Sup guys ..I just got another colt gt but the head is cracked so.. Would swapping a 63t in it be legal and would it pass california smog? Or just running the 63t head would it pass? Thanks... |

it will fit, but as per Jon Ripple (Team Rip Engineering), the 63t head on a 61t block will kill low end torque. though some say its fine. given the fact (with the exception of the cam lobe duration) the 63t & the 63n/a cylinder heads are identical. you might want to try to use a 61n/a head on your 61t block (the 61n/a even have the turbo oil feed line tapped, but plugged just like the 63n/a!). since the 61n/a Mirage/Colt/Summit are super rare, I'd use a 61n/a off a Hyundai elantra. not to worry tho, the motor is all Mitsu. then U can transfer your higher lift duration cams over from the 61t, &/or use a 63t exhaust cam for max top end performance. good luck. |
