Hey guys,

Today while installing my front mount intercooler I noticed that in the pipe that leads from the turbo to the cooler there was a film of oil. ie, Put your finger in and it comes out black.

Now I'm positive that means my turbo is on the way out. Am I right? How long do you think it will have left?

I decided not to boost it anymore than it is already (only set to 10psi) to try and keep it from dying too soon.

Also, what kind should I replace it with? I'm looking at keeping the internals, and injectors of the engine stock.

wil..

This could mean:

1) Turbo oil seal has blown.

2) Piston rings have gone.

Get a mechanic to check it out, and after you check your turbo and if its alright get a Compression test on your cylinders.

Its only around $110 for a new oil seal in your turbo, so no need to replace the whole unit. If you change to a bigger turbo you will have to have the surporting systems to go with it. eg: afm, fuel pump, injectors - to be safe and ecu to get it tuned correctly.

If its your pistons rings that are shot through, Its time for a rebuild and some forgies :D.

:D

hope that helps...

So it is relatively normal? (It was like a thin film of oil in the pipe. No oil came out of the intercooler)

Compression should be fine. Had a compression test done 3 months or so ago, and all was good. Also made a decent 167rwkw @10psi (w/ just full 3" exhaust, and ebc) at the Skyline Dyno day at UAS a while back. So hopefully the engine is still ok. I don't drive it that hard.

So it's only $110 to get a new oil seal? I was told more than that... hmmm.

Are there any aftermarket turbo's that are the same/similar size to the stock R33 GTS-T turbo but ball bearing? Also what's the average cost?

If theirs no oil in the cooler then thats fine. I was more thinking when you said fingre is black with wet oil that their was a lot more of it.

Steve,

I would'nt think a fairly standard skyline would need a oil catch can. You would only need one once you start putting big turbos and going for max power, As your car would be running a lot hotter and oil will be thinner and then going into catch can.

I'd still be cautious and if it gets worse get it checked out!

:D

      Alcon TA6 Calipers on R33 GTST - Flexing

      By Sydneykid · Posted

      Probably too late to reply to this, but worth a try. It's not calliper flex, the calliper as a whole is moving so it has to be calliper mounting bracket flex.  Calliper mounting brackets are designed to stop the calliper rotating, they don't need to be designed heavy duty to stop the calliper moving in and out.  Whatever it is is not the major cause of poor pedal feel, the outer pistons are moving towards the disc rotor the same amount as the inner pistons are moving away from the disc rotor.  Hence no change in fluid usage, what extra fluid is needed to move the outer pistons is recovered from the inner pistons. For a calliper to move as a whole by far the most common reason is the rotor is not perfectly centred in the calliper.  The first thing I check is that hub face is perfectly clean, bare metal, where the rotor hats contacts it.  Then I check the that rotor is firmly held in place by at least 3 wheel nuts (or equivalent). If all of the above are confirmed to be in perfect alignment then I would check the piston sizes and ensure that the 3 inner pistons and 3 outer pistons have matching diameters (eg; 28/32/36mm).  I have seen a no name 4 spot calliper that had 1 of the 4 pistons a different diameter. Maybe I missed it, are both the callipers exhibiting the same problem? I would remove the transfer pipe and inspect it to make sure that there are no restrictions. Maybe you already have but if not I would return them with the video and have them confirm all of the above.   Hope that helps Cheers Gary

      If you have the original log book and it didn't have a chassis number quoted, then no money required.  I have "rechassied" a number of race cars, no problem as long as you have the original log book.   Cheers Gary

      Question about BoV on RB25DET NEO

      By Yeetus · Posted

      Well the good news is that it won't run any worse with an atmo bov than it does with no bov, I've owned a few Nissans over the years (r32, s15 and now r33), the stalling issue caused by a bov or no bov while still having an afm is easy enough to live with, most people get used to driving them and just feathering the throttle when you come to a stop to avoid it stalling. Changing to a proper ecu with a map sensor is ideal but in the short term I'd just slap in the bov if you really want the whoosh sound. I looked into the pass through type maf like the R35 one above but decided against it as the amount of oil and crap flowing through the hot side would mean you'd have to clean it often to keep it working.
