Custom/Hybrid Suerjet and Waverunner III simularities

[StandupWI]

I was wondering what are the simularities between the Superjet and the Waverunner III. I really want to know are the intake grates and ride plates the same, along with driveshafts (or the pump to midshaft bearing). I found a cheap Waverunner III to to scam the pump tunnel for a 300sx build, but didn't want to get stuck with putting it in and having no intake grate options or the driveshaft being completely wrong.

Every WRIII I've ever worked on had an aluminum pump tunnel that is too long to use in a stand up. The driveshaft is longer, and the pump wear ring is not threaded, so it doesn't fit a SJ without modification. The midshaft is long, but had a 90-93 SN style housing. The motor and pump stator would bolt into and SJ, but not much else will be of use.

It depends if you are comparing a WR3 650 or a WR3 701 to superjet SN 650 or SN 701 or RN 701.

intake grates- different all models
rideplates- different all models
driveshafts- different all models
midshafts- different all models
pump stator- similiar depending on model- can be adapted
wear ring/impeller housing- similiar depending on model- can be adapted

bearing housing- same for 650s
bearing housing- same for 701s

engine/bedplates- same
ebox- same except power cable and coil wire lengths and different ebox harnesses
