Yes with the correct ECU etc you'll go through turbos like no tomorrow though lol The Evo I went in had the turbo off an ex WRC car the guy flew to Finland just to buy it
No worries dude I was absolutely shocked when I seen a few cars on them couldnt even tell they was lowered tbh. But yea ep91 springs will fit ep82's and vice versa
STAY AWAY FROM THE TEINS!!!! Fucking bullshit claims that they lower 57mm they wont go lower than yours is atm PI used to make 60mm springs but were very rare and dont think you'll come across any. Save for coilys you wont be disappointed
