240Z: “Honda” Blower upgrade Motor

One popular upgrade for the 240Z seems to be swapping out the lame Original Heater blower motor to the one coming from some 80ies or 90ies Honda. Unfortunately all the manuals i found for this swap mentioned a different Honda model as source for the Blower motor so i was confused. They all looked the same in the pictures and some guys on Ebay even sell the Blower swap for around 90$ + shipping. I thought that’s too expensive and did some research and figured out the one blower everyone is using is the TYC Genera Model 700077 which is an aftermarket replacement for the aforementioned old honda motors. Funnly this blower is sold for only 23 Bucks so i went the direct route and ordered it 🙂 This is the old Nihon Radiator / Hitachi Blower:

And here we have the new one. Brand new and factory fresh 🙂

As you can see the shape is slightly different (left new, right old), but it wil fit perfectly.

I compared with the drawing on the TYC website and many people in the internet told this is a 1:1 swap except for the rubber gromments which need to be changed due to different mounting hole diameters (other people probably will enlarge the holes). Also i recommand to paint the now Silver motor cover black as this is installed right in the foot compartment of the passenger and will stick to the passengers eye 😉

According to the poeple in various forums the advantage of the new Blower is: Much more powerful, much more silent, lighter (Due to the plastic squirre-cage compared to the metal one in the old design) and draws less current. Overall it’s much more effective. can’t wait to install it. Of course i will write about it once i get to that point 😉

Update: It seems like you need to swap the wires since it’s turning in the opposite direction factory-wise. but that’s not a big thing.
