From what I found on search, the F20b blocks dont have the same reinforced cylinder walls as the H22's. Reason being, I was thinking the block would be able to hold greater PSI with a turbo.

With that said:
- Would a F20b block fit with a H22a head?
- As well as a H22 LSD tranny?

Also found in research, some mentioned boring out the block and putting in RSX pistons. Would they be worth it or should one go with an aftermarket piston set?

With all that said, my plans were to have a boosted motor (f20b block, h22a head, h22a lsd tranny).

Any info is appreciated!

 

Yes it will work, the f20b and h22a heads are nearly the same....and all h/f transmissions are interchangeable with the exception of only the SH preludes and the f20c (s2000)

Use forged pistons if you're going to boost the car.

 

dont you like f20b head??

and some people said that, B20B pistons would fit.... im not sure though..

 

actually FRM sleeves are stronger then Iron liner sleeves in the other honda blocks the problem is you can't run regular forged piston but yeah you can use h22 tranny but your problem is finding forged rods and piston for the f20b since i don't know any company that makes them so you might have to go custom.
