GRIM Posted July 3, 2012 Share Posted July 3, 2012 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 Quote Link to comment Share on other sites More sharing options...
