Have them bead blasted or hot tanked then hit them with a coat of high temp paint if a little surface rust is going to annoy you.

The first two were journal bearing and the orifice fittings installed by the turbo kit manufacturer (NOT AGP) were sized wrong.... Replaced those with CEA Ball bearing turbos of the same 67/66 size, and proceeded to blow those up from over-spinning them... They were too small for a 427 moving crap tons of air... at least over a WOT mile pass.... Rebuilt the entire kit with 76/75's, all custom in house fab work and never an issue out of the Precision turbos.... We spin a 417 (6.8 - 6.9ish liter) to 9k RPM's with them and have been to 27 lbs of boost, headed up to 35 lbs of boost when we get the rest of it sorted out... IAT's are awesome compared to the 67/66's... as the bigger units don't have to work near as hard...

My comment was more directed at the mention of the precision turbo quality... Improperly engineered or operated, anything is subject to issues... My 76/75 Precision Turbos are fantastic.... Having said that, I can post up pictures of the blown turbos...

AGP kits come with Garret Turbos and I'm going off 2 other trusted authorities that Precision had issues but I don't build Turbo systems for a living so my opinion is moot.
However, I do find it odd that you chimed in to show your blown Precision Turbos to make a statement that Precision makes a great product but maybe I am not understanding what you were saying?

He's saying the turbos need to be selected right for the application.
Using baby turbos for a mans job, will never end well, although some of the smaller precisions do seem to be a bit more fragile in terms of feeding big engines. Over an 1/8th, over 1/4, some messing about on street will never push them as hard as full WOT for a mile though. Which again just comes back to choosing the right turbos for the job in hand. |

Plus, precision was bought out by another company last month, so who knows how that will effect quality. The company that bought them isn't exactly known for high quality turbos.

And yes, I was making two points posting my blown precision turbos while defending them... One... Use a trusted known design company, i.e... AGP... Two... Use proper turbos for the application. The first set, journal bearing and the wrong orifice... Piss poor quality control by the kit builder, not Precision... Improperly sized for the cubic inches... Wasn't warned about this... Two, make damn sure the turbos are big enough for the application, without going so big you can't spin them up.... As Stevie mentioned, smaller turbos will hit harder and faster for 1/8 mile or 1/4 mile hits and lots of play time on the street, none of which compares to a 27+ lb boost WOT pull for a mile... This is where trusted companies like AGP come in... It's their bread and butter...
