If you move the trans forward you will not need the body lift. I would try and go 2 inches but 1 I think would do. You can probebly get a whole car cheaper then just the engine. You don't need to use the VW rad but diesels need more cooling a a diesel rad has a lot of tight packed fins. Also you need the inlet and outlet to be swapped from stock toyota, I turned the VW rad upside down to do this.

I had the truck out for a good run today. I does not have the same power as the 22re, a bit less. It is really working once I get over 80km/h so I added some fuel and set my boost up to 14psi (from 10). I will see how that is next time I take it out. I think this engine would not work so good in a Runner, TDI would be better.

UPDATE:
I have been driving it to work this week. I have to go 60km each way down a freeway. I can cruise at 100km/h and can accelerate up to about 110-115 without much problem. At 100km/h the engine is at 2800 or so (4:10 gears).

Off the line I have to ride the clutch a bit more then normal until the boost starts to come in. This is around 1400-1500 then it is good. I am having to adjust my driving style because the power band of the diesel is very short, 2100-2700 it pulls very well. I also have to shift faster because if I let the boost fall off between shifts it has to work to get back to the sweet spot especially between 3rd to 4th shifts. I can't lug it like the 22re, except it first gear.

I turned the max fuel screw in until the idle went up 300rpm and then adjusted the service idle to get the idle back down. I also adjusted the waste gate and am now peak boost is around 14psi. I can get peak boost at about 2100rpm. There is a long hill that i have to go up and my exhaust temp will just start to go over 1400F then I let off a bit as I have read not to go much past that. That is holding a steady speed of 90km/h.

The engine does not get hot and actually runs cooler then it did in the car. This may be due to the amount of room under the hook and the size of the oil cooler that I have on it.

As for milage I have not put a tank through yet but I can tell you right now that it will be very good. I have gone 240 km, and if I corrected for the 31inch tires that is a 10% increase so I have gone actually 264km. I am just at a 1/4 tank used (very happy). With the 22re I could get 550km(uncorrected) per tank best.

just thinkin' here flash but if you were to put a different turbo in there you might get a larger boost range and less fall off when shifting...
I have no idea which one you could switch to though...
you could also try propane injection...
that long hill is the climb up from 9 to 88 right? lol

Flash319

The larger turbo would actually delay boost more but would allow more for higher boost. I don't need anymore, as I don't want to blow head gaskets. The turbo I have is small and thus the peak boost so low in the rpm range (this is good for a truck). This is just how diesels are. I just need more gears. Eaton Fuller 15 speed............ The problem is that the engine is not big enough without the boost. I need the peak torque to move the truck.

The hill that I am going up is the one going north out of gasoline ally on highway 11.

Flash319

Half a tank and I am at 440km corrected from 400km on gauge. Oh yaaaaaaaa.

If you can find a R151F that might help you out off the line. Its got a 4.31 1st gear and a slightly taller 5th. Its a little too short for me. I'm suprised it has such a short power band, I thought they would rev in the mid 3000s atleast.

Flash319

It will rev well past that but it just feels flat once I get past 3k. If I screw with the govener I bet it would pull longer but then my milage would go down. I am happy with it though.

aviator

That is a fun little hill flash...
try #10 climbing up Caledon 'mtn.' towards O-ville. I hate coming up that one in the 5t... always end up a crawl even geared down and empty... lol
if you changed your axle ratios you'd be able to stay in the power band longer... of course your mileage would change...
looks like you're going to get about 880 a tank... I hate you...

Flash319

Ya I know that hill, thats big and long. As long as I let off a bit going up the hill I can keep my EGT under 1400F. If I held into it, it would go way over that, not good.

Well my tank got smaller at the end or I started getting a little heavy on the foot (getting confident with her). I am half way between 1/4 and empty and I am at 650km, corrected that is just over 700. When I fill up on tuesday I will have a MPG number.

hmmm interesting read flash. its also funny to hear you and aviator talk about the roadways. i grew up in caledon so im quite familiar with the areas youre talking about (i used to drag race traffic on my dirtbike on the highway 10 mountain when it was under construction for widening)

anyway, im going to be moving to barrie for school in the fall and the idea of a diesel swap into my yota is delicious sounding. if i end up just keeping my truck stock, having a yotatecher near by for advice and yota support sounds good too. id love to see your truck though! awesome build

Flash319

Sounds good runt262. I have lots of parts and crap too. If anyone wants to check out the truck just send me a message.

aviator

Yeah I've noticed that too... the top half always seems to have more ks in it then the bottom half... you'd think it would be the other way around once you shed the weight of the first half would'nt you?... just one of those strange things in the universe....

on keeping it cool... there was a thing I saw on the web some place about a cryo-freeze system to increase the efficiency of the intercooler... it was basically a loop of metal tube you attached to the front of the cooler and connected to a tank of ? with a solinoid[sp?] valve when you needed a shot of cooling you just hit the button inside... might bring down your egts a bit on the long hills by supercooling the intake air...

aviator

Welcome runt...
you need to get to know Shane over at Toyworks in O-ville... definitely one of the best yota mechanics around.
I'll pm you his contact info... BTW flash Shane might have a cab kicking around.

Flash319

I guess an intercooler would help a bit. I am running stock Jetta config with no intercooler. Maybe I should look into finding one. I just hate having even more hosing under the hood.
The gas thing might have something to do with the sending units. I don't think they are very linear.

Sounds like the diesel is doing quite well. Just sucks your EGTs are up. I've got a cooling problem with mine but it is keeping the motor itself cool on long climbs. Your getting some pretty impressive numbers for mileage there. Just a little more than me. I'm about 230 miles at half a tank or 370kms. I'm just revving too high on the highway. Need taller tires. I'm planning an intercooler setup very soon here so I will let you know how it goes on mileage and keeping things cool.

Also about the gauge I find that it goes faster in the second half of the guage. My needle doesnt move off the full mark till about 130kms or so on average. But once it gets below half it starts to go quite fast and once past 1/4 you better find some fuel.

Flash319

My gauge does the same.
My engine is staying cool so I am glad for that, just my EGT's get up there if I hold on it for 30 sec or so. As soon as I let off a bit they drop.

I am running 31"s with 4:10 diffs. Most of my trip to work I am sitting at 2800rpm at 100km/h (60mph).

Let us know if that intercooler does anything. I have read a lot about them but am not sure if it is worth the hassle. I would also think that it will cause a bit of a turbo lag depending how big it is.

Just spent the last hour reading the thread. Now I know that I want a diesel in my '87 4Runner. Gives me a lot to think about. I might try to locate a Toyota diesel first but the VW option is looking very good. I am running 33's with 4:10's and a 22re right now so I don't get gas mileage any more. I drive it about 120 km a day to work and back.
Maybe I should just get a VW and drive it daily and keep the truck for weekends and offroading. It would be a lot less work.

Flash319

Well I just filled up today. Looks like my milage is 30MPG. Thats a mix of highway/city.
Zombie: I don't think you would like the 1.9 in a 4runner. It feels about the same in the truck as the 22re but I think the weight of a Runner will kill it. I think the only one to put in a runner would be a TDI. Check with Spulen(?) on that one. He has a TDI in a Runner. 33" tires would be imposible, maybe with 5:30's or something but then you would loose the point in putting it in------gas milage.

It's the gas mileage that is the problem. My company moved to a new location in Mississauga, they were supposed to move to Milton and I built the truck assuming a Milton commute from Guelph, no problem. Now it's twice as far away with all the stop and go traffic. I don't have any more parking available to use at home sofor now I am stuck. Not getting rid of the truck though.
