Alright i've been debating this for a while after reading up on the Z engine and it's 2 stroke diesel HCCI with a high swirl. I'm not so focused on the quick intake cycle to make it a 2 stroke but just the high swirl from the massive intake pressures. My main question is that if i were to beef up the engine to that of what you'd need to maintain 25 psi boost on a turbo would i be able to throw in 150 psi of intake pressure with a piston compressor on top of the turbo? I know the Z engine uses poppy ports on the side of the head to help with the piston rings from blowing all the time but since it's not a 2 stoke would that matter in my scenario? I'd like to have a main front mount intercooler for the piston compressor and just a little side mount for the turbo. My main goal is to get as high a CR as i can I'm talking 18:1. I just got to thinking about what would happen with 150 psi of force on the back of the intake valves, would that be alright?

 

are you referring to the honda z motorcycle engine? or the nissan z series motor? sorry im not really familiar with those, but what youre talking about is also a little above my head lol. Im honestly just curious because i learn about stuff all the time. also you mentioned diesel so im really lost.

ahh ok i got it. now ill throw in my 0.02 lol. is the question youre asking that of beefing up your current 4 cylinder in your accord? like applying the principles of the z engine into yours?

 

yea but only to use the certain principles.
