Cooler Si

[Eighty-Nine Si]

I want to upgrade the cooling on my '89 Civic Si and I once read that you can drop in the wider Integra radiator without interfering with A/C etc. Could anyone verify this.

how old is your radiator and why are you upgrading?
i would look into a new OE replacement radiator, should help a lot
or even a better electric fan instead of the stocker...

you having overheating issues?
or going boost? motor swap etc?

The radiator is about ten years old. I am installing a ZC and hope to drop on a JR supe next spring. It is running a bit hot now with the 185K SOHC and I figured that since an OEM Integra radiator will cost about the same...why not build in a little headroom? Good idea/bad idea?

sounds like a good idea to me
how much bigger is it?
and does it mount in the stock locations?

i honestly don't think a new OE radiator would have trouble cooling a SC'ed ZC, but if you can make it look decent and its the same price then go for it
