Wow man nasty compressor. Much better flow on that new housing though. Im thinking the bits of alum in the turbine housing came fromthe compressor. I would go for a credit or something off that seller or smack him with a bad report. I always read negative reports before I buy anyhting off ebay.

Yeah it was gross, I could tell from the pictures before I bought it that it was nasty. They where right in there description that it did spin 360* and had minimal shaft play. For the $50 it cost me I'm ok with it ;)

Yes this new turbine will flow much better than the older one. I can also build my 3" exhaust right off the turbo without a transition.
 
Having no transition other than what is in the housing will be awsome for flow. I hate putting in cramped transitions knowing all the backpressure your going to gain. Sometimes you just dont have room and have to compromise. Are you going to run it straight through or do a resonator/muffler/urea soot burner?
 
Yeah this turbine housing will be much better.

I'm planing on running 3" all the way back with a Aero turbine 3030XL muffler. Hope to keep it quiet and not loose much performance, its a Lexus after all.....;p
 
If I ever get around to doing my swap, I'm going to look into adding the urea system.

Just so that I'm not "that guy".

Also because around where I live, "that guy" billowing black smoke from his diesel truck at every intersection attracts a lot of fix-it tickets.

Actually Urea injection its self as far as I can tell does not reduce smoke it only reduces NOx after its been created in the combustion chamber. Systems like EGR's and water/meth do the same but in the combustion chamber themselves.

The Urea systems I have seen are very complex and I'm not sure adding it to an older diesel will be easy or economical.

To reduce smoke the best thing you can do is tune it properly to no make the smoke in the first place. From there you could fit a diesel particulate trap, I have one and may play around with it a bit (not likely though). I think the key is having your fuel system tuned correctly and is what I plan to do with mine. Remember the big plooms of black soot are nothing but waisted energy in a diesel. It does nothing but give Diesels a bad name makes the greenies get all up in arms.

My Dad's 06 Dmax 2500 makes huge power and does not produce any noticeable smoke at all doing so. Its got a tuner I have played around with the maximize power while reducing smoke. Its also getting 23mpg hwy and 17 around town over the last 40k kms.
 
Bahh. Just feed the enging lots of air and keep your injectors clean. All those black smoke cummins guys clean up in the low rpms with compounds with small turbos. Keep your a/f lean and dont over rev it and its all good. I have a feeling your motor is going to run clean anyhow just looking at how the head is designed. Engines with low BSFC and high particualte emessions dont seem to go hand in hand in my mind.

Pretty good economy then for sure.. :cool::cool:

Yeah for a 6.6L V8 diesel pushing around a 7k lbs 4x4 truck making gobs of power its very impressive. It also tows there 12k lbs travel trailer like its not there. I doubt my 80 with this 4BD will do better economy wise when done.

As already mentioned, Urea is for NOx, not black smoke.
To keep black smoke gone you need a turbo that spools early (the TD04HL-19T should be perfect, just waiting for the first person to get it up and running) and a boost or altitude compensator that works properly.

Most trucks that smoke, smoke because a moron tuned them that way. Seriously, people do that.
 
My 1T does not have a boost comp only altitude. Its going to be interesting to see if i get much smoke off the line before the boost kicks in. I expect ill have a slight puff at first take off. I was thinking about getting a boost comp to cut the full at first tip in. My hope is the turbo (TD04HL-19T) kicks in fast enough to keep it to a minimum or none at all. I really do not want anymore more smoke out of it than a newer diesel/slight haze at full tilt.

With no boost compensator, your fuel plate inside the injection pump governor will already be cut to limit fuel to where it thinks it has boost. We'll see how that goes when fuel is turned up.

The 4BD2T boost compensator may just bolt on if you need one. I think they use exactly the same push-rod into the pump as the altitude compensators.

Yeah I kind of fuigured that had to have somthing to limit low RPM smoke, My next worry is the fact that this engine had the Laggy free float to begin with. So with the new turbo hitting peak boost 1000RPM faster maybe quicker will the fuel keep up?

If it doesn't, there are a few tricks we can apply. You just need enough room to remove the rear housing on your injection pump.

Well that depends.

1. Was smoke your #1 tuning goal?
2. Do you wear a flat billed hat?
3. Do you spell cummins with a "g"?
