Does anyone which radiator hoses are need for this application? 95 EX with OEM EX radiator and JDM B16 motor? Also which thermostat-99-2000 Si work?

 

'94 - '97 Del Sol Vtec upper and lower hoses should both work fine. Thermostat from a '99 - '00 Si or '94 - '97 Del Sol Vtec will work fine.

 

^^ this, and use your stock EX hose clamps, for the radiator, and the dohc clamps for the engine.

 

Not quite, you need adjustable hose clamps on the rad end to squeeze the larger hose on the smaller inlets on the D-series rad.

 

yea hose clamps work well too but you might want to get a new rad cus i did that swap and your engine will get a little hotter now but i put a jdm rad in my car for my 95 civic and it runs a lot cooler now

 

hose clams will work but i did the swap in my 95 civic and it rad hot so i got a new jdm aluminum rad and my civic runs a lot cooler now then is did

 

^^ umm.. no. The B series still runs pretty damn cold. I don't know what you're talking about. If anything it seems to run a bit cooler than the D series for whatever reason.

You don't need a bigger radiator than stock. Just use some worm clamps to clamp the hose down to the D series radiator neck.

Using a bigger radiator is annoying in cold places because it takes EVEN LONGER for the stupid thing to warm up. Notice how Integras and EFs take like 15 years to warm up? F that. The radiator is too damn big on those cars. The half sized civic radiators work just fine for a NA B series. They're aluminum open deck NA motors. I've never had cooling issues with stock radiators and I'm not even a hard parker.

If I was a hard parker, I'd fake cooling issues so I could get some more bling under the hood that I was never going to use.

OP: Use either the 99-00 Si hose, the DC2/DB8 hose (not sure if the DA will work), or Del sol VTEC hose. Use a worm clamp for the radiator neck on your stock radiator. Done.

 

remember not to over tighten your radiator hose clamp because the radiator inlet and outlet are made of plastic. I swapped a B-series and I had over heating issues with my stock radiator. Then I swapped it with a fluidine and it runs cool now.
