main diferences between 1y and azz ?

[ibizz]

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

[RabbitJockey]

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

[RabbitJockey]

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.

[ibizz]

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

[danster]

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.........

[RabbitJockey]

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

[danster]

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.

[ibizz]

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?
