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...
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).
