New turbo from the junkyard

[SilvrEclipse]

So you all know the 20g got damaged by the compressor nut so I was in the market for a new turbo. The 20g would still boost but spooled slower, had a few chipped blades and the shaft got a little bent. I wanted a turbo that was a little bigger than the 20g but on the cheap side. Decided I would go with a holset turbo. Capable of making good power and still spooling quick. Also very cheap. These turbos are off the cummins diesel motor and sell for around 250-400 used. These turbos are also capable of taking quite the beating. Diesels can run 40+psi. After looking locally and online/ebay I stumbled upon a few wrecked dodge diesel trucks in the junkyard. The trucks were wrecked so the motor was still good. Found a nice holset turbo that seemed to be in good shape. Also it was what i needed having the T3 exhaust flange and 3" vband exhaust adapter stock. Spent a few hours on it today pulling it off and ended up buying it for $45. It has 200k on it but only a tiny but of shaft play, which im sure is just cause it has no oil in it. Started tearing it apart tonight and cleaning it up, if everything goes as planned I will be installing it on saturday or sunday!

The turbo is a holset WH1c. 8 blade, 56mm inducer capable of flowing up to 52lb/min. Should max around 500whp. I will be using the stock 12^cm divided T3 housing which should give full boost a touch after 4k. I could use the dsm flanged bolt on housing which would decrease spool time by 5-600rpms but doesn't work with my setup. Enjoy the pics.

Badass... That'll be fun on the DSM... They make some crazy power on the diesels with those things...

Thing is massive!

(Nice triple post BTW)

Holset was installed today. Had to cut and reweld the flange on the manifold to allow the compressor housing to clear the radiator. It barely fit with this manifold. Also has to chop off my wastegate extention and reweld it a little bit higher. Overall it turned out pretty good. Took about 4-5 hrs to complete everything which isin't to bad. Have a few exhaust leaks but those will get fixed this week. Pulling the manifold back off this week to wrap the manifold with heat wrap, should help cut down on some of the heat in the engine bay. Also the manifold is starting to look bad with finger prints burning into the stainless. The compressor housing is not setup for boost reference yet so the wastegate was not hooked up yet. The turbo spools a little bit slower than I would have liked. 10psi at 4k then shoots up pretty quick. Full boost by 4.5k probably. I was still running 2" pipe on the hot side of the intercooler and didn't have enough 2.5" to replace it with yet so had to use a lowes plumbing coupler to reduce the compressor down to 2". Ended up blowing it off when hitting ab 20psi real quick so that will need to get fixed tomorrow also. Planning on doing some tuning this week and messing with timing some maybe getting it to spool a little quicker by pulling some timing in the spool areas of the map. Pics will get posted up soon.

Sweet deal man. I hear nothing but good about Holsets on Tuners. I'm guessing you didn't take the compressor nut off this time. Should be a nice setup once you get everything right. Post up pics soon please. I will have some updates on my Spyder soon.
I'm glad your keeping your lips lubricated in these cold conditions.

i really hope this turbo hlds up well for you.. its about time your luck changes

ps is your car getting dynoed? fb stalking

[ned032002]

That turbo cleaned up really nice btw. I can't wait to hear the hp increase from the new turbo.

[SilvrEclipse]

We were just messing around with the dyno yesterday. My car only put down 270whp on the 20g. Which obviously is wrong, low boost hp seemed accurate but the dyno doesn't want to read over 270 for some reason. Its rated up to 450 so there is something wrong we have to figure out with it. Tried putting a camero on it to see if it peaked at 270 also but had some issues and by the time we worked them out we didn't have time to run it again. Next week hopefully everything will be straightened out and ill put the car back on there. Its only at 23psi right now, need to finish tuning it, its running 11.0s under boost and I have pulled 5* timing that I need to add back in. Still pulls like a MFer. Ill put some pics up after class today.

Nope. I made 272whp on a 20g years ago. My tune/AFC/fuel delivery were all suspect.

[SilvrEclipse]

The car put down 340whp 312wtq about 2 weeks before that on 23psi. And that was with the 2.5" exhaust and cast manifold. That was changed out to the tubular manifold and full 3" exhaust before putting it on the dyno again. Both at mustang dynos BTW

I'm just pointing out that the number isn't "unusual" as HP ratings are MAX ratings. Hell, my SCM61 is rated for 600. I do not make 600.

Here are some pics of the holset installed. Still need to get some more wrap and finish the manifold and wrap the coolant line but its getting there. Need to install the new clutch and then hit the track with it. Going to max out these 650 injectors, still running 2" hot intercooler pipe that I need to change over to 2.5". That will have to wait till the summer tho, sure thats killing the top end of this car. Let me know what you guys think





Damage to the 20g wheel. Surprisingly the housing is fine, turbo could be repaired with a new compressor wheel.

[LandoAWD]

Holy hell that's tight fitting! Is it touching the rad?

[SilvrEclipse]

Not anymore, on the top of the compressor housing you can see where it hit a few times but I pulled the rad forward a little and now it has about 1/4" of clearance or so. Its very tight

I'm interested in what your coolant temps do with that bad boy. Sounds like you're thinking in that direction already, though.
