If I bought a Nissan Homer 1973 Are part,s still available and how
Much would it cost to rebuild the motor?
Some body has one for sale $1000 I think its a bit to much$.

Parts are still available. It will cost you $800-2000 to rebuild the motor. Depending on the rebuild.

From memory I think the pre 72 model had the "R" series engine. Yours would have the "J"series engine in it. I had one on the farm about 15 years ago and put a holden 186 in it. Much better than the J.

The one I am looking at has really low compression in number 2cyclinder the guy
said so that sound bad to me

So just get a good used J15 out of a Datsun 620. You might have to swap manifolds or oil pans, but these engines are not rare.

The guy wants $1000 unregisted I think it could be cheaper

I think they are only rated at 1 ton so a navara or old hilux would be better.

$1000 for one of those seems a lot of money for one of these.

Yeah I think so to The only reason I would buy would to turn into a camper
for travel

Would make a pretty wicked jap version of an old race car hauler, but at one ton carrying capacity you'd kinda be sticks with a 1000 and your tools and tyres

They are that friggin slow you would be able to take in a lot of scenery .
I think I would rather buy a tent.
