Some specific questions about dropping the tranny? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi, I'm dropping the SR20DET trasmission by myself so I'm just going by the research I do on the web. I have a few specific questions though that I don't know the answers to.

So far I've got the driveshaft off, tranny fluid out, shifter out, downpipe off, slave cylinder off.

Here are the questions:
#1 The starter motor - where are the bolts located for this? The front of the bellhousing or will it be on the motor side? What do I have to disconnect from the starter? (I have the battery disconnected, btw).

#2 All of the harnesses that need to be unplugged will be using snap connectors or are there some other ones as well?

#3 The bellhousing bolts, how do I get the top ones out? Do I take the tranny support out to lean the motor down first to do this? I have some 3/8" extension bars which are like 3ft long. I am going to be doing this myself so I'm gonna probably prop the tranny up on a motorcycle lift instead of a jack because of the larger area. (Sorry, this question may be intuitive but none of the tutorials tell how to do this, they just say to pull it off and that's it).

#4 Are there any tricks to lining the transmission back up when putting it on? I'm just going to be pulling it back to replace a busted pivot ball.

Some miscellaneous stuff when putting it back together:
#1 How hard do you need to tighten the drive shaft nuts when putting it on? Like finger tight, finger tight + like 90 degrees more, or "hard as fuck"?'
#2 The heatshield off the down pipe is pretty mangled (in terms of the shielding material inside which is flaking). Do I need the heat shield anyway? The thing just rattles anyway.

Thanks for any help.
