My sc400 needs more power. I'm not satisfied with 290hp, well maybe 300 with the newly customized exhaust. I would like to drop a 75-100 shots of wet zex nitrous but I've heard people say the 1uz vvti can't handle the additional hp due to weaker rods compared to the non-vvti motors. Is this true? Would this really be a problem? I don't want to supercharge or turbo it either.
