I'm building a 2g 7 bolt 4g63t and target power is about 250 whp, turbo code is TD04 16g. I'm going to make sheet metal intake manifold and I know good plenum size is 1 - 1.5 times of engine size for nice powers, I my target hp is not huge, I wanna know what's best plenum size and runner length for my application with very nice throttle response.
