I've Met Another Crazy Kohki KR4 Owner

Recently, a fellow R33 GT-R owner messaged me on this blog about how he had successfully used a BNR34 part on his car. Murray (Follow him on IG: kaizen.r33) currently lives in Okinawa, Japan, so when I found myself there for a couple weeks of special work, it was natural that we would meet up in person just so I could check out his car (his daily!).

Beautiful! Love the quasi 400R look, reminds me of my car. And the Nismo intercooler
venting is awesome!

Once we met up, of course I had to check out in person what he had tried to explain to me via email and photos about his mod using the BNR34 rear strut tower board, which being two layered (vice the single layer BCNR33 piece) provides more rigidity to the rear of the car.


So I could tell immediately that this looked different from the usual 33 part.  First, the Nismo Performance Damper appears (and is) shorter, but that is because its mounting points are different - you can see in the next photo (kindly provided by Murray) that compares the 33 and 34 rear boards - the 33 is one piece so the rear strut bar (and thus the Nismo Damper) connects on top, while the mounting for the 34 strut bar (and thus Nismo Damper) is a separate piece that lies on top of and bolted underneath the rear board.  Murray told me that because of the different lengths he had to buy a new Nismo Damper for the rear. Because Nismo only sells in front/rear pairs, he sold his new 34 front one on Yahoo Auctions.  


Additionally, Murray informed me that, compared to the 33 board, the 34 board has 4 extra recessed holes, probably M10x50mm in the standard 1.25 pitch. He says the Series 3/Kohki cars already have these holes drilled at the factory so he had no problems adding and tightening these extra bolts down. Otherwise, as I reported in the GT-R magazine article post, this part is a direct easy fit requiring no mods to either the car or the 34 board.

Murray reports he could immediately feel the difference - an increase in rear stability - and this makes sense as the 33 is longer than the 34 and thus I would suspect that an increase in rigidity here in this area would do wonders in how the car feels.  Certainly makes sense given how this 33 was used as the basis for improvements that would end up in the 34. Incidentally, I forgot to take photos, but Murray also has the S15 trunk bar installed as well, so the improvement I think might be noticeable in my car as well.

I am very, very tempted to do this mod! I will have to research the Damper issue- whether the change in structure is effective, etc. Ideally I want not to have to buy a new Nismo Damper...

But of course I had to check out the rest of the car.  I had already noticed that this car was running those beautiful Nismo semi-gloss LMGT4 wheels, and I could already spot some brake mods.

And yes we agreed on tire choice too - PS4S

These are ACRE Dustless-Real pads and Dixcel FS 6 slot rotors. He has the 400R fender flares but told me that Nismo no longer offered the ones for the front. I will have to look into this, but meanwhile we discussed how the Nismo R35 brake package does wonders for the braking ability of the car.  I think if Murray ever takes his car to Fuji Speedway, he will realize that the OEM brakes are the weak point of the car. I did advise him to stay away from adaptor brackets made elsewhere, unless he can overcome the shortcomings I found with the set I sourced from the UK. 

While still at the rear of the car, I noticed that Murray had also installed a BNR34 rear diffuser. But it looked different than mine. And it's not just the 400R rear bumper.

I forgot to ask if the red taping is reflective. If so, nice touch!

Turns out that Murray had the rear diffuser custom-made by CW-collective.  No photos from me as my knees were not cooperating that day (but check out Murray's IG), but I did notice how clean the exhaust cut-out was.  Murray did remark that compared to the OEM 34 version, he did not have a jack up point (so he has to use the arms), but otherwise the install was very clean.  And he even used the OEM 34 plastic fins, which is a smart move because they can get damaged when backing up (although I did not see any damage to the fins on his car).

One more interesting piece in the trunk area was this old-style Nismo badge that is no longer available.  I suspect that Murray and I may have been competing on Yahoo Auctions for the last few years over the same parts...


I also spotted this side turn signal that Murray says came with the car. Yes I have advised him to get it changed out for a more inconspicuous part.


Anyway a well put together and a very clean look that works! (despite the shaved off trunk lock - done by the prior owner of the car).

And the car has a replica carbon 400R double blade rear wing

Ok so let's check what's under the hood(bonnet!).


Hard to tell at this angle, but Murray reports the new HKS GTIII-2530s work really well. I also spotted the carbon fiber Nismo Omori Factory original air intake - great minds think alike?  Also hard to tell at this angle is the deletion of the OEM CAS for a more modern trigger kit, with the engine now controlled by a Haltech Elite 2500.  And yes that is a MASSIVE front strut tower bar! 

I also noted that he was running a non-standard front lip. Murray reminded me that this was also a Nismo piece, I guess my focus has been on other Nismo parts as it didn't register with me when he told me!
A better view of that massive Midori Seibi tower bar

From what else I can recall, Murray told me that he had gotten his Xenons redone with a much brighter bulb set-up, retrofitted with G5-BRT projectors from Lightwerkz Global. Additionally, he told me he is running a very interesting cam set-up - 290 on both intake and exhaust with 10.8mm clearance.  Sounds awesome, but he admits that the decrease in engine pressure was causing him some brake pressure issues; hopefully the Auto Select Large Capacity Brake Master Cylinder he is getting installed soon will mitigate the issue.

But wait - what about the interior? Hold on as this was, to me, the highlight of the tour.

First, I noticed the real carbon treatment on the dash surround. Not my taste as I like matte and not gloss but it worked well here actually. Then I noticed the Garage Yoshida sourced HVAC relocation kit, and the 2DIN screen.  Yep, been there, done that, except of course not Garage Yoshida. 

But of course, I then saw that the instrument cluster is the old Nismo option that has the center screen. Murray told me he sadly does not have the Epson EJ1 computer module that came with it - he is on the hunt for it. 

I would argue however that he does NOT need it. Yeah I know not OEM, but his current execution is WAY better:

And if that wasn't impressive enough, once past the welcome screen:

Here is a close up:


Murray says he was inspired by the R35's graphics when he configured this set up! I am very, very impressed with this!

I really think this is way better than the original:

I mean if you are going to Resto-mod... let's make it modern, right!?

But this wasn't his only interior mod. Check out his camera mount.

We were joking that maybe this gave some more body rigidity as well. Looking forward to whatever video Murray takes from this!

Lastly - and this is something new for me - as I learned something - is this OEM R33 cup holder.
No OEM foglights yet, but Murray is on the hunt for a set!

Ok here is a better shot of the cupholder, without the carbon fiber insert:


So it turns out that the R33 GTST had these cupholders.  Unfortunately for the GT-R, the G-sensor needed for the ATTESA system that is mounted underneath this space prevents this part from fitting, but if you have already replaced the old analog G-sensor for a digital one from Do-Luck or Midori Seibi, then this mod is possible.

So this is another Murray mod that I may have to try out! Not that I EVER drink or eat in my car, but maybe if I get this part I will allow a water bottle in the car... lol.

Anyway, my thanks to Murray for taking time out of his day to swing by and let me check out his car.  I'll close this post with a fantastic photo he took... and I do hope we will be able to meet up again soon!

Next Steps at NISMO Omori Factory

So as I hinted in my previous post, Nismo Omori Factory technicians have now begun focusing their attention to the outside of the car - among other things, the wheels and tires!

And that's why the car has been on "borrowed" wheels and tires for the last few weeks. Although I have to admit, those NISMO LMGT4s look VERY nice on the car...
So I wonder what suspension the car was on while the Ohlins were being serviced...
The Ohlins DFVs, from what I understand, were removed from the car almost immediately after I dropped it off, and sent to Labo Carrozzeria to be rebuilt with the same specs as before.  A few years ago they let me tour their factory and I did a blog post to show how they do a rebuild!

So the coilovers came back quickly, in about a week... what took time were the TE37 wheels that were being refinished, fixing up some minor curb rash and the usual scrapes that come when you actually drive your car.

Damn. Gorgeous! And yes, a glass coating has been applied - both outside AND inside...
You may also have spotted the odd looking/colored valve stem. That's because they are a non-Nissan/Nismo part that Nismo Omori Factory actually agree to install - an aftermarket Tire Pressure Monitoring System (TPMS).   In fact they had an aftermarket one (made by Orange Electronic) designated a "sports model" (to allow for high inner tire temperatures) in a box when I visited, and were even kind enough to open it up for me to show me how it worked.  Unfortunately the screen display was a bit large and I've already got enough stuff (Blitz exhaust valve, Do-Luck DTM-2, ETC card reader, boost controller, heads up display controls) in the car already so I wanted something stealth.

So a few internet searches later I stumbled on this - a TPMS where the display is an app you download to your smart phone (either iPhone or Android).  I've actually already used an aftermarket one on my Lexus, but this displayed its output on a small screen that had to be installed in a blank switch location.



Of course, I have no idea if these work yet. Of course once I test them out, I will post the results! Fingers crossed...

Back to the wheels and tires... I was surprised when Ochiai-san sent me the following photo.  I had always thought that Nismo Omori Factory had tire changing equipment on premises, but for whatever reason they outsource to this guy who arrives with all of his equipment on a truck!

Look closely and you can see my name on the tire...
I know mobile tire fitters aren't a new thing (and in fact I need to find one to do the tires on my Lexus...) but I wonder how Nismo does the tires on their racing cars? And yeah, I ended up going with the Michelins, the price was TOO GOOD to pass up...

And talk about attention to detail! Or maybe they know me a bit too well...
Yep, blackened wheel weights so they don't stand out.
Oh and yes that missing ashtray? A long time ago I think I broke it like this when I tried to drill a hole in the back... I was experimenting with LED lighting of the ashtray and tried to get it to light up via the LED I had attached to the cigarette lighter ring. This was during my pre-Dremel days.  Buy the right tools, people!!


But guess what - new stock still exists for this part! So a new pristine one on the way! Cannot wait to get back into a car with an "OEM" look dash!

So what next? There is one more item I asked them to take care of but I haven't received any photos or messages on that yet. I'm also curious about whether we can get an alarm shop out to Nismo to help remove that crap alarm.  I'll keep you all posted of course...

Picked Up the Car Today from NISMO! (Part 2)

Morita-san asking me to inspect the car before driving home. Photo by Ale.  Thanks! 
So driving impressions on the work that was done - as mentioned in the last post, I guess you can say it's very "OEM."  The car now feels like it was designed to drive the way it does from the ground up, with everything (power, response, ride, handling, braking) in perfect balance.

Before the Nismo Omori Factory Chassis Refresh, the car would at first literally take about 5 minutes to warm up "its legs" - like an aging athlete, and even then the car felt somewhat twitchy. Powerful and fun, but somehow not polished? Which I attributed to the 10 year old tires the car is (still) on...  I now think the rubber bushes had degraded more than I realized.  And I bet the new rear suspension member bushings make a difference too. Various guest drivers had previously commented on how well the car was balanced, but I think it's now at a higher level altogether - as if purposely designed by Nissan this way, and not simply happened to be put together well by chance (by me).

Today, the moment I got in my car, everything felt a bit smoother, lighter and yet still super communicative, and it seemed very balanced with the smooth power of the Mine's engine.  So the car basically rides smoother, and is likely a bit less tiring to drive.  Remember the car is running on smallish turbos, so the boost comes on low, and then builds and builds and builds... meanwhile shifting the 6 speed Getrag with the shorter gears, so the engine remains on boost... and then we end up going too fast, so use those massive R35 Brembos which calmly scrub off speed.

So I'm wondering - can this be improved? Remember NISMO removed the Do-Luck Floor Support Bars, and with the new rear suspension member I'm sure the Spoon Sports Rigid Collars are gone too.  Also the last time I had the Ohlins DFVs rebuilt was about 4 years ago.  So I wonder if the coilovers are operating at 100%? And yes, still on those old tires, which means I'm sliding in some aggressive corners... that reminds me, I didn't even notice the ATTESA kick in when I did so, which means it did so progressively and smoothly... like it's supposed to!

Photo by Mr. Ale
Anyway, I was having so much fun driving home, I wanted to keep going except of course, I needed to get the car into its new garage space.

So here it is. What do you all think? (ignore the boxes - containing new LMGT4s actually...lol... and the original side skirts wrapped in plastic... I need to hurry up and finish my garage project ASAP...)
Somehow the camera didn't quite catch accurate colors...although yes should probably replace the LED bulbs with something a bit more blue...



Finally! Both cars in the new garage. Along with Ale's Z parked out front in the driveway.
I noticed it too. The front end seems to be elevated a bit.
In taking these photos, you notice things -  I'm pretty sure my car never had so much lip clearance before. Which I think comes from the DFV coil-overs, which seem to have been adjusted a bit too high by NISMO...just for aesthetic purposes I'm going to have to lower the front a few centimeters. The gap between the front wheel and fender is huge!
Right? The gap seems much less here - back in 2015...
Actually in order to find the above photo, I found this blog entry where Ohlins recommends a distance of 350mm between wheel center and the fender (which results in a lowered stance like above). So something for me to do next weekend...although now that I think about it, lowering it too much resulted in rubbing the inside of the fenders. Will have to experiment.

And finally, check out the new GT shiftknob. No more scratched up BNR34 unit to remind me of you know who everytime I shifted.
Still cannot believe how beautiful that red stitching on the leather is...
Anyway, I know that I need new tires, but before that, what should I do? Detail it myself? Or try to begin fixing the interior? Hmm...and now with the new garage, there is so much more I can do! Stay tuned!

Skyline Festival, Mine's, Nismo and Nissan in One Day! (Part 2)

So as I mentioned in Part 1, after checking out some cars at the Skyline Festival, we decided to drive to the tuner which blessed my car with a handbuilt RB26DETT, Mine's.  

Not surprisingly, upon arrival we found a customer's white R33 GTR in the parking lot:
Note interesting vented front bumper!
Very clean
Speaking of clean I was parked next to a very clean 34...
I didn't like those wheels too much though...too much hassle to keep clean
This photo got me thinking... do I need to darken the red lens of my diffuser LED?
Obviously for Kunal, this was tuner heaven, and they were even kind enough to show him around (the garage, the engine assembly room, etc.) while Thomas and I asked a bunch of technical questions as well as inquiring into some future products... lol. (something to look forward to on this blog!)
Kunal with Nakayama-san, Chief Mechanic
(and yes the Takumi who built the engine in my car!) at Mine's.
The man has built over 1000 RB26 engines during his career...!!!
 The boys memorialized their visit with this photo:
Thomas trying to act cool, Kunal WAS cool...
And then we were off to our next stop...

The new NISMO Omori Factory, no longer in Omori Tokyo but in Tsuzuki-ku, Yokohama (access map here). Inside, we saw there were several cars displayed, including the original Z-Tune, but also noticed actual cars being worked on behind the glass:
Like this Clubman Sports BNR34

There was also a 400R, but it was slightly out of camera range, darn (and we were not allowed inside).

Of course there was the gift/parts/accessories store selling all sorts of interesting goodies:
Not enough time, not enough money...
But I really enjoyed the nice touches on stuff like:
A NISMO vending machine!
Camshafts being used as door handles to the bathrooms!
And more camshafts in the bathroom!
As we were leaving, we took one more photo outside... I didn't want to do this but the guys insisted, so:
Backing the car in as if it's being driven off the showroom floor!
It was getting late, so then we headed over to nearby Nissan Global HQ in Yokohama to check out what cars were on display as well as do some more shopping at the Nissan Gallery Boutique store.
Kunal found a cool T-shirt...
Nice clock, but why the black caliper? Need gold!
And of course, the $5000 carbon fiber GT-R suitcase...
And check out what we found on the Nissan Gallery floor:
Trunk of an R35 GT-R. And herein lies a clue to a future mod for my car...
We then headed to a nearby restaurant to discuss all things cars while eating all sorts of Japanese food, a good way to finish a LONG, but good day! Thanks to Kunal for understanding my obsession to keep my car clean and parked securely (and for patiently tagging along with me lol), as well as for letting me share some of COE's pictures on this blog!
