well my buddy has a 93 civic 4-door automatic and we just installed a home-made turbo kit, he is running about 5 psi, we installed an SMIC and everything seems so be running fine, we did replace the headgasket with a new one and changed the oil and little things like that. his motor is a d16 block and a d15 head totally stock,
is 5psi alright with stock internals?
would you suggest getting an fmu or s-afc?
let me know
thanks
