I have a 200,000km old turbo from a VL RB30ET (assuming hasn't ever been rebuilt) I have found 3 cracks around the wastegate port on the exhaust housing. This means it has to be welded up and be used external gate only. Also has some minor shaft play up and down, more so in exhaust side. now Is it worth anything?, can it be sold for $50 to someone who wants a stock turbo with external gate? Pictures tomorrow. Thanks

the cracks are nothing to worry about, unless they are excessively big, same deal with the shaft play

the crack goes all the way around inside the housing. hope to get pics today

Thanks Does it boost any different. I was thinking, once it heats up won't the cracks expand & you'll loose boost pressure. I think. Does the boost spike or drop?? Some original photos have not been recovered yet.

I've never used it Bought engine like this Wastegate flap is missing, didn't come with dump pipe. I'm told if it gets welded and i fix the internal gate the cracks will eventually open again and and boost control will be ****house. So i was told i can weld the hole closed fully and use external gate. I want to buy a new turbo cause its too much money to get this rebuilt and fixed with either kinds of wastegate.

All I'm wanting to know is if i can sell this turbo for anything or is it for the bin? Pics: Some original photos have not been recovered yet.

mine is like that n I have never had a problem

yeah those cracks are common mate, mine had some cracks like that adn didnt have any problems, still going strong to this day on a mates car. it will be fine

can someone post a pic of the standard wastegate setup? cause i'm told it's done in the part that bolts on the back of the turbo. I'm missing this. How much engine HP are these capable? I've been told around 300.

yeah just the back of it so i can see how the wastegate actuator connects to the flap? (which i dont have)

thanks dude anyone else can take picture? still wondering the approximate power the standard turbo can support.
