More Work Done at Nissan Prince Fukushima!

Last time, there simply was not enough time to finish all that I wanted done.  To review, I really wanted to have the chassis refreshed, as well as protected. That, and given how I think these kinds of vehicles tend to be left outside, I figured replacement of all consumables, including the door rubber seals, would be a good idea. 

So, when I had time - this was in August before the break -  Midorikawa-san was kind enough to meet me at Nismo Omori Factory where he picked up the Elgrand on his flatbed.

Right down the street from Nismo Omori Factory!

And up up...

And done!

And as a preview of how I want the Elgrand to look, I had found some perfect "Urban Chrome" edition wheels on Yahoo Auctions (taken off a brand new car) which I prepared by applying what is supposed to be the best overall ceramic coating for wheels.

Longevity, resistsance to heat and brake dust are what I want.

Ready to go!

These wheels got loaded into the Elgrand when Midorikawa-san picked up the car.

A few days later, he reported that a closer look at the Elgrand revealed some problems they hadn't spotted before. Of course not needing the car immediately my response was - let's get it fixed up properly.

One item was the worn out and cracking bushes in the lower control arms.

New lower arm installed!

And this driveshaft also had to be replaced:

Check out that cracked boot!
Definitely not good

Also, we decided that the suspension, given how heavy the car is, was showing signs of end of life. The ride was a bit too bouncy, enough that even my kid who normally does not get car sick, did.

Naturally, that meant I would change these out for the better alternative:
Nismo S-Tunes

I think these Nismo S-Tunes look great! They lower the car 2 cm up front and 1 cm in the rear.

Hard to tell maybe?  I wonder how the ride feels?  We took this opportunity to fit Rigid Collars to the Elgrand as well.
Already has the darker wheels on...

One thing that didn't get done last time was changing out the spark plugs:


Remember the wheels I had purchased and prepared earlier? I decided that despite it being the VIP grade, that I wanted to make the car look a bit less chrome-ish. Non VIP grades of the Elgrand come in an "Urban Chrome" version which means the wheels and other chrome trim such as in the headlights and tailight cluster utilize dark chrome. Of course, this means we should try to get the emblems to match?

Midorikawa-san though proposed painting the emblems a dark bronze color. Ok, let me try this...



Then some work on the interior. 

First, the onboard cooling/heating box is secured in a way that prevents me from making mods behind the dashboard.  The box sits in front of the common center console, which also loses the drawer in the front so this box can "mate" with the center console. So I asked two of the six securing bolts to be removed so i could easily remove both in order to access behind the dashboard.

This stay and bolts secure the cooling/heating box

I asked them to leave these screws OFF - as otherwise you need to remove the seats to access them!

Second, the shop that laid the sound insulation on the floor had a go at adding USB charging ports to the rear of the center console but got it a bit wrong.
Not exactly straight. I wonder if he was drunk when he was doing this...



Looks fantastic! Thank you!

After a few weeks of waiting for the final parts to be installed - the Nismo aero kit - which first had to be painted to match this particular color - Midorikawa-san finally sent me these photos last week to let me know the Elgrand was done!



Looking fantastic, right? No more of that excessive bright chrome. Except...

Looks like someone forgot to paint the larger rear spoiler! What to do?

Anyway, two days later on Sunday when I arrived by taking the bullet train up to Fukushima, Midorikawa-san met me at the station and immediately drove me back to the dealership where he showed me what he had arranged to be done, for free.  His overnight solution was to get the local car wrap/PPF guy (the one who did my Skyline Nismo) to wrap it with this carbon weave. Came out pretty good, and the black paint underneath has some purple and silver flakes in it. Interesting....

A carbon wrap, but very well done!

And then, he walked me around the service area to show me the rest of the work they did.  First, all of these parts and boxes are for or from the Elgrand.


And here are all of the rubber moldings that had decayed and were replaced with brand new ones. Interesting some were more expensive than just plain rubber, as those that go on the sliding doors contain sensors that when activated - like when someone is not fully on board yet - stop the doors from further closing. Interesting.

And here are the bits from the original, worn out suspension.

All laid out here, inclding the interior parts that were replaced. Most of this was covered by the ridiculous extended warranty I was forced to pay for at the used car dealer, so in the end I cost them more than what they cost me. (Easily 250,000 yen of parts, when the warranty cost me 180,000 yen).

Center console bits

Door hinges. Elgrands are well known for premature wear of these parts, not surprising given those huge front doors.

The old driver's side seatbelt - it was not retracting - plus the rubbers for the rear door, also with some sensors.

Check out these deteriatoring suspension mounts. Yes, covered by that insurance.

Some other parts covered by insurance. This time the rear brake rotors - which I had found had a slight judder to them - were replaced, along with the front lower arms, which were like 120,000 yen for the pair!


It was time for a late lunch, so Midorikawa-san took me to a local place specializing in Fukushima style ramen. Check out the shape of those noodles! 
And not greasy at all!

Just in case, here is their menu.
Most expensive item on the menu is 930 yen...

Once back at the dealer, there was some time to kill as they loaded up the Elgrand, so I was offered the chance to test drive a new Nissan Note Auro Nismo!

Basically a sporty version of the Aura (more feature equipped) version of the utlitarian Note subcompact.

It has the typical Nismo aero treatment, plus a revised e-Power hybrid setup that emphasizes acceleration. This one was 4WD too! It was fun to drive and probably a good daily driver, but I dunno, after a few minutes I was kind of bored.

And another customer had brought in his naturally aspirated EN34 sedan - but with GT-R face - to get his front tires replaced.

And final stages of packing up and loading up. How to load up the left side Nismo side skirt which was not installed on the Elgrand due to its electric side step

Oh and a quick look back into the service bay and you can see my GT-R getting worked on there too. More on that on my GT-R blog.

So then I got in and prepared to depart for the long trip home...
Looks great!
Yeah I was happy just to get this car back!


On the way home, I pulled over at a Parking Area for some coffee but the line was too long so instead just decided to check out how this thing looks now from the rear.
Looks good, not so sure abou the brake/turnsignal/backup lower cluster lights though...

And when I finally got home, I was reminded once again at how big this thing is...
a few cm....

But I have to say, after a 4 hour plus trip back, I was not the least bit tired. I was fighting a cold and felt better AFTER the long drive? Amazing what a stiffened up chassis and new firmer suspension will do. Midorikawa-san had said that after fitment of the Rigid Collars, the car felt brand new - and I have to agree, it was like driving a brand new car! The stability on long sweeping curves and expressway on/off ramps was very noticeable! So this is definitely a recommended mod for this car.

So what's next? Well a few things that Prince Fukushima did not have time to do for me I ended up doing myself. Stay tuned!

Making a Quiet Ride, Quieter! Part 2 - More Sound Deadening and Improving the BOSE System?

So in Part 1, I covered my sound deadening efforts covering the Elgrand's floor, engine room, and front fenders. But I then decided to go further - not just making the car quieter, but since I was going to be opening up the front and middle doors, to try to improve how the Bose system sounds.

Starting with the driver's side door...

Taking off the inner panel revealed this weird plastic cover in the middle.

And while I was at it, I decided to swap out the stock 6x9 full range speaker


Because this Elgrand has the BOSE system, this meant this speaker was 2 ohm - thus limiting aftermarket options.  Luckily, I found a US company called PowerBass that had just what I needed!

Stock 838 grams!

Powerbass OE-693 at 1951 grams!

Of course, given the huge size of the magnet, this meant the stock speaker baffles had to be modified to fit.
So a half shield behind the speaker - I wonder if this was a cheap way to get more bass?


Test fitting, nope still need more taken off...

And thus ground away more, and then sand papered smooth

First perfectly now!

The Audio Technica sound deadening kit I bought, had these foam speaker baffles. 

It also had various foam pieces to prevent sound leakage, as well as the usual butyl based sound absorbers. These I applied around the door in what I thought would be a strategic manner.
The white stuff is 3M Thinsulate, to seal off even more areas where there could sound leakage


View of the passenger door, but without the Thinsulate installed

Close up with the foam baffle installed


the Audio-Technica Door Tuning Kit

Here are some of the butyl aluminum strips with adhesive

I installed most of this on the backside of the outer door skin to absorb outside vibrations

And then it was time to do the sliding doors. These were a nightmare to remove the inner skin, the backside which looks like this:

Same thing - 2 ohn speakers from PowerBass

753 grams for the stock speaker

940 grams for the PowerBass - not as big as a difference as the 6x9s
Oh, and with these being direct Nissan replacements, the plug snapped right in place with need for adaptors or splicing!


This Nissan kit, however, came with separate tweeters. So naturally, I figured I'd install those up front, where the OEM tweeters are.

Just snap off the grill piece - that was easy - the tough part was accessing by removing the A pillar covers

Here is how it looks underneath the grill


I measured the OEM in order to make sure the PB tweeter would fit

The PB tweeter came with these adaptors

This should fit!

And it did fit perfectly!

So the tweeter fit perfectly, but guess what - compared to the front door tweeter which immediately improved the depth of the sound - not as much of the usual BOSE "booming" effect- these tweeter did not sound good at all. Or rather, it turns out that the OEM tweeter is a full range speaker, so when real tweeters are added that have limited range, the sound stage does not feel as full, if that makes sense.

So, I went back and removed these PB tweeter and put the OEM full range small speakers back - I will have to research what to replace it with in the future!
