Ok let me get this straight will 1.9TD nozzles (AAZ engines) fit 1.6 turbo injectors?
yes
is there any benfit if they fit?
1.9TD nozzles on 1.6TD engine
SHOULD flow more fuel (no test done about it) and restore driveability/power/mpg on 15+years old injectors
will putting the GTD nozzels on regular 1.6 turbo injectors be of any benefit?
1.6GTD nozzles on 1.6TD engine
WILL flow more fuel and restore driveability/power/mpg on 15+years old injectors
how about putting any of these on 1.6 n/a injectors?
the 1.6d injector body are the same as the 1.6td
how about putting any of these on 1.9td injectors?
It look like 1.6GTD nozzles on 1.9td engine can to do a great job
http://www.vwdiesel.net/phpBB/viewtopic.php?t=1039thanks for the help. also how come there isn't a company that makes aftermarket performance injectors for these engines?
because there is no need as you can tweak the pump to give more fuel. The point in changing the nozzles is more to restore the spray patern of the injectors; it will cure some of the smoke, bad mpg, bad idle,low power output. But the GTD nozzles will give more power than regular 1.6TD nozzles.
In fact there's no aftermarket performance injectors for the TDI; we sell injectors designed for other TDI model that produce more HP. We put BIGGER injectors on the TDI to trick the ECU; while he think he send 1mg/stroke, the bigger injectors push 1.5mg/stroke. On a TD, you just need to turn up the max fueling screw to do this.
Just to add to your confusion, I have GM 6.5L and 6.2L nozzles that will fit on 1.6D injectors..... (Redrotors tried this and told us it's not a performance upgrade)
