Increasing the displacement in the TR8 is pretty easy. Upping the stock 3.5 to a 3.9 can be done with new sleeves and new connecting rods. Easy engine swaps are the Rover 4.0 and 4.6 (like the ebay item). External dimensions are all identical. That particular engine would require a custom hood, notice how it's off in the photo. Those carbs and air cleaners stand far too tall. I have seen TR8's in England with 4 DCOE's instead, which offer zero hood clearance items. The TR8's in England that I spoke of are Rally clones and can push more than 400hp. /ubbthreads/images/graemlins/driving.gif
Also, the fuel injection systems that are used in the Range Rovers will fit in the TR8 as well, though you have to take out or modify the fresh air plenum.
