For the archives, I just replaced my 240z blower motor with a 91 acura integra one. It is a direct bolt in besides the wiring and also has a plastic cage.

This body style integra was produced from 90-93 so it is safe to say any blower motor from those years will be a direct drop in. I would also think that 90% of all honda/acura blower motors will drop right in.

I apologize for sounding like a noob, but are you talking about Heater Blower Motors?

Yep. Got one in my Z Mat, so you've actually used it before. The stock fan is pretty anemic. I got mine from a Mid 80's Integra, then I broke the squirrel cage part being a dumbass so I went back and got one from a 88 (?) Civic. Plugs right in, just need to make 2 little jumper cables to connect the Honda wires to the Datsun wires. There is a guy on ebay selling them for $80, I got mine from the junkyard for $10 each.

I understand there is a bit of modification that needs to be done on a 280. Here's a link for those interested: http://forums.hybridz.org/showthread.php?t=83234
