Hello everyone. I have a 23 Forte GT and I’m wanting to give my GT a bit of a boost. This is what I want to do to the car:

XForce exhaust (already done)
Afe stage 2 CAI (already done)
Intercooler (pre ordered)
JB4 93 tune (arrived but not done)

I’m assuming all of this could put me around 225-230whp. What I want to know is are there any other supporting mods I should do to make sure this car is fine at this level? And what power does it start getting bad for the engine/turbo?

thank you guys.

I believe people recommend running a different spark plug with the piggyback, and I'd highly recommend a catch can. Other than that, as far as I know you should be fine. I'm sure others with similar mods (aka basically every GT owner on here LOL) will chime in

I'd throw in bushings for engine and transmission from Powerflex, a BOV that can handle more boost with a N75 BOV solenoid, and (optional if you have a 6 speed) the BMS throttle controller to complete the JB4.

I learned that how you beat on a car has more influence on reliability .. and some cars are just troublesome for one reason or another... the mods you listed have little to no effect on long term reliability.. the dealership will not agree with me.

Do you have a recommendation on which spark plugs? I’m sure I’ll be able to find a readily available catch can. Thanks!
