I was in the same situation as some of you guys a while ago, i didnt want to be cutting up parts of my car just to fit a fmic, so i decided on the Blitz LM fmic from Nengun, and i recommend it to everyone, it was so easy to fit, works great and looks awsome, here is a link to my thread i started a while ago when i was deciding what fmic to buy :laugh:

Just some thinking...but if you must have the inlet and outlet on the same side then its a much better idea to have the tanks at the top and bottom of the cooler. You still get good surface area, you can get flow through a good number of runners. You have the space to make the top and bottom tanks flow well and ide them behind the top and bottom of the front bar.

But best of all is the amount of runners you get ensures you get low pressure drop with very good cooling. After all the things are there to cool inlet chares, though some ICs seem to not be so good on that front

So are you endorsing this buy or not? I'm confused. haha

Real time results will be the important thing here. No one has tried it so im putting my hand up to give it a go. I will judge it on lag and capability to handle 300+rwhp. If it stands up to the task then ill get some pics of install ect ect .. you can then judge for yourself.

Ok recieved intercooler today. looks of good quality, welds ect. Dummy fit it to car.. ran into a problem. Now im not to sure yet what i will do to get around this. The top pipe will want to go through where the right indicator light sits. Im sure this still can be done but im going to have to have a good think about how the hell im going to get around this. Any ideas welcome ..

Have you got the cooler mounted as low as possible? or is it mounted to the front reo bar?

If you space it down so the bottom of the cooler is flush with the bottom of your front bar, will that give the clearance needed?

I am looking at one of these coolers also. Would it be possible for you to take some pics of the separator on the inlet side?

The seperator is there i looked at that as soon as i got it out of the box. I dont know if mounting it further down will give me enough clearance.. I am going to have to pull the bar off again and have a better look But i feel some cutting will be required. Unfortunately. Either that or maybe even mount it a little off center. I dont mind if i have to do that as i want to put something across the front of my bar to protect the cooler and not make it so visible to the boys in blue.

Looking at the specs it says that the Working Press. is 35-40 PSI!

So that would indicate if you are using it at 15PSI it will only flow half the quoted 400hp.

Also the temps out of the turbo can be as high as 180'c in some conditions?

Is this cooler good enough for your needs or am I being too critical or incorrect in my assesment?

I suppose a bit late now you have bought it.

Compress Air Flow Rate <600Cubic Feet/Min, Rated to 400-500 Max HP

Working Pressure: 35~40PSI

Pressure Drop 2~5psi@35psi; 0.2~0.5psi@15psi

Hot Air Temperature 32°F~302°F (0°C~150°C)

Material 100% Aluminum

What size did you end up getting? if you mount it as low as practical, and as far back, it should fit centered. There is no question of the cooling ability, the real test of this style would be a pressure drop test, look forard to results.

Well reading the specs i would have hoped they listed a test effeciency. It seems they are testing everything else. If air goes in at 150deg C, whats it come out at?

I dont understand the whole pressure drop thing. Sure its not good to have a cooler that east 3psi of boost as it means you have to work the turbo harder and my result in an increase in temp post turbo. But at the end of the day you run your boost base don what the engine is seeing. Not what the turbo is producing. (though if you have a std turbo this could easily result in you running too much boost and killing the turbo)

The main point of a good intercooler is to reduce temperautes. If the air in the intercooler is not turbulent you do not get very good cooling. Turbulence means pressure drop...so in order to work they need to have some level of pressure drop. It will be interesting to see if you rtuner think the engine can take plenty of ignition when tuning it, suggesting that the inlet temps are nice and low

it depends on what the actuator or gate gets it signal from if its at the compressor outlet or after the intercooler.

ive noticed stock r32 turbo is at the compressor outlet, so you avoid pressure drop across the core (if you have it).

the r33 has it after the intercooler so you include pressure drop. that is, the gate wont open till say 12psi in the manifold past the intercooler and after pressure drop across the core

Well.. i have the intercooler fitted to the car. I have called an exhaust shop today and they will be looking if they want to make me some custom piping tomorrow. So with anyluck... tomorrow it will be finished :|... fingers crossed. Ill let you know how it goes.

I have installed the intercooler today. Cant say it feels any laggier then the side mount with only the small amount of piping needed with this intercooler. I have a powerfc and hiflow turbo on the car.. i watch my knock level with the tune i had done with the arc in place and my knock level was starting to climb with the revs. At first i figured the cooler must be a dud and i was feeling a little pissed off.

I then knocked 4 degrees out of the timing on the Hand controller and after 4 or 5 squirts up to 100km/h through 1st and 2nd gear the knock didnt go over 9 on the hand controller. This would indicate to me that i need to get my tune touched up to suit the intercooler as the air maps are not quite right. I expected this would be the case anyway i will get the tune touched up with more boost in the next coming weeks and will post pics of install tonight.

Well i had a bit of a set back to this little project. My harmonic balancer died so the car has been off the road. I Towed the car to the mechanic and got it replaced today and Just to make sure everything was looking good before the car went on the dyno i got a comp test done aswell. Results were 170 across the board so all is well.

I rang my tuner this evening and let him know the car is back on the road and with any luck it will be tuned as soon as possible. I will let you all know how it goes.

      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.

      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.
