hey everyone,,

i've seen an apexi intercooler for sale,, its meant to be for a r33 gtst,, and i don't know if it'll fit an r34 gtt,, either way,, it designed so that the piping runs behind the cooler as apposed to say the blitz one that has the piping running under the cooler.

anyways,, i have done a sketch of what the cooler looks like,,, and was wondering if anyone here has this sort of setup,, i.e,, the piping running behind the cooler.

from what i can see, it'll mean that the cooler will be way in front of the radiator and may have to be slanted to allow the piping to fit.

if any of you do have a setup like the one i mentioned,, can you please post up some pics,,

anyone see any "performance/cooling" disadvantages of running the piping beind the cooler rather than underneath???

thanks for all you help ,,

The HKS one is like that.

Works fine for me.

You might want to have the pipe that goes along the back made a bit smaller in diameter so that you dont' have to remove so much of your front bar.

I've got pics here of my install.......

the apexi one is a little diff to that,, the pipe will end up coming right across the air-con fan (will go at an angle from top to bottom),, urs goes just under the fan right? ,,

hey how much did u end up spending on ur cooler?

i've seen only the cooler for sale,, but will have do buy/make up my own piping,,,

can u also give me the dimensions of ur hks cooler please...

did u have to cut/modify ur front bar support to fit the cooler??

thanks heaps dude,,

Afro.

The APEXI kit is no longer in production. I tried for a long time to get one for the R34 but to no avail.

The radiator suppot does get ground a little, and I had to get the front bar cut a bit.

The HKS kit is 600 (800 overall) x 400 x 63 or 70.

I didn't fit it myself so I'm not sure on the ins and outs but I'm happy with it.

Like I said though, if you are making up the pieps yourself, then make the pipe that goes behind smaller than 3" (the HKS is 3") so that the cooler cna sit back much further which would mean less cutting of the front bar.

If anyone ever hits my front bar and I need a new one (touch wood that it doesn't happen) I will make up a new pipe.

i was thinking of using 2.5" piping all around,, coz doesn't the engine bay use all 2.5" piping up till the intake manifold? The apexi cooler has 2.5" outlets i think.

or should i use 3" piping from the cooler up till the engine bay?

Do a search on Sydneykid posts about Intercoolers.

Basically, the small the diameter the less lag.

I would say no larger than the smallest bottle neck, as there's no point in having 4 inch piping, if the air has to go through a 2 inch pipe as some stage.

I think most of the R33 ones go through the engine bay, but the R34's all go through the standard pipes.

I think it's mainly to do with the standard Traction control throttle body that means it would be very hard to hand them go accross the top of the engine because of the sharp bend required at the end near the throttle body.

But I may be wrong. It's happened before you know.

RedLineGTR: The HKS cooler that Bass has is the normal spec S (?) kit for the R34, I have previously had the cooler kit fitted on the R34 and like Bass mentioned a bit of cutting is involved in installing the cooler. Oh the kit was purchased locally, if I recall correctly. :rofl:

AFRO: I've seen the apexi cooler you mentioned tho not on a car, pretty sure you will have some problem with the left hand rear out section as you will block part of the air flow to the back of the intercooler. Would be better if you can "rotate" the rear out to more towards the bottom or facing the out to the left. By means of rotate would mean cutting and rewelding is involved? (I'm not sure on how best to approach this, but someone here is bound to be better than me to answer the "rotate" question). :rofl:

ya,, the dimensions of the core is 600 X 280 X 80

that means the front of the cooler will need to be atleast 150mm (80 + 65mm pipe) from the air/con fan if the cooler piping is to clear..

i don't think the rotate thing would be a good idea, don't wanna spend any money modifying it if i buy it,, ya i can sorta see how the piping "could" restrict some of the air flow from the cooler,

but i dont think it would be a major disadvantage ( i hope)

man i can't seem to find any info on this sort of cooler piping,, well mr google hasen't been very helpfull yet , :confused:

hoping someone out there has some pics or comments about this cooler,,,

thanks

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      R33 GTR running -9 with no tune

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
