The AU has much stronger bottom end, designed for higher rpm ....
Take rocker cover off and check that its rather clean before buying..
Even fitting std AU in E series gives more performance and economy..
Fit Std A.U and change final drive to 3.45 and you'll have an XR6 in lighter body..
Even easier if you fit A.U motor and box..
Avatar is AU turbo in E series..
you make some good points but having "clean enough to eat off" rocker gear means fvck all. ive destroyed 2 wrecker AU motors with claimed "less than 150k" use both with impeccable rocker gear. Also with probably no more 200-250hp
(not in response to EBTO4z)
also replacing motors fucking sucks. You can build a decent bottom end for under $2500. I bought acl race pistons - rods shotpeened. rotating assembly balanced and assembled. Its not a forged setup but tough enough to warrant swapping several stockers when they go boom. plus 400rwhp would be fine with dialing beatings in my bottom end. When you think if you pay 300-400 for each wrecker motor. 2 of them plus coolant oils. time. effort. get fucked
