b20 difference
If im doing a b20 vtec, should i get a
1) USDM older 96 crv b20 2) JDM any year b20 3) 99-00 USDM b20 Z also, whats teh diffrence in blocks between a b20z and a jdm b20 .... |
get a b20z....it has the phk pistons (higher compression)
The only difference between the two is the pistons....the b20b is like 8.8:1 CR and the b20z is 9.6:1 CR (or around there). |
Like Andrew said, you could go with B20z block. The CR goes from 8.8, to 9.2, to 9.6.
But if you are going to rebuild the entire long block, then the pistons don't matter much. |
and there's a few b20s that only came in certain cars that has a P8R head in jdm land. this head has intake valves the same size as the vtec heads but it's very rare. i don't know how much of a difference it makes but just letting you know.

The B20 (87-91) from the prelude is not to be comfused with the newer B20. They are a different family of engines and are not compatable whatsoever.
