Hey guys,

Recently my clucth fan died in the skyline and rather then getting a replacement i decided to get thermo fans and a new alloy radiator.

Your up to speed so NOW!

I have done everything i needed to including swapping the thermostat while i was in there, BUT the radiator i have has not got the 2 oil leads on the bottom like the OEM had. What can i do about this? do i need to buy another radiator? because most performance alloys i find dont have the 2 oil holes at the bottom?

Any help would be great guys!

After researching i have discovered its because this radiator is for R33's (Even though everywhere even blitz market them for both?) and they do not have the oil cooling, i think its for heater? anyway I guess the question is has anybody fitted an R33 radiator to an R34? if so how did you by pass the problem?? If i find any more information i will continue to post for people to help them.

So I take it your car is auto? Normally the auto trans cooler runs through the radiator to change this around is quite simply ad another oil cooler you can get these cheap and small to place in pretty much any location that gets airflow.

I have used the expensive kits that also have a fan built onto them as standard and would have to say that I completely wasted my money, I ran a cheap one from another company and got better results. Just make sure you mount it somewhere with good airflow. I use to mount them behind the front wheel on the floor of my drag cars but I didn't have speed humps to contend with.

If you have the standard front bar try mounting it on the drivers side under the head light, you will also need to make a few slots in the plastic inner wheel arch so it will be like the passengers side where the inter cooler is mounted if yours is turbo.

From memory the oil lines run up the drivers side of the engine bay, I would try to keep them as short as possible. If you really want to put them on passenger side run some addition hose along the radiator support and back, make sure you use a good hose and the cheap one will flex and perish prematurely causing a major failure for the transmission.

I have bought heaps of stuff from sydney speed supplies when I was living interstate and got it delivered the next day. They do a cooler kit at a very good price and they also have a few different styles I would try giving them a call tomorrow.

thanks for all the replies I have done everything and ended up picking up an oil cooler kit and attached it where you said in front of right side bumer air vent. everything was running fine and driving around in 60 zones ect was no problem but once i hit the high way my engine temp got really high and only after 2 or 3 mins of driving. Im using two 12" thermo fans in a shroud anfd i guess thats not good enough. I was thinking it could be because it was just bought of ebay mainly for the shroud and the fans could be very shit and i need a better quality fan. Or maybe i need to run a bigger fan on the side where the input/output coolant flows, maybe a 16" instead though if i do this i will be wasting the shroud and i havn't seend 16" shrouds for sale .

Fans are only helpful when you're still. At highway speeds, the air flowing through the radiator should keep your car at normal temperature. Either you have a very shit radiator, or you have another problem somewhere (possibly a faulty thermostat).

exactlly what i was thinking. I replaced the thermostat when i was doing the swap though the one the mechanic gave me was shorter in length but same width, was a tridon TT268-180? has opening temp of 82 degrees... so i dont think it is that? could be a shitty radiator? dont think so but posible ill do another flush and check over everything and see what i can find. I have to admit though the car does sound 10 times better then with the clutch fan, slight increase in throtle response and i found when the fans kick in it doesnt drop under 800 rpm at idle. alot of people where saying there car almost stalls when it kicks in to them people i say maybe you need to wire them better or something?

do you mean like opening the top bolts when refilling, on the air intake manifoldor/ plenum what ever you want to call it? I did that. I also bled the system the same way i usually do? never had problems before? well im going to bleed and refill and check for leeks then im going to take it out tonight for a big run. see how it goes :)

      Hello, Newbie, anyone know my 32's history?

      By Leigh_Mack · Posted

      Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!

      2020 Nissan Skyline 400R V37/Infiniti Q50 RS insurance in NSW

      By sonicii · Posted

      As far as I know, Infiniti stopped importing vehicles before 2020, even though they were still selling their stock for at least a year or 2 after that, they were older build years, therefore, you can import a 2020 400R, because you couldn't buy an AuDM 2020 built Q50 RS. As for insurance, you might need to go through one of the enthusiast insurance companies, they tend to insure a lot more grey import models than the mainstream insurers as Duncan mentioned.

      Question about R34 GTT A/T Solenoids

      By DraftySquash · Posted

      So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By Kinkstaah · Posted

      Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.
