I am sure ths has been discussed before but I couldn't find anything using the search. So, has there been a comparison done between a 911 six and big four, like Jake Raby's engines? Looking at:
1. Overall cost of engine (plus consideration of the cost of the conversion to a six from a four) 2. power hp/tq 3. engine life 4. other issues? |

I see what you are saying, but that 1 time cost STILL works into the overall picture... ok, the lets say this: assuming you drive your teener 30k/year, and have 180 hp a big 4: 7500 up front and about 1.5k every 1.5-2 years(50k miles) or so... for freshening 500 a year for general maintenance (new plugs, wires, cap, rotor yearly, oil every 3500 miles) a /6: 11k up front 3k every 4 years (120k) or so... 1000 a year for maintenance as above. at 1 year mark: the 4 has cost 7500+500 = 8000 the 6 has cost 11000 + 1000 = 12000 2 years: 4: 8000(year 1) + 1500(heads and top-end @1.5 years) +500 =10k 6: 12000 + 1000 = 13000 3 years: 4: 10 + 1500 (top-end and heads at end of 3rd year)+500 = 12k 6 13000 + 1000 = 14k 4 years: 4: 12k + 500 = 12,500 6: 14k + 3k +1000 = 18k 5 years: 4: 12.5k + 1500 +500 =14.5k 6: 18k + 1000 = 19000 even if you do the top-end on the /4 yearly, it will take a while for the overall cost of a /4 to equal the cost of a 6... and I'm being generous towards the 6... and most of us do not put 30k/year on their teener... I don't put 30k on my wife's car and my car combined! sure, the 6 needs maintenance less often... it may not even need it at 120k... but the idea is there... |
