Pics of the fan setup?

[G-Man the Visionary]

Currently there isn't one, it won't fit. Trying to squeeze it in between AC condenser and radiator now. I did try moving the engine back some to no avail. Will keep working on it.

If you put the fan between your condenser and radiator your condenser will not work well. Plus it's a PITA to move because of the hardlines. Read the link in my sig to see how to mount a pusher fan.

Thanks, yes it is a pita, wasn't able to squeeze it in... If I can't fit it there though, it also won't fit between the engine and rad, probably because of the brand new firewall mat and no massaging. Thinking about just scrapping the AC system. El Paso temps are usually around 100 so AC would be great, but added heat from that plus the ambient temp and transmission wouldn't be good. I think if I lift the engine a couple inches it'll gain some clearance from the radiator and can pull it back enough to slide in the fan. Worth a shot.

I was running (2) spal pushers for a while - one in front of condensor, the other in front of radiator. I had to bend the tabs on the condensor to move it forward to fit the two fans in. I think the clearance was tight for the first one, though, as I went through two fans on the condensor as the blades hit something. It was a tight fit.

Now I have the stock condensor pusher and a small 8" spal puller on the radiator up in the corner. They are wired to both come on if either the A/C or temp sensor are triggered. Temp gauge is mid-way in stop-n-go traffic when "Houston hot" outside...

[G-Man the Visionary]

Cool, maybe I'll have to trade for an 8" and follow your lead... Why didn't you run the stock condenser fan at first?

Thanks to Corvallis, I got the sensor he recommended on his thread, hopefully that'll help kick on the fans early. Dreading the wiring of that stuff since it's not my forte.

[G-Man the Visionary]

Maybe a distributor delete would free up some space?

[CorvallisBMW]

It's a lot of effort for not a whole lot of space. You'll still have either your A/C compressor or water pump nipple to deal with, and probably only gain 1/2" or so.

I have a question based in the AT wiring. Did you have to do any wiring for the transmission? And what work would I be doing? I'm looking to do a m30 swap also and have everything I need I just don't know exactly what to do for the transmission aspect as far as wiring goes. Help me!!!!

[G-Man the Visionary]

You won't need any wiring if you use the transmission that comes with the e30... If you use the one with the m30 then you'll probably have an eh which requires all that mess. With the regular 4hp22 all you'll need is the right throttle body and a different kickdown cable. Oh, and the right bell housing.

Thanks, you're right... Just going to try to fab the mounts to sit a bit further... Exhaust is done, but haven't had time to go get it from the shop yet... Hopefully tomorrow...

So I can use my 325i auto transmission? If that's possible than that's what I'd like to do so I don't have to deal with all the wiring

[G-Man the Visionary]

Yes, but you'll need the m30 bellhousing. Be careful not to let it all fall apart when you remove bellhousings. Try standing it up on it's tail so gravity works with you.

[Ginger_e30]

Thanks

Thanks a lot man you've been a big help. Now I don't have to deal with wiring which I suck at lol
