R33 GTR Mamba Oil feed /Water line kit

[Gojira95]

Hello All, 

I have a stock 95 gtr vspec.

I wanted to simply know if the turbos need to be removed if I am replacing the oil and water lines or can I just swap out the lines. 

Your guidance is appreciated.

Best guidance is that unless you have an oil or a water leak from the existing lines save yourself the trauma of replacing them with something that wont fit anywhere near as well.

Why are you replacing the lines?

[Gojira95]

Until I can get it on a lift to ultimately confirm, there is an oil leak from the current lines around the rear turbo area. I put it on jack stands to get a closer look.

It only happened once when driving from car wash and two very small drip spots on the last warm up. No leaks or drips when sitting cold in the garage.

I'm hoping I just need to tighten up the connecting ends on the solid lines when its on a lift. Otherwise,  I have been shopping the kit. 

I just bought the car and anticipated some form of immediate maintenance for a 25 yr old car. I wanted to keep it stock and streetable for now. I presume if I have to remove the stock turbos I need new turbo gaskets, coolant, etc., so I wanted to make sure if the turbos needed to be removed or not.

 I have heard this job can be a pain and I dont wanna spend un-necessary cash.

Job is a massive PITA and you would be well advised to pay someone to suffer it for you!

[Gojira95]

Ok, advice taken.

I will price out the labor to get an idea.

@GTSBoyDo u know if the turbos need to come off though?

 

[GTSBoy]

I don't know for sure, but I'd expect you have to do much more disassembly than you'd like.

Best bet is find the leak and if, in the unlikely event, it is the line and not something else repalce it with a stock part.  But is likely to be a washer or thread.

[Gojira95]

Thanks for the feedback guys. 

I'll troubleshoot asap and let u know what I find

If they are leaking from the banjo fitting just back it off a 1/8 turn and then tighten again. They run copper washers and these can reseat when you do that.

Both lines into both turbos are prone to have the flare fitting seize onto the line so be very careful if you decide to try and back them off and reseat them as you can twist and break the hard line (this is also a likely failure point on the hard line if someone has been in there before you).

I actually don't know if you can replace the lines with turbos on, I've only ever done it when I had the turbos off anyway. Even if it is possible to do with the turbos in place it may well be quicker to do it with them off.
