I found the engine to be hugely underwhelming and clattery, being a 2001 pre facelift it came supplied with the 10p engine, swapped out by a previous owner for a 16p with the internal gallery injector return line as most of the 10ps has crapped themselves by now
Under powered, had to rev its tits out to go anywhere and a resoundingly weak torque converter made it rather risky and uncomfortable to own.
Im actually in the process of fitting a rebuilt 3.9/4.0L V8 into my D1 Doris from a D2 with a fresh cam and some nice new gaskets
