1.6 cy TD bottom end 1.9 aaz head project

[NintendoKD]

I am rebuilding my own injectors, which nozzles should I use, and what breaking pressure should I go for?  Keep in mind that I am building a fire breathing dragon here.  As I understand it, the higher the braking pressure the more atomized the diesel becomes, allowing for more adequate burning of the fuel/air mixture, thats good right?  So the object is to increase breaking pressure right?  I have heard good things about using other nozzles and I'm curious to try some for myself, where do I get the thicker shims and nozzles?

thanks,

Kevin

Forgot to mention that these are the two stage aaz injectors and they have two shims/spacers, I checked vinces' webpage, but he doesn't list where to get the "STUFF "

I am having a hell of a time finding the info I need.  I have used the search function to no avail   please help.  I know, I'm so needy, but this is my first diesel and my very first build, I'm still learning, and I still have such a long way to go.

thanks guys,

Kevin

I dont know much about the two stage AAZ injectors, but I have heard that they are a royal pain in the butt to calibrate opening pressures, lots of people with AAZ's use the 1.6 injectors as they are easier to calibrate, and are just as capable of making big power.

as for the opening pressure, there is some debate, but if you increase opening pressure there will be more parasitic power loss from the injection pump, and timing will be retarded(as it takes more time to generate the extra pressure)

I would say, using 1.6 injectors and leaving them at stock opening pressure would be just fine(130 or 155 BAR depending on the pump used)

I am using a late td injection pump and swapping a rover pin, eventually send it to giles when I have the cash.  I have had the aaz injectors apart and the design isn't complicated "or so it would seem" is it possible to manually advance the timing or is that impossible?  advanced manual timing with retarded injectors?  In other words, is there a way to compensate, and does this affect max revs? "I want to get as high as possible, which I'm told is rather limited mostly by the pump"  There appears to be a sort of resonance/pulse between the two springs/injections how does that affect performance?  Has anyone played with them?  Who, if anyone, is running a performance aaz injection setup?  and if worse comes to worse, where can I get a set of the 1.6 injectors?  I have the ones from my 1.5 will those work or are they different?  anyone want to trade for some really clean aaz injectors?  Lets just say for arguments sake that I get the 1.6 injectors, I have heard that there are different kinds, does this refer to the nozzle, either way which nozzle should I use and I want dyno proven results to back it up if someone has them "a lot of speculation has driven me to do this"  Once again, sorry for all of the questions, but that's why I started this thread for my build.  I also do not want to sound ungrateful for all of the wonderful advice and help I have received thus far, and if it sounds like I'm using you, just so you know, that isn't the case.

Cheers,

Kevin

P.S.  My new...er aaz head is finally on it's way *fingers crossed*

Makes sense, the pressure has to have time to build up, and it takes more time to do this, especially at high rev's. Is there a way to compensate pump wise, or otherwise for that matter?

This is what I'm going for turbo wise, but I don't have that kind of money to drop on it.  The search continues for the parts necessary to do this.  I have heard that the dodge sprinter has these vnt-22's but where can I get a vnt-17?

WOW! I have come a long way from page one, and still such a long way to go, but I could not have done it without everyones help.  Thanks.

Found my rover pin/modified boost pin, thanks rabbitonroids.  *breaks out into song, visions of QUEEN*  "and another one bites the dust"  one thing down...... nine million more to go

[NintendoKD]

is this the right sprocket?

Ok, so I think I got the necessary cam sprocket from ilikevwdiesel, thanks.  I got the "not the rover pin" but a peugeot boost pin from reanp, thanks to him and thanks to rabbitonroids for the suggestion.  So now I need:
1:seals, rings and bearings for the 1.6 td bottom end
2:mod the oil res. to be a dry sump pan
3:uprated oil pump
4:arp studs for everything
5:oil lines, fittings for the oil reservoir turbo cooler etc. "gonna be a spaghetti bowl of oil lines, and I'm gonna be soooo paranoid of leaks it won't be funny"
6:oil cooler, reservoir
7:vnt 17/22 hybrid
8:1.6 single stage injectors? "still torn between the aaz injectors with a different nozzle or these"
9:nozzles
10:intercooler and piping
11:exhaust mani, and D/P "homemade turbo headers anyone?"
12:mech lifters for the aaz head courtesy of another members hard work and dedication
13:oil return pump, fuel lift pump and toggles
14:guages, and thermo couple wiring and more toggle switches "noticing a trend here?"
15:toggle switches  :PJK fast glow plugs and relay
16:upgrade the charging system
17:meth injection system baby, ooooooohhhhhhh yeeeaaah!!!
18:insert small dumb stuff here that you don't think of but def. need
19:insert things that will go bad that I forgot to replace thanks Arb for this one, and I just know it will happen so I might as well just start dissasembling the head and reassembling it again.
20:insert stuff here that I forgot to add than everyone here will be sure to chime in on.

none of this is in chrono order so it's not nec. the way it's going down.

Went to my friends garage and used his media blaster today "he needs new media, so I'll front it for his kindness" I'll post up pics tomorrow.
goin to hit the rack,

found the vnt22 and I have a friend who rebuilds turbos, so now i'm in buisnesss in the turbo respect.  I'm haveing trouble finding the info on the hydro head plug for the return hole from the putting a hydro head on an mech block, anyone help?

1.) turn head upside down
2.) locate front small oil drain
3.) tap threads into it
4.) install half inch pipe plug, or whatever size it takes, cant remember exactly right now.

no ***, its that easy. then you gotta cut a piece of rubber gasket to go in between the water jacket port and the hole in the AAZ gasket for the front oil drain.
