I can't remember the weight but I believe it was 4100 to 4200 when I went across the scales with the yanmar. The gears are 3.73 and I have a bigger tire than stock. A 31.2 if I remember right. The alternator/ vacuum pump is isuzu and I did get it from ebay. The center banjo bolt is a oil feed for the vac pump. I can tell u how to wire it when ur ready. It's very simple. I got a few oil pans from Lenard's diesel in California. They are cheap and he ships right away Sam is a great guy to deal with and is very interested in these swaps. The turbo is great. It was just a cheap kkk k03 from a 1999 vw passat 1.8lt gas engine it builds boost very similar to fte's and the egts stay in check. It will hit 21 psi relatively easy. I still need a slightly stiffer governor spring I'm limited to only 2500 rpm right now. My trans adaptor is almost identical to fte's I don't have all that many pics of it.
thanks Dennis

You have 3 ports on the vac pump 1 for vac 1 for oil and another for oil/air return.

Here's a old pic. The center spade is unused. The outers are switched on and volt meter. My ranger pulls the volt reading from the fuse box so I have both wires going to the Same switched source. It charges at 13.5 volts and is internally regulated

I still have a question about the oil for the vacuum pump. This oil inlet gets full engine oil pressure? Then the vacuum port goes to the power brake booster and the rest of the system. Where do you run the oil and air pressure output into the valve cover? How much oil goes through there? Is there an orifice or anything to control the amount of oil it gets?
I am glad I asked before I started my engine with the alternator hooked up
thanks

The vac pump gets full oil pressure. The is a small orface in the the inlet for oil. It only recievs a small amount of oil every rotation. There's 2 very small opening on the vacuum impeller for oil. I have mine in the valve cover

Here are some boost numbers. I had to reseal a few drive pressure leaks.
20psi @ 2250
18psi @ 2100
15psi at 2000
12psi @ 1700
10psi @ 1500
4-5 psi @ 1300
2psi @ 1200
2psi @ 1100

Egts get a little high when lugging 1300 rpm @ 4-5 psi =1100 degrees and will climb if you don't let the engine rev. It has enough power to pull itself out of the low rpms and build boost this instant was in 4th gear up a step hill

I believe you have me mixed up with redvolece; I never had water meth or compounds. The yanmar was turned all the way up but didn't have enough to hurt itself, couldn't push egts above 1000, always kind of lacking in power. I used propane to compensate for the lack in power. And as with any drug propane gets addictive. By the end I was using 35pounds of propane and 30+pounds of boost. Only took a few nasty propane backfires and that was the end of her.

The yanmar would be great in a 2wd truck it honestly had enough to get on the hwy and run 75 all day it averaged out at 35mpg but I always wanted more. After I drove fte's ranger and redveloce's jeep it really made me realize what I was missing out on. With my current setup I could blow th doors off my old 1. The power is down low were I wanted it. I had to wind the pi$$ out of the yanmar for it to do anything. I don't believe the v2203 has piston squirters but I'm realy not sure

Mpg update. 374 miles x 1.08 is 403.9 divide that by 10.2 gallons at fillup is 39.6 mpg
not bad with a drive pressure leak for the first 150 miles on that tank
