Default Rod/Stroke ratio + Comp

hey ppl

just need a little help here, ive searched but cant find any answers, or an r/s ratop calculator,

basically i need to know if this is reliable or not.. or what are my alternatives,

b16a Head
ITR Block
ITR 81.25 pistons
ITR Con Rods
89MM crower Crank

Could someone tell me what the R/s ratio will be ? also weather this will be safe and any alternatives (baring in mind i cant use after market pistons because i aint got them or after market rods) however, b16 rods are avalible, aswell aswell ctr pistons and b16 pistons

thanks

you cant use the ITR rods with the 89 crank. you'll have to get LS sized rods.

use either LS rods with ARP bolts or get some aftermarket LS size rods. you can keep everything else the same

I talked to you about this matter in a PM, didn't I?

Just get LS rods with ARP bolts. Why take the chance with a thicker headgasket?

Just use the right parts to begin with.
