1999 ranger yanmar to kubota v2203 swap
to those of you running the ko3 turbo..... how did you connect the oil feedline to the block? I have the line from the Passat but it takes a weird fitting, can I change the one on the turbo or what did you all do? also the line I have is almost all steel and I need a flexible shorter one
I brazed a barbed brass fitting onto the steel line and then slipped my plastic air line onto that held with a hose clamp. I use air brake line, like off an 18 wheeler, for oil line. There are pics in my thread.
I used a 1/4 npt fitting to a 5/16th compression fitting ( hard brake line ) and then a compression fitting to the vw line. I'm using the plastic air lane with reinforced compression fittings for the vacuum pump oil feed
So that I can get the plumbing straight to start with Oil Feed is in the center back of the Vacuum Pump and what looks like the top bolt is the Oil Return to the Valve Cover and the other outlet on the bottom is the vacuum to the Brake Booster Correct?
On the Oil Feed on the Vacuum Pump did you use a Banjo fitting?
And FYI We are all on Pins and Needles waiting for the outcome on the Dyno?

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

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

Hello everybody,
I guess I am joining the club....
I just cant let you guys keep all the fun for yourselves.
I noticed that there are a number of you located near me.
Rangmar
I live on Whidbey and have been following your-and others-V2203 builds. I have been saving money and am about ready to buy the engine. I noticed you commute from Darrington and work in Lynnwood from your thread. I have a 2001 Ranger 4x4 5 speed, pretty much the same as your set up. I am planning on turning the kubota flywheel to fit the ford pressure plate and building the adaptor here in my shop. Is there any chance I could meet you and take a look at your setup? I dont mean to impose but it sure would be nice to see one completed. Let me know, if you are busy I can understand that, especially at this time of year.
Thanks,
Dimitri

Update
Finally got around to changing the gov spring , now I can rev 3000 rpm. And I can get 27 psi of boost at 2700 rpm. Egt won't go above 1100 degrees and its way more fun to drive
Here are some specs on the k03 turbos I've found on another site
"I'm going to list each turbo model, what its fitted to, and its compressor/turbine specs along with maximum power (although these figures are probably in silly nonsense US wheel power, or perhaps borg-warners recommended power output, its still useful for comparison)
K03-005 - Standard fit on ALL cable throttle B5 1.8T's INCLUDING the 180hp AJL engine.
K03-029 - Standard fit on Drive-by-wire B5's and most B6 1.8T's bar the "190" model. Similar in specifications to the normal K03 fitted to Golf/A3's
K03-073 - Standard fit on B6 190 model. Similar in specifications to the K03s fitted to Golf/A3's
K04-015 - Not standard fit, Borg Warner turbo designed to be a direct replacement upgrade for the longitudinal 1.8T.
K04-020 - Standard fit on the TT/S3
FrankenTurbo F4h-l - hybrid, see 'zine thread.
K03-005
Compressor Size: 36/50mm
Turbine Size: 36/45mm
Approx Power Rating: 150HP
K03-029
Compressor Size: 36/50mm
Turbine Size: 40/45mm
Approx Power Rating: 160HP
K03-073
Compressor Size: 38/51mm
Turbine Size: 40/45mm
Approx Power Rating: 190HP
K04-015
Compressor Size: 38/51mm
Turbine Size: 42/46mm
Approx Power Rating: 210HP
K04-020
Compressor Size: 42/56mm
Turbine Size: 42/50mm
Approx Power Rating: 260HP
Franken F4h-l
Compressor Size: 40/51mm
Turbine Size: 42/50mm
Approx Power Rating: 240hp
So there we have it. Shows us the reasonably readily available k03-073 turbo is a nice upgrade without going to the expense of a new k04-015 too."

We are all on pins and needles on the Dyno Report?
So at 3000RPM does it sound like it is going to EXPLODE or as others say the Gerble is trying to escape
.
And Thank You for the information as always.
