G E T R I D O F T H E G K T E C H F A N :yes:

I had heat issues for the first time ever after replacing the fan from stock to GKTECH, changed them back last weekend and test at SMSP and temps are back to perfect!

Drove the car on saturday when it was pissing down rain, maybe 12deg outsde crusing at 60km/h in 4th gear doing 2000 revs. Temps reached 120deg.

> Put standard fan back on (not even a good quality one, i cut about 1/3 of each blade away so it didn't foul on intercooler piping)

> New coolant

> Bleed system

> Has not gone over 80deg so far

Seems like Matt may be correct.

Awesome! Its the only change on my car and its sorted! :yes:

maybe the gktech fan is turning in the wrong direction or has the blades mixed up. so instead of pulling in air thru the radiator.. its pushing it.

This was my first thought too, but all checked out OK, fan was just rubbish!

bottom line, it's just shit lol

same thing on my mate's S15, OEM fan cools better.. the GK Tech one just makes loads of noise and that's it

Don't know whats going with you guys gktech fans but mine worked great since ive chucked it on noticed 2-3degrees improvement and Ive tested mine in mid 30 degree days on the track.

There is quite a few of us that have had issues... Post a pic of your setup for comparison?

The blades on the OEM fan are way bigger and work so much better... They are closer to the radiator too!

LOL then it has to be really utter crap :rofl2:

how bout other electric fans? the Billion one seems fine... or there's an american brand as well.... cant rem the name

i was using a japanese branded fan on my S13.. temps were exactly how i wanted them every time.

The old engine fan does a hell of a job! No need for thermos etc...

actually once the engine is warmed up, there isnt a need for a thermostat when u are on the track. in case it might impede the flow plus... if the thermostat jammed... u'd have a problem. happened to me before..

Thermo = Electric fan... See above post :P

Negative, the fan was on the correct way 110% sure.

Heres a photo of my bay as you can see no special ducting or anything just std shroud with the koyo rad and lol half of whatevers left of the plastic undertray. Weird why some setups works some doesnt.post-50426-0-52675600-1393827135_thumb.jpg

OP what car do you have I was also at matsuri last weekend in the white 33 with bogged up rear quaters.

I have had the same troubles with over heating, after a good flogging of the car would get pretty hot, hotter than it usually has, investigated more and found a coolant leak, fixed that, tested again, same thing was happeing again, found another coolant leak, finally fixed the last coolant leak, took the car for a drive and it still is getting hot after like 5 minutes of skidding, the only thing I can out it down to is the standard fan, I had to chop about 2 inches off it to clear the cooler pipe, still had stock shroud and aftermarket radiator. Just brought some thermos gonna install them on the weekend and see how that goes with the temps, I'm hoping that this fixes the overheating issues!

I wouldnt blame the fan for that... I would start by going back to basics! Make sure all leaks are fixed and then start working on things like the radiator... Is it blocked, is it getting airflow etc... Waterpump... Is it flowing, is it worn etc... Headgasket... is it pressurizing the cooling system and causing your leaks bla bla bla :)

I was using the GKtech fan and having issues. Swapped to my chopped out standard fan (I had to cut mine just like you did) and it has fixed all my problems.

Good to hear :yes:

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
