I don't undersatnd how it could be "possibly" better than the 2j block? Without getting into details, the 2j block is just a 3.0 version of the 1j :1poke: .scottiedawg66 said:stock 1j block is as good possibly better than the stock 2j block due to having the same forged pistons, shorter forged rods, and similar crank. 40-50 psi stock block....i dunno bout that.

i think 86 bore x 76 or 72 stroke.. i dunno.. destroked 2jz
At lower boost levels, you won't see much of a difference between the two as your specific output is low...PM-Performance said:hmmm , I make the same exact HP as my friends 2JZ on the same turbo set up, but I actually make more TQ, I believe and I have a 1JZ.
All cases are not the same.
2JZ's are a little better IMO, but I dont think all that much , the displacement makes very little difference IMO
