Well, I got a PWR radiator, only to find that it isn't a direct fit -- at least not for me. I found that the brackets sit too low, causing the radiator to rest on the bolts. Has anyone had this problem with the PWR raditors?

 

define "rest on the bolts".

 

my PWR was a straight drop in. no fitment issues at all and thats including my m2 intake.

 

Whoops, what I meant was that the radiator BRACKETS rest on the bolts -- the bolts don't go in the hole.

 

The upper mounting bolts are attached to a rubber grommet, so they'll swivel around a bit to fit. And the brackets don't really have a "hole", more like a slot. You sure the rubber grommets on the bottom of the radiator are fitting correctly, and you're not having any clearance issues with the radiator fan brackets hitting something?

 

Yeah, I got the fan issues solved (cut out parts of the shroud that hit pipes). The bottom is in with the rubber boots -- but the top is giving me problems. You say that the top bolts on the frame can swivel?

 

Yes, they're basically set into a rubber grommet, so you can move them around a bit. The rubber is there to isolate the radiator from vibration.

You need to be absolutely sure that the radiator fan bracket is not hitting anything, as that will cause problems with getting the brackets to line up (like I did with my Greddy SMIC).

 

hey kento,
looking at your avatar it seems that you ride. if so please watch out for your bike because the theives are out in full force in socal. lost my r6 monday....

 

Wow, that sucks. Sorry to hear that. Actually, some guy who parked his Hayabusa out in front of my place (didn't know him) got all his bodywork and exhaust stripped off the other night. ******* thieves should be hanged by their gonads...

Sorry to get off topic....

 

I had the same problem, and had to modify the brackets a bit. A comparison with the stock radiator made it clear how much bigger to make the slots.

The good news is the change was simple.

Additionally, one of the bottom "pins" wasn't quite straight. This made for a pretty tight fit. The build quality is otherwise quite good.

 

Did you have a PWR radiator? I'm filing down the slots so the they are deeper and wider... I hope it works.

 

Yay, it worked! I needed to modify the existing brackets in order for the radiator to fit -- direct fit my ***!

Thanks for your help, Gene!

 

no prob, we should meet up sometime

 

Yes, a PWR radiator.

 

Definately! I could install those brackets for you.

 

Yeah, RX7Store shouldn't advertise this as a "clone" of the Fluidyne -- as it doesn't drop in directly without modifications. Had I known this, I would have gone with the Koyo.

 

Yep, exactly the same thing happened to me...

 

Koyo is suppose to be the biggest bitch to get in, requires cutting, fabing, bending, and a lot of sweat and tears.

 

I'm about to buy a radiator. Was leaning towards the PWR but if the Fluidyne is a true direct fit then I will shell out the few extra bucks for it. What do you guys think? Will the Fluidyne go in easy(easier)? Thanks.

 

Buy the Fluidyne.


Glad to hear that you are getting things worked out

 

DOES KENTO RIDE. i guess some people just dont read sport rider do they Kento is the man.

The modifications are very minor. The PWR radiator is inexpensive and well made. I wouldn't let drilling two holes stop you.

 

Im happy with the koyo it was a direct drop in. I dont consider bending two tabs at the bottom a TASK. ive done harder, ive put fuel in my car. If i had to do it again, i might go with a Fluidyne. Why...just because it is stock sized. i fear a few things wont fit with that slightly larger radiator, or am i over reacting.

It really depends if you want to modify anything -- if you don't mind doing a little filing/bending, then go with the Koyo. If you want a *DIRECT* replacement, get the Fluidyne. Honestly, I would go with the Koyo -- it has a higher capacity than the PWR and the Fluidyne along with a much lower price tag.

Although the PWR is a nice radiator (well constructed, 50% larger), I would go with the Koyo since it also requires slight modifications to fit.

 

In a little while, I will be selling my M2 radiator (about 15K on it). This is essentially a drop in. The guy that put it in (because I was a lazy ****) put it right over the OEM and liked what he saw in terms of lineup. The only thing you have to do, which you have to do with most radiators, is try to lower how it sits if you have a CAI. I have an M2. In the end we didn't move the radiator, we carefully trimmed the hoses to get the M2 CAI to sit back further.
