Question about Supra 1987 87
A turbo works from expanding exhaust gasses
on the smaller turbo the gasses fill the snail and turbine wheel exactly
That is the engineered design for that size engine
however with the bigger turbo there is not an increases in exhaust gasses to actively drive the turbine so it has been a wasted exercise
with turbos , bigger doesn't equal better as it has to be in relation to the gas flow from the exhaust
again if you haven't reset the ECM for the extra fuel needed for the bigger turbo and inlet flow then there is not the hot exhaust gasses needed to drive the turbine wheel to create the extra boost
