Hey Carlos, yes same engine, except the R8 has a dry sump.Is the RS 4 4.2 block the same as the gen1 R8 4.2 the same block? Meaning if I have a bad R8 4.2 can I use the block for the RS 4 in a rebuild?
I'm am just looking to use the short block, with my heads.Hey Carlos, yes same engine, except the R8 has a dry sump.
I'm not sure if it's swapable - the ECU may be different as well a mapping, etc. But if you're talking about the block only, it should be swapable.
