i voted for rb.. but iono maybe b/c its a skyline motor. haha.. but anyways, after considering options..
s14SR and RB25 cost about the same for a front clip. however, RB will cost more to drop in since it needs custom mounts and driveshaft, etc.

Wiring will be a little different for both. RB probably has the ability to handle more boost SAFELY since its spread through six cylinders compared to four thus making more power. But depends on how you build up each motor. If you stroke the s14sr to 2.2L than you might have something.

Price of parts is quite different as well. It will cost MORE to buy RB parts since they are rarer and SR parts are so popular that most of them are in stock in the US. also considering, you have to pay for more stuff since its six cylinders (ie. 6 forged pistons comapred to 4, 6 injectors to 4, etc.) higher price parts for the RB since the demand isn't as high as SR parts. etc.

Both can make great power. I think the S14 sr is more bang for the buck compared to the RB unless you have tons of money and money isn't really an issue and you're going for more power and more bling factor.
