Description

The 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, geta better look aesthetically, and improvecooling power. It offers more fluid capacity than most aftermarket rads, more direct airflow,& dual pass design. We shorten 8″ of space but increase the width and thickness to compensate. This radiator has been rigorouslytrack/drift tested for nearly a decade & is on countless show winning engine bays.

We’ve designed this aluminum radiator to fill every bit of space under core support while still being able to run (2) 12 fans. This radiator requires some lightfront 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 radiator hits the stock S13 pop-up motors, butwith this product it can be relocated:S13 Headlight Motor Relocation

Shroud?
We formerly sold our Radiator with a Fan Shroud, until June 2019. This was a great way to mount fans (Mounting fans directly to corewill void your warranty and ruin the Radiator) and to increase cooling efficiency. The only problem is anything past 12mph…ashroud can actually restrict flow.We changed to fan brackets built intothe radiator and no complete covering shroud. This decreased the price $175 dollars AND increased cooling efficiency. =O

Fans
The radiator is setup for ourextremely high powered 12″Chase Bays UltraDuty Fansthat are1,700 CFM each. 3,400 CFM total!! It’simportant that each fan is on its own relayw/ proper sized wiring& that fill point is actually the highest point in system. These 2 things are most commonly overlooked.For this reason we makeDual Fan Relay Harness w/ 180 F Thermoswitchand ourRaised Inline Filler Neck(read more below).

The Chase Bays Ultra DutyFans are 1.5 inches thicker than standard Slim Fansfans so they will take up more space. Luckily with this radiator you’ll still have plenty of room on i6 and V8. Install photos can be seen on photo scroll abovewith all engine types.

Modular Inlet/Outlet and Reversible Orientation
The radiator inlet& outlet have to be on same side since it’s a dual pass design. We’ve designed the radiator to be completely reversiblew/interchangeable inlet/outlet types.It looks the same on top& bottom plus the 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 1.38″ and 1.5″, -16AN, and-20AN. We recommend youput radiator orientation closer to upper water neck. On JZ’s, we cut and mod the upper neckto NOT face the LHD Driver Side.

KA/SR Upper& Lower: 1.38″(35mm)
RB Upper: 1.38″(35mm)& Lower: 1.5″ (38mm)
1JZ/2JZ Upper: 1.38″(35mm)& Lower: 1.5″ (38mm)
GM LS Upper & Lower: 1.5″ (38mm)

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 1.38″ and 1.5″ inch. -16AN is 1″& -20AN is 1.25″ By goingw/ those, you’re creating a restriction that’s normally not there. -20AN is fine but -16AN you’re reducing flow by upto 34%.

Fill Point
Since the top of our radiator sits lower than stock, we have to make a new fill point. 1ststep is getting an inline filler neck, luckily you can now get that through us.The way you setup filler neck willmake your hose selection easier. Our personal favorite is onradiator itself using ourChase BaysRaised Modular Filler Neck.It’s raised perfect height to match original fill point height.

To do this select -20AN for 1side of Chase Bays Filler Neck when selecting options,other side will be whatever hoses you choose to go with. So if you’reusing OE Push-On style Silicone Hoses, you’d select “1.38mm Normal Hose” for1 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 0 vertical is easyw/ adjustment of both sides.

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

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& the end tank is made as two completely separate rectangle cube pieces to block flow between upper and lower. Radiator has2 L brackets on each side that you bolt to your core support. This radiator doesn’t use any OEM radiator mounting points.

Hoses
Factory hoses don’t work. We piece together silicone hose bends w/ small joining couplers & use Gates Heat Shrink Clamps for a seamless install. We’ve been drifting our E36 non stop w/ no issues with this.Click here to set your hoses up.

Pressure Tested
Each radiator is pressure tested to 30psi. Your radiator shouldnt see more than 16-19psi before radiator cap spring does its job& expands into overflow.

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’simportant that each fan is on its own relayw/ 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/ 180 F Thermoswitchand our Raised Inline Filler Neck (read more below).

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

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 &undercan use the less lesser powered fan, 401hp& over should use higher powered fans. However, this is only a1 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 on i6 and V8.
