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.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
