Thanks guys, things seem to be getting a little strange, slight deformation on the exhaust side blades, intake blades are perfect, zero shaft play.

That's the thing, it's not an old turbo, it's got less than 1500 miles on it when it went out. Anyway, I ordered a 40 micron filter from XRP to replace the 10 micron filter that comes in the IP&T kit. Now just debating whether to stick with the 16g or upgrade to the 18g....

Welp Brian at BNR has the turbo, wants me to get a sandwich adapter and a new oil line running from it? Who in the hell makes that kit? Then he tells me I need a 50 micron filter for the IP&T kit, I told him I ordered the 40 and he said "oh that's ok then." Then he stated "someone used the wrong clip on the actuator and it's binding up, so that was likely the wastegate issue." Dave only added that clip after the adjustment, so it wasn't working right with the correct clip either.

 

 

Then he said the turbine had touched the housing on both intake and exhaust and could have been a bad bearing from the beginning... Then he said to pretty much pull the OCV's and avcs line to confirm proper function and pretty much get a compression test cause it could be my engine that caused it. I explained again the the VF46 I pulled was flawless, no play, filters clear, old lady driven and maintained at the dealer etc, so how would I all of a sudden have a engine issue?

 

So from the sounds of it the original turbo was bad right out the box, but now I have to go spend all this extra time and money to fix something that was bad to begin with just to confirm it? WTF. Not really sure what to do at this point...

Added the killer b pickup and oil baffe as well as completed the timing service and added a mishimoto sandwich adapter.

This was my first time doing timing, luckily I have a good friend who confirmed I properly set everything up via video. I used "Meaty's Timing Change" on NASIOC and that was helpful.

 

A couple of tricks:

~To reinstall crank pulley, clean mating surfaces well, put some clean oil on there with your finger and it will slide on with ease.

~Do not put oil on the crankshaft bolt, just dry torque to 100ft/lbs

~Make sure you get all the bolts off water pump, you need to remove this small rubber gasket to keep debris out and put it on your new pump before install.

~Water pump comes out by gently prying on the left side where the above rubber seal is.

 

That's all I can think of at the moment.

So over the last 2 weeks after my turbo failure I have done the following:

~KB Oil Pickup and Baffle

~OEM Timing Replacement

~Flushed Rad Fluid and Burped System

~Added new custom 16g (will have thread and more details later on when I have broken her in)

~Flushed oil system with new filter and crap 5w30 for 15 minutes while looking for any leaks, issues

~Oil change with new OEM filter and Schaeffers 5w40

~Installed AEM UEGO Gauge, idling at 14.5-14.8

~Made custom oil feed line from here: http://shopping.kinugawaturbo.com/turboaccessories.aspx

I had that same plug in my 09 LGT! Hope the repairs/replacements yield a happier car, when you pulled the OCV/S was there any signs of debris? Or in the inline filter? I ask only to add to my knowledge base of "what to check if..." :)

There wasn't anything in line, the failure was a 100% due to a bad turbo, more specifically a chinese manufactured center housing, a bend shaft to correct too large of manufacturing constraints, etc. Over 500 miles on the new JMP turbo break in and I have no issues what so ever. But he rebuilt it from scratch pratically. I do plan on writing a good review on my experiences, oil feed lines, filters, etc after my dyno appointment and next oil change.

 

Had to move my dyno appointment with Cryo back to 8/5 so I could get my turbo inlet installed. Next up new brake pads all the way around and a couple engine grounds.

Ok, so a little update, having some quirky tuning issues building boost. We could also smell a small exhaust leak, thinking my up pipe may be cracked, again.... Anyways, picked up a used Fast Motorsports catback exhaust that should help with the restriction along with a KS Tech air intake. I will go through and inspect, retorque the exhaust to spec from the headers back. Possibly replace the uppipe n the process.

I think there's more power there, just need to get it dialed in.

On the upside this is the first standard 16G/vf52/vf48 LGT I can remember hitting over 300hp on our dyno on 91oct. That's no small feat, just gotta figure out where the restriction is and why such late boost. We checked wastegate preload, we are maxed from a tuning aspect to build boost so it lies deeper.

KS Tech intake on the way, with heat shield and going over to the exhaust shop Friday morning to see what the retro fit will cost on my catback.

 

After that I will inspect my uppipe to see if it cracked... AGAIN as I had it re tig welded last year before the stage 3 tune.

 

Either way I'm pleased and look forward to see if that helps open her up and combat the restriction issues. I think she could reach 320whp.

It doesn't fit with the GS Splitter and didn't want to cut it up.

 

The trimming is really minor and I don't think anyone would really notice if you ever switched back to all OEM, if you ever sell.
