You can lock out the timng and run 36deg BTDC, Then use a boost retard box to retard the timing
as boost comes in.
The cam is not a good "turbo cam" A single pattern 224-224 n 114 is better.
or a 234 intake 224 exhaust @.050" cam on 114+LSA .. with 234 duration the boost will start late.

I would reinstall the 224-224 114 LSA cam but degree it in and install straight up in 114-114 centers.
Instead of advanced. It will have the top end power you wanted and build turbo boost.

Too much overlap and exhaust duration on the closing side allows the turbo boost to go right thru the motor.
Its easy to over cam a turbo motor.
