RB25DET 240sx Swap

Im just weighing out my options at the moment, gathering up info on each swap (SR and/or RB25) so that in the future, IF I DECIDE to go either route, ill be prepared … Ya bout turbo-ing the KA, ive read some articles & forums about that & from what I heard its good for saving money AND like you said, you pretty much get the same amount of power “more or less” lol … But heres the thing, my KA is pure stock n still going strong at 280,000 km LOL … Im just waiting until i cant get any more “purrs” out of her then ill start weighing my options in real time (bolt on turbo? SR? RB25?) …

Now heres the thing, is it worth to rebuild my KA n bolt on a turbo or jus do a swap for an SR n put some extra mods to the SR for more power? (im not including RB25 cuz it has its own criteria lol)
