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.
