[Ä‘uro]

What can happen to g-lader nd engine if I put i/o original trottle totaly different trottle without boost return valve? i know the whole boost will run into engine but can I regulate boost with blow off valve?
So when I push pedal, boost will go to the ongine nd when I pull the pedal off surplus of presure will go out fm pipes through blow off valve

Can this system work on G engine?

No- you'll be trying to force air into the engine at all times.

You need the proper boost return valve, dump valves can't flow enough.

Is there any other option?

Use a GT throttle body with TPS and modify a G40 BRV to suit, shouldn't be too hard, only 2 bolts and 1 linkage.
