You need to search or post in a different section. No one here is going to help you with your questions that have been answered over and over.

EDIT: In before the lock

 

Please tell us where u read u can put b17 pistons in a b20

 

HAHA^^

 

To answer your questions...

1. B20z is USDM from a crv. It is not from japan regardless of what your importer tells you. And the Intake manifold is bigger because it is meant for producing more torque for the CRV. No it will not fit under your hood...

2. Both LS and CRV injectors are 240cc. Depending on the ECU you run you might want to get slightly bigger injectors to avoid running lean.

3. On a B20 block there is two different OEM pistons: P3F and PHK. Your block has the higher compression PHK ones. If you would like to increase the compression in your engine you must look for aftermarket pistons at 84mm or bigger. The b17 pistons you mention are only 81mm and itll be like throwing a hotdog down a hallway on your slutted up B20.

4. There are plenty of options for aftermarket motor mounts, I reccommend new or replica OEM B18b or B20 motor mounts.

5. The B20 has two different heads, the head you have is identical to the LS. It will say P75 on it and you can swap them without any problems. The cams are the same as well.

6. Swaps are as hard as you make them, sit down and plan it out the right way before you buy the wrong parts (b17 pistons) and are left with the dead frankenstien.

Good luck

 

Who sayed his importer told him its from japan??

 

He just needs alittle guidance. Quite possible he's read somewhere about using "rs" spec p30 or b17 pistons that are 84mm. Although i've never heard of b17 spec pistons in 84mm size, its possible.

I believe for your build RS itr spec pistons would be ideal..
