Yes

I've seen a DOHC nissan V8 in a Datsun 910 so no doubt one will fit in an R31...

There's a V8 C110 around here, a V8 C210 as well as a V8 R33 (I think). No reason you can't put a V8 in an R31. Make sure it's a late model block though, as you might have rego / epa issues putting an early block into a late car.

Lucky for you the RB30 is a heavy lump of an engine, so just about any V8 is going to be lighter. (mmm LS2 anyone???)

Unless you wanted to do something different, (which a V8 in a R31 is), why wouldn't you just put a turbo on. So long as you don't go stupid on boost, and RB30et conversion is very tractable and nice to drive. I like the torquiness of the RB30 standard, putting a turbo on it makes you forget how heavy the motor is, and how nice the thing is to drive. I personally think spooler noise is almost as nice as V8 burble.

V8 in R31 is generally not a problem, your only concern is registerability, now there is a good word eh!

Rules to work with are capacity based and to find your absolute capacity is like this.

For n/a conversions 3 X body weight is your answer, therefore an R31 is approximately 1350kg, 3 X 1350 = 4050, you might get away with a VH41.

turbo is 2.5 X, thus 1350 X 2.5 = 3375, so in this case you lose and RB30 is your only option.

Doesn't matter wether V8, or V6, or V4, the absolute capacity will be the final answer.
