Mishimoto Radiator good?

[E2EKIELR34]

ok ive been searching around for some radiators and was going to get a koyo until mishimoto came up. from what i read, its exactly as the koyo but cheaper. is it worth it since its a hella cheaper then the koyo. are they exactly the same. also ive heard that the shroud and fan fit and some people say it doesnt fit. i just want to clearify if it both the fan and shroud actually fit. anyone have experience on these radiators and their opinions. thanks a lot. and this is referring to a KA S14.

koyo is already cheap enough

not cheap enough for you?

save more money

its a radiator, i wouldnt take chances

use what is tried and true

id say that koyo is probably on like 75% of SR swaps (and KA upgrade cars) out there

and no, i dont sell koyo so i have no reason to say this

and yes i use koyo on my car

[Dousan_PG]

no shit
stop cutting corners.
i use a fluidyne now
used to have a koyo.
both work great.

[Farzam]

Cut corners on your sandwich.
Not your car.

[LB.Motoring]

Yup, Used Koyo, dont buy something else,

thats cooling, its important, thats like buying a fake heart defibrillator, because its cheaper than the real one.

[DriftSpecS14]

fluidyne i hear run 10 degrees cooler then koyo!?

[FRpilot]

koyo i hear overcools

[CKAMC]

koyo i hear overcools

Overcools!?!??!? Thats the first time I have ever heard that! :ugh:

[sideview_180sx]

damn radiator works. direct koyo copy. even down to the fin count. and weaksauce filler neck. fluidyne and C&R are hands down much better then koyo. gotta pay to play. remember you need to have fan shroud to actually have a positive cooling effect.

koyo i hear overcools

No, that was just Sub Zero.

be baller, get yashio factory!

Many honda guys run the Mishimoto with good results.

[all stock]

i'm running the mishi, 240sx its race prep, it does its job just fine. decent quality fins and plate. welding is pretty good too. larger size than most.

the only downside is the cheap drainbolt. easily stripped, i had to retap mine to a larger size. i'd suggest taking out the oem one and utilizing that.

[viscid240]

Don't cheap out, Fluidyne, koyo, C&R, PWR, and others are very good. If it's that cheap and it fits your bill go for it. Just don't complain or kick your self that hard when you should have went with something more tried & true.

[axiomatik]

i've heard koyos aren't that great. I would go with fluidyne or griffin.

[DOOK]

had griffin on my jeep, will have griffin on my Schassis

What you didn't compare was the area inside, its thermal conductivity of the material, and thickness of the walls inside the radiator. Just one of these can change your results dramatically.

Its definetly better than an OEM one just judging by its appearance, but to say its the same as X aftermarket brand can't really be said just by looking.

[turtl631]

I doubt Koyo is much better than Mishimoto if at all, Koyo is a pretty chintzy rad. Look into using a universal summit racing rad, or the copper koyo they found to work well on the FA fan test. Lots of info on rads out there.

[arkive43]

lol isnt mishimoto a sponsor on this site?...

[DOOK]

no, but sponsors for the site sell them

[Ian]

I've got an ebay radiator, no doubt the same as the "mishimoto" one (isn't that the fake name for tires they used in the fast and the furious movie?...mishimoto zx tires right? haha)


it works fine, on the track at high rpm's for extended period of time...just as good as koyo

[bboyt3nsk]

be baller, get yashio factory!
Good advice!

I had a KOYO on my SR for awhile and worked well.

[surge s14]

i have a mishmoto rad works just as good as a koyo FYI

[k's_silvia2.0]

koyo i hear overcools

Well you heard wrong cause ive never had a problem
on start up or running around all day in the summer.
QUALITY FTW.

[turtl631]

A rad can't overcool, unless you don't run a thermostat in your engine.

[Dousan_PG]

right!
no thermo for the track car is fine
thermo is need for street or it wont really get about 60c!! yikes!

[smurfgcr]

im running a mishi in my s13, and it does the job just fine. like stated above the only thing that blows on it is the drain plug stripping situation. anything is better than stock though.

[mamsport]

Griffin for a track car WWW.ma-motorsports (http://www.ma-motorsports) sells them and will modify to you specs

[DOOK]

hmmm, vendor much huh? Why don't you buy a vendor thing from the site and start officially marketing.

[FRpilot]

be baller, get yashio factory!

forget yashio factory. you want baller? ARC probably has the best designed radiator and fins since they specialize in cooling. they cost about the same.

Well you heard wrong cause ive never had a problem on start up or running around all day in the summer.
QUALITY FTW.

by overcooling, i meant it takes too long for the car to reach optimal running temperature, not that it has start up problems or problems running around all day during the summer. i dont know the correct term for it, if overcooling is not right. one of my friend's stock sr radiator cracked and he bought a koyo. he didnt like the way it took forever for his car to warm up so he covered half the koyo with cardboard to block air from coming in and he only used a single altima fan instead of duals. it always cooled fine even after he did that. you can always just start your car and drive it around without it being warmed up, that's fine too.

actually, it was an older thread on zilvia that i read about griffen radiators. i believe dave, driftfreaq, commented on the koyos (but don't quote me i can't even find that thread). it was stated that the koyo was designed with too many cooling fins or they were too closely packed together and led to inefficient cooling, but because of its large core size and amount of fins it still works adaquately. even the infamous cooling fan thread, the koyo copper stock replacement oem spec radiator outperformed the large aluminum koyo. however, there are better and more efficient radiators like griffin and fluidyne to name a few.

i'm not trying to start a debate or anything. i'm just trying to spread some information on what i have read. maybe others who know more on the issue can shed some light. if not, let it die.

koyo's still work fine, and for the price (about 300) they are probably the best bang for the buck, which is probably why 90% of 240sx owners run them. they are decent quality, but you can opt for other higher quality and more expensive radiators in 500-600 range like greddy, fluidyne, griffin or super jdm expensive radiators like ARC, yashio factory, ings+1, etc in the 1000+ range. i will probably be doing vmount and end up buying a koyo as well since i'm going to be hacking it up/welding/experimenting with it.

but this guy thread poster doesnt even want to opt for koyo.. at the same time, he was just asking how the mishimoto radiator performed. i dont see the point in paying more if the mishimoto is the same thing as koyo and performs the same. i dont know much about mishimoto, but if they are ebay quality i wouldn't buy it. it's like ppl buying spl/stance coils vs more expensive jdm counterparts. why buy the silk roads, cusco, koguchi power, whatever spec when you can get stance/spl that works just as good for less.

i think everyone is too quick to bash on cheap stuff that isnt tried and tested yet. some things like certain megan parts that are tried and tested and break and crap deserved to be bashed but not something new and cheaper and untested yet. if no one ever asked about spl, stance, etc. then no one would try them. then we wouldnt know spl or stance is good quality and inexpensively priced and everyone would just say they are cheap and unsuperior and bash them being ebay quality. then we wouldnt have alternatives.

end.




ps. i dont know why some of my recent post have been the lengths of novels. does anyone even read them? i think some of the things i have to say are insightful and should be discussed, but this is not freshalloy. even i can't stand some of the many pages of research and debate on there with complicated theorums and such from engineers and chemists, but it is informative and i learn a lot from there too.

[sideview_180sx]

Umm......I find it funny how people care so much about the quality and what not. Most Japanese companies get there products from 1 factory. They just rebrand and resale. Coilovers, Suspension. Exhausts. No one complains about quality. Would you gripe if I used a cheapo rad from jegs. Or because its in jegs its quality?? As long as it cools great, doesn't leak, and can hold up to sitting in traffic in the IE all day. then it definately works. I have the fan shroud, etc. and that definately helps. The radiator is just one part of the solution.


Rant.

[gotta240]

Fuck this site is full of jackasses.........

Who bash shit they have NEVER TRIED, TOUCHED, OR SEEN, just because it cost less....

[guitaraholic]

Actually I've had a Mishimoto radiator for a few months now, works great, even in hot FL in traffic,, and I don't have an electric fan/shroud (yet). Not worried about it too much for a few more weeks (up in Canada), but no problems so far.

[hay_hay13]

i have a mishimoto and i haven't had any ill effects. working good imo. i admit i was skeptical about it at first but i read alot about honda and acura guys using it and loving it so i decided to try it out. my friend who has a koyo is actually impressed with the radiator but said it feels slightly heavier than a koyo but anywhoo it works and my car has never even gotten close to overheating

[EDacIouSX]

i want yashio for my KA :(

[Otis Performance]

i run Mishimoto radiators on all my rb swaps and i have never had any problems with any rb s14/s13 over heating.. what i can tell you is when i ran a koyo with duel altima fans and nismo thermostat this happen yo my rb.

sitting in rush hour traffic on the 91 freeway with a koyo radiator is bad news

[Tearlessj]

I have a Mishimoto, although I havnt installed it on my car. I went over it and everything looks to be good. I know thats not saying much but it "feels" like a good part.

[BustedS13]

i'm buying a mishimoto. i find it really funny when people say things like "pay to play" on here. we drive 15 year old nissans, not porsches. i bought my car because it cost next to nothing. i don't plan to spend a lot on it.

[Kaotik25]

i've been running a Mishimoto radiator for about 3 months and everything seems to be fine. I did a visual check around the weldings and the neck and everything is ok so far. I've been driving it under LA hot weather too.
