Vq25 Dump Pipe

[sky^rkt]

hi guys just wondering what are my options for a dump pipe change on my m35 also with the exhaust obviously wanting to go bigger

[bigkevracer]

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.

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

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

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.

Thanks for the replies. PM incoming...

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

[slippylotion]

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.

[scotty nm35]

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.

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!

[slippylotion]

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.

Yep; no design fault there...

[slippylotion]

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)
