Hello Ratsun!!
I'm new to this site and this is my first post. So here's the story on my datsun..
I have a 1981 King Cab 4x4 i picked up two years ago from my great uncle who passed away at the time. It is a two owner (including myself) truck that my uncle drove off the showroom floor in 81 and kept pretty damn good care of. It's got 185,000, 7,000 of which i have put on. I even have the original owners manual from the factory and all of his oil change reciepts.. Since i've owned i've done all the usual old truck tuneup stuff like new plugs and wires, distributor, belts, etc.. but other than that have kept it entirely stock.
Now however I want to do some work on it. Nothing major or crazy, but i do want to get some more power out of the engine, not a whole lot, just enough so that it isn't a complete dog anymore..The engine is a z22 by the way. I also plan on putting some bigger and more aggressive tires on it as the ones it has are wee bit dorky...
Anyway here's a couple of questions I have..As far as adding some horse power goes it seems the way im headed is getting a new carb and at least cat back exhaust at 2'..What sort of carb would I want to be looking at for my z22 engine? Also by adding a bigger carb will i need to replace any internal parts on the engine as it's so old? I dont know a whole lot about engines but have a mechanic who will be helping me work on the engine..RReally any suggestions about what I could do to get more power would be helpful.
Well I'm sure there will be more questions as I think of them, but for now farewell and thanks!
