B18C Blowing smoke only during vtec under load ??

as the title says my b18c is blowing smoke but only under load in vtec, Any sugestions or things i could test/try would be great

compression test was done 10,000kms ago and was 170ish across all 4

I have a short list of mods running with a stock ECU but nothing to major
skunk tunner series stage 2 cams
edelbrock manifold
68mm TB

i'm also running an oil cooler in prep for turbo and have added 3 washers under the oil pump relief spring to raise the pressure

black smoke or white smoke?

defs more on the white/grey side

i've been lazy and havn't looked into it but i gota get it sorted so i can finally put this turbo on

black smoke - running rich on fuel
white - water leaking, usually head gasket. check for milky coolant or oil
blue - oil leaking into the cylinders

heres a good link i found on google for you
