Hi guys,

First, thanks for the great site! I think it really speaks well of a company when they have a forum where employees chip in regularly.

Second, I've decided that I'm going to get a DO system but I have a few questions about my application as it is a little different than most on here.

I have a Toyota truck that I swapped a 92 JDM turbo diesel engine into and have converted into a 2 tank straight vegetable oil system. It's a 2.4 litre (toyota engine code 2l-tII) that is very common in the rest of world but pretty uncommon here in the states. I see that dvldoc is in the Philippines and probably sees rigs with this engine many times a day. Anyway, I want to add water injection to limit the build-up of carbon due to burning veggie oil on the piston heads and valves and am less concerned about any power gains or EGT changes (although it does seem to run pretty hot, non-intercooled).

- What nozzle size should I be using? I'm thinking 3 gph?
- I know I should mount post-turbo and the best location is in the pipe that crosses over the rocker cover. However, it's very thin, 1/8th inch or less, and aluminum. Will I be able to mount the nozzle in this pipe without air leakage issues under boost? The other option is in the intake elbow after the crossover pipe (also aluminum but thicker) but I would like to have all of the water in the gas phase before it sees the chamber to avoid any pitting. The spray would travel about 7 inches, is this enough distance to vaporize it?
- As I am less concerned with power gains and interested in the "steam cleaning" I would like to limit the amount of methanol in the systems, just enough I keep from freezing in the winter (gets down to about -20F), what mix would you recommend?
- What is the difference between the diesel universal kit and the regular universal kit? Different nozzles? I would like the smaller pressure switch because my turbo only boosts to 10 psi max but it's only available on non-diesel kit.

Whew... I think I'm done, thanks for the help and for putting out a great product.

There was a long discussion about this very topic on a biodiesel website, and I too am looking at getting water injecton for the 2L's big brother the 3KZTE. If you have a pic of the engine it might help the brains in here to locate a good spot for it. I think that the water would also help you boost it up a bit too. Where do you live, and how did you get the engine to the states?

The differnce between the 2 kits is the diesel kit come with hardware to run 2 nozzles. You would be better off with the regular kit.

1/8" thick would be desirable. Just drill the hole and run a tap thru it. Then use the suppled nozzle and you should have no problems

The reply message field is all black. How do you guyus write messages with this system?

Thanks for the help guys,

So I'll get the regular universal kit, does that come with the 3gph nozzle? I think that the crossover pipe might be thinner than 1/8th of an inch, more like sheet metal thickness, would I still be ok? Perhaps I could thread a thin nut on either side with a high temp o-ring to seal it up and lock it down if it turns out to be too thin to tap.

Dust - I'm in Seattle now but I just moved from Montana. I bought the engine from a guy who imported it via Jarco when you could still get complete half-clips into the US. I understand that that is no longer legal although everything is still available, just not bolted into the frame. The 1KZTE is a hell of an engine and probably a little more solid than the 2l-te. That's what I would have gone with in a second if I had the money, my engine was about $3,000 less then a KZT clip. I think they are drop ins for the 96 and newer Taco and Runners with the 6 cylinder engines and there is a guy in the states who will do the wiring harness for about $500 so the hardest part of the swap is pretty much a non-issue now. Wow, now I'm rambling, thanks for the info...

I would love to make some intellighent replies, but I am stillstuck with the black background and I can't see my own writing. What gives?

Good forum for this engine - ToyotaSurf Australia Site

[Dust]

Are you on any of the hilux/surf sites. I know there was a guy in England who bought a kit while ago for his surf, but he hasn't been on lately. I am still trying to get some info on the car I am looking at buying. If you don't mind, will you send me some info (pm) on how much you have in your swap.

[Terry Syd]

I'll try changing the text to torquise, maybe you can read it (Hell, at least I can). (Hmm, tangerine seems to work well!)

I'm on both the Sydney Biodiesel forum and the Surf forum, I use the same sign-in name. I run biodiesel, right now it is summer and I am blending in 33% vegetable oil with the biodiesel. This is a good injector system for alternative fuels.

Before firing up the engine in the new truck, fix the temperature gauge, you will find a thread on how to do that on the forum. If the temperature is running high, then fix the viscous clutch for the fan, again on the forum. These engines can crack heads if you overheat them.

After it is running (and not overheating), then fix the boost compensator, see forum. The stock cam is an off-road torque cam, the 3L (2.8 litre) cam is a general purpose truck cam, it drops right in.

The Hilux runs a slightly shorter radiator than the Surf. I am using a 4-core radiator. The fan on the Surf is larger in diameter and has a larger opening on the fan shroud. I use a Surf shroud, a rebuild Surf viscous clutch and a larger Landcruiser fan with 8 blades off a 4.2 liter engine - no problems with overheating.

My brother has ordered the WI system and is playing around with it on his Merc 300D. After he has used it for a couple of months he will send it on to me and I'll install it. I'm running 9 psi boost.

I go off-road a fair bit, so I use a limited slip diff. The diff is a 4.56 and I use a 15" rim in the back with a slightly larger tire, speedo stays the same as with the stock 14" rim.

Great truck, and parts are readily available anywhere in Oz (eat your heart out!)

Terry - I can see your replies just fine, must be a southern hemisphere thing .

I'm well aware of the cracking head issue or at least the previous engine owner was because he experienced it first-hand. Fortunately for me he bought a brand new Allhead (aussie company) replacement which is supposed to be much stronger as well as eliminating the design flaw dead spot at the back of head where an air bubble can form by attaching a screw in fitting that sends coolant from the back of the head to the upper rad hose. In addition I'm running the Allhead "improved" water pump so I'm less worried about the head now. I also have a Surf radiator.

I was running a Allpro coolant bypass fitting on my lines which meant that my engine was not even approaching the half way mark on my temp guage and actually ran much cooler than the gasser. I got rid of that for practical reasons when I rerouted my coolant lines to heat my veggie oil and it's running hotter but still hasn't ever surpassed the halfway mark. I haven't worried about the temp guage mod because I have an EGT installed that seems like a much more accurate real-time measurement of how hot the engine is getting than coolant. However I can push my EGT's to over 1300 F on hills. This is partly due the fact that I can't advance my timing to the correct place on the pump because I converted it from an electronic pump to a mechanical and the dimensions of the intake prevent me from doing so. I am thinking about advancing the pump from the pulley under the timing cover and then "retarding" the pump via the mark to match it up but haven't had the gumption to do so yet. There is a definite loss in power with the mechanical pump but I think it is better for veg.

Good to see another Toy dieseler on board, have fun!

Dust - check pm's

[Terry Syd]

My engine was an imported EFI engine that someone put the mechanical pump on. I did a bit of grinding on the manifold and can now set my timing anyway I want.

The mechanical pump can be set up to work really well. Check out this thread - Toyota 4WD Surf Owners :: View topic - 2LT Boost compensator

Glad to see another diesel Toy truck enthusiast that is moving to WI. Maybe by the time I get my package, you will have already sorted everything out.
