Title: main diferences between 1y and azz ?
Post by: ibizz on March 05, 2011, 03:12:54 pm
hi to all

1 time in this great forum

ive already make this kind of questions in another foruns , with mutch help from some users that i see some are here too

but somethings are missing .. so il make that kind of questions here too.

ive 1y engine (atmosferic) but in my block as crafted 1.9 td ( some people says that is virtual the same engine as aaz
but without the turbo and lda in pump ..  so im thinking go turboed with vnt 15
i heard even the ones that ive crafted d and d/td ive oil injectors for cooling rods and pistons

the main questions is
compression ratio - manny people says that 1y and aaz ive diferent crs, but from what i see they ive the same
internals - think that as same pistons and rods ? or with same material ?
i already see somethings listed for this 2 engines ..
valves the same ?
aaz ive metal gasket ?
this kind of questions ..
since theres here experienced people with this 2 engines , its easy to think aswers

the main objective with this kind of preparation its to double his output hp rated at 68hp from factory
il use vnt 15 , ic , ic pyping , exaust colectors frm gttdi 110 hp
il try to keep my admission
planing put one oil cooler too , gtd or aaz pump , may be some p&p , custom dowpype and large exaust line , may be 60mm

think that i can get that figures with that set up ?

thanks in advance

i know the pistons and rods are different, one of them has longer rods and a higher wrist pin, so it will rev better but i'm not sure which one

here is a discussion i have found about 1y has longer rides and there fore would rev better.  someone in this thread says that a longer rod will make more torque because it increases the stroke,  this is not true at all, the throw of the crank determines the length of the stroke not the connecting rod.  the longer rod will not ever be putting on as harsh of an angle as a short rod would be so it is less likely bend and therefore better imo

1Y and AAZ have the same compression ratio: 22.5:1

The AAZ has 144mm long rods with 26mm gudgeon pin.
The 1Y has 150mm long rods with a 24mm gudgeon pin.

thanks for clear me out

did some one know as it as metal gasket ?

how about turbo pressions ?

1 time diesels and turbos
Title: Re: main diferences between 1y and azz ?
Post by: RabbitJockey on March 05, 2011, 09:51:17 pm
i don't know whether or not it has a metal head gasket, unless it needs a head gasket, i wouldn't change it anyway, a metal would would work on it tho.


turbo pressions?

1 time diesels and turbos?

can you rephrase these please

1 time messing with diesels and with turbos ..

im refering to turbo pression advices for this engine .. i dont ive ideia what he can take

I have stripped a few 1Y and AAZ engines, and they all had a metal laminate head gasket.
The 1Y blocks were marked 1.9TD and had oil squirters too.

Post by: RabbitJockey on March 06, 2011, 06:50:39 am
1y pistons have the same wrist pin height as a 1.6td, so you could technically use them to make a 1.7td, but only if a 1.6 block can handle that much of a cut
Title: Re: main diferences between 1y and azz ?
Post by: danster on March 06, 2011, 07:03:51 am
Just measured a 1Y piston, compression / deck height is 39.7mm. IE. centre of gudgeon pin to piston crown.

And 1,6 piston is 41,7mm.

Either compression ratios, or how much boost pressure from the turbo is what he is asking.

sorry for my rusty ingles ..

i im asking turbo pressions
im imagine there must be conservative

do you guys think that 1y stuf handle as mutch abuse as aaz ones?
Title: Re: main diferences between 1y and azz ?
Post by: MJF on March 06, 2011, 02:33:21 pm
Use AAZ or Tdi con rod bearings and you'll be fine. I'm now running about 180hp/350nm, no worries. It's AEF, same internals as 1Y.
Title: Re: main diferences between 1y and azz ?
Post by: ibizz on March 07, 2011, 02:34:53 am
its possible to use con rods from aaz or tdi in 1y rods?

you ive it in your setup ?

witch pump is beter aaz one ore gtd one ?
Title: Re: main diferences between 1y and azz ?
Post by: carrizog60 on March 07, 2011, 05:24:52 am
i have done that,in a passat 35i.

gt2052v turbo boosting at 1 bar for now,1Y intake manifold,60mm stainless exhaust,gtd pump.

still need more fuel as the big turbo and better manifold clears all the fuel smoke only at one bar...

so manny engines around here

the turbo dont strungle with 1y admission colectors?

witch exaust colectors did you use ?


thanks for ani outputs and help

Post by: MJF on March 07, 2011, 06:56:16 am
You want to use 1Y intake manifold and AFN (110hp TDI) exhaust manifold? That's exactly what I am using now. EGR mount from exhaust manifold will hit intake, you need to grind it some.

hello

i used 1Y intake, but had it resurfaced with a bit of alge to help clear the exhaust.
did the same on the exhaust manifold.

the exhaust manifold is a 1.6gtd,but was cut and the exhaust side of turbo welded,because of lack of space.
on normal(bolt on) assembly the turbo will hit the firewall...


portuguese is not an easy language...
but i am smart and can speak,read and understand pretty good lolllll


um abraço da zona de aveiro ;)

my 1y dont ive egr so it must have more space

il use gttdi turbo and colectors , since is a litle turbo and dont ive egr may be its bolt in right without mood ?



Title: Re: main diferences between 1y and azz ?
Post by: MJF on March 07, 2011, 10:44:52 pm
Gttdi? What engine code? EGR is in exhaust manifold, I had to grind it to fit with 1Y intake.
Title: Re: main diferences between 1y and azz ?
Post by: ibizz on March 08, 2011, 02:31:02 am
mjf

seat ibiza gttdi 110 hp afn engine i think

since my model car dont ive egr and cataliser , the admission manifold must not ive that egr port on it , but i didnt see so far

becouse engine are running


did you already use the con rods from another engines in 1y rods ?

AFN exhaust manifold has EGR port. You will have to make a plate to block it. And grind some material above the port. Otherwise it will hit 1Y intake manifold.

I have stock AEF (1Y) con rods and bearings. 1Y bearings are same as 1,6TD, these will be good at power levels you mentioned. But AAZ bearings are 1mm wider. AFN upper bearing is better material, these are the best. AAZ and AFN bearings will fit directly to 1Y con rod.

thanks friend

yes exaust colectors ive egr port , that must be close
but my admission manifolds dont ive that egr stuff that you guys cut , becouse car dont ive egr from factory

lets see if its plug and play ..

ive to start looking for a pump

witch best aaz or gtd ?

or just with code engine?

what do you want to know? didnt we determine that you have a 1Y?

and whats an admissions collector? an exhaust manifold?
Title: Re: main diferences between 1y and azz ?
Post by: ibizz on March 10, 2011, 04:26:20 pm
exaust colectors = exaust manifold

admission colectors = admission manifold

yes i know its a 1y

Post by: R.O.R-2.0 on March 11, 2011, 09:18:03 am
the one where the engine sucks in air?
or the one where exhaust comes out?

the turbo is driven by the exhaust manifold, and the boost is fed to the intake manifold..

no admissions manifold that i know of.. or atleast i dunno what manifold you are referring to..

im trying to find pictures of the manifolds tho..

Exhaust Manifold:

picture just fore reference, yours may not be exactly the same..

Intake Manifold:

again,may not be exactly like yours, but close enough to get an idea..

Post by: ibizz on March 11, 2011, 02:07:22 pm
here call it admission colectors
and exaust colectors

but it exaust manifold
and intake manifold

that intake manifold is not like mine

mine its large like that one carrizog60 passat

same as 1y ive here

Post by: R.O.R-2.0 on March 11, 2011, 02:18:18 pm
oh crap, i forgot you have a n/a 1Y engine..

those are AAZ/TDI manifolds.. they are for turbo engines.

yes, your intake manifold would be much longer, and shaped just like a gasser intake manifold..
Title: Re: main diferences between 1y and azz ?
Post by: ibizz on March 11, 2011, 05:53:05 pm
they are longer and seems beter then aaz and tdi ones

so i would like to keep it and since it does ive egr on it ,must give space for plug and play with exaust manifold from tdi and vnt 15

does ani one know what is the max boost in 1 vnt 15 ?
Title: Re: main diferences between 1y and azz ?

i run 25 psi all the time..

its seen spikes of 40, and also exploded an engine block at ~40 psi...

they may be a tiny turbo, but they flow awesome (for what they are) and have hardly any lag..

mine isnt a 2 piece unit like whats off an AFN.. its a modular unit just like a VNT15.. everyone that ive talked to says my turbo is a VNT15, but it says GT1749V right on the cold side..
Title: Re: main diferences between 1y and azz ?
Post by: MJF on March 13, 2011, 01:51:43 pm
Oh, I thought you said 1749vb somewhere in past. Both 1749v and vnt15 is used in ALH (90hp)and AFN (110hp).

Post by: regcheeseman on March 13, 2011, 03:23:03 pm
I've tuned a T4 recently with a VNT15 fitted. They're tiny.

When I saw it I said - "has barbie lost her hairdryer"

I struggled to get 15 psi, but the owner wouldn't let me turn the fuel up anymore because it was "getting a bit smoky"  ::)
Title: Re: main diferences between 1y and azz ?
Post by: R.O.R-2.0 on March 13, 2011, 05:54:35 pm
mine only makes smoke off the bottom end, and thats probably because of my n/a inj pump..

i make 20 psi if i really wanna hold some RPMs. i usually dont push it anymore than 15psi most of the time..

i dont have my fueling turned up that much tho. i have alot of screw left. i dont have a collar on my fuel screw, but its not much past where the collar would be..

tiny turbo with great performance

mine says vnt 15 in cold area

and they re really tiny at eye , but they seem huge in performance and boost gauge


40 psi its = how manny bars ?

just shy of 3 bar..
