Wez Posted October 12, 2008 Share Posted October 12, 2008 Hey All, I am thinking about changing my rad for an alloy unit, I think they might be a little more durable than the softer core stock units. If you had choice between Koyo and Fluidyne which would you choose and why. Quote Link to comment Share on other sites More sharing options...
tDR Posted October 12, 2008 Share Posted October 12, 2008 As per other thread - I chose Fluidyne and for me it was between the two also after having seen Koyos on other cars. I made this decision based on dusty's opinion that the Fluidyne is the least hassle to fit and slightly better made and I'm not disappointed. Cheers, Brian.

Wez Posted October 12, 2008 Author Share Posted October 12, 2008 Thanks. I would want to fit the stock cowling etc back and a hassle free fit would deff push it higher up the chain. Quote Link to comment Share on other sites More sharing options...

simbasupra Posted October 12, 2008 Share Posted October 12, 2008 I have a fluidyne. Havent got anything negative to say about it.....its been faultless. So is the fluidyne an exact fit? no mods required? Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted October 12, 2008 Share Posted October 12, 2008 I just fitted a Koyo to mine, cowl and assorted brackets fits perfectly, dropped into the 2 holders perfectly Quote Link to comment Share on other sites More sharing options...
tDR Posted October 12, 2008 Share Posted October 12, 2008 So is the fluidyne an exact fit? no mods required? Yes exact fit - cowl goes on no problem, it drops into the rubber feet fine and the top brackets line up fine. Comes with it's own rad cap.

RobSheffield Posted October 12, 2008 Share Posted October 12, 2008 Yes exact fit - cowl goes on no problem, it drops into the rubber feet fine and the top brackets line up fine. Mine does all that but has a shorter name - thats bound to mean it weighs less and performs better Quote Link to comment Share on other sites More sharing options...
tDR Posted October 12, 2008 Share Posted October 12, 2008 It's shorter so it performs better?!? Any women in the house??!? Quote Link to comment Share on other sites More sharing options...

Dazzi Posted October 12, 2008 Share Posted October 12, 2008 ASI, similar to fluidyne but much much cheaper. And no its not cheap quality crap that breaks before anybody starts boarding the bashing boat. Quote Link to comment Share on other sites More sharing options...
johnd-mkiv Posted October 12, 2008 Share Posted October 12, 2008 Ive had both But prefered the look of the koyo + it comes polished ive got a feeling it might be slightly larger capacity too Quote Link to comment Share on other sites More sharing options...
Mike M Posted October 12, 2008 Share Posted October 12, 2008 (edited) My Koyo was a perfect fit no cutting or clearancing but the stock fresh air inlet wont sit on top due to the width of the rad. I'm sure Thorin fitted the fluidyne and had to cut away some of the fanshround to clear the bottom hose outlet. Heres a few pics of mine, lovely rad. http://www.mkivsupra.net/vbb/showthread.php?t=144829&highlight=koyo+rad Edited October 12, 2008 by Mike M (see edit history) Quote Link to comment Share on other sites More sharing options...
Guigsy Posted October 12, 2008 Share Posted October 12, 2008 my fluidine is shiney... Quote Link to comment Share on other sites More sharing options...
Kev.O Posted October 12, 2008 Share Posted October 12, 2008 Taken from the other thread: I wouldn't recommend Fluidyne. Mine needed to be straightened, it doesn't sit perfectly in between the rad clamps, and it had a very small leak in it Quote Link to comment Share on other sites More sharing options...
JamieP Posted October 12, 2008 Share Posted October 12, 2008 LeeP fitted my fluidyne today and the stock fan shroud does need a tiny bit of trimming to clear the bottom hose outlet, also the top hose outlet is slightly nearer the center of the car than the stock one meaning my hard top hose dont fit quite as well now and is buldging the silicon pipe a tad (you can just make it out in the pic) Lee is going to sort this when the car goes in for its winter makeover. So all in the fluidyne is not a direct fit but it is very close. Quote Link to comment Share on other sites More sharing options...

paul mac Posted October 13, 2008 Share Posted October 13, 2008 had a fluidyne on mine now for nearly 4 years, and pretty much plug and play instalation Quote Link to comment Share on other sites More sharing options...

I can only assume they didn't actually fit it themselves. It's fine though and I'm happy with it. I know the PWR can be a bit of a *astard to fit, due to it being quite a bit larger I believe. If Rob says the Koyo is a perfect fit then I'd believe him, if he's lying I'll hunt him down and kill him. Quote Link to comment Share on other sites More sharing options...

Easier to maintain than a chrome engine bay too, less time polishing, more time driving! p.s wheres the polished power steering reservoir!?

Nic Posted October 14, 2008 Share Posted October 14, 2008 (edited) If you had choice between Koyo and Fluidyne which would you choose and why. Neither, I'd personally fit a Power Enterprise radiator. I use to have a Fluidyne rad fitted, it coped with everyday driving okay, but when really pushing it on a hot day or on track (drifting), temps started to rise. I swamped to a PE rad and this coped much better in all conditions, fit and finish was also better than the Fluidyne. Quite a bit more expensive though. http://img181.imageshack.us/img181/5938/1jza80powerenterpriseranf8.jpg http://img213.imageshack.us/img213/3220/2jza80powerenterpriserauq4.jpg Edited October 14, 2008 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...
michel lane Posted October 14, 2008 Share Posted October 14, 2008 I have had both , only one problem with the Fluidyne, is that you have to use the rad cap provided with it . You cant use a stock cap with this unit. The koyo uses a supra Mk3 fitment , so you can change between the caps on pressure. Also the koyo is thicker. I have had mine for the past 3 years and run a 1.1bar cap. Its fits perfect and the twin fans do a great job on it . The water temps are usually around 80 degrees, i also run a trd thermo aswell 79 degrees . Quote Link to comment Share on other sites More sharing options...
Jazzy Posted October 14, 2008 Share Posted October 14, 2008 only one problem with the Fluidyne, is that you have to use the rad cap provided with it. On my Fluidyne cap it says 16pounds which I assume means 16 psi, effectively 1.1 bar i.e. like stock Quote Link to comment Share on other sites More sharing options...
