Im building a ZVH and i have a few turbo bits in the garage to build a turbo and then send for balancing. What Power range will these roughly give me?

option 1. A/R .42 55 trim compressor wheel A/R .48 exhaust

option 2. A/R .60 compressor A/R .48 exhaust


Engine mods are forged pistons
Stage 3 head & PE cam
Megasquirt MS2
FMIC

 

with the brief spec you have given (zvh) would be hard to know for sure. But roughly the first can flow 230 and the last 260. Obviously depending on boost levels and head cam turbo cooler etc etc etc..

Been asked loads of times on here and gone into depth on countless post have a search.
