id buy motor from Enjuku personally, only because my SR from them was hella strong running and lasted through abuse and more abuse.

CA i agree with sean on the lack of aftermarket parts. and its heavier i think... its cheaper sure, but its end potential is not that great.

LS swap is no where near the same price as a SR/KA-T style... thats a lie lol. You might get lucky, but typicall SR swap is 2500 for most everything you need to 'start the car' and then you can upgrade, where just the motor/trans/computer for LS1 is usually 2500+ and then you need lot of custom/kit mounts and lines and a driveshaft and the list goes on. Typical 'cheap' LS1 swap is gonna run you $5,000-6,000 + to be running in a reliable way.
