My car is a MY 05 Twin scroll JDM STI. When it was last rolling roaded it gave 349 bhp @ 1.3 bar on a K+N panel filter. Since then it has had the Typhoon fitted + 3 port boost solenoid + remapped @ 1.5 bar. I,m having a Japspeed front mount fitted this week and I,m thinking of getting a bigger turbo. Was wondering at what stage would I have to uprate the Typhoon. Steve.

K&N Typhoon should be OK for 400bhp,above that would go with RCM/GGR kit which are mostly used,not sure if you want stick with your ECU above that,if yes would suggest big MAF tube,but for sure would speak to your mapper
