ah k.... but if u use the SOHC ecu wouldnt u still have fueling issues as the ecu wont be able to compensate for the airflow caused by the turbo.....
no to mention the lack of a knock sensor..... which comes with the BPT....

just as an option thats not too expencive....
a aftermarket Link Plugin ECU ( around AU$1200 )
these ecus are a direct replacement for the BPT ecu... but i dont see any reason why it cant be reprogramed to work a SOHC engine....
check out http://www.link-electro.co.nz/ for more info....
the Link plus is a better option, but more expencive...

The reason why you can run 15 psi on a stock BP09 ecu is because with an MSD ignition system with igniton timing retard you can trick the ECU that instead of advancing like all naturally aspirated engines do, retard it depending on how much boost is felt.
Obviously there is a limit to setting the ECU correctly.
Other factors come into play like adjusting the springs in the AFM
Use cold spark plugs
Install SOHC manual tranny pistons
Anyway, the thing is the ECU is never touched at all when running on boost.

but besides that, that's a good idea to use lower compression with a turbo with the help of your ex-engine. DONOR
