Was just pondering the idea of dropping an sti engine into my wrx 02 . Now I know if I just use all my auxiliaries /ecu pinks and vf35 etc etc it's a straight swap. Bar the use of the avcs control. Now my question will this make it more laggy or as laggy as a non avcs set up? Or is there a loom adapter to use to make them work ? I heard by using the tgv wiring or something?
I've done searches but not seen define answers .

Reason I thought of it was stronger lump for more track work than the stock lump which is all healthy , I can run the 5speed box /clutch set up till I go 6 speed if I do decide that route .
