k well my friend is just about to buy a civic coupe with a b16 from a 2000 civic si

well the guy he is about to buy it from was my manager from walmart and he did everything right...

its been dyno tuned and laid 170 whp...

this is what i know it has...bolt on wise
AEM cold air intake
HKS cat back
no headers

i told me he did a stage 2 setup from i think from group 5 or some place in mira mar
i know it had a 3 angle valve job
stage 2 cams
cam gears set at 0
has a VAFC
i know the head has been built and he meantioned that the bottom was too but i not sure

this car is very clean and all dont right

170 is nice but he wants more like everyone else...

soo the question is what parts are worth adding on to get more power...dont really want to redo all the internals due to the fact he just got the motor work done....

just let me know what bolt on's or anything that will give the gains..
ohh yeah the vtec controller is set at 6 i know people that set it lower...is this good or should he turn it down?
