A 3UZ has become available to me, and I'm considering using this instead of sourcing a 1UZ.
I'm aware of the differences in internals across the early 1UZ, later 1UZ and then of course VVTi on the latest 1UZ and 3UZ.
I'm almost certainly not going to go forced induction, so later 1UZ is a possibility, and the lighter internals should help a late 1UZ or 3UZ to rev more freely.
However, I'm aware that as you progress through the engines from early to later, there is potentially more in the way of issues around immobilisers, removing auto boxes without upsetting the ECU etc.
Is a 3UZ going to present more of a wiring challenge than, say, a VVTi 1UZ?
As and aside: I've been discounting the 94 to 97 1UZ, because it is neither as strong as the earlier ones, nor does it have VVTi, but perhaps this is ruling out some decent contenders for my project? As mentioned, the strength of an early 1UZ probably isn't required. Are the electrics going to be any easier on a mid 1UZ compared to a VVTi 1UZ or 3UZ? I know that at 94 they started putting immobiliser coils in the ignition barrel / key. Anything else?
Thanks!
