Search... we we're talking about this just yesterday!

As far as I can tell, your options are:

  • ScottyM35 bellmouth dump pipe
  • AM Performance split dump pipe
  • Rex Kelway bellmouth dump pipe

With the exhaust, AM Performance do a complete solution, turbo back, that is interchangeable with everything else. So you can buy a Jap exhaust (Legalis, Blitz, etc) and buy a midpipe from AM, or buy the mid and cat back from AM. I think you can get a v35 midpipe too?

Scotty did mine and I was really surprised at the power gain and how quickly the turbo spooled up. Dont have any measurements but it was more than noticeable.

He was very fair on price and did a great job.

  • 2 weeks later...

My turbo just blew, so I'm thinking I might as well get a dump pipe fitted while its all in bits.

Who can get one to Sydney in the next week or so?

Thanks

I can get one but wont be back in Sydney till the 18th of March....If you need it quicker get in touch with Scott and you can push in front of one of the ones I have on order for upgrades fairly quickly.

Scott if needed push him in front of mine.

cheers

Craig

damn everyone is blowing turbo's from what i'm reading

how common is this problem? someone's told me nissan recommend replacing the turbo at 100,000km's.. i thought it was a bluff!

also scotty, out of curiosity, can you fill me in on how much your dump's are worth?

sound like a mod worth doing :P

If the turbo dies there is a good chance the oil feed restrictor banjo bolt is blocked (or lack of servicing over in Japan) causing the rear bearing to fail.

My dump pipe is a stainless bellmouth, it comes ceramic heat wrapped and includes the o2 bung, lower gasket and lower stainless bolts. It will also bolt up to the factory exhaust. I can do one for $450. :thumbsup:

quite resonable, when mine gets off the bost i shall be in contact with you ;)

also i remember reading a while back that people drill out the banjo bolt that feeds the oil from 1mm to 3mm, would this help save it? any DIY write up's? its the first thing i want to do to my m35

I agree Paul, I wouldn't be drilling it out too much unless you go to a bush core highflow. Just run a 1mm drill bit through the banjo bolt to clean it up. It is the thin oil line to the block, just in front of the passenger driveshaft output.

IMO Nissan have set the size of the restrictor for a reason and who are we to argue. While using the stock turbo keep the stock size, just remove the banjo and clean and inspect it.

They also gave us a throttle restriction, speed limited, crappy beep when we put the car into reverse, and dodgy cat in the dump pipe.

I'll be applying all the Aussie ingenuity I can find, and Leon will be applying all his DIY! Don't know about everyone else! :nyaanyaa:

And all of those things were given for reasons such as legalities and emissions requirements and so on.

I don't like them all either but when it comes to feeding the turbo the correct amount of oil, I'm sure they did their homework better than us. ?

Which is obviously why it can block up and starve the turbo of it's oil supply.thumbsup.gif

Yep; no design fault there...whistling.gif

How is that a design fault when you guys say it's from lack of servicing!!!

It's no different to the oil squirtters for the cams in my SR and the built in tiny oil restrictor in my BB Garrett turbo on it. Service the car correctly and they don't block up, don't service the car and they might. Or I suppose that's a design fault too!

That I agree with too....unfortunately the first owners of these cars were more often than not slack at servicing and like many things once a part is damaged it stays damaged or gets worse. drilling out that banjo gives you just a little more of a safeguard......putting the dump on and moving the cat further back is even more of a safeguard IMO. Regardless you are going to be up for a new turbo at some stage.....the most kms I have seen on a well serviced car is 155kms before the turbo went and the guy drove the car very nicely most of the time!... He had the banjo drilled out and a dump pipe!

I think the trouble is, most of the KM's are dubious at best so it's hard to know if the turbo was done in Japan at 100k KM's and then had a cluster transplant before coming to Australia.

Ours is nudging 150,000km's and still going fine (touch wood) but I'm also of the belief that it's got more km's on it than the ODO reading.

Despite that, there's still money in the kitty for a new turbo when it gives up the ghost! (high flow of course)yes.gif

    • That idea has crossed my mind, I do a 5km walk everyday, this does take me past some bushland......I think you may be onto something 😉  That, plus 1 rock on every bin night might do the trick, it may take a year, but it could save me a couple of grand The only issue is the big 'Boonies", I have a few that weigh around 30-40kg, maybe they should be the first to go into the raised garden bed,  and then let the next owner deal with them....my daughter gets the joint when I kick the bucket, mums the word mate......LOL Noice......
    • Wow. Did you call the car a Nissan Skyline?
    • You're retired Mark, on bin night, go for a walk, kind of like you're doing the beep test. Put one rock in the first neighbours, come back, get another rock, go to the second neighbours, repeat over many weeks. All rocks eventually gone...
    • No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT
