BP turbo build/advice

solidus · 11-03-2018, 03:46 PM

I just went through this with the exapump. Check the exhaust , and also the intercooler. My wiring for the exapump got nicked during motor install. Had oil everywhere. Ended up having to soak the muffler in a bucket of gas to get rid of the smoke. Oh, and taking the turbo off is simple. It's just on the flange for the manifold, no need to take off anything other than oil lines and the lower charge pipe.

I took off the intake pipe at the main and didn't see any oil, I'm hoping it just shot int he exhaust. If so ill just get a new one, i need to put a cat in anyway to pass emissions. Gonna start next week, to much work and real life stuff. what do you guys think about the ats v ?

So with the issues you guys are having with the oil fed and scavenge pump why not switch to the comp oil less turbo

I would have right vefore I did the 6870 but I didn't even think of it till Sasha said something. Scavenge pump isn't really so much a problem as it is a temperamental bastard. First failure I had was from pieces in the system with my engine pop. Replacing it was easy. This last time a wire got snagged during the built block process.

None of that is the pumps problem.

Which is basically what I said. The thing with the pump is that it's one more thing to go wrong , and that wrong could come from any number of things unrelated to the pump itself. I'm not making stuff up I've lived it. With that said if it were that much of a big deal I wouldn't still be running the exapump. Going with a Procomp wasn't on my radar until Sasha himself mentioned it to me. It simply prompted the thought of the simplicity of the setup. But I will say that if I get a wild hair the exapump is a gonner.

There have been more issues with the Comp turbo than with the exa pump.

A lot of them have been install related. I would say that the COMP turbos are performing better than the standard Precision JB turbos the kit came with.

The other REALLY BAD part about the Precision turbos, is that the manufacturer blamed any/all issues on "oil contamination" which I always thought was complete BS. COMP on the other hand repaired issues at no cost, even when it was an install error.

I have a Precision 6266 with a brand new scavenge pump in stock, as well as a COMP 6767. The COMP is what I'm putting in my car with the build this winter.

Hey Sasha, what do you think the problem could be? Also how much would it be to get a cartridge if i need one?

Well, I would start by pulling the turbo, or at least the down pipe to see if the rotating assembly spins freely. If all is good there, check the oiling system, and ensure the pumps pulling vacuum at the turbo oil discharge side.

I haven’t had any issues with my comp turbo ... I’m at about 22k miles on it .. only thing I have noticed is you can hear the ball bearings at low speed and idle very faintly ... doesnt seem to affect performance or anything .. you can hear the turbo spin for about 20 secs after the car is turned off. And most research I can find on triple ball bearings people tend to say they that’s about normal. Not to imply that it’s better than an oil fed turbo but just the simplicity of not needing oil lines and scavenge pump to deal with is awesome

Yeah, that is normal. My Precision ball bearing did the same thing. Once the COMP turbo is broken in, it spools fast/hard. Mechanical efficiency is extremely high with these units.

So I took off the down pipe... Filled with oil. I look at the lower input on the inter-cooler and it has oil dripping from each joint. The turbo looks full of oil but it does spin, no shaft play. So what do you guys think should be the next step? Here are some pics for reference.

Same exact thing that I just went through. Turn on accesory power and see if the exapump is running. Mine had the wires jacked up during install or uninstall of the engine. Also afterwards oil was in the exhaust to the point that I had to dunk it in gas because trying to burn it out by driving was like a smoke generator on a tank.
