Radiator: CSF or Mishimoto?
 

Price is close enough to not matter between the two.
Given that, any recommendations for one vs the other?

If someone has hands on experience with both that would be fantastic.

Thanks in advance guys.

Csf all day. Ive seen one of mishimotos radiators for another vehicle and build quality isn't even close.

Csf!

Setrab !?

My question is why are so many people buying radiators whatsoever? I heavly track my car and my engine temps have never gotten even slightly over heated. Oil temps used to but that was fixed with 34 row oil cooler. So why waist the money on a new radiator when the stock one is plenty sufficient, at least from what I have experienced so far.

Personally, I'm doing it as part of my TT build. Can't speak for others :)

Also, it gets damned hot & humid here :p

So 260 degree water is ok?
Come run a boosted car in Texas in the summer when the temperature is 100+ and the air temp off the ground is 110-120 on a daily basis. I think last summer I registered a 183 degree intake temp when sitting at a light once because of an accident and I could not move, black top plus idle plus 100 degree temp.

Oh and for the OP: CSF
Been running it for years and it has been great.

Love my CSF. Got it with the plan of doing a coolant to oil, oil cooler down the road.

Air intake temp has nothing to do with the radiator...but temps get up to 100 in chicago and very humid as well in the summer and with stock radiator and heavy tracking I never got engine temps even close to the 3/4 mark. I can understand if you have a boosted car engine temps might get a lot hotter than NA and so thats a diff situation. Im just saying as far as NA goes, I cant see why a different radiator is necessary at all.

I am just using the air intake temp to represent how hot it can get here. Meaning what real temps are like around the engine and not just using what the air temp is. Even when I ran N/A in Texas on hot day just going to the 1/4 mile and doing run after run I could get 250 quickly.

Hey Guys,

Just chiming in here to provide som information about the Mishimoto radiator. Our radiator will certainly provide cooling benefits in hot/humid environments as well as on the track.

The Mishimoto radiator capacity is almost double the OEM radiator which helps provide greater cooling efficiency. Our engineers did some data collection for this radiator that can be found in our engineering report here: http://lib.store.yahoo.net/lib/yhst-...ringReport.pdf.

I would be happy to answer any questions!

Thanks

You're coolant temp hits 250 by the end of a quarter mile pass?

Yep, I am N/A and water temps of 250F are not uncommon on track when the ambient temperature is high. I usually back off for a lap when I see it start to climb. Radiator upgrade will be next on the list.

He is boosted and this part of Texas gets stupid hot and humid. I run the CSF w/Mishimoto thermostat and have a COMP oil less turbo (which uses coolent) and I max out around 240 when racing/pushing it. Looking into SPAL fans for this season.

Why nobody considered GTM radiator?

CSF for the win! Boosted and in TX as well.

Never dealt with CSF but I had a Mishimoto radiator on my R33 GTR and I have one going on my 370z for a Stillen SC install. Never had any problems with the Mishimoto on my GTR and it was a perfect fit.

PWR...
Nissan Motorsports parts.

Would be great if they would get back to me :/

You could also try calling PWR direct (in USA not Australia :)). They might have it in their system instead of going through Nissan Motorsports.

I'm considering the GTM mostly because of the integrated heat exchanger for additional oil cooling.

After multiple passes it would hit 250, think of running the 1/4 mile, getting back in line and going again, repeat.
The other advantage aftermarket (CSF that I know of) has over the stock is how much quicker it will lower the temps. I could hit 240 and it would sit for 20 minutes like that without dropping at all, but with the CSF I can hit 220 on spirited driving and after I let off the throttle it starts going down at 30 seconds by 2 degrees.

Awesome! Great to hear. Thanks for the feedback. :tup:

Hey guys!

It's been a while since CSF was last active on the forum. saw this thread, and we wanted to add our 2 cents in hopes of helping the Z community with information on which cooling system to purchase if you are looking for an upgrade over the stock one.

Here is my unbiased opinon on what is available in the market.

PWR
pros: Good quality product, and they are the actual manufacture of their product. Used by Nissan motorsports teams
cons: manufactured in Austrialia so it is expensive + expensive shipping cost, no condenser available due to core thickness of radiator resulting in not being able to use AC

GTM
pros: large capacity + intergrated oil cooler
cons: modifications needed to install resulting in higher labor cost, not manufactured by GTM, very expensive (epesically when adding SPAL fans)

Mishimoto
pros:
cons: not manufactured by Mishimoto, made in China by contracted supplier

CSF
pros: B-tube technology (15% more efficient tubes) - used in GT-R,
- endorsed by Nissan Performance and Nissan USA - used in "Project 370Z"
- endorsed and sold by Z1 and Stillen
- all-aluminum drain-plug
- Available for both automatic and manual transmissions. (CSF#7012, #7011)
- detachable condenser component for serious racing
- wind tunnel, vibration, thermal cycle, salt spray, and burst pressure testing
- We actually manufacture all of our own product
- #1 Supporter of the Z community - it was great talking to everyone who stopped by our booth at Z-Nationals.
- Best value upgrade
- Most proven and most sold
- 50 years of cooling experience and manufacturing
cons: limited supply available

If you guys have any questions about our cooling system module, please let me know.

Remember: proper cooling is crucial to maintaining the logevity and stability of your engine, while allowing you to maximize power.

Lol!! Biased much?????

Of course he's biased towards his product. I would hope he liked his own product better than the competition. Any of the ones he listed other than mishimoto is a great choice.

A little biased understandably. The GTM unit is also built to order so has a 6-8 week lead time. You need the radiator plus their custom shroud which bumps the price up significantly. The integrated oil heat exchanger is pretty sweet though and can be used either for cooling the A/T or on a manual to boost the engine oil cooling efficiency. The condenser is removable if you decide to go all track.

The PWR would be my first choice for a track only application with A/C delete, solid racing reputation. They are stocked by Nissan Motorsports but ordering through Nissan is trying.

Also do you homework regarding warranty replacements (for street vehicles).

Anyone else who has gone with Mishimoto's radiator?

The results in the "confidential mishimoto files" posted before look promising. :P

I run a CSF on my 350z. Quality is top notch and fitment spot on. At least on the 350's the holding tanks are a bit wide (2-2.25") so it pushes the factory fan shroud fairly close to the pulleys-n-belts, but clears.

Mishimoto for 350's always had questionable hit-or-miss fitment especially the mounting pegs being off. I assume due to chinese production and lower quality assurance standards.

This ^^
I have an 08 G35 HR, not even boosted just idling in 56C (133F) ambient summer temps, water temp was at 110C (235F). That's just crazy. Between the insufficiently thin radiator, 95C thermostat and 98C factory fans temp setting, the cooling system is definitely shitty IMO.

I think both radiators look good. Mishimoto's videos are excellent explaining the details of the radiator and its installation.

However I think there could be problems for people trying to fit intercoolers in the car with Mishimoto's thicker radiator.
There may not be enough space for radiator + oilcooler + intercooler.

Someone with a turbokit has this installation?

I now own a CSF radiator and I will see how she hold up in the El Paso heat!

Any of these radiators will be sufficient. I personally have a csf radiator and its been great for me. I think mishimoto is trying to step there game up a bit with there new stuff. It will be good for there business for sure. As for a NA car you could probably get away with a big oil cooler but why take the chance and run your stuff hot like that. It will begin premature wearing of parts. No reason for these cars to be in 230s to 240s. Especially not when we have good solid options like we have. Also if you have a automatic z the radiator is also your transmission cooler so you def want that to be cool. Now when it comes to boosted cars. Most of is are running gtms turbo kit or some variation of it. So you have coolant and oil passing thru the turbos only to return to the radiator and oil pan. You strap on a oil cooler that takes car of that but that also blocks some airflow to the radiator and adds heat directly in front of the radiator. Also add the 3 inch thick intercooler right behind the bumper inlet and the heat that thing will generate under boost so it's easy to tell how overwhelmed and stressed the oem radiator is. Add a good radiator with a NA or boosted setup and your engine will love you. Your ac will be much colder, oil temps colder, I've even seen under hood temps go down. Trust me is down south know what it's like to be hot and humid 80 percent of the year. Chicago is nothing next to New Orleans or cities in Texas Florida ect ect.

They both need to get on the ball and get a upgraded fan and shroud plug and play setup!!!

Yeah but made in China gives me a sour taste in my mouth.

Spending money on GTM's option left me nauseous and my wallet empty. Thank you Red for picking it up btw, my parts sale softened the blow :)

No worries Thank you for the deal!

Yea that sucker is eeexxxpppeeennnsssiiivvveee!!!!! Would've made me sick also.

Our products are manufactured in a variety of facilities. Mishimoto is a global provider with offices in Delaware, Los Angeles, Birmingham, United Kingdom and Shanghai, China. All products are designed, engineered and tested in New Castle, Delaware at our corporate headquarters using state of the art machinery (CMM arms, AWD Dyno, Rapid Prototyping, etc.). The manufacturing location depends on the product we are manufacturing. For example, all of our intercooler pipes for diesel trucks are made in Los Angeles. Our stamped aluminum brackets come from Texas. The radiator referenced in this post is in fact made in China, under strict control of our American operated Shanghai branch. We actually do oversee the manufacturing as we have a supply chain office with 10 engineers that work in China and oversee the implementation of our USA designs. We try to make as many parts in the States as possible, where feasible. With that said, much like Samsung or Apple, it comes down to the engineering behind the part and the quality control of the manufacturing. With a lifetime warranty on every part we manufacture, it is safe to say our parts are of the highest quality.
