You just have gotten all of your money from the military.

anyways. Im sure anything will be fine, its a cap.

if its a Nissan Rad (which im sure it is)
A Nismo Rad Cap will fit, I have one

Any cap that fits the stock rad should be fine. I replace my cap each year. After the first year (my Koyo came with a Koyo cap) I've just used an OEM 300zx cap. They come 16psi rated from Nissan (I think stock 240 is 14psi, but can't remember) and are cheaper (~$20) from my local dealership than most aftermarket caps, esp. when you factor shipping.

No... For 2JZ's Koyo caps only....

My friend had a 2JZ Koyo, and Greddy and anything else didn't fit....

guys,

It's a S14 with 2JZ swap and i'm having KOYO N-flow rad to cool things down. So does the KOYO come with a cap? or i should look into one?

there you go

OP, My Koyo for my SR came with a cap when I bought it yrs ago, maybe Koyo sells them separately now, e-mail FRsport to get the final say so. They are quick to respond. If you're using an S14 Koyo rad and adapting it to work with the 2JZ, then a Nissan cap will work, if you're using a rad designed for the 2JZ and adapting it to fit the S14 chassis, then you'll need a cap designed for the toyota 2JZ. Either way, if it's a cap that fits the stock rad (nissan or toyota) it'll work.

I have an Apexi one on my Koyo... that cools a 2JZ car as well. works just fine and dandy.
