Tao, you might want to consider an oil cooler AND a sump extender to permit a larger quantity of oil to help manage temperatures.

When I first took my Zed out on a closed road for some serious hi-speed driving (I participate in a number of closed road events at Sandown, Philip Island and other places where we can use our cars to their design potential without the risk of Inspector plod seizing our cars), I hit oil temp problems straight away (within 4 laps actually - less than 12kms). If the oil temp rises above 137DegC, the ECU puts the car into limp-home mode (<4000rpm rev limit, cuts back on ignition, blah blah).

As a conseqeunce, I have had a Stillen oil cooler kit, and a sump extender kit fitted.

Despite what a Nissan dealer may say, this will not invalidate your new vehicle warranty, rather, you need to be in a poisition to confirm that the root cause of any incident is not related to these additions - the law is quite clear on this point, so you simply need either to have confidence in your own ability if you fit these yourself, OR engage a reputable automotive engineering shop to fit them for you.

In any event, as soon as you start to use big revs, that involves the cam tricky-gear doing its thing (which is oil pressure actuated), you start to subject the oil to a greater workload ... there are lots of posts on this subject.

Bottom line, you are safe for "normal" driving unless ambient temps are really high (well over 45 degC) AND you are flogging the guts out of the car - either really high average speed (not sensible in our nanny-state in Victoria and probably the rest of Oz), or you are attempting to break you own personal record on the climb up Mt Buller for instance.

Without the oil cooler, the highest temps I saw last summer in normal driving was 115DegC, which is a bit hot, but well within tolerance. The minimum specification oil in the book can run up to ~140DegC without too many problems (and hence this is why Nissan has programmed limp-home mode into the ECU at 137DegC oil temp). Using a high quality fully synthetic oil is cheap insurance in my view, as these oils will tolerate higher temps, and given that I take my car out onto a closed road to use it at the upper end of its design limits regularly, I have chosen to fit an oil cooler and a sump extender to permit a little over 6 litres of oil inside the engine) - all of which is designed to resolve the design flaw created by Nissan manufacturing the vehicle without an oil cooler in the first place.

Those with a 4-wheel drive bent might be aware that Nissan produced the first version of the 3.0 turbo diesel with a sump that was too small, caused oil temps to rise and eventually a hole would burn thru a piston (part of the cooling in this engine comes from oil sprays up underneath the piston to remove combustion heat). Since the sump was too small, the oil overheated and the piston ran too hot and melted a hole ..... solution was simple, extend the sump and put more oil into the sump, and use a larger oil cooler. There is a lesson here for those of us that use our Zed's at the upper end of its performance envelope ....

Thank for the insight, we had an oil cooler mid build as a lot of plz had oil temps as a stock car. I just received a call today to pick up my car, Maybd going to test it for a couple days and see what's going on. From what I heard it was just a bleed problem. I will ask indepth what was the prob yesterday. But can't wait to try it tonight.

Great news for all!

So can I take that as 100% confirmation of your appearance on Sunday? :)

Hope so, got a meeting on sunday, let me try to reorganize today

If you don't stay long for brunch, you'll be home by midday.

count me in, i made the meeting at 2ish:tup: so count me in

Has anybody done anything to get a little more sound out of the Stillen? When I was at the track last weekend my Y Pipe bolts rattled a little loose and it was drowning out like every other car there. I don't necessarily want it that loud again, but louder would be great. PLEASE don't tell me washer mod!

^hfcs

did you see my sig? got em already...

hi Guys,:hello:

I am looking for exhaust for my 2006 Nisssan 350Z and really keen on getting STILLEN 350Z Dual Exhaust System.:tup:

I just want to find out about ordering process. Did you order through stillen.com.? Do they ship to Australia. How much was the total cost?

Cheers
Praz

I agree with onefastz, i did the same mods on my new 2011, cat back and dual long tubes intake from stillen, ordered both from their website, as they had both systems marked down on sale. everything went together near perfectly, fit and finish are great. Super easy install, with common tools, love the looks, sound and the way the car livens up just before 4g rpm.

Hey Guys,

I'm reviving this thread with the hope that those interested have now all got their Stillen 370Z exhaust systems shipped and installed :)

I'm looking at getting one myself and I've been quoted USD$1269.61 (current web price) + USD$485 shipping to the airport (Perth).

Few questions....

1. Is this about the same as what you guys paid?

2. Did you have to pay GST on the import?

3. Where and how much did you pay for installation?

4. Any other problems/advice/recommendations I should be aware of before pulling the trigger?

Cheers in advance!

Don't pull the trigger yet. Post these questions at our local site (details in my sig) and you'll get some good feedback.

Not to go into detail but are you aware of the duty & taxes that you'll have to pay on top? You're in for a shock like the rest of us who imported our exhaust systems!
