okay well im trying to talk my dad into leting me swap in a b18 and stuff and this is one of his questions. was what kinda radiator would i need to swap in after doing a b18a1 swap to be exact.

 

Whatever radiator you've got, a D-series radiator will cool a B18 just fine.

 

cause my dad didnt think it would work with just upgrading basically to a slim fan or whatever. cause he thinks since that raditor is meant just for the d-series it wouldnt be enough to cool a b-series since it's the half-size radator.

Just make sure your water pump and thermostat are good.

 

Use your stock one. It is perfectly fine.

 

There are plenty of us who are running half size radiators w/ B18s + turbo. Right now I'm running a b18c with a half rad and it works fine. On top of that, I live in AZ where it gets to 115 in the summer.

 

score thanks guys just one less part i can knock off my shopping list.
