Space under the hood is so limited & KITS r KITS they do not address all the problems u will encounter. l work on several single & twin turbo 350Z cars & none made it very far on stock motors before we pulled the motor ported & polished inlarged combustion chambers different forged pistons & valves valve springs. Oil pan extensions Carbon hoods with plenty of vents & hacked up front bumper covers to accomodate large inter coolers.
