I'm hoping that I had one of the first batch mess ups and the manufacturing got better as time went on.

Have you done this before? I'll probably get it fixed and sell it then.

Ive used dura-fix a lot yes.

I would pay this price one time and be done with it. That's just me though.

Hmm, what Turbo kit do you have?

I have AAM. Coolant temps are better than when I had my GTM kit.. I think the reason is the AAM intercooler sits farther back allowing some air to bypass the intercooler.

I had a Mishimoto on my FBM turbo kit on my Fr-s prior to making the right choice on getting my Z. Ran it for about 2 years prior to selling that car and had no issues with fitment, cooling, or leaking. FWIW of course.

maybe it might we worthwhile to drop an email to info@koyoradracing.com

to see if we can show them there is enough interest to warrant production

^^^ if memory serves me right Koyo is working on a solution, but its just here say that I've heard from the great vine.

Has anyone here used the HPI with a boosted Z?

I would like to get the HPI but I have not heard anything at all about its performance and reliability, no reviews of any kind.

Adding to the mix. My car overheated due to low coolant. I had her towed home. I have been topping off the coolant every month since install and didn't mind it. Well, now I do. I sent CSF CS a email and gave them a rang. I got a hold of Ken and he told me to forward him my email. I guess I heard him wrong because I can't sent the email to the address he gave me (he was running out the door I think. It was almost 5pm). Anyhow, I'll have to call CSF again and see about that email address. Anyhow, Ken verbalized that warranty is 2 years from purchase date, not lifetime.

Well, lets see how this plays out. As is, I have a car down and lots of time and $ spent but I have faith.

I got a hold of CSF again and was told to email them again which I did.

:shakes head:

I tried to get help with CSF a few times. I called and spoke to Ken, sent emails to Ken and customer service. I got nothing. I was simply told to send an email and they would reply within 48hrs. Well, that was on 12-12-17. I have tried and called a time or two since then. I got nothing. What a waste of $$ and a piece of junk!!!! I will never again recommend CSF to anyone. $500 for a radiator, $ to evacuate and recharge the AC system the first time. Now that it's busted, I put my OEM one back on and now need to pay once again to have the Freon recharged. All this trouble, effort and LOTS of time wasted! I'm not one to pinch $$ or skimp on tool and work. I'm no prefessional but I consider myself very handy. Anyone that has read and followed my car build knows this.

So, as far as I'm concerned, CSF is total JUNK, TRASH,, RUBBISH! DO not buy CSF radiator. CSF is not worth the time, money and effort!

It suck that happen bro! When i did my turbo build that was the only area i didn't do in terms of cooling...the damn radiator. I have read too many problems with this aftermarket radiators that i just decided to keep running the OEM one and 3 years in and still running pretty damn good.

Seems like both radiators have their issues. :shakes head:

Csf 2 years now with no issues so far, also running boost as well

I'm glad it's working out for everyone. I invested in it. It was darn good when it lasted. But, it didn't last long at all. Personally, I don't feel like I got a lemon. There are too many issues with a supposedly drop in replacement. People having dripping drain plugs, drain plugs busting, leaking from cooling fins like mine. There is no way you can slap "quality" or "professional" on something like that.

I don't know what temps my car will run with boost and OEM radiator but it's better than $650+ down the drain and a tow ride home. I rather park my car and cool her down after a run or two down the strip than on the side of the road overheated like I was.

I have been running the oem radiator as recommended by my TT installer since day one just over four years now. I never had an issue with temps until I started tracking the car and Sebastian at Specialty Z and I discussed my options which did not include either of the two aftermarket radiators mentioned so far. The only one that he felt had any real merit was the Ron Davis custom radiator for the 370z. It requires modification of your front engine bay and you have to delete your AC. He suggested I open up my front bumper to let more airflow in before spending significant dollars on radiator change. So far that has worked even on track days over 100*.

The other thing you need to consider is that those aftermarket radiators are thicker than the oem and don't allow as much space between it and the intercooler therefore despite the other issues you may not make much headway on keeping your temporary down. Long story longer...stay with your oem. Just my two cents worth of nothing lol!

Sooo you’re still running a oem rad?

Lol, yup! I also started using Water Wetter as well. I don't drive the car if temps get down in the 30's which is only for a few hours when there is a cold spell that comes in.

If mine ever goes south I’m going back to oem myself

This is good advice. So need for CSF or Mishimoto junk on a boosted car.

I'm currently on my third CSF radiator and this one is the updated version. It's been installed now for 3 years and started leaking about a month ago. I'm officially giving up trying to have an aftermarket radiator in the Z and will return it to stock very soon. I will say, when I notified CSF of my second radiator's failure they did replace it for free, as it was not the updated version. As much as it would be awesome to replace this one, I am just ready to not pay for a radiator install anymore.

I'm totally with you. If CSF had contacted me and offered a new revised one, I may have bitten. However, they were nowhere to be seen even after contacting them. So BAD CS and BAD PRODUCT = suck.

I totally feel you on having to replace it over and over again. That's why I said "revised" product. The down time and uncertainty of driving a non reliable car is not worth it.

Here is the another thing to consider as some unfortunate folks found out. Unless you water temperature spikes while you are losing water you will never see a change in water temperature when the tank has gone dry....because the temp gauge is reading the ambient temperature and without warning your engine goes boom!

One of the reasons I installed an aftermarket water temp gauge. The sensor is in the upper radiator hose.

Me too but boy was it a ********** to get that silicone hose on with the fitting in it.

Here's mine.

Yeah I need to get that and an oil pressure gauge.

What size is the inline sensor adapter?

Thanks Rusty!

:tiphat:

This is not just for the 370z, it is for many other cars also. The 300zxtt and 300zx from 1990 to 1996 were the same way.

That’s the one

Ordered and shipped. :tup:

any reason you guys don't feel like removing the thermostat housing, drill and tap, place sensor there?

would look so much cleaner, not create more failure points and achieve the same result?

I’d rather have a purpose made piece than drilling a cast piece. I’m also a function over appearance guy.

Plus there is no good place to drill and tap on the housing. Not enough room and it's too thin for threads.

time for new billet product... ?
