rb26deet32 Posted April 2, 2010 Report Share Posted April 2, 2010 I'm replacing my turbo this weekend and I was just wondering if there is any specific way to break in a new turbo. I've always heard that you should disable the fuel/ignition and just turn the motor over for about 10-15 seconds 3-5 times so you get some good oil circulation. Then you turn the car on and let it idle for about 15-20 minutes. Then you baby if for 100-200 miles. That's what I've done before and it has always worked. But the thing is I've always had cheap as turbo's. And my new turbo is worth about as much as my car. If anyone has something to add let me know. The turbo should be getting here tomorrow or the Saturday. Thanks. Brent Quote Link to comment Share on other sites More sharing options...

Mike C Posted April 2, 2010 Report Share Posted April 2, 2010 I've never "broken in" a turbo in any way, whether it be a standard journal bearing or a Garrett BB CHRA. Quote Link to comment Share on other sites More sharing options...
rb26deet32 Posted April 2, 2010 Author Report Share Posted April 2, 2010 I was just talking to a buddy and he said something about changing oil to non synthetic motor oil for the first 200 miles. I don't see why I would want to do that at all. It seems like that would just be stupid to put in oil for break in that I'm not going to be running for the life of the turbo. Though, I would do that if I were breaking in a new motor because of all the metal shavings that new motor create. But I wouldn't think to do that with a new turbo. He might have misheard something and got the two mixed up. Thanks. Brent Quote Link to comment Share on other sites More sharing options...

Guest Spam Posted April 2, 2010 Report Share Posted April 2, 2010 You need to prime the turbo first and foremost. You do this by putting the impact on the crank bolt and make the oil pump spin until the turbo is fed. Then just run the car normally. I would cycle the car on and off for a 15 minute session. In between, just check you have no leaks and you are getting adequate flow to the turbo. After that, drive it like you stole it. Quote Link to comment Share on other sites More sharing options...

Wouldn't turning the car over with the ignition and fuel pump fuse removed do the same thing? Like if I were doing a compression test. That's what I planned on doing. If you've ever heard something bad about that let me know. Because I really don't want to waste $2k for doing something to save a little time. Thanks.

Guest Spam Posted April 2, 2010 Report Share Posted April 2, 2010 Sorry. I thought i read running it with the ignition in. My bad. Yes, that would work the same way. I usually do it that way so i can see when the return tube starts to drip so i can stop impacting it. Its just easier that way for me. Good luck!

jeffro Posted April 2, 2010 Report Share Posted April 2, 2010 after using google for a meer 35 seconds, the first 3 answers i found all involved disabling the fuel pump and cranking the car via the ignition. Quote Link to comment Share on other sites More sharing options...
Guest Spam Posted April 2, 2010 Report Share Posted April 2, 2010 Im not disagreeing with you. But, i like impacting because the crank is only a foot away and i can see the oil line from the turbo. I unhook it and when it starts to flow, im done. But what he said is also good too. Its just preference. Quote Link to comment Share on other sites More sharing options...

Its just preference. That makes sense. Luckily I'll have a few people standing/watching as I finally get my car running so I'll just have one of them yell when they see some oil squirt out Reminds me of how I bleed my brakes. -Hook up clear plastic line to bleeder valve -pump brakes like a mofo -when I hear what sounds like someone taking a piss on my fender well run and shut bleeder valve:cool: It works 60% of the time, every time...

Stimmel1647545512 Posted April 2, 2010 Report Share Posted April 2, 2010 Best advice I have ever seen given here is as follows... hold it on the rev limiter for 10 min right offthe start. Quote Link to comment Share on other sites More sharing options...
hpfiend Posted April 2, 2010 Report Share Posted April 2, 2010 pee on it a little lol- to clarify, not a steady stream just a trickle... or if you aren't man enough for that.... disable the wastegate Quote Link to comment Share on other sites More sharing options...
Rotarded1647545491 Posted April 2, 2010 Report Share Posted April 2, 2010 Yes, ALWAYS prime the turbo with oil. But.... Forgive me if I am off base but isn't it about heat cycling, not just driving it easy for 100, 200, etc. miles? I was under the impression that you want it to heat up fully, cool fully, heat up, and cool a reasonable number of times to allow for the expansion and contraction of the metal and seating of parts and seals before you spin the shaft over 9000+ (arbitrary #) times.

CRed05 Posted April 2, 2010 Report Share Posted April 2, 2010 Yes, oil temperature has a lot to do with it. I never spool my turbos unless oil is up to temp. Quote Link to comment Share on other sites More sharing options...

AWW$HEEET Posted April 2, 2010 Report Share Posted April 2, 2010 Needs extrude hone mod. Bolt up turbo but fill with sand or media first. Turn it on and let it run at redline for 10 mins. This should remove casting marks inside and provide for better flow. Quote Link to comment Share on other sites More sharing options...
