Blower Motor Upgrade (Kia Sportage)

Recommended Posts

I spent several days researching ways to improve the air output on my 76 280z and wasn't able to find a really nice walk through, so I thought I'd share what I did. It looks like most of the people who put 1988-1991 Honda Civic blowers in their Z weren't able to feel a big difference. I noticed some people also suggesting using 1993-2004 Kia Sportage blowers. So, off to my junk yard I went. I found both a Civic and Sportage blower. After comparing the two, the Kia blower seemed better built and had a larger cage so I bought it for $30 and proceeded to my Z.

 

The nice thing about this upgrade is that the Kia blower is roughly the same size, it rotates the correct way, it uses the same wire harness, and it uses the same mounting holes.

 

It just so happens that I have taken my dash out to install a dash cap and add LED instrument lights. I don't know if you could do this upgrade with the dash in place because the entire blower housing has to be removed.

This is the guide I followed for removing my dash (PITA!)

Here is the blower housing location

The original blower and cage are on the left. The Kia unit is on the right

I removed the foam padding from the fan housing since the kia unit doesn't need the extra spacing.

Next, I placed the Kia blower cage over the hole, lining up the bolt holes, and marked the area to widen. I highlighted this in red.

Using some aviation snips, I cut out the excess metal. I cleaned up the hole with my Dremel later.

I then placed the new Kia unit in the blower housing and secured it using the original bolts and washers.

The unit spins free and has just enough clearance

 

The original Z wire harness fits right into the new motor. I plugged it in to make sure it works and it really seems to put out some air. I'll post another update once I get the dash back in.

Oh man, the leaves....so many leaves.

Working on this has kinda given me a bug to do something drastic. I'm looking at all these vacuum actuators and wondering what it might take to remove the entire vacuum system from the HVAC and replace it with an Arduino digital controlled system. Here is a mockup I did using the Tesla interface on an extra tablet I have laying around. I think I have the skills/friends to make this work, but I'm not sure if this might be a bit....much?

I'm studying up on the FSM right now trying to figure out the different actuator and water cock positions for different settings. 

 

What do you guys think?

Before I went with vintage air I thought about doing this. Went to the junkyard and there were 5 or 6 sportages there. 1 was missing the blower and all the rest were bad. You may want to grab an extra motor since it appears they have a high failure rate.

Ya.  Mine originally came from a pick-n-pull because I was there to "do the Honda blower swap".  That's when I discovered the Kia blower.  (I actually looked at every import in that yard because I thought the Honda blower looked kind of wimpy...)  Mine has worked great lo these many years - but now that I know, I'd just buy a new one rather than go back to the junk yard...

You can get a new one for around $40, but they don't come with the cage. The first Sportage blower I pulled was defective. Just make sure that the motor spins freely or bring a small 12v battery.

 

I put the dash back in the car this weekend and the blower does indeed put out much more air. It'll be put to its true test this summer :)

Sounds like a great idea.  I was looking to do the same thing.  Converting to servo operation and using modern controls from a 350Z.

No.  The 280ZX blower (and all other Nissans from then on) spin the opposite direction. The blower box is different due to the rotation.  Nearly every other model import also.  That was my conundrum while I was grazing thru the Pick-A-Part...  The only blowers I found that were similar size and set up to spin the same direction as an early Z were the Honda Civic and the Kia...

That's awesome. I'm definitely ordering one! Can you pull the blower box out without taking out the whole dash?Also is it true you can feel air coming out when the fan is on low speed?! :D

 

You might be able to do it without removing the dash, but it would be a real PITA to get to some of the bolts. You might want to try loosening the dash bolts so you could at least move it a bit.

 

And yes, I can feel some air at low speed :) I wish my A/C was charged so I could actually cool off.

My car has factory A/C. I'm pretty sure everyone in this thread does as well. I guess I don't understand the rest of your question... The Kia blower is essentially the same as the stock blower. It has a slightly larger squirrel cage with more vanes and moves more air

Everytime this topic rises to the top I forget I'm looking at the Interior forum and I get all excited about somebody putting a blower on their motor, like a Maggie, Wipple or Paxton.  Someday I will get the HVAC system back into my car...its been at least 15 years, and it would be kinda nice.  Y'all interior folks, have fun!  Happy New Year!
