Engine, supercharger, etc. I would lay out pricing so you can see what it boils down to, also remember if you are ripping out the radiator it is cheaper to throw in the new fans now than later in terms of labor.

Yeah I just read your review on it.. Seems like the radiator itself would serve just fine.. but you're correct in saying if I'm already gonna be in there, might as well do it all at once. I'm trying to find a site that has the fan assembly to order along with the radiator.. I'm having no luck so far.

I'm in jersey and was thinking of getting radiator upgrade myself. I didn't. I just got gtm 25 row oil cooler with spal fan. During late summer at around 90F whether, my oil temp wouldn't go past 200 even if I tried. Unless you are tracking the car, radiator upgrade is not really necessary for our east coast temperatures. I suggest to spent that extra cash on good monitoring and then upgrade in the future if necessary. At least that's what I did

You're not going to see much of a difference in oil temperatures from a radiator. It'll definitely lower coolant temperatures though.

I decided to upgrade mine for a couple reasons. The first as fryzia pointed out, weather in the desert is harsh, the second is all the other heat exchangers that are now in the way. It was painfully expensive, but for my own build, it was the right call. Now... If someone wants to buy my twin 19 row oil coolers, I'm thinking of upgrading to 25's haha. I was a bit miffed to see oil temps jump 20 degrees when doing a 5th gear pull on the dyno lol. Went from 200 to 220 and took a few min to cool back down.

Exactly. This is why you upgrade the radiator. You've stuffed an intercooler in front of it, and at least one oil cooler. You've compromised the ability of the OEM rad becasue it doesn't get cool air anymore. The only reason you don't see this reflected on the water temp display is that it's inaccurate and useless.

Voice59 · 10-30-2013, 08:08 AM

Would the radiator itself without the fan suffice for the application I'm trying to do. I'm not tracking the car. Just occasional spirited driving.

Chuck33079 · 10-30-2013, 08:09 AM

You won't know until you do it. I regret not getting the fans when my radiator was installed, but we didn't know they would work with the CSF rad at the time.

Don't TT's generate more heat than SC's though? AND you're in Texas.

These cars always run hot, even a completely stock car could see some benefit from upgraded radiator and fans.

If you can afford it, get the full setup, if not, skip on the fans, you'll probably be fine, especially if you never plan on tracking it.

Right, at this point I have no desire to track it. I may go to the track once or twice. And it's literally just to see how much quicker it accelerates and what my top speed would be after a tune (if that changes at all). Can anyone provide a link to where I can get the fan? And also does it add any significant noise while running?

I got a question for you Sh0vel. I see you have stance coilovers, are you running camber arms with those? I just recently bought an SPC rear camber kit in preperation for getting my Stance's installed. I'm just making sure I went the right route.

I have front upper arms, I have stock arms in the rear. I run more camber than you would want to run on the street, most likely. Makes the tires wear weird.

The coilovers have almost nothing to do with alignment though. The need for aftermarket arms and whatnot is based purely on how low you want to go. The Stance units are capable of basically stock ride height (at least on my car, yours will be substantially heavier, so your mileage may vary), making the stock adjustments satisfactory (for now). I definitely sit a bit lower than stock, but I'm not slammed by any stretch.

So, in summary: It'll depend on how low you want to go as to whether or not you need aftermarket arms.

Maybe. I was just barely out of spec, and I was only running Eibachs. I went ahead and bought front and rear arms, and rear toe bolts. These tires cost too much to burn them up by being out of spec.

I'm looking at eliminating wheel gap. Maybe not completely, but definitely not where I'm at right now. Just doesn't look good.

They do since they use coolant to cool the turbos, but you're stuffing a hot intercooler in front of the OEM rad and using the stock fans to pull air through it. Compressing air generates plenty of heat on its own.

The GTM fans are less than $500 on a build that's probably over $10k for the sc kit and assorted other stuff.I'd rather overbuild than try to get by with the bare minimum on a project.

Somebody posted a video, it is louder than stock, but not obnoxiously so in my opinion. Your top speed will be higher simply because the speed limiter is removed. I haven't seen anyone take a FI Z out to a standing mile type event to get a real top speed.
