Engine Mechanical problem
1994 Nissan Skyline 6 cyl Two Wheel Drive Manual 51000 miles

i just recently replaced my head gasket replaced after it went and got new plugs timing belt kit done and the car is driving grand now, i heard that you have to get it remapped after the head going, but i hear from others that is grand so i just want your opinion, i cant afford to remap it and it seems grand so hope to hear from yas soon thanks...
