Hey guys,

I have done a search and nothing really has come up. I want to fit a slightly bigger cooler into my car, now I don’t want to go big aftermarket as I’m not a fan of the look. ( I am considering using a matt black spray can to help J)

I would like to get some insight if a gtr cooler will be a straight fit and how much bigger/ thicker it wil be?

I have also considered getting an r34 cooler too?

I only really want to be pushing 10-12psi through it, but not too keen on using aftermarket one. What is the easiest/ best option.

Plus I want to keep the pod, so I guess a stock cooler would make it leagal :D

Btw its an r33t.

Thanks

Pretty sure the R33 and R34 coolers can handle it. I think people just upgrade due to the lower cooling efficency at that boost level. R34 cooler should be alright for 12psi through a stock turbo

I used a R34 SMIC on my R33 and noticed the difference straight away. Was a direct swap which was very easy to do, plus didn’t have to cut anything off the car. Seemed to rev out a lot easier and was more responsive. If you don’t want a FMIC and only aiming to do the usual mods with 10psi or 12psi, then the R34 SMIC is perfect.

Although Im running a FMIC on my R33 now and it feels even better. Kind of feels like more torque. I was very happy! :D

Running an R34 SMIC will work - However, once the power bug hits you, it will hit hard - and then you will regret not getting a fmic in the first place.

I believe the GTR coolers are more pricey then a aftermarket fmic kit.

The issue with those smic's is heat soak, and LOTS and LOTS of it.

If you can get an R34 smic for dirt cheap(40-50) then sounds ok, otherwise save the money and get a fmic and just paint it black.

r34 SMIC is a straight fit so its a piece of piss to do. Good for 200KW ATW but constant runs see a drop in power. Heatsoak. I havent installed a FMIC for the same reason. That and id rather not hack the shit out of my car to make it fit...

r34 smic on a r33 will handle 200rwkw easy...

but if you want something a little better and still stealthy, get yourself a r34 ARC SMIC..

harder to find, but worth it,,, they flow nearly as a front mount does without the heatsoak or the r34 smic...

or at least that has been the experience with the ARC cooler on my 33...

guys can u explain heatsoak concept i'm not gonna pretend that i understand it. I'm not gonna boost it past 10-12 aka 200 rwkw. So i think that an r34 cooler would be alright?

a) don't wanna cut up all the crap cause makes the car look mega cheap

b) the cooler look doesn't float my boat- Considering getting and aftermarket one and spraying it matt black.

But i reckon that a nissan cooler should be good, like some of the aftermarket crap floating around is pretty bad. The other think i was gonna ask, how does the stock ecu handle 10psi cause i took my blow off value (lol yer i don't like the cooler look haha) cause it was backfiring, skylines are just tuned really good stock i concluded plus the stututututu was too much attention lol

Heat soak occurs when the intercooler can't shed the heat that it removes from the compressed air of the turbo. On a hot day, the intercooler can, like a sponge, become "soaked" with heat and lose its effectiveness.

Heat soak is one of the major reasons that turbocharged cars tend to run slower when the weather is warm.

Common solutions to improve heat soak is the use of a higher-capacity intercooler, or one that's mounted more in-line with the air flow, as in front-mount intercoolers.

if it is only for street use and you don't drive that hard the r34 cooler will do the job. if you plan on going to track days at all then don't bother with the r34 cooler. it will suffer from heat soak extemely quickly which results in more chance of pinging and less power.

As the OP was last heard of in May one presumes he has already made a choice but for the record I have read all three of the above links and I am still not convinced that the R34 smic is not a good choice for someone with a stock turbo. If you do repeated runs on a dyno with none of the fan air directed through the side vent then I am sure that the SMIC will get hot but I have used a trust smic on the track (around 200awkw) and when I pull in the inlet pipe (coming out of the intercooler) is cold. I am now running 16psi with a GCG highflow (around 220 -230awkw - will dyno again soon) and have a Nismo smic which is not much bigger than the R34 and it is now probably marginal. I am looking for an ARC smic and that will do me. I have slightly enlarged the vent and have made sure that the shroud directs all of the air that comes through the vent through the smic core. At this level and above I am sure that there will be benefits from a front mount but I don't want one. But with the standard turbo an R34 smic will definitely be adequate - you can pick them up here for $50 - $80 and there is no installation cost and no attention from the cops.

      R34 gtt rb25det neo timing belt kit

      By drifter17a · Posted

      So now doing the change and first time dealing with rb so little nervous giving engine power and potential for screwing it up When you align all marks and then remove crank bolt, timing move little I assume you can put the bolt back in once you have removed the pully to get timing to where you want?   here is pic of my both intake and exchust cam aligned, depending on angle you look they seem to be either aligned or a half tooth or so out. Any thoughts? Should you angle your face and look at each mark that way as if looking straight rather than from above as it can be misleading   <a href="https://ibb.co/ZpnhcvbF"><img src="https://i.ibb.co/HfWrGR9b/IMG-4447.jpg" alt="IMG-4447" border="0"></a> <a href="https://ibb.co/4wm2wn4q"><img src="https://i.ibb.co/JWBqWwr1/IMG-4445.jpg" alt="IMG-4445" border="0"></a>   https://ibb.co/ZpnhcvbF https://ibb.co/4wm2wn4q

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Unpeeling the Orange

      By sunsetR33 · Posted

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

      By Kapr · Posted

      Ok so no 4cyl clutch... Yeah it is a factory manual. So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?   EDIT: https://www.ebay.com/itm/224291042776 Is this ok?   EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap) It will be there for a little while. Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.
