Did an Rb25DEt VVL and the rb20det fuel pump is not enough.
The inlet mani IS NOT appropriate..
The front pipe of the exhaust is different.. I.e it has different flanges and will not mate appropriately..
And be warey.. please tell me if after the conversion you have difficulties with the engine starting hard.. I found that the first week or so it was sweet as, and got harder and harder.. to the point it has to crank over 6 or so times to start..
other wise everything else you have seems to be in good order
