JDM 2JZ-GTE overboosting, any chance not using restrictor ring?

Hello guys

 

My car is 1997 JDM Supra 2jz-gte

 

it's full BPU

has fmic, exhaust, DP & MP, MINE'S ECU, Dual intake, boost controller...

 

 

 

we all know that JDM 2jz-gte stock turbos are known to overboost without stock catalysts

 

I really really want to remove the restrictor ring as I don't like the idea where there's just a 50mm hole for exhaust :s

 

 

 

What if I modify the stock wastegate hole? make it bigger, it's only 26mm in diameter and it can be modified to about 35mm

 

 

here's how the stock one looks:

And this is what it can be after modifying:

the question is, WILL IT REALLY HELP ?

 

I don't want to use the restrictor ring because I think it restrict an exhaust and I'm loosing some power (Am I right?)

 

 

oh and I know I know

it's too much hassle

 

but I'm on vacation and have plenty of time so it won't be a problem removing/installing stock turbos
