I have a '78 200SX, which I bought new in '77 & she still runs great. Parts are getting harder to find, but you can go online to classicgarage.com and Tim can find almost anything mechanically that you need.
Check your electrical system, especially the trunk light. It is a 10-amp draw, & will kill new batteries in 24 hours or less. Just cut the wire & tape it up. I did this 15-years ago & haven't had a dead battery since.
Also check the circuit to the tail lights, if continually blowing fuses.
Good luck finding the problem.
I intend to keep mine until the wheels run square, since I still get 18-20 MPG back & forth to work, & 32.5 on trip from the San Francisco Bay Area to Reno 2 years ago in winter.
I just bought a 200SX (1978 too). It's awesome.
For parts, you might try searching on "cars.com" or other car sites and just buy cheap, old, non-working one. I have had the hardest time looking for something as insignificant as taillight cover (I hit a truck yesterday and busted my taillight. Gah, I am so stupid). Knowing me, a taillight won't be the only thing I'm gonna butcher... so, I'm just gonna nip this in the bud and buy a cheap car for parts. I suggest you do the same, since you seem to be looking for parts that are more important than my little taillight cover.
By the way, did you post a comment on this dude, Peter (?) 's "cardomain.com" page? That's funny (if it was you) because you seem almost as obsessed with finding sites related to 1978 200SX as me. Or finding someone that can tell you where to find parts, anyway.
Good luck with you car!
My first car was a 78 200sx. I was surprised myself, and won quite a few bottles of jack, and cases of beer dragging. Could be due to the weight ratio and the rear-wheel drive. The five speed on that car was awesome, I once even beat an 82 corvette. I'm currently looking for another car, as this was the car my wife and I had "relations" in the first time. Gonna take me awhile due to low budget, but I'm keeping my hopes up! P.S. by the luck of the car, will be married 20 years Valentine's day 2007!
Came across this site while looking for a 1977-79 200SX and was hoping anybody could help me find one to buy. I live in Cent. Fla, but would be willing to ship the right one here. Please contact me if anyone can help. Thanks!
I'm glad I stumbled on this site. I am a Datsun owner (81' 4x4 truck)...have had a long time. A neighbor of mine has had a 'parked' 200 sx for years. Every walk I make to our mail box, I glance at the car... wondering what they plan to do with it. Something has always told me that I would somehow end up with it. I recently heard a rumor of them thinking on selling it to our local junk yard. It still runs. Just needs TLC. I have already left a note on the car. It won't be hauled off if I have anything to do with it
I always thought the body style was a bit ugly... Bath tub style. But since I love all Datsuns, and thanks to comments on this site... I now know that the 200sx had some get-up and-go. I'm hoping to get it for $50-100...then spend months if need be getting it looking fresh again.
Thanks to the rest of you for the great comments. Chances are I will re-sale it if anyone is interested.
I have a 78 200SX as well. I'm the second owner from a guy that bought it in 77.
Not saying it's a good thing to do, but before I got my new clutch, I burnt up the rest of the old one sliding it fully sideways.
You guys are right, it's all about the power to weight ratio. Stock, I have beat the crap out of plenty of Hondas, and one I really remember is a 2nd body style RX7, and also a newer MR2. They are very quick getting up and going, but the tranny is built for acceleration, not top speed. But it's a very fun car to own. I will never, and I mean never, sell mine; it will get passed on to my son.
You can find me on ratsun.net if you want to know anything about these cars. I've torn mine down and put it back together almost fully. BTW mine's all original drive train, and when I bought it, my original stereo still worked.
