Sorry, but if the plan is to eventually rebuild either way, to run 10's you should just bolt a nitrous kit onto the completely stock motor and run it at 14psi on the stock turbos with a good tune on a pfc and some drag radials. $1500 for the ECU, $600 for the tune, $1200 for the drag radials, $1000 for the nitrous kit including a bigger fuel pump, $1000 for the clutch, $15 for a boost controller, (hey this IS sau after all and you're all cheap kents!)
Adds up to under $6k
If it dies, rebuild it then. Not before.
