except for one additional blade on the kkk turbine, the turbine sections have nearly identical specs.
first off, this thread is in the wrong section second off, the turbo oil filter flange, is indeed special.. the n/a unit will not work.the only turbos available on VW diesels that are water cooled, are not available in the USA..what turbo do you have that needs water cooling? not one off a US or Can spec TD, thats for sure.anyways, you might get more help if you posted up in the IDI section, being that you are working on an IDI diesel hope we can help..

I'd like to plumb the coolant to the turbo off the stock plumbing I don't see a need to run an auxiliary system. As for a bigger radiator I dont know how I'm going to plumb the front mount with the stock rad in place it's going to be tight. But a aluminum rad could be made and better electric fans could be used also. As for the oil squirters and the lda I'm not sure if I need them as of yet. They don't hurt thats for sure but how does the lda work with the gov mod? Since it's an Na block I don't have oil squirters so I'm just gonna have to watch my egts
I think what I am seeing in this thread is digresssion from the orginal question and bickering about whether something will and wont work.So cooling, lets head back to it.Something that has crossed my mind is that other than a water coolant line and aux pump for the turbo(which although not fitted to all cars would be an advantage to help the turbo live longer) Is actually other cooling for this, for example you may want to also look at running a bigger radiator if the main cooling loop is going to be under more strain with the turbo heating the system up as well.Theres also the other thing that I think which is things like piston squirters and an LDA for fuel pump advance so you have a TD to start with as your base and then you can worrk about the turbo spool after that.
the water flow is pretty simple actually, basically forget about the radiator hoses, the water pumps out side flows in to the block, so the outlet on the side of the head towards the transmission is on the out side of the flow, everything else flows in to the pump, so the 2 heater hoses would be good to use to cool the turbo and would basically be the same thing as using the 2 hoses for the factory oil coiler.
If you don't use an aux pump, then the coolant WILL boil in the turbo on shutdown. Better to not use the water cooling at all.
what would be real sweet is you can actually get a freeze out plug that has a water port built in, i think it comes from a mk4 vr6 or a tt 1.8t or something, but it fits our blocks, then you could run one hose from the back of the block to the turbo, then run a another hose to the return on the heater hose, that would be the cleanest way to do it.
