It's about $2K worth of parts. They are actually 959 parts. I considered it during my last rebuild but my engine builder told me to skip it and this is on a track motor. Your call though..

It is absolutely positively 100% a direct drop in.

talking about the gt3/959 parts, need to figure out the scavenge pump drive. Does the RSR have the drive boss already?

Swap over the chain sprockets and it all should work the same correct? The concern with the stock one is that the bolts could back out.

99310527552 is the drive piece that connects the pump, the gt3/959 shaft doesn't have the provision to accept it out of the box
