Its all quite tricky this power lark.
At the moment I certainly don't *need* anymore than I have as I am not accomplished enough in the car as it is.
But it's always worth knowing what your upgrade options are in the long term beause it can drive some of the decisions in the short term.
I have no doubt, given another 18mnths, i'll feel ready for more power. I am beginning to suspect that to go to larger power would be more cost effective to sell the car and move up to a car already installed with the 1.8, a better base for tuning.
If thats my long term goal, then I should limit the spend on the current car as the Lord "law of diminishing returns" is worse if you only keep all the trick bits for a year!
OTOH they do say a Caterham is for life and not just for Christmas, and its does keep striking me the lengths some people have gone too to upgrade their cars when it would clearly have made sense to just change car!!!!
I'd reckon longer term something ITRO 160-180bhp would be nice.
Heres another related question then, would it be easier to convert a later K car or a X-flow car to Duratec power? I do like the idea of a duratec 1) because of course I have been brainwashed by the company I work for and have blue blood and 2) I think its likely to be the next Caterham engine choice. Surely the K can't be stretched to meet Euro IV emmisions !!!
