SR20VE head can be bolted to a rwd block. You will need to run the VVL oil feed externally which isnt too hard to do. You will also have to get a custom intake manifold made up or get an adaptor plate made up so that u can use a standard rwd manifold with it. I had a SR20VE in my old sss pulsar and loved it. It was quicker than my mates R32GTSt before i did any work to to the engine. Get a set of franklin cams, dual valve springs and adjustable cam gears and should easily make 120kw+
