Before I get flamed to death, I'd like to start off by saying I'm foreign

so my lack of information is understandable.
That being said.. I just bought a 1980 Datsun Sedan, I've been looking for information on it for the past 2 days and I'm getting awfully sick of coming up with porn. Well not /really/ but it's tiring to not be able to find much information on this cool little car.
I've done a few searches on Stanza, L16, A10 etc. and havn't come up with a whole lot of helpful information.
I was curious if anyone knew of any Stanza clubs, or any good websites I could check out to learn as much as possible about this car..
I'm looking for some information on power, suspension, body and interior mods that can help me with my addiction to modifying things..
So far I've seen articles on L16 blocks with 510 SSS heads on 'em, some turbo/supercharged L18/20's, bluebird front ends on the same model stanza as mine (I believe turbophile has a blue stanza..or it's here, I forget.)
I'm looking at just a decent all around upgrades I could do, but the only cars I've owned previously have all been fuel injected, so I'm pretty new at carbureted systems..
Now.. on with my goals with this car - just to get some feedback on what people think..
I was thinking about throwing on some nicer rims and tires, something from another Nissan/Datsun that looks a little nicer then the stock steel things on there now. The tires are new so I don't want to replace those as of yet - but I'd like to make it a little better to handle, so when tires are required I'll have to go with something better then whats on there now.
Theres a dent in the front bumper - so I was thinking, after seeing that bluebird bumper on the other stanza, it might be worth doing something like that, instead of finding a nice condition stanza bumper, as I don't think it can be repaired. I'll have to see later. I really liked the look of that bluebird bumper but I don't know how much of a bolt on that would be, and I'm not good at fiberglassing so I'm a little weary of hacking something up.
The fuel guage doesn't work in the car, and the speedometer is sort've hard to see - I'm used to much larger.. but I think the style of this speedo is rather cool - and would like to perhaps make it better, somehow. A tach would be nice as well, although not necessary I'd still rather prefer one.. so a custom dash with a few new guages might be an idea - although the dash is uncracked and in very, very good condition so I don't want to wreck it if i don't have to.
The seats are comfortable - but there are some tears in them here and there, wouldn't mind replacing them with something a little more modern.. not racing seats as it isn't exactly a race car (all 80 hp of it) so I don't want to have something not needed..
I'm not sure what sort've work I can do on this engine to make it perform better.. It has 68,000 km's on it, everything was replaced a few months ago so I don't want to do an engine swap yet - if theres a decent list of power mods I can do to give it some extra kick, such as less restrictive exhaust - bigger carb - better filters.. I don't know what sort've options I have with this engine as like I said - I'm inexperienced with it.
I'm not looking for a rally racer or a drag star.. Just looking for a reliable daily commuter that looks neat and goes well.
If anybody has any information regarding Stanza's - or wants to drop some suggestions here and there, please feel free to. Sorry for being such a newbie and posting a new thread when I could've searched for a few hours and found it all - but I thought someone around here might have a few links I ought to look at before wasting time.
I'll get some pic of the car on Friday, wouldn't mind hearing peoples suggestions on what can or should be done to this car.
Thanks.

Sorry about the novel - didn't want to do multiple posts when it could all be thrown into one post.
