ok my friend has a 99 civic with an ls/vtec and he now wants to add n20,he planned on upgrading to eagle rods and weisco pistons but wanted some input on if it would be safe to run it and what kind of shot he should run,here are the specs on the motor:

ITR AEM COLD AIR INTAKE
ITR INTAKE MANIFOLD
BORED THROTTLE BODY 64.2MM
SKUNK2 STAGE 2 CAMS
SKUNK2 CAM GEARS
RC 440 INJECTORS
JDM B16 PISTONS
LS RODS
HEAD WORK PORT AND POLISH/MILLED HEAD 30/1000/RACING VALVES
SKUNK2 VALVETRAIN
TODA HEADER
TYPE ONE EXHAUST
COMPRESSION IS AT 12.2 TO 1
HONDATA S200 (PROGRAMMED TO REV OUT TO 9 GRAND)

easy 100 shot, maybe even 150. not quite sure though

wow he shouldn't be revving that high at all to start let alone spraying 100 shot or even maybe 150 as posted before.

do rods and pistons other wise think of your rod and well ever step on a twig?

ok so you think he will be safe if he does rods and pistons?,he will seldom use it and only wanted to run a 75 or maybe 100 shot

rods yes will be needed and depending on what his goal is pistons might be a good idea.
