hey i have the chance of buying a h22a4 block for cheap , but running a h22a1 motor. Just woundering if i build up the h22a4 block for turbo , would i run into any problems mating it with the h22a1 head after i get it back? Thanks if anyone can pls help me with my prob plz.

 

nope,the h22a4 block has one advantage and that is it uses bigger mains on the crank.Using an earlier h22a head is not a problem.

 

Just remember to you the h22a4 headgasket or you will have problems!

 

so if i use the h22a4 would i end up with more torque ? just a ? imma newbie
