Hi Beemer...I am jazzed that you are energetic enough to persue excellence of performance to the degree you have. I have found that with every new engine mod comes a new problem, or co-efficient that needs attention. As I get older, my focus is maintenance with moderation. I believe these very european Land-Rovers are designed for "upper-established income brats," and all of us "off-road cats". therefore, I restrict the modification levels for my rig, to satisfy the basic remedies for going into the bush as often as my schedule allows. I think that research and development will take you down some interesting and expensive roads.....and I will try to be there if you need my assistance, but I do not have the expertise that you obviously have with engine-mods, so I will not try to develop a thread based on these periferies. But...I want to know how well your mods stack-up when you are finished with your rig! I live in Tennessee...where do you off-road?
