Nissan Frontier/Navara 05 Turbo Rebuild DIY

Hi reader,

It's been a long time since I update anything in this blog. Today I'm going to post on how to remove and rebuild/repair your frontier/navara turbo. This applied to only D22 YD25DDTI Engine.

Turbo info:
Maker: IHI
Model: RHF4 VN3

First, you must buy the turbo rebuild kit for to continue.

Second, start by removing the intercooler from the engine. Then remove the aluminium casing that cover the exhaust side . Crawl under the vehicle and remove three bolt that tie the exhaust to the bullet. Unbolt the 17mm bolt that hold the turbo oil intake. Unbolt the 14mm bolt that hold the exhaust to the engine. Move the turbo drain hose away. Now you can happily unbolt the three 14mm bolt that hold the turbo housing from the exhaust and lift the turbo from the vehicle.

Third, remove the aluminum casing that cover the turbo. Then remove the clip that hold the wastegate to the exhaust. Then remove the V-Band Clamp that hold the turbo to the housing. A flat screwdriver and a hammer should help you to remove it from the housing. Now you will see the exhaust turbine side. Check if it has any damage. If yes, then you will need a new turbine that comes with the shaft.

Now, you can remove the 17mm bolt that hold the turbo oil intake, two 10mm bolt hold the turbo oil drain and four 12mm bold that hold both the pipe from the airfilter and to the intercooler.

Fourth, remove the wastegate from the turbo. Then remove the 5 allen key screw that hold the housing. Remove the housing to gain access to the compressor turbine. Check compressor turbine for any sign of damage. Check the housing if there is any sign of the turbine grinding the housing. Check turbine play. Mark the turbine and top of the shaft with any marker (I use white correction marker for this). This is for easy assemble and keep the turbine balance (or you can have it balanced at turbo specialist shop).

Fifth, remove the four allen key screw. You'll will gain access to the oilseal. Remove the three allen key screw that hold the brass plate. The journal bearing is under the brass plate at the compressor side. Pull the exhaust side turbine + shaft. You will see a locking mechanism that holds the bearing. Remove it carefully with small flat screw driver. Now you can replace the bearing. The oilseal for the exhaust side is on the shaft.

You will want to put an engine oil to the parts before reassemble it back. Notice that the housing is glued with a Red silicon. You may want to put new silicon on there.

Testing your turbo :-
Make sure you fill up the turbo with engine oil before test. Do this before putting back the snail casing.

~> Blow the exhaust side turbine with compressed air (I use air compressor). You will hear a wind siren-alike sound.
~> Check for the shaft play. You will see if anything wrong here. Check if the new oilseal holds the oil properly.
~> Satisfied? Then you can put the snail casing (don't forget to add silicone) back.

Well, it took me 5 days to get this all right (no leaking, no smoke). This is because the lack of knowledge about turbo. Done many studies about turbo in past few days.

Good luck on your DIY. ^^

Below are some pictures ^^

EGR Blank ~ Nissan Frontier/Navara D22

Hi all,

I've done EGR Blank to Nissan Frontier yesterday and the result is quite nice. The noticeable change is less black smoke.

So what is EGR and why do we have it?

The EGR is simply an emissions reducing measure. When the engine heats up excessively, nitrous oxide is produced and this is one of the worst emissions. To reduce this production, the engine temperature needs to be reduced and the EGR allows recirculated exhaust gas back into the inlet side of the engine. This is a continuous process happens more when the engine temp rises and help to reduce the operating temperature.

It does however, to differing degrees, make the engine less efficient and also curbs the maximum performance.

Some EGR applications can have the mapping of the valve changed to reduce the actuation, and others simply choose to block it off.

Blocking off is not possible on a petrol engine because of the MOT checks. But this is not the case on diesels and it certainly stops the gunge creation, as long as you are aware that the engine is producing more 'naughty' gasses than it was originally intended to.

So, where is the EGR Valve located in Nissan Frontier D22?

Where should you block it?

You need to remove two 14cm screw to pull up the original gasket.

In order to remove the screw (you wrench will not fit for the screw below), you need to move the alternator.

In order to move the alternator, loosen the number 2(in picture) screw a bit. Then, loosen the number 1 screw. Remove screw number 4 & 3. Remove screw number 2. This will take off the assembly completely. Then, push the alternator to the left, take off the belt and push the alternator to further right. You will have enough room for the wrench to take off the screw.

Note: Before you loosen the alternator screw, make sure you mark the screw placement for easier to re-tight the alternator belt.

Take off the original gasket(it should be easy). Put it on a thin metal plate and make a duplicate but leave the center hole alone. It should be done like this:-

Now, after you have satisfied with your fake gasket, it is time to put it back. Sandwich it together with the original gasket where the original gasket will facing front. Means, EGR Valve >> Original Gasket >> False Gasket. Then, reassemble back all the parts.

BTW, this is just a DIY guide and I will not take any responsibility but I've done mine without a problem. If you had done yours, let me know..^^

Lost Planet 2 on Nvidia Geforce 7300GT

Lost Planet 2 Sequel to Lost Planet: Extreme Condition

Hi all,

If you are interested in this game, please visit http://en.wikipedia.org/wiki/Lost_Planet_2 for more info about this game.

Here, I will upload the Benchmark Result (Test A).

Ranked C (21.4FPS) on my GF7300GT

Well, at least it played well (>15FPS) on actual gameplay(640x480, all setting low). By the way, my PC specs are:-

Athlon X2 4400+
Geforce 7300GT 256mb 128bit PCI-E @ 8x
Abit NF-M2s Mobo
1.5GB RAM
Vista Ultimate 32Bit

While it played >15FPS on Test A, it perform worst in Test B when average FPS is only <5. So, it means that I have to get a better GFX to play this game ^^.

This are the spec guideline if you want to play this on your PC.

Manga Downloader ~ Mangafox, Mangapark, Mangahere, Mangareader

Reading manga online is stressful if the server lags or your internet connection is not very fast.
Because I want to read manga offline (in my HDD) and cannot wait for it to load online, I searched for a downloader and found a good one.

It is called DomDomSoft Manga downloader. It is pretty easy to use. Just install it and you are ready. Don't forget to update it as manga sites always changing their website script to avoid users downloading their manga.

Here's the screenshot: -

You will able to download it from:

Quantum Pendant anyone?

Good day or night all ^^.

Today topic would be the Quantum Pendant. What is Quantum Pendant?

Quantum Pendant is a necklace made from natural minerals that are fused and structurally bonded together at a molecular level.

So why is it so special?

It produces scalar energy that helps to enhance the body’s biofield. The Quantum Pendant promotes positive flow of energy and helps to maintain energy balance. It helps to restore energy that has become weak in the body. By restoring the energy balance in the body this pendant helps one to maintain health and well-being.

I've been using Quantum Pendant since 2009. The most noticeable affect is that I can sleep early (having sleep problem for a long time) and also it shorten up my short of breath recovery in sport.

I do some digging in the web and found other benefits of the pendant :-

• Increased energy levels
• Increased strength
• Enhanced immune function
• Improved concentration and focus
• Shorter healing time
• A deeper and more restful sleep
• And protection against the harmful effects of EMF energies.

and from scientist study, the pendant also :-

• Improves circulation
• Enhances cell permeability
• Enhances cellular nutrition and detoxification
• Promotes the unclumping of cells
• Reduces headaches and migraines
• Helps protect DNA from damage
• Improves sporting performance and physical prowess
• Reduces joint pain and arthritis
• Reduces inflammation
• And may help reduce hypertension and high blood pressure.

Those picture above are my Quantum Pendant. Notice the small break at the edge of the pendant. It means that I've already wear it for a long period. ^^v

Every Quantum Pendant has its own individual serial number and is part of a LIMITED SERIES.

How Low Can You Go with Microsoft Windows 7

Many people will ask, "Can I install and run Microsoft Windows 7 in my computer?" Well, it depends on your computer specification. Microsoft recommended this in their website:

Taken from: http://windows.microsoft.com/en-US/windows7/products/system-requirements

Actually, it require less to run this OS(Operating System). Here are some proof showing that this OS can be installed and run in lower spec computer/laptop.

1. Windows 7 - 266MHz & 64 MB RAM

The video: http://www.youtube.com/watch?v=A6KRqm9sM9c&NR=1



2. windows 7 in AMD 90 Mgz (Windows 7 in AMD 90 MHz)

Video link: http://www.youtube.com/watch?v=lqdmVOgellQ&feature=related

Totally can run but not useable since booting takes a lot of time and opening a program takes minutes.

Windows 7 consume about 12Gb of your Hard disk after install. If you want to experience Windows 7 on your old PC, get the windows 7 Lite version which only takes 2Gb of your hard disk.

So, how low can you go with Microsoft Windows 7?

I would say (according to the video) :-

90MHz with 512Mb of RAM, 266MHz with 64Mb of RAM.......
Lowest spec would be Pentium II 266MHz with 256/512 Mb of RAM?
Get your old PC back to life on Windows 7 ~ciao~
