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
-
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.

can you rephrase these please

Maybe 1st time with a turbos and diesels.
-
yes
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.
-
It would be nice to have some 1Y rods and pistons here.........
-
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
-
Just measured a 1Y piston, compression / deck height is 39.7mm. IE. centre of gudgeon pin to piston crown.

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?
-
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.
-
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 ?
-
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...

Exactly what I wanted to hear...I am buying a 2256vk as soon as I get the cash from the engine sale :D Giles will get you all the fuel you want...trust me.

hey macka
manny 1y engines around here
they came out in seat ibiza, caddy , cordoba , wv golfs , ventos , passat and others ..
so manny engines around here
-
hey carrizog60
the turbo dont strungle with 1y admission colectors?
witch exaust colectors did you use ?
thanks for ani outputs and help
-
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.

how come your english was soo much better over on the vortex?
-
eheh believe it or not
its becouse the demand of power LOL
i mean , its becouse writing it manny times this days
im kind of taking rust out of my ingles
im in portugal and im portuguese , not manny people to talk with and special write ingles .. if you understend me ..
thanks for ani outputs
-
hey mjf
if its with egr , no problem for my 1y admission , becouse my car its from 94 its the last ones that came out without egr and cataliser
sound goods

you are still doing pretty good.. dont get me wrong.
i would not be able to read or write portuguese at all.. hahaha.

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 ?
-
Gttdi? What engine code? EGR is in exhaust manifold, I had to grind it to fit with 1Y intake.
-
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 ?
-
i almost finish the body work this week
next its power build
i buy this car in very bad shape , rusty , with electric problems and manny others ..
i almost rebuild him complety , and make body tunning

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 ?
-
its possible to know what stuff ive in engine , with engine number ?
and engine number is that sequence of numbers ending with j near injectors?
-
the engine code is on the BLOCK.. not the head.. its right under the top water neck of the head, but still on the top edge of the block..
its a code that should start with a *
-
i cant find it any here ..
and may engine bay its clean
but its possible to know what ive in engine by engine number ?
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?
-
exaust colectors = exaust manifold
admission colectors = admission manifold
yes i know its a 1y
-
exhaust manifold, and intake manifold, how ever admissions manifold makes sense
-
exhaust manifold, and intake manifold, how ever admissions manifold makes sense
admission manifold? ive never even heard of such a thing.
-
how ever admissions manifold makes sense
please someone post photo of that manifold ???
-
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:
(http://i702.photobucket.com/albums/ww28/Dubsmoke/0000043781_01-2.jpg)
picture just fore reference, yours may not be exactly the same..
Intake Manifold:
(http://i702.photobucket.com/albums/ww28/Dubsmoke/intake-1.jpg)
again,may not be exactly like yours, but close enough to get an idea..
-
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
-
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..
-
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 ?
-
no one ?
max pressure for 1 vnt 15 ?
-
I would not go over 1,0-1,2bar. It's so tiny.
-
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..
-
Your gt1749vb is very much different than vnt15 ::) More different than k14 and k24.
-
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..
-
Oh, I thought you said 1749vb somewhere in past. Both 1749v and vnt15 is used in ALH (90hp)and AFN (110hp).
-
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" ::)
-
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..
if you run the VNT up that high tho, it will only be a matter of time before it grenades..
-
too manny
i dont plane to pass 1,5 bars
