So my 93 EX currently has a cheapo Ebay aluminum radiator in it. And I have never been happy with the way it fit and I have never been able to get the bottom hose clamped on it well enough that it doesn't have a tiny leak.

Looking for suggestions on a good drop in replacement. The car is basically an autocross car and is eventually going to have a turbo D-series build. I saw Koyo, Mishimoto and Yonaka. Anyone used in of these brands?

 

Has been covered numerous times before, and also recently.

Koyo, Go-Autoworks, CSF.

 

I second Go Autoworks. The Koyo rad I had touched the hood which could allow electrolysis but also got damaged everytime the hood was closed. I took that out for the much cheaper Go Autoworks. Four years and 85k miles later it's still working fine.

 

denso and spectra are also good choices for $80 or so on fleabay.
