b20b & z have the same stroke 89 mm as the ls but the b20b&z have an 84 mm bore b20b has slightly lower compression 8.8 and the b20z has 9.6:1 compression. a b20z is a bit harder to find though
for a swap into a teg you will need to find a new intake manifold because the b20 im is about 6-8" tall and probably wouldnt fit under the hood.
however if you have a b18b you could just use the im off that because the b20/b18b heads are identical.
