turbo 5 intercooler routing
here's my setup for anybody curious. i'll be running a turbo blanket to minimize the heat soaking. as this is not a race or drag car, just a humble street built 617, i couldn't be pissed to do an air to water.
he221w (can use stock turbo clocked upwards with a 90° elbow)
the he221 goes up to a 2.5 at the mouth of the elbow so you'll need a 2.5-2.25 reducer to fit it to the intercooler inlet
renault turbo 5 intercooler with 2.25" inlet and outlet. tilt backwards so the flanges are level
2.25 aluminum 90° elbow. if you run my setup, you'll be cutting a little bit off the intercooler end to make sure your elbow clears the inner wheel well and shock tower. it should meet at the manifold dead center between the first pair of exhaust runners.
i had a shop plug, cut, and weld a new flange off the intake manifold due to my lack of aluminum welding equipment.
i think with an original 300d with an expansion tank, this'll clear the tank and the coolant hose to the radiator but you'll have to bypass one of the aux water pumps. this is a 240 swapped with 300d parts so i had the expansion tank mounted more forwards. it needed to move regardless.
