The mk3 1.9L TD power-quest

[Greg Roles]

Before you get too weld happy, I noticed supercheap have Monza ( chinese ) oil catch cans for $59. I've had one of these before, and they are pretty crude, but a reasonable starting point. I put some pot scourers in mine!

meh - i can knock one up at work for little money and have it work perfectly.... might as well, then i can say its mine.

new 'cooler piping

well, a little update,
took apart the old intercooler piping setup in order to optimse it a bit, and get rid of 2 very tight rubber hose bends - and i came up with this....



also, i de-EGR'd the car. after taking off the cast alloy fitting that bolts onto the top of the intake manifold in order to inspect it, i was disgusted to find an enormous buildup of black goo - consisting of exhaust carbon and oil mixed together. i belive this is a trait of the early EGR setups which works very well to gum up your intake manifold.

i made up 2 blanking plates - one for the exhaust mani, and one for the inlet, and then just removed the rest.

i figure that hte exhaust blanking plate will be perfect for mounting a EGT sender, and the inlet one might be good for inlet air temp.

i also found that the intake manifold is grossly goo'd up aswell, but until i pull the turbo off, i cant get to the intake manifold bolts. therefore, it will have to wait - goodness knows how much power and efficiency is lost with all of that goo in there!

cant wait to pull the turbo and clean all that goo out now!

Looking good dude. Sounds like you're making progress. Good stuff!

[Mischa]

updatesss?

[gldgti]

Ask and thou shalt recieve.. or sommint

I have decided no more k14, its just too small

so i'm going to throw in a nice little... urm i mean BIG T3. woot!

theory will be that with even less exhaust backpressure let the engine breath better at high revs, and i think free it up in the criuse (3000rpm) so that it can jsut tick along at 3-4psi. at the moment, with the electronic wastegating, i can just cruise with no boost, and when i try to overtake someone or go up a hill i'm stuck with 12psi or more, mo matter how light the throttle is - simply 'cos the turbo is so small!

pics of the t3 will be along as soon as i can get time to pull it off the old passat engine.. would have done it today but i might have been building a frankenturbo with a certain other forum member

[GoLfMan]

sounds awesome mate, ill be PM'ing you soona bout turbo upgrades for my TDI

[Mischa]

frankenturbo i like the sound of that

are the aussie delivered/sold mk3 diesels the same engine as yours?

[Jarred]

T3?! Nah no big enough!

Gotta go a GT25/28R, boost it up, yo!

lol boost will hit at 4k and he'll have 1k of power to play with

someones on the money

i hope with the t3 that it'll really start to spool about 2500rpm.... right where my peak torque seems to be. then it'll be breathing easy right through the power band, and it should criuse beutifully. I'm sure i can get better economy with a bigger turbo.

[GoLfMan]

hmmm T3 would be good. how much HP are they rated too?

[Jarred]

depending on trim, but roughly 250Hp i believe

about right... so way above my needs...

i have seen video of a mk3 caddy (skoda) doing 10 second quarters with an AAZ (my engine) and just a big turbo (t3/4 hybrid i think it was... or equivalent).

the aussie delivered diesels (as far as i know) were all TDI's (mollins 1z engine) and not AAZ's.

T3 would be the one I reckon. Just make sure you pick the right trim, that's the fun part!

What would you go if you went smaller though?
