The 14” Chase Bays Tucked Radiator for Nissan 240sx Silvia S chassis & Skyline R32 is designed for those wanting to open up space in their crowded engine bays & get a better look aesthetically. This radiator is cooling upgrade, it offers more fluid capacity than stock, more direct airflow, & dual pass design. We shorten 8"of space. This radiator has been rigorously track/drift tested & is on countless show winning engine bays. 

We've designed this all aluminum radiator to fill every bit of space under core support while still being able to run (2) 12” fans if using our required shroud. This radiator requires some light front core support cutting. We wanted to make the radiator as large as possible while staying under core support. To accomplish this we had to cut into the chassis. This does NOT work with pop-up headlights since motors are in the way of where radiator sits. You can change to permanent up or do sleepy eye headlight / HID retrofit. 

Fans

We offer 2 different fans as an option. Although there are many factors in keeping a car properly cooled, we'll assume you have all your bases covered (good water pump, no leaks, sufficient wiring). It;s important that each fan is on its own relay w/ proper sized wiring & that fill point is actually the highest point in system. These 2 things are most commonly overlooked. For this reason we make
Dual Fan Relay Harness w. 180º F Thermoswitch that greatly simplifies wiring.

• Mishimoto 12" Fan  |  1,150 CFM each > 2,300 CFM total  |  $67.50 each
• Mishimoto Race Line HD Fan 12"  |  1,700 CFM each > 3,400 CFM total!!  |  $120 each (must use shroud since fans are powerful)

We see people using cylinder count as measurement for how powerful their fans need to be. We've learned this isn't best method for our overclocked engines. Its best to go by power rating. 400hp & under can use the less lesser powered fan, 401hp & over should use higher powered fans. However, this is only a 1 time purchase & we recommend going with higher powered ones no matter what. The Mishimoto Raceline Fans are 1.5 inch thicker than Mishimoto fans so they will take up more space. Luckily with this radiator you'll still have plenty of room. Install photos can be seen on photo scroll above, beige S chassis with SR20DET.

Modular Inlet/Outlet and Reversible Orientation
We've designed the radiator to be completely reversible w/ interchangeable inlet/outlet types. The radiator inlet & outlet have to be on same side since it's a dual pass design. Formerly when you purchased a radiator through us you'd have to select driver or passenger side. With new design radiator orientation is completely reversible. It looks the same on top & bottom plus brackets are centered.

Inlet & outlet are -20AN female threads. So we thread in whichever adapters you need. If you change your mind down the road, there's no cutting & welding. Just threading on new adapters. We offer OE style in 1.5" as well as -20AN. We recommend you put radiator orientation closer to upper water neck.  

We do NOT recommend -16AN for popular swapped engines & we give a fair warning about -20AN. Stock inner diameter of hose for SR/RB/KA/CA, 1JZ/2JZ, & GM LS engines is 1.5" inch. -16AN is 1" & -20AN is 1.25" By going w/ those, you're creating a restriction that's normally not there. -20AN is usually fine but -16AN you're reducing flow by 34%.

Dual Pass Design
This simply means coolant passes through TWO times instead of ONE. Which, more simply put means TWICE the cooling & half the size. Inlet & outlet are on same side of radiator & a plate is welded inside between the two inlets. Radiator has 2 L brackets on each side that you bolt to your core support. This radiator doesn't use any OEM radiator mounting points, & it's easier to install & un-install.

Fill Point

Since the top of our radiator sits about 8" to 12" lower than stock, we have to make a new fill point. 1st step is getting an inline filler neck, luckily you can now get that through us. The way you setup filler neck will make your hose selection easier. Our personal favorite is on radiator itself using our Chase Bays Raised Modular Filler Neck. We've attached a photo of this below.

To do this select -20AN for 1 side of Chase Bays Filler Neck when selecting options, other side will be whatever hoses you choose to go with. So if you're using OE Push-On style Silicone Hoses, you'd select "1.38mm Normal Hose" for 1 option & "-20AN" for other. -20AN side will thread right into radiator then you'll twist filler neck onto that. W/ thick O-Ring Seal on both sides, getting filler neck 0º vertical is easy w/ adjustment of both sides. 

The other option is putting it on upper water neck via clamp or welding (which will require fab work).
