found it on youtube and the guy emailed me, hes got a few things real funky with his setup like the maf sensor and it looks like hes got no downpipe but its nice to see somone else complete a turbo setup even if its a low budget one
hes gonan email me back the info on the turbo and what hes using and ill post it up for ya guys, i also pointed him over to the site so well see if he signs up
too bad his MIL is on and it doesn't look that fast...looks like a lot of wasted time, money, and energy to me. I'd like to see time slips so I can change my mind.

Less HP than you would want to shake a stick at.
looks liek hes using a very small turbo, and aparently also stock injectors, i imagine its running lean as hell specially with the maf in the charge pipe.
he has it setup as a blow threw maf instead of draw threw
not to mention that tiny tiny intercooler hes got under there looks like a talon/eclipse side mount deff way to small
deff needs some work but atleats somone else got one up and running
I love the junkyard builds using what is freely available. That GT17 is maxed out and the IC is working hard. It is in the 40% efficiency range. Any more boost and they will overspeed it and possibly break the shaft.
I love the shot of the engine revving and that rubber accordion moving on the charge pipe. The smoke show was good too.
i bet boost comes in soon as he touches the throttle on that thing since that turbo is so small but it prolly kills the motor by say 4k rpms iirc corectly the gt17 has an obscenely small ex side on it
While were on the subject of turbos. Do they make any smaller turbos that have the varible vains like used on the ford superdutys?
They have a GT15V that flows about 200HP and a GT20V that flows a little more. They both have a variable vane turbine. The big thing is will it handle the exhaust heat?

a t3 60 trim would do wonders for that thing
It must be a blast to drive. I was trying to watch the boost gauge to see where it comes in. I couldn't really see it though. I think it is like you said. Boost right off from idle. Running the numbers it shows it should start making boost at around 1400 RPM and maybe a little lower. It must have full boost by 2000 RPMs. I like their "use what you got" approach.
i cant imageine how fast it spools cause even mine with a t3 .63 housing stage 3 wheel spooled up fast with a stock converter
now with the 60-1 and t3 .81 housing its a lil laggy if u just punch it from a dig but i like it like that keeps the back tires from being roasted off to bad
I have no clue on sizes, I'm not familer with turbos. But I know the one off a 6.0 ford would be way to much for the 6/60, likely still to big for my 5.7.
But I was thinking a VV turbo on a 6/60 would be really nice. Help add the boost low rpm, and possibly hold it a little longer.
hey i dont know much about turbos. but i wasnt rly impressed. i could smoke tires in my 97 saturn sl2.
now i was on you tube looking around http://www.youtube.com/watch?v=LuaInKgvqsA&NR=1
now that **** sounded hot. shame you dont see it run.

thats my car, look at my other videos u can see it run
Nothing wrong with blow through, except the heat can affect the readings. That's how I did the corsica when it ran 12's and broke 3 transmissions.
Junk, that almost looks like a turbo you need for your bike
I can give this guy props, though, seems as the MAF compensates fuel better than my speed density did, and I didn't even make the second run down the road haha.
So wish I was tuning BEFORE installing my turbo (both motors)

The 6.0 diesel turbo should be fine on a 660.
I'm running a turbo from a 6.5L GM Diesel on my 2.8L Nissan I6.
Now that I have the wastegate staying closed, like it should have been, I start to build boost before 2000 RPM and get to my current "full boost" of 14 PSIG (which is really only realitive my engine since it flows like crap), before 3000 RPM. With a better flowing head, it should start to spool a little sooner, and maybe build a little quicker.
You have to remember that diesels run at about half the RPM of gasoline engines.

I have a GT1752 here and some pipe to make a setup for the Harley. The only problem is I want to figure out the EFI setup before I put the turbo on it. I am thinking of going MS-II or Microsquirt. Over the winter I plan on reading up on each system.
I wonder how much they have into that V6 turbo setup?

I know they run at lower rpm because I own a 6.5TD. Thats why I figured it wouldnt hold up to the higher rpms. But I also know the 6.5 is designed to give boost at low rpm, and drop off at higher(to save mpg).
So your actually saying the 6.0turbo wouldnt be enough on my 350 then?

no it wont i think the 6.5 turbo works out to be a t4 sized turbo,i can look up the exact specs but u would need 2 of them on a 350

Heat has a big effect on the readings, that's the basic concept behind how the maf reads airflow. Artificially added heat would have a huge effect, I would imagine. Extra heat would make the sensor report that there's less air passing through it, even though there's significantly more under pressure. I'm curious what maf you were using and how far off the maf was in boost. Was it after intercooler?
I bet that home grown turbo is lean, but the stock ecm does a good job of pulling timing at higher temps. And with as small a turbo it has it might not be too bad off.

that maf looks like an lt1 maf which can be used in blow threw apps, the plastic ones that come on the 2.8 cars cannot be used that way they will not read anywere close to correct
Haha nice, i was just browsing the v6 forum and this is my car lol, yes my setup has alot of flaws, im 19 and a student so wokring low budget and have no experience at all with turbo builds suprise the car runs ! and still does today. Ive just ordered a fmu and will be looking for some 19lb injectors as the fuel system is curently bone stock. Im also gonna change the maf sensor and put it at the tturbo intake.. I got a problem tho, i dont think my maf is working anymore, i unplug it and it runs the same as when it is plugged in... how do i check if its the sensor itself or the wiring ? anyway ill post some pictures maybe or another video next week
Id like to know if anyone know how to test a maf sensor or if someone know whats the voltage supposed to be coming out of the connector wires ? i dint understand how the car runs if the sensor is not working because when i unplug it it dosent change anything.. thanks
This is another video i made with the rest of the footage of the turbo v6 running with v8 injectors (thanks Dale) and a 10:1 fmu. It was peaking at about 20 psi but the turbo is too small and would boost at about 15 psi constant and spinning so fast the air was really hot so not very efficient. Anyways this is the last of the footage before it started running like ****, i think a cylinder might be blown... i have a old 350 carbed with 3 speed tranny driveshaft and diff waiting to be build and installed so thats the next project. This was my first build i dindt know F** all about turbos but it was fun to do
last one.. i know ther not the best pitures, i wish i had some of the exhaust manifold but its basically the stock one, you cut a hole in it and run a pipe to the front of the engine.. i dont know if theres a better way to mount a turbo to this engine but this is the simplest way.
Do you have any tuning software or acess to a scanner? Check the maf flow with & without it hooked up. If it's the same it's probably not reading the maf. Codes?
no, i dindt have none of that, i ran the car with it plugged in and then with it unpluged and it ran exactly the same.. anyways dosent matter anymore im changing the engine i think a cylinder blew
Ha, I just noticed that after skimming over your last posts. 15lbs out of that little thing. LOL
