if one choose to turbo a bone stock jdm itr 11:1 compression, what should be upgraded to allow more hp/boost without blowing or melting **** up?

so far, only thing i can think of to help make the block stronger is forged rods and pistons with coating on the piston.

what else is the weak point on the high compression R?

 

tuning, tuning, tuning.

Here is a good thread. 11.5:1 compression turbo build:
