well i'm in the process of installing my blitz FMIC and was wondering what is the best upgraded radiator i should purchase for my 7...

 

Koyo makes really good radiators. Check their products out

 

Depends on how much work you want to do, I have a koyo and it took a good bit of time to fit in cus its not the greatest fit, but its the largets I do believe. Another popular one is the Fluidyne which is around a $100 more but usually fits a bit better. I got mine from rx7trix.com and they matched the best price i found and shipped for free.

 

i just got done installing a fluidyne radiator from rx7store.net. Perfect fit and had no problems getting it in. Still on stock ic if it matters. Car is a 93 R1

^Old thread, but still worth reading. A search will give you more.
Fluidyne= 50% larger stock
PWR=50% larger than stock
KOYO= 100% larger stock (but seems to have more fitment issues)

 

 

thanx for the advise guys... but i decided not to go Front mount and just got a large stock mount... soo i have a used FMIC for sale... any interests?

 

i had an over heating prob because my radiator decided to take a **** so i got a fluidyne n that works really really good

 

i went with the mazda comp radiator, with the FINS on the side, lil more seperation when it comes to airflow. but im very happy, worth the chunk of change lol

 

I also recommend the Ron Davis / Mazda Motorsport radiator. Thinner that both the Koyo and the Fluidyne, but "supposed" to be highly efficient because of the split-fin design. More expensive too.

Never seen any hard data proving the performance advantage, but I'm a big fan of "quasi-OEM" parts. They usually work right out of the box which is more than can be said for a huge majority of aftermarket "doodads".

Example... the "bigger is better" Koyo will require a little bit of extra work if you have other mods going on underhood. Do a search on this. A lot of people have spent an inordinate amount of "swear-grease" putting one in.
