Which parts needed for ZX-5 RTR to SP

[GO_OUTSIDE!]

Hi I'm new.
I have been browsing today and am left with a question. If the LAW35 SP conversion kit is indeed discontinued (KYOSHO is accepting backorders) what are the parts needed to convert an RTR to an SP?
What are the advantages of the conversion?
I havent driven my new car yet and I havent raced in 15 years but after watching some of the video footage of the ERevo pulling wheelies I am certain I will be upgrading the motor. Nothing crazy, just halfway crazy.

I'm nearly 40 and am waiting for my new toy with the patience of a 6 year old.

Thanks
