Hey

I own a Evo X gsr and i want to upgrade my boost on the stock turbo.

My question is how many boost can i reach on 93 octane and what product i should use to do it.

Thank

 

Hey buddy there are many steps one should take before simply raising the boost. The most important way is supporting mods and you should AT LEAST get an Intake, a full Turbo Back exhaust, and then get it on a dyno with a tune. That said 24PSI max but it probably won't hold.

 

Yea i already got all my supporting mods.

 

get a grimmspeed 3port and tuned. the max is 26psi but it will taper to 19 at redline cause the turbo cant flow anymore than that.

 

This, and remember it isn't always about the boost, it's the tune handling the boost.
