need to know where i can purchase a koyo radiator cap for my aluminum koyo rad (polished) not oe replacement

 

...don't know if this will help, but on my GSR my Fluidyne radiator needed one from a Prelude, same year - 97...

 

IS IT .9 OR 1.3

 

1.3 is most likely overkill. I'm not familiar with your setup, but I think you'd be just fine.

 

WHAT IF THE CAR IS BOOSTED

 

will the cap size affect the performance of the car and arent the KOYO caps 1.3 anyway????

 

I would just go and get a brand new OEM cap. Don't get a higher rating, it puts more stress on things like hoses and the headgasket.

 

ok i guess i will get a new oe one cause the one on there now

how can it put stress on hoses and the headgasket?? and why are the koyo caps 1.3

 

DO U KNOW OF A RAD CAP THAT IS STOCK SPECS BUT WILL FIT THE KOYO RADIATOR???????

LIKE WHICH ONE WITH A PART NUMBER

CAUSE I DONT THINK THE STOCK TEG ONES FIT

 

As far as I know, the 1.3's increase the pressure in the radiator.

I believe i've heard people using SPOON rad caps.

Anyone else have any input on this?

 

YEA BUT I HEARD ITS BAD TO PUT A MORE PRESSURE CAP ON THE CAR

READ THAT LINK I POSTED 2 ABOVE THIS ONE

SO IM LOOKING FOR A CAP THAT WILL FIT THAT IS THE SAME PSI AS THE STOCK CAP

 

bump

I doubt that 19 psi (1.3 bar) in the cooling system will stress a headgasket that will seal over 5000psi of hot gases when the charge ignites...

If people neglect their hoses, they can fail even at 13psi (0.9 bar). Plus, it appears that he has a welded Koyo radiator so it should hold the extra pressure.

there are two Spoon caps. which one fits?

88-91 CIVIC, 90-93 INTEGRA
or
92-UP CIVIC, 94-UP INTEGRA

if i remember correctly my 94+ integra cap did not fit my Koyo. i had to go buy the OLDER version (90-93). can anyone confirm this?
