Here are some pictures I took of my Mishimoto MMRAD-EVO-01 radiator (the part number for the OEM replacement radiator for the Evo 7, 8, and 9). When I was researching radiators I couldn't find good pictures of the Mishimoto radiator to get a feel for the weld quality and consistency, so maybe this will help someone else out to make their decision.

Some basic info...

Weight: 12.52 lb (with included radiator cap) for comparison, the OEM Evo9 radiator is 9.90 lb. with the OEM radiator cap

Drain plug: aluminum with a rubber o-ring; mine came with teflon tape wrapped on the threads, takes a 24mm wrench or socket

Inlet/outlet diameters: 35mm

The OEM Evo radiator's inlet and outlet pipes are a hair bigger at about 35.5mm, so it might be best not use the OEM spring clamps with the Mishimoto radiator as they might not clamp down tight enough. I replaced them with Breeze liner clamps; since the OD of the rubber hose is about 45mm, the Breeze 9224 or 9424 clamps (27–51mm effective diameter range) would work well.

Install notes: Fitment in my Evo ('06 IX) was excellent overall. The mounting posts for the two top brackets were both off to the passenger side about 1/16"—enough to notice/be slightly annoying, but not enough to make it not fit well. The inlet and outlet pipes are in the right places for the OEM radiator hoses. The welded on bottom posts fit the OEM rubber isolators perfectly.

I don't run the OEM fan/fan shroud anymore, so I can't report on how the mounting posts for that aspect of the install line up.

















































Installed:





The clearance from the back of the radiator to the wastegate actuator is about 1/2"... it's adequate, but you need to be very careful not to damage the radiator when R&Ring a turbo or the radiator itself (just like with the OEM radiator).





I also built my own mounts for my SPAL electric puller fan... it's just metal strap spraypainted black. Looks a little funky because of the location of the mounting points on the radiator and the frame of the fan, but it's very secure and only weighs about 3 ounces.

is it more efficient than stock?

I used this radiator in my car for over two years, after the stocker failed. I worked perfectly fine on my car, which I dd, track, and autox. The stock upper and lower rad hoses also didn't have any issues. Its a bit thicker than stock, so it made for a tight fit with the stock UICP. Other than that, it worked great. A few of my friends are also running it without any issues. I think its a geat alternative to some of the more expensive ones on the market.

Have one for about a year. The Mishimoto cap leaked, which is something I think they are aware of. But otherwise it has been fine. The car does cool faster that with the stock, and the capacity is higher. So you overflow tank will have more fluid on hot days/ drives.

it is a little deeper, but no worries overall. I used my existing greddy cap and has not leaked since.

The cap is covered under Mishimoto's warranty as well if it does leak; my understanding is that they'll send you a new one if you have a problem with it leaking.

I have not had the chance to run my car at the track with this radiator yet, which IMO is the true test of cooling capacity/reserve, other than maybe stop and go traffic on a 110+ degree day, which my car wouldn't be subjected to since it doesn't get used as a street car much anymore and it doesn't get that hot in the summer in Colorado (but maybe it will in another decade).

I added some pics to document the clearance to the WGA... on my car, with the stock-frame turbo and exhaust manifold, the back of the Mishimoto radiator is about 1/2" away from the closest part of the end of the wastegate actuator arm and the cotter-pin clip thingie.

I often hear people bash Mishimoto, so it will be good to follow this thread and see how this radiator works out for you.

I'm only planning to do NASA Time Trials events (maximum of about 25 minutes of beating on the car per session) rather than actual road racing. Also, my engine is "only" making about 500 whp (corrected), so it's not an extreme example of heat production from a 4G63 motor.

I'm not expecting this radiator to last forever; I've learned the hard way that there are plenty of expensive Evo components (say, transmissions, clutches, transfer cases, and even engines) that don't last nearly as long as you'd hope after spending lots of money on them. In the grand scheme of things, the cost of a Mishimoto radiator is chump change.

In fact, if this radiator were to crack or fail after a couple seasons of hard use, I'd still be satisfied with it, especially if Mishimoto honors their lifetime warranty and gives me a new one for the cost of shipping the old one in (maybe $35?).

But yes, If I experience a failure, I'll report it, and document how Mishimoto handles it as well.

Well just purchased this radiator, I was debating between a Koyo an Mishimoto and then between stock route upper radiator hose or evo 6 upper radiator hose. Just opted for Mishimoto evo 8 radiator, mainly because of the price and reviews seen here. Once I get it I will post some pictures and feedback as to how the install goes.

I have one in my car. It has about 60k miles on it so far, and over 10 trackdays(30 min sessions flatout at ~380whp, a couple in +100deg tracktemps). The cap is a weakpoint, get rid of it and replace it with a stock one, otherwise it's a good buy. I'd get the one for the evo6 that way you can move the upper hose over and make it straight as opposed to being over the exhaust manifold.

ive had my mishi rad for over probly 40k miles and never had a problem with it. you cant beat it for the price and the warranty

I have been using the mishimoto evo 4/5/6 radiater for the past 5 years 80,000+miles with o ut a problem. I recomend the evo 4/5/6 radiator over the evo 7/8/9 radiator because its 100% the same but the upper radiator hose is moved to the driver side so that its away from the heat of the turbo manifold.

Here is mine

M8NSTER

I had their 8/9 rad for about 3 years. Right away I had a problem, but like said before, their customer service was top notch. They replaced it free of charge and that one ran with ZERO issues for 3 years. I just replaced it with a 4/5/6 rad because of my turbo kit. I would also recommend this one over the 8/9 because of the top hose placement.

Very cool review you put together!

I love Mishimoto's products. I personally have one in my 240sx and have never had a single problem with a 3+ year old rad. Holds up great to the high engine bay temps that are reached while drifting.
