Phantom Posted June 2, 2003 Share Posted June 2, 2003 I have a '77 280Z and the fan for the Ac is way too underpowered. I have new everything in my AC system and can get the air cold but just can't move enough of it to cool the car down in this Texas heat. Anyone know of a drop-in blower that will move more air - like twice as much?? Quote Link to comment Share on other sites More sharing options...
DavyZ Posted June 3, 2003 Share Posted June 3, 2003 The Civic unit (motor and squirrel cage) is supposed to work and be a practical bolt-in--do a search bubba There are some good threads about this very topic. Pete Paraska used one from a Lincoln (?) and it blows serious air, but it requires some "cobbling" as he put it. Hope this gives you some ideas. Say, you are talking about the fan motor, yes?

Phantom Posted June 11, 2003 Author Share Posted June 11, 2003 Did a search & came up empty. I'll keep the civic in mind. Thanks Quote Link to comment Share on other sites More sharing options...
niceguy678us Posted June 11, 2003 Share Posted June 11, 2003 I hope someone answers this one about the lincoln motor. I want to know more. THE SEARCH FUNCTION IS OUT AGAIN!!!!!!!!!! I want the cold air to rearrange my hair when turned on, if you know what I mean. Quote Link to comment Share on other sites More sharing options...
Dave Posted June 11, 2003 Share Posted June 11, 2003 Heater blower motor and squirl cage from a 88 HONDA Civic CRX is a direct bolt in swap and works well. Quote Link to comment Share on other sites More sharing options...
Phantom Posted June 11, 2003 Author Share Posted June 11, 2003 Dave, By works well do you mean it blows as much air as the stock Datsun blower - or a lot more? Is it a 4-spd blower too? Quote Link to comment Share on other sites More sharing options...
timh Posted June 11, 2003 Share Posted June 11, 2003 Does the CRX blower work well compared to a 240 blower, or a 280 blower, or both? I think Pete's was from an LTD. Quote Link to comment Share on other sites More sharing options...
Dave Posted June 11, 2003 Share Posted June 11, 2003 I have a 71 240 and a 75 280 AC car, the 71 has the Civic blower in it and it whips up a storm compared to the 75 that has the stock AC. The civic blower is one wire but has the speeds controlled by the blower switch that must have resistors for the different speeds. Here is a link to info on both the Civic and Ford heater blowers. http://www.zcar.com/forums/search.php?f=1&search=civic+blower&globalsearch=1&match=1&date=0&fldsubject=1&fldbody=1 Quote Link to comment Share on other sites More sharing options...
timh Posted June 24, 2003 Share Posted June 24, 2003 I installed the Civic (any civic between '87-'91) blower last night. It doesn't just slide right in, took about 6 dremel cutting wheels and 30 minutes to open the diameter of the housing enough to fit the larger diameter squirrel cage. After that it was easy. IMO it's a moderate improvement over the 280z blower, and would be a vast improvement over the 240z blower. One thing that I noticed while I had the glove box liner out was the large gap (up to 1/2") between the center vent section and the evap box, where the foam seal was missing. I replaced that and several other foam seals on the ducts. The down side is, my glove box is no longer a make-shift refrigerator. Take a look at these items when you tear in to your system. Now I have to figure out what I did to make my A/C fuse blow and my radiator fan stop working. sux Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted November 20, 2004 Share Posted November 20, 2004 has anyone taken photos of the crx/civic blower swap? I have found these photos of the 88-91 blower, I assume the colour doesnt matter or does it inicate a different model Thanks Quote Link to comment Share on other sites More sharing options...
Guest swanZ Posted September 16, 2005 Share Posted September 16, 2005 Battling through the complete rebuild of the heating system (frozen heater valve, frozen cables, nothing pretty much works). I figured that I would throw in the Civic blower when all was apart. Seems to fit perfectly! One thing, it has two "+" terminals on it? One points to the left and one to the right - ? Do I just pick one and ground the unit? I have a 1973 240Z and it came with air (purchased this year). Could that be stock? Did they have it that year? It has a York condensor, and there is a large unit underneath the glove box. The belt is missing, so I have no idea if it works or it is worth fixing. I figured I would start with heat and go from there.... Quote Link to comment Share on other sites More sharing options...
qwik240z Posted September 16, 2005 Share Posted September 16, 2005 Bill, Here is one on eBay like the one I bought. It says minor trimming is needed for 280Z but bolt in for 240Z. I bench tested mine and it moves way more air then the 240 unit. [http://tinyurl.com/94g63] Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted September 19, 2005 Share Posted September 19, 2005 Installation photos would be excellent and answer many future questions if someone has the time. Quote Link to comment Share on other sites More sharing options...
Phantom Posted October 6, 2005 Author Share Posted October 6, 2005 David, Have you had a chance to install the blower yet? If so: 1) What specifically did you have to do to install it? 2) What is your impression of the amount of air it moves? 3) Were you able to maintain the 4-speed function of the stock AC lever? I'm still using the one that came with the car (28 years old now) and it is good for up to about 100 degrees. After that the whole system just gets overwhelmed. It used to only be good to about 90 degrees but it is amazing what 100 lbs of insulation in a car can do. Quote Link to comment Share on other sites More sharing options...

Phantom Posted October 6, 2005 Author Share Posted October 6, 2005 Let us know all the gory details when you do. This might finally resolve one of the big concerns with the Gen 1 Z's! Quote Link to comment Share on other sites More sharing options...
big-phil Posted October 6, 2005 Share Posted October 6, 2005 Phantom, I also have trouble in the Texas heat, My blower blows fuses?? I went through 2-3 this summer. Has anyone else had this happen? Quote Link to comment Share on other sites More sharing options...
Phantom Posted October 6, 2005 Author Share Posted October 6, 2005 Big-Phil - Fuse problem is probably related to a binding problem or the motor in the blower going bad. I've never had mine blow in the 13 years I've had the car. It's not the heat - it's something with the blower. Quote Link to comment Share on other sites More sharing options...
74Adam Posted October 7, 2005 Share Posted October 7, 2005 I just got one of those on ebay as well for my 78. Hasn't come in yet. I just got this 78 a couple of weeks ago and this is the first time I have had a driveable Z in several years. Anyway, I had forgotten how much heat comes through the tranny tunnel. Phantom, I noticed you had put down insulation, I was about to mention that being the first thing to do. On my current A/C, the air is actually pretty cold, just not enough of it. When I put this new unit in I will check for gaps in the seals and then I will report back the results since some might be curious how much of an upgrade it provides in the 280. One issue I am very curious about however is with the greater volume of air will it still be as COLD? Qwik240z, what have you observed regarding this? -Adam Quote Link to comment Share on other sites More sharing options...
Phantom Posted October 7, 2005 Author Share Posted October 7, 2005 Adam, If you're getting a lot of heat coming up around the gearshift lever then the tunnel seal is either missing or torn. It's amazing how much heat that seal keeps out. A new seal along with a little insulation on the tunnel goes a long way to keeping the car cooler. Another area that can really help is an addtional 1/4" of insulation above the headliner. The roof is a real radiator too. Third area is the firewall. Make sure all the penetrations are sealed. If you do all that you'll get another 5 -10 degrees worth of outside temperature that your AC can handle. Quote Link to comment Share on other sites More sharing options...
