I would order the CHRA they sell though but I don't read feedback on them so I'm kinda of sketched buying from them. The CHRA I was looking at purchasing twere the VTT ones ECS tuning has. VTT is a good brand I believe reading around the forums. That brings me to my other question, all these CHRA offer or have a better/bigger compressor wheel. Is there any point HP wise. If I stay MHD Stage2+ it's not going to provide any benefits right? EDIT: Well nvm VTT seems like it's 50/50... Last edited by TheMidnightNarwhal; 09-30-2019 at 09:51 AM.. |

If you fit a new core you don't need to balance it, if you strip and rebuild the old one you do. the flow test is for the waste gates, not for the flow of the compressor side. Also I worked for Garrett for 30yrs before they thought it would be cheaper to transfer their operation to the Czech republic...that was a fuck up for them.. but I'm sure you know more than me.

I was referring to you rebuilding them and the waste gates yourself, I do this for a living,, and have done for over 40 years, 30 of those at Garrett.
I think I will leave you with the experts that have no idea. but trust me, rebuilding turbo's without the correct kit is going to end in tears, and they will be yours. good luck. |

But I agree a rebuild from scratch might I am not comfortable with that but CHRA replacement looks easy and is what I'll do instead when my turbos stop boosting, or if they ever do. Right now it's just oil burning in exhaust. EDIT: I see your comment about wastegate and flow testing. Why is flow testing required if the wastegate arm/flapper is reinstalled in the same position as old. Last edited by TheMidnightNarwhal; 09-30-2019 at 11:45 AM.. |

If the waste gate flapper, arm and bushing are all re-installed in the same position, why is flow testing required? All the searches I do on the subject no one mentions flow testing required, even the DIY on this forum. |

Hypothetical scenario : Let's say you are content with MHD Stage2+ and your turbos are shot. Blowing oil, no more boosting full rattle. What do you do or buy? Again, not looking at doing more WHP just looking at running FBO Stage2+ reliably.

To be honest, I have tried to give you some insight, into what you are dealing with. It would appear the advise is falling on deaf ears!! if you don't understand what you are doing, leave well alone! or leave it to someone who does... bye.

Or you haven't confused it which brings me to the following comment; I don't get why someone gets so fucking triggered when you just ask them back clarification and questions so you can understand and learn yourself or why such things function. Like what a shitty attitude it is to have and immature it is. You're probably older than me and act like this, I'm baffled. I'm not ignoring your advise I'm asking you to clarify it. If I tell you to go jump off a bridge are you going to do it like that without any arguments or explanation? Of course not. If I tell you to jump off the bridge because there is some lava coming your way or whatever then you might do it. Like how is it so hard to comprehend this? |

Don't know about flow testing but I do know it takes a lot more than $75k in equipment to properly balance a core... My company only balances compressor wheels (it is then re-balanced at operating speed when assembled) and our newest unbalance measurement machine was $200k. That's just for the cold side.

In that case I would buy OE turbos and call it a day.

Somewhere between dinosaurs and 9/11 we had a snapped Garrett turbo shaft (diesel 2,5 I4)... since dad is a DIY w mechanical background he pushed our friend to do a new shaft... well they did not bother to balance anything, fit all in and there we went... it lasted some 100km and it snapped again :-) however there was plenty to learn from...
1st driving a turbo-diesel w/o turbo is a hilarious experience, it has funny sound and you are always waiting for a push that never comes, it is like a riding a tractor... 2nd there are no short-cuts when it comes to precise machinery :-) To each his own...
