nothing wrong with that at all, you just have to love our ECUs.
edit: the vacuum line was likely from running my 1st generation MAF housing which I've dealt with and they all should be connected now.

Rick,
Thanks for the follow up. For now I think everything is good so I'm going to enjoy the truck and get a baseline for what it can handle.
Depending on my driving habits, I do foresee a Tranny valve body or rebuild one day.
Thanks for the help guys....here's a quick teaser shot. I just need to clean up a few things and build an air box around the filter now.

Looks very similar to the rig in my yard with a blown engine due to the turbo!
Alia176 and I are pulling it today for a full rebuild.
This is Clownmidget's rig that died and had it brought to my house for rebuild.
Ali and I will be pulling and tearing down.
Clownmidget flies in next week to rebuild it in my sunroom.....it works as a great engine rebuild location.
Should be a trip indeed!
I think he meant closed loop. Does it work well, does it stay 14.7 cruising etc.
The problem with after market turbo cars and cars that are turbo that are modified running a factory computer is that "sometimes" the turbo will spool early and the car will stay in closed loop trying to attain 14.7:1 air fuel at 4-5lbs of boost and that in NOT ok. This is one of the benefits of running the mapecu. You can alter the o2 factory o2 signal to "lie" to the factory ecu which will then trim the fuel in that area of the map and "make" it run the af you want. Usually cars will go open loop either with a load or TPS or some algorithm averaging the two. Load being airflow through the airflow meter. In that case you could go speed density and calibrate it for more fuel at that airflow and it will push it into open loop. Once you're in open loop, its all game, you can adjust accordingly. Sorry for the rant.
Anyway, being new to "these" forums I am amazed that these can just "take" a turbo like that! I've done lots of reading on some of the guys that have turbos and it just blows me away. Have a LOT of fun on your new turbo venture! I'd love to go for a ride up a hill in one!!
I'd really like to put a good logger and not just a simple code reader, on the factory ecu and see what's going on. Is it knocking? What are the fuel trims, etc.

Onur, Clown's truck was a 40th i thought, that truck looks very white in the pix.
Would love more info on what happened to the motor.
In preparation for the turbo, I have the HG done, new tstat, fan clutch and factory radiator replaced. I find in my driving habits that 5-6lbs is all i have to give for it to do what i want. My hope is that it'll stay reliable with those low boost numbers.
Wayneosan, there is definitely some catch up time on the AFR gauge when doing 4-5 lbs of boost. Maybe it's the sensor or maybe it's the ECU. I'll continue to try and educate myself on this and determine if some additional support is needed in the fueling/engine management area.

Yes, his previous 80 was a 40th and Refug's turbo went into it. This new 80 has a complete Safari turbo with intercooler and Unichip that were installed by the PO.
good gawd you got a horrible memory...
yes, my 40th had a Safari turbo from Aus (from a totaled 105 w/1FZ). It was sold to Reffug after he wrecked his truck that had the US Safari system.
that one is a 1995 with one of the Man-A-Fre purchased Safari turbo when you could still get it from them without the install.

Brandon, did you install a check valve in the line from the charcoal canister as is recommended in the Safari install instructions? PM me if you want me to email you the PDF just to read, it's not too much detail but might help.

Thanks for the info guys. Nice to see the truck will be getting fixed up.
Clown, I did install the check valve on the canister. I have MSGrunt's old homebrew kit. The kept the main pieces but tried to upgrade a few things while i had to the opportunity; removed silicone joints and had TIG welded piping made up to work around the dual batteries, etc, etc.
That fitting is a 1/8" BSPT thread. Here in the states we need to deal with that a little since our 1/8" NPT is different.
I used a 1/8" BSPT x 1/8" NPT adapter and the used an off the shelf "T"
