Depends what your aims are I guess, just don't see the point on stock turbo/injectors for the investment

Well seeing as how there aren't really any aftermarket options for the 1.6 and 1.9 IDI injectors, you don't really have a choice. lol
And you still want drive-ability when you are not at WOT don't you?

Granted, but this is the TDI section

As far as I see it, there is no feasibly cheap way to safely do a "wet" Nitrous injection on a diesel without a completely custom intake.. and very expensive Nitrous setup..
Wet with meth...You'll drop your intake temps some more, and no fancy plumbing needed.

Still not a wet nitrous setup though, methanol isn't going to supply the additional fuelling for a diesel??
Water/Methanol injection is a good idea on a heavily boosted setup, due to dropping intake temps only.
8v-of-fury is right, there is not a simple cheap way of doing a wet nitrous setup on a diesel.

There's not really any point in doing wet nitrous on a diesel in my opinion. The whole reason gassers do it is because the blow up if they get too lean. A giant nitrous shot without the fuel to use it will destroy a gasser. Diesels on the other hand don't mind running lean, what they don't like is running rich (EGTs). NOS adds air
If you really wanted to add fuel when you add nitrous you could use propane or natural gas. The IDI engines don't like it (they'll blow their precups) but it is a pretty common thing to do on DI motors. Propane / Methane (NG) won't ignite on their own in a diesel, at least in the mix ratios you'd be using. When the diesel is injected and lights off it burns the propane/methane, so that is how timing is accomplished.

Care to explain to me how m/ethanol is not a fuel?

Lmao. The poster used to have a 1.9 AAZ... and for some reason I thought it were still what he was referring to haha.

Right on, I figured maybe the differing ignition points might play in to affect as to injecting a different fuel earlier.
cool beans.

cant run a wet shot on a diesel..
you CAN NOT inject wet fuel into your intake.
a diesel REQUIRES a dry shot of nos, and be overfueled, otherwise it wont even make use of the nos..
only thing i could think of to run as a fuel, thru a nos system, is to plumb a tank of propane/lng into the fuel side of the nos..
but i think that even that would be a bit tricky.. its just NOT a good idea to run a wet shot on a diesel, because it will basically be a controlled run away if you introduce fuel to the intake air..

What if you made it inject after the main burn had already started?

and how do you suggest that?
Again as stated many times, you can NOT do a wet shot on a diesel... well you can just don't expect the motor to last long.
if your really pushing it you can do propane w/ N2O

propane w/N20? So essentially a wet shot?? As you would be injecting propane with the NOS and ingesting through the intake??

Methanol is a fuel, I know this (I burn 5 gallons in 6 seconds to go 200mph, just so you know) but the quantities you inject in a water methanol setup will have no effect, it is purely there to cool the intake charge due to its latent heat of evaporation.
Also, show me a diesel running on methanol??
It will not richen up a diesel fuel mixture, at all.

Every rig with a water meth injection system, unless running pure water. Like you said, it is a fuel, and the power it produces has to go somewhere.
Advantage being it only ups your fuel when it's switched on.

Won't make any noticeable difference to enrichment on a diesel. But the reduced intake temps would be good
