Well I actually got around to the compression test today. One cylinder is a bit low, but not too bad. 160-170-170-115psi (1-2-3-4). #4 defiantly has some issue but its not as bad as I was expecting.
I also got around to putting a new alternator in. The old one died and I decided to upgrade while I had to fix it. I got a good deal on a used Delco 7si alternator (out of a mercury marine boat) and it basically bolted in. I had to use a spacer on the rear tab but the pulley alignment was perfect! I still have yet to buy the proper connector for it, but it makes good power! 70 amp internally regulated and not much bigger than the 35 amp hitachi. If anyone is interested I'll do a full write up on the install, I took lots of pictures while I was doing it and I have the part numbers as well...
My main issues now are cooling (haven't done anything about that yet) and my transmission output shaft seal. I think I've decided to go the Sentra/Pulsar radiator method like is shown here: http://datsun1200.co...diator_Upgrades I just need to get around to calling some junkyards. Around here they close at about 1pm on Saturday and are not open Sundays, how they get any business is a mystery to me.
My transmission output shaft seal actually slid out of the transmission, I can push it in and pull it out by hand. This doesn't seem normal... I haven't decided if I'm going to try a new seal or just use some black silicone adhesive to keep it in there. If anybody has worked on this seal before, how tight should it fit?
It could use about 1" shorter belt
