I have a 94 Legacy single turbo, most of the engine parts like intake manfold etc is still off the original RS engine but the block has been replaced with a fully rebuilt block out of 96 RS but has been built for single turbo.

the ecu is out of a v4 STI and the car runs mint except for the one fact that im still running the legacy turbo (vf10). i want to upgrade but do i try get my hands on a vf24 which is found on v4 sti or can someone help me to find a better suited one like maybe a TD05.

turbo starts spooling about 2.5k and hits full boost at nearly 4k but then dies out higher in the revs

sssssteeeee

indeed a tdo5 18g or vf34 would be a good choice, best would be sc36 billet from scooby clinic.
