SpeedFactory Tucked Radiator Dual Backdoor Intercooler

SpeedFactory Racing Dual Backdoor Intercooler and Tucked Radiator Combo - Part #SF-06-100

A big front mount and a tucked radiator are the two parts that fight for the same six inches in front of a turbo B-series or K-series Honda. Buy them separately and you spend a weekend making them live together. The SpeedFactory Racing Dual Backdoor Intercooler and Tucked Radiator Combo is the two parts already stacked, mounted, and fanned as one assembly so the front of your EG, EK, or DC2 comes together in one shot.

What It Is and Why It Works

The intercooler is SpeedFactory's Dual Backdoor core. Standard is a 24 by 12 by 3 inch bar and plate core rated for 600 to 850 plus horsepower; the HP version runs a 3.5 inch thick core for builds heading toward 1000. Both use hand-formed 5052 aluminum end tanks, TIG welded, with the 3 inch inlet and outlet exiting out the back of the tanks. That backdoor layout is the whole point. Your charge pipes run straight to the throttle body and turbo instead of wrapping around the front of the core, which means shorter pipes, fewer couplers, and piping that clears the crank pulley on a tight EG or EK front end.

The radiator is SpeedFactory's aluminum tucked unit, a dual pass, dual core crossflow that sits under the core support instead of in front of the engine. SpeedFactory quotes coolant temperature drops of 20 to 30 degrees over a stock radiator. It comes with a 7.5 inch 458 CFM puller fan and your choice of -16AN or 32 mm hose end connections. Pick the B D F H-Series or K J-Series version so the outlets land on the correct side for your engine. The whole assembly is 32.5 inches wide, 12 tall, and 8.5 inches thick in Standard form, 9 inches in HP form.

Fitment

SpeedFactory states this fits most Honda and Acura chassis with modification. On an EG, EK, DC2, EP3, or DC5 plan on trimming the bumper support and fabricating brackets. The overall width of 32.5 inches, not the 24 inch core, is what has to clear your frame rails. Pick the B D F H or K J radiator option to match your engine's outlet locations.

What to Know Before You Buy

This is a universal assembly, not a bolt-in kit for one chassis. Measure your frame rails before you order. The 32.5 inch overall width is the number that matters, and on any Civic or Integra you will be trimming the bumper support and building brackets to the welded M8 bungs. SpeedFactory's own page says to call before ordering for current lead times, and these ship as built-to-order pieces.

Pick the intercooler by the power you're actually going to make, not the number you hope for. The Standard core covers the overwhelming majority of B and K turbo street and drag cars. Step to HP only if you're really headed into four-digit territory, because the thicker core adds half an inch of depth you have to find. Choose the radiator connection by the hose kit you plan to run; SpeedFactory sells matching -16AN hose and fitting kits, and the 32 mm hose end version takes conventional silicone hose and clamps. If you want Vanjen flanges welded on for quick-release charge pipes, that has to be arranged with SpeedFactory before the order is placed. And sort your fan shrouding and ducting while the front end is apart. A thick front mount sitting in front of a tucked radiator will push coolant temps up if airflow through the radiator is an afterthought.
