Just curious if there is aftermarket support, mods, information, discussion going on with other similiar architecture v-8's such as audi 4.2, bmw m62/s62, nissan vh45, northstar etc. I happened to see an awesome sounding and quick lotus esprit on youtube with an audi 4.2. Do the above mentioned (and similiar) engines have parts available such as pistons, cams, rods, flywheels and transmission adapter plates? Do these parts match the price of 1uz aftermarket (i have definately seen some crazy prices from Dinan for BMW aftermarket, much higher).
