Bought a Koyo rad and mishimoto fans. The fans didn't fit right the first time so I send them back for another set. This time I measured the koyo rad which turns out is the issue. I had not planned on going koyo but it was suggested to me as a great product for a good price however it has fitment issues. The 2 mounts are off from eachother by 3/16s or so, to cause problems and the rad is physically taller now by over 1/4 inch. Have they changed designs or have moved to a mexican builder? Since the seller doesn't exist anymore, I'll have to remove the mishimoto name plate, do some drilling and patching (1/4 inch gap across the bottom) to install it without looking like knockoff puke. Anyone else have any issues with koyo as of late?

Mount 2

Fitment still off/round/short on the bolt.

Anyone got ideas? The supplier doesn't exist anymore (lack of staff) so I can't send the rad back. Should I:

Cut the short bracket and have someone weld an extension (most likely look like crap).

Forget the 2 top mounts and custom make 2 brackets on each side?

I pay good money but sometimes I get these kind of issues. I'm not a mechanic, welder nor do I car to spend 400 hours getting a mildly powered car on the road. Sorry if I'm grumpy. Everything is delaying.

you may have purchased a knock off product. Mine fits with no modifications and still used the original engine fan on an r32 gtr.

There were some mentions of the knock off products on the gtr uk forums.

After a quick look on mishimoto website, the mishimoto fans were made for their mishimoto radiator with a core thickness of ~39-40mm from conversion.

The supplier of both parts was a highly respectable shop (Ztune out of Canada) with direct sales from these manufacturers. They've sold many of these parts without issues....

Ok fair enough, so they sold you a genuine radiator that won't fit and u can't return it cos they went out of business.

Are you sure the electric fans are suited not only for the mishimoto radiators? Their website didn't mention that but they said its made for their radiators. I guess fans can be made to fit with the right fittings.

As for your problem, sorry. I wouldn't know what to do in that situation.

If its that far out and whatever u do from now will only make it look ugly, either live with it as it's functioning properly or buy one that actually fits.

I think I've just found the problem after having a quick look at mine. The welding locations on the koyorad are perfect for the stock fan shroud. The mishimoto fans are made for their own radiators. Therefore, the combination of these two facts means you have two parts that weren't made to fit each other.

I was told that they do fit together as both are oem fitment however it's off... Here are some pictures of the radiator. It seems legit to me as was the shop for the last 4 years. They've sold everything from Nismo, HKS, RIPS, tomei, you name it... They closed shop cause the income was less than the cost of running the place and business was going down hill when they started charging more (shops around here charge up to $200 per hr... Anyways, I'll make cut the mishimoto bracket and get a longer one put on (3/16th longer) or custom make 2 small L brackets on each side....

why not use the factory shroud and clutch fan? Do I need to take picture for you that the mounting points are off for a reason?

The factory fan and shroud is heavier, more expensive to replace and is older technology. I like the electrics. I don't need pics thanks, I'm making my own mounts today. The fans are minor issues compared to my accusump I'm wondering where to put... was thinking of doing like the borg, up front but I dunno yet. Thanks for the help.

      @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s

      It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
