Turbo is now on the truck thanks to Thomas and Mark at M&H. I have the vanes fixed right now Ill get the controller part of it worked out over the next few weeks. WOW what a difference, boost comes on late but when it does it spools fast, less over all boost, doesnt seem to get more then about 23lbs. I believe both of those things will be "fixed" when I get a controller on it. My egt's went up just cruising but under full throttle I couldnt even get them to 1200*. At 70mph I am at 800* and 1lb of boost, seems to be seat of the pants faster and I know I am getting more mph out of it now, was still pulling hard at 95mph.
After I get the controller on it and set up it will be back to the dyno to see what its doing. I will try to get some pictures of it in the next couple days. As of now with the vanes fixed and only driving it about 50 miles Im very happy with the upgrade.

Are the vanes fully open

[lectro_static]

No but they are I would guess 3/4 the way open maybe a bit more. Today I put the wastegate accuator on, now I just need to "T" my boost line and run one side over to the accuator and it should open as boost builds. I will hopefully have that done tomorrow but I have alot of "real" work to get done so might be a couple days.

Do you have any pics of the turbo on the truck

[lectro_static]

Sorry for the poor pics, these were taken with my cell phone

Got the boost line hooked up today, needs more tuning and less traffic to tune in but so far, max boost is about 28psi (less then with my H1C) lower over all EGT but a touch higher just crusing,(still have not been able to get it over 1175 but Im not towing yet either) less smoke but do have some and boost @ 60mph is now about 5lbs. It is still a LITTLE laggy but much better then before and I believe I can tune it out.
Who else has one of these on there 1st gen? Im curious about a couple things and would like someone to compare mine to.

[c12h26]

I have one on my truck

[lectro_static]

Yours is the one on youtube that whistles so nicely? Are you controlling it, if so how? What is the appx start setting on it,(about how far closed)?
Mine doesnt seem to "sing" as well as yours, altho I have not tried it with the aircleaner off. I have not heard it bark yet but would think it would if I snap off the throttle? Is there any way to tell if I am over spooling it? I do not have a drive pressure gauge. I THINK Im on the right track with tuning it, Im not sure it will do exactly what I was hoping, which is boost right off idle but less then 5lbs at crusing speed/light throttle.

I just closed it up a bit more and will try it out when I go out at lunch. I hope all Im asking/saying makes sense

Yea thats mine on youtube. I dont control mine i leave it fully open all the time. i dont think you are over spooling the turbo,with mine fully open i see 31 psi of boost and with nitrous it jumps up to 40 psi and yes i can bark the turbo if i let off to fast

[lectro_static]

I closed it up a bit more, spool is faster makes about 28psi, cruising at 65mph boost is between 5 and 6. Getting closer, I need to strap a video camera in there and drive it so I can make sure the actuator is pushing the lever like I think it is.

going to attempt the same swap on my 93 auto truck. Did the oil feed lines fit from the stock turbo? I'm running straight wmo and the temps and smoke are up! I have 40hp sticks and a denny T pin and a P/S cooler hoping this will cool it down. Any advise will help thanks.

The return oil was cut and a short piece of hose added, I believe the pressure side was the same but am not positive, M&H installed it all for me. They do sell an adapter for this install now.
I know my EGT's are down a bunch I could take it over 1300* before now I can just crest 1125*. I still need to play with the controller now I haze a bit under full throttle on the freeway, I think thats because the exhayst is opening up to much.

Just filled my truck and my MPG was 18, and I was beating on it trying to get it tuned in. Thats an improvment as before I would have gotten about 16MPG driving the same way. Very worthwhile swap IMHO

Glad to hear it worked out for you. I was planning on doing this on a non-intercooled truck with a very goofy-looking crossover pipe sometime in the future if the 60mm upgrade doesn't work well for me so I may be picking your brain at a later date.

Be happy to give you whatever help I can.

Something that I just noticed this weekend, going up this pretty good hill I will floor it, EGT's will start to climb, then they DROP over 100*. I have done this a few times now, thought maybe I was letting off a little but Im not, I believe that exhaust housing opens a little which make it more efficient and cooler EGT's. That sound right?

[mhuppertz]

We need an aftermarket controller for this turbo. I'm going to look into it because if we can get one of these to work right it will improve drivability and should be stronger on the big end at the same time. I was reading elsewhere that the late model VGT exhaust housing varies from something like 5cm to 25cm. With that we should be able to put a large compressor section on and not need twins. Just my $.02
