I blew a turbo a whille back but was still forced to drive the car everyday....

Unfortunately when i removed the turebo to put another stockie one on, i found that it was the front wheel that had gone, and as a result a fair amount of metal had been ground off the wheel and the front housing.....with a few filings found in the intercooler pipes when i took them off....

My concern now is that metal filings have gone through into the cylinders...

My engine blew two weeks after i bought the car and i had it fully rebuild so it now has forgies, honing etc...

I don't know what to do, i think i should be ok as forgies shouldn't develop hot spots and melt as easily as stock pistons... and i can't afford another f-ing rebuild....

Just want to some advice as whether i will be ok or not.

If the filings got into the engine itslef, then any number of things might have happened. It'll act like sandpaper going thru the engine.

Scouring/Scratching of the cylinder walls would be the big one. Especially if the metal was small enough to lodge between the piston and the block.

If you start using a lot of oil/low on compression, then this would be the tell tale sign.

Who knows the damage done.

It would pay to pull all your intake component off eg intercooler, plumbing and even maybe intake manifold off and make sure it is all clean from more metal. I would be reverse cleaning your intercooler to make sure there is nothing left in that, as metal does not do engine internals any good at all. Don't matter if you have forgies or stock pistons, metal will not do them any justice. Not only do you have to worry about your bottom end you have to consider what all those little bit's of metal have done to your valve's and seat's. Only time will tell if it has done any damage, here's hoping it hasn't.

As others have said.

Clean the whole intake system including taking the plenum off just to have a look.

I would also have the head removed and inspected to see if there is any damage before driving more and doing more damage

IMO, you will not be ok.

rb26s get destroyed just by having a tiny bit of ceramic going up back through the exhaust valves.

If there are indeed metal filings in the piping and stuff, it woul dhave undoutably gone into the engine.

drain the oil and run it thorugh some fitler paper and see if you see any grit in there.

Pull plenum off, if there is metel shavings up that far you can guarantee they have entered engine. Dont make the same mistake and continue driving it as it will cause more damage. at the moment you will probably only be looking at a hone, re-ring & head service. leave it to long and it might be a bore and pistons. Kind of a catch 22 situation. good luck, i hope it is the latter.

Its like a compression test - they test the engine and can tell if it is internally damaged or not.

Take it to a good mechanic

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.

      The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
