Im building LSVTEC Im going to have sleeves and forged pistons and rods so i need to know what compression to use for reliability and power i have 3g hondata and a 57trim turbo with .63 ar please help

 

9-1

 

i was told to get 9.8:1 or 10:1 more compression less boost more power

 

how much boost do you plan on running,how well built is your lower end going to be,and what is your engine management???

 

im going to fully build the bottom end with sleeves forged pistons and rods and all the bells and whistles i want to be able to run 25 psi on race fuel i have hondata stage 3B and RC 550 injectors it is externally gated

 

again 9-1,I am running 23psi c-16 fuel,zdyne ecu on a fully built d16a1(88teg)trust me you won't be dissapointed

 

9:8:1 CP pistons here

FYI, You are gonna need more than 550's for 25psi on a built LS VTEC.

 

700-800 cc injectors would do ya.

550's wont cut it without a ton of base pressure and even then i don't think they'll flow it.

 

9:1 here on my ls vtec

 

9:1

 

9.8:1 here

 

cp 9:1
