Hi I would like to ask you about ls/vtec engines. Bassicly which of the 2.0 litres honda engines fit to do in them v-tec head from b16a2 ?? I will give some examples : b20b 128 hp/ b20z1 148 hp ?? Maybe some more ??Thx guys.

 

you can use any b18a/b or b20b/z block

 

Thx Man.

 

there is a b20b1 b20b2 b20b4 and a whole bunch of b20b's.

If its from america, the b20b is gonna have 8.8:1 CR, and make 126hp and 133ft lbs..

If its from Japan, the b20b could make 126hp, 142hp, or 146 hp.. and there really isn't any easy way to tell which one you are getting...

so that leads me to the b20z... which can be bought here in america.

It's guarenteed to have 146hp and 133ft lbs

So if you are looking to do a 2.0L vtec swap, go with a b20z.

If you are replacing your pistons anyways, then it doesn't matter which block because that is the only main difference

 

thx it's really a lot of help. I have found an engine but guy who is seeling it told me tha this engine is from japan. But on this name plate it has only b20 is it possible ??

 

if it's from japan I think it should say b20b, but it might just say b20... however there isn't any way for you to tell if thats the 126hp one, 142hp one, or 146hp one... and my bet is it's the 126hp one.

Ask him if it has a knock sensor
