1. When in fifth gear and driving about 70mph on the freeway after awhile sometimes it will pop out of gear. Like when I'm driving it slips out of 5th gear position and into neutral. Why is that?

2.It kind of lags on acceleration- just did a ZC swap and when I'm on a hill and i take off in first gear it lags like it doesn't want to go then the gas kicks in and it takes off. Why is that? Sometimes on level streets too.

3.Alternator belt squeals, I know this is cause the belt is loose but it tried putting the crx 91 stock belt on it and it was too big which belt should i use for a Single Cam ZC swap non-vtech

Thanks in Advance to whoever helps me out with this =]

 

the tranny problem sounds like syncros the belt i went with one 2 sizes smaller on my b16 swap and now on to question 2 it sounds like low fuel pressure
