that is good to know. ive been researching samurais and engine swaps for 2 months and that's the first ive heard of that.Where do you live? Will you have to pass emissions testing ?
The 1600 8 valve will add 15 hp. ( 80 hp )
BUT is prone to cracks in the crank case journals. Be careful when buying a used one. The 16 valve will net you 30 hp ( 95hp ) But requires a bunch of work. ( EFI )
We opted for the Datsun L 20B and drop pan 4 speed , 45 hp gain ( 110 hp )
Actually it was a much easier swap than the 16 valve due to the simple wiring.
And yes it will climb a hill at well over 75 miles an hour. ... Boxcar ...
