hehe would push the intercooler into the engine.... its real tight in a skyline enginebay as it is. with an SR conversion it'd be awesome, but I don't see many advantages in a skyline engine bay with an RB. real estate front to back is real tight in one of those. Didn't really think about the heat rising from the radiator...

Ive been a fan of the open V mount... ie radiator vertical behind the intercooler which is on an angle with a bonnet vent... but the V mount on the R31 is interesting... for race use only I guess.

If you wanted to be a real tricky dicky you'd make the whole thing out of flexible piping and mount some servo's to move the radiator and Intercooler from vertical to V mount according tot he speed you were goin at... :D hmmm now there's an idea...

LoL all the gain you got from the shoter pipes etc, you would lose in tricky electronic gear :P

what if you leave the radiator as is and mount the ic on top of the engine(possibly a sm but thicker radiator to compensate that way the fans can still suck air through the radiator and pull air through the intercoller, best of both worlds?

Like a subaru?

Yep, but the hot air comes up from the radiator and goes through the intercooler and out the bonnet (ie; hot air rises) On its way though the hot air heats up the intercooler.  That never happens with a FMIC, the radiator is behind the intercooler and the engine or electric fan sucks the hot air from the radiator, away from the intercooler.

In a > mount in traffic or stationary, the intercooler will quickly get to 90 degrees, which is the temperature of the air coming out of the radiator.  It will cool down once you get moving, that why it is an OK setup in a race car.  But a waste of time and money in a road car.

Oh and you should see the damage if you have a slight front end tap, makes a real effenn mess. :D

but at idle the turbo is not running any boost. so it wouldnt really matter would it? as soon as you start moving the superior air flow would cool it down pretty quickly. wouldnt it?

Ahh no, the intercooler is still hot, so it heats up the air going through it. Until it cools down, maybe 2 to 10 seconds depending on speed and ambient air temp. :D

This is what i'll be running in the lancer project im working on ATM, however the is no reason that the intake itself cannot be partitioned right from the intake itself, running a thermo fan on both the radiator and the intercooler! separate intake ans thermo's fresh air at any speed to both cooling devices!

OH and whats wrong with running the radiator at the top to stop further heat soak????

i will be keeping an eye on this thread for sure!

GTR-NUTTER - that would defeat the purpose.. they want separate intakes for both devices, so a conventional IC with horizontal radiator would still be heated by the IC before the rad!

I guess because that kills the idea of having shorter piping???

Which brings me to my next question, does taking out that little amount of piping have that much effect???

that could be true, but it would depend on what engine the car was using! if say it was a front facing plenum then the IC on top wouldn't really affect the pipe length compared to below....

however a standard rb25 inlet manifold would best be used with the IC on top, this i pressume wouldn't be the case if going to the length of ">" mounting these coolers!

better response from throttle on/off, and minimal chance of heat soaking the pipes (not an issue really within the pipes only IC core)

But if you have the money to throw around on > mounting stuff, then you probably have the money for better forward facing plenums, and internals, and turbos, etc etc :mad: Either that or WAYYYY tooo much time on your hands.

      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.
