k14 vs T3?

[hanisbb21]

I'm writing a short question because I just spent 30 minutes posting pictures and a long write up just to have vwdiesel log me off. Anyways, like the title says. k14 vs T3 turbo. Any input? I have both and am debating on which one to put in my caddy and which 1 to put in my mk1 rabbit.

I'll write a short response in response to your short question.

fast(ish) off the line = k14
laggy as anything = t3

max boost 15 psi = k14
max boost 25? psi = t3

Rebuild the T3 with a 360 bearing and it will spool as fast as a K14...if you have a decent downpipe.

I had a T3 that spooled faster than the vnt 15 on tdi's. If you are looking to spend over 800.00 I would go with a holset

@burn your money. I appreciate the sarcasm.  And I agree, k14 compressor maps dont suggest that they support higher boost levels effeciently... Although I would like to study this more if anyone has factory specs on these compressors.

@theman. Where would you find a ball bearing rebuild kit? I'll start some searching now but if you know of a reputable place I'd love the input. I just installed an Auber instruments egt probe into the 1.6 TD I'm putting together right now. The first step to IDI tuning  ... After just blowing up my other 1.6 TD due to ignorance and messing with injection pump timing without and EGT, I won't leave home without one.

AND, BTW, I have a 2.5" exhaust from the downpipe.

I never said ball bearing. I said 360 bearing. Most any reputable shop should have the kit for around 100.00. xsboostturbochargers.com sell them for sure.

hanisbb21, I'm looking for a good used K14.  If you decide to go with the T3 and want to sell the K14, please let me know.  Thanks.

[hanisbb21]

I will definitely keep you in mind. Still debating between keeping the rabbit diesel (keeping the truck diesel of course) or doing an AEB 1.8T swap... I found a donor car for $500 bucks locally. Once I make that decision I'll PM you. FYI, it doesnt have the oil drain tube and finding the fittings is a pain in the arse.

[libbydiesel]

I'd be installing on a vanagon, so no need for the tube.

Like that only not that one at all. That is the 270 bearing. See the giant hole in the bottom, it is missing 90 degrees of the circle...The 360 is just that 360 degrees of bearing.

Like this one only for our turbo

[hanisbb21]

So your saying that exact part fits the Garrett T3?

[libbydiesel]

That head looks harsh, but you could probably replace the two valves, replace the one guide, smooth out the sharp edges on the combustion face and run it.  Piston is obviously trash.  Is the rod bent or block scored?

[libbydiesel]

Also, EGTs didn't cause that valve head to break off. 

[hanisbb21]

The rod is bent to ****. Can BARELY spin the engine. There were so many metal chunks in the pan (including the oil squirter) I don't think its salvageable. Plus, I already have the new/used engine back together. Although I'm having a hard time getting a broken bolt out of the water pump bolt holes.
