i need to buy a new radiator for my 88 na and im thinking of just upgrading it to a better one but i dont know which kind to get. any help?
i am going to be going to school and it gets really hot over there i dont know if that changes anything. thank u in advance

 

A Koyo is a direct fit, and can be had for around $300: http://www.rx7store.net/product_p/koyofc86.htm. The side straps from an OEM radiator unbolt, and attach to the Koyo. If you already have an aftermarket radiator in the car (no plastic end-tanks), you won't have the straps to mount it.

 

thanks man
it wouldnt make a difference if it is convertible right?

 

^probably not

 

alright thanks man

 

Koyo is a good choice! make sure that you pay that tiny bit more and get the triple bypass N-Flow type!

 

The N-flo Triple Pass one is a S5 radiator. It can be made to work, but you'll have a second radiator cap & overflow tube because the S4's cap & overflow tube are on the filler neck (on top of the water pump housing). The S5 moved these to the radiator itself. It will bolt on with zero modifications by re-using your S4 radiator brackets. If the brackets are stuck on the stock radiator, I'll give you mine (from 87 GXL) for the cost of shipping
