Brother Level 1 is a waste of money and time.
Swap a 2ZZGE engine from shershah.
It will cost you nearly 200K with uncut wiring and ECU.
They will take your engine for 75K.
Keep another 50K for labour and miscellaneous work.
Your existing 4 speed ECT auto will work with the engine if you will not abuse it to redline frequently.
Its a bolt on swap you dont have to change many things except for wiring.
It drinks high octane.
