I regards to plain desire I don't want a SR20 because they are a very common swap in 240's but my question is which setup of three is more beneficial for a drifter setup in a 240sx. I have had so many discussions saying that the RB motor is to heavy and throws of the balance of the vehicle but I thought that could be compensated with a more heavy duty suspension system please tell me what you guys think is the better setup.
Welcome to NICO, Rbtuning32.
Whoever told you that the RB motors throw of the balance of the car to any significant degree is wrong. Sure, it's added weight over the wheels, but it's not that much (at least not relative to the total weight of the car) and it certainly can be compensated for. I mean, depending on your setup, you can scoot your seat about a few inches and get back to the stock weight distribution.
There's a LOT of misinformation floating around out there. For instance, the only RB transmission that you'll ever use that is stronger than the KA transmission is the RB25 transmission. If you go with an RB20, the transmission internals are identical to the KA. Rest easy, though, because the KA transmission has demonstrated an incredible degree of strength in KA-T applications.
I'm not going to solve any issues for you, man. It's your decision, from purchase to install. I would recommend that you swing by the 240sx General forum and check out the engine-specific forums to get an idea of what you can expect in each motor.
Take it easy and again, welcome!
