BCIV 400 with series 60 Detroit turbo

Just my opinion but that's kind of like a Frankenstein engine and I would stay away from it.

STC was an Improvement. It's silly to me that someone would remove that. I would not want that.

The series 60 turbo is tiny. Even the piping from the intake is tiny to that turbo. I know because I changed all mine when I pulled out my series 60 and put the big cam in.

In my own opinion who ever had that engine has done ridiculous things I would be afraid of what else they've done honestly.

No timing advance, a tiny turbo, God only knows what injectors are in there, I believe the camshaft may be different for the STC engines... the STC engines are also timed differently so when you look at that engine all you're going to have is question marks that no one can answer.

That's positively not what you want from a truck if you plan on working this.

Just seems like a terrible mess this guy made out of that engine.

Myself, I would completely avoid that.

 

No such thing as a series 60 turbo. There are turbos that was used on a series 60, but not a actual specific one. Numerous turbos used on them, and used on other engines. Building a engine is a combination of parts that work or have proven themselves for a certain job.

Low to high flow is a good conversation. Stc was problematic in past. It's really your choice, I'd dump it for reliability of top stop. Turbo, you need to understand why it's using a certain one. Air ratio is one. You can buy a huge turbo and have a slug also. Understanding why it was build that way, or what you wanna do with it is more important. And can't be built of fixed on a internet forum. Tried, tested, dyno tuned yes, not in forum.

 

If it were me I wouldn't even waste fuel or time looking at something like that.

I would instantly forget it and be glad that I did.

That engine is nothing but headaches and problems.

 

Sure, means zero. You bought something, you have no idea the build or CPL. Run a boost Guage. Pyro, and pull oil samples. Chasing Horse power or speed is expensive. Hope you understand this buying a non stock engine. What do you want? It's alot more than a turbo and fuel psi buddy.

 

Check the pump code tag on top of fuel pump, or if no tag for scribed #s. This may help finding cpl at least.
