Does that mean it's mated to a Merc trans? I hate Merc transmissions. Major bitch to work on.
Compound turbo possible?

Currently, but was just rebuilt before I got it. Once I destroy it, i will be switching to a c6.

Nice! My Cummins pulls over 70 lbs boost with my new billet turbo and supporting mods. Transmission is the weak link for sure even with the billet shafts and triple disk torque converter. I want to buy the Cruz diesel but needs to be with a manual. Why would Chevy not offer in a manual?

Not a huge bt4 fan. Way over used. Not saying its a bad engine just that there is other more efficient engine out there.

I would like to add that I prefer diesels with automatics. The 04 5.9 6 speed I had for a short time sucked pulling our trailer. You would be pulling a hill and have the turbo spooled and shift and loose the turbo and the thing fell flat on its face. The 05 automatic I got after it with a automatic was soooo much nicer. Never loose the turbo, just mash the the gas and go.
But that is just my option

Good point.
But the diesel cruze is just alil more geared to maximum mpg than pulling anything of weight up a hill.

also a dinner prick
This is probably the reason. If only 10% of your market wants that configuration, why waste the money to be able to offer it?

I have been a manual.driver for 32 years and it is very likely my next car will be an.auto. the new automatics with manual mode aren't the horrible slush boxes I grew up sneering at.

Very true. Its durability and repairability that concern me more than anything. Its hard to get a torque converter to handle a 100% increase in torque on any vehicle. Same with a clutch, but they easy and not as expensive to replace.

Yeah they're noisy old school but a good size at 3.9liters for most medium to full size applications. Other than 4bt the vw diesel is one of only other options for diesel swaps without a computer that I knew of.. Tell me more about this Mercedes 5cyl diesel. Is it comp controlled? Displacement, hp or tq?

I bought a samurai that needs an engine, was looking @ 4bt and like them, but they're so heavy! Way overkill for a suki, but I kinda need a bit of the way to much in a toy like that

Other reason I dislike the bt4. You really got to built up the suspension for them to handle it. My I5 is as much as the v6 I pulled out of it.
Don't get me wrong. In a 1/2 ton build this would be a different story
Like I said. I'm a huge Mercedes diesel fan. The om617 is a super reliable motor with alot of the engines at anywhere from 500k-750k miles and have never been apart. Gotta love German engineering

back to compound turbo 1.4s.. clip the turbine and or port the wastegate would allow more flow thru factory unit. Has anyone measured the drive pressure an a tuned car with stock exhaust? Maybe as long as the compound setup was only used in full turbo back, cat-less setups on e85 and less than 30 psi it could very well maintain the same drive pressure many of our cars are already seeing with the increased exhaust flow of the tune and the bottle neck of the stock exhaust. There's no math or evidence on my statements just a rudimentary understanding and some experience from multiple turbo projects. No doubt about it the turbo upgrade rather than compound is looking better all he time. They need to make a turbo upgrade kit that is turbo, manifold, downpipe sold desperate, and stock intercooler and mate to current intake setups easily.. that's whole 4,000$ kit is nice but too much to bite off in one chunk for Me and most people I think.

With a few performance parts what's safely available out of the I5 power wise?

$4000? Are you getting that figure from endtank? It hasn't been actually tested, so it can't be valued at a $ amount as far as I'm concerned.
A flanged stock mani turbo kit should be less than $3k.
Unfortunately piecing it together with existing aftermarket parts won't be likely. An external BOV will need to be added, and the downpipe will need some relocation. Some money could be saved by sticking with the stock I/C.

Well this is what mine has done:
Turbo brake delete
Waste gate delete
Egr delete
Light pump work
And I should be at 190hp and 300lb of tq ish. But it's a higher rpm diesel then most. I had it set to 4500 rpm redline when I modified the engine. Turbo dies shortly after that.
All in all its a ticking time bomb pushed north of 250hp it was built to be reliable with in a Hp range and that it does very well.
You can mod the 606 north of 450hp with no issues but I came across the 617 first and at a good price
And I'm ok with that. I wanted to build a daily driver not a race truck.
