The mishimoto heat exchanger fits well, just have to fabricate some brackets and replace the quick release nipples with AN bungs.

this is a heat exchanger from a previous build, it fits exactly between the frame rails and under the radiator like the stock intercooler did so I’ll be using it as an auxiliary cooler along with the Mish.

Is that an S55 valve cover? What all was involved in retrofitting it to the N54? Are you running standard height radiator, same size a2w heat exchanger, and then the new cooler below those to take up the oe intercooler space? Still using N54 oe radiator fan?

No it’s the original N55 one as this is an M235, I have not fabbed any brackets yet to support the weight of the intercooler, it’s being supported by the inlet and outlet pipes and some cardboard I used as a spacer at the intake manifold. I am using a standard height engine radiator but the upgrade one from CSR and the heat exchanger is the upgraded one from Mushi. for the M2,3,4. The second cooler below the radiator is a generic eBay item ( frozen boost I think) measuring 26x7x 3.5”, it’s fits flush with the back of the radiator and front of the condenser so yes the OEM fan is being retained.

The blue covering is the protective cover csr uses on their products so you can see the fitment is perfect.

The Mishi installed in front of the entire cooling stack just like the M2,3,4 cars. It fits well but I did flatten the sections of the brace directly close to the tanks to ensure no contact to cause future problems, it will be powder coated with the rest of items when I’m done.
