Engine model

[Bwagz]

I bought an engine from a friend of a friend many years ago, it was sold to me as a RB25det Neo. 
 

recently I started pulling it apart and noticed that the intake manifold was pretty different from others that I had seen on RB engines so did a bit of research and found that it was a non turbo manifold. So I’m sceptical now that it is a NEO DET and just thinking it’s a NEO DE (it does have a turbo strapped to it currently). 
 

can you identify the engine model from the numbers on the block?

No. The castings are all the same.

As you have the inlet off, simply measure the diameter of the inlet ports and compare with the freely available on the net sizes of turbo and NA. The NA ones are small.

Going by the intake & injectors I'd be guessing it's a DE, check the head casting number, should be 5L8 on a DET, 5L7 I think is the DE number.

Thanks for that, hadn’t used my brain enough to think about that.
