ok, i know this guy with a totalled 96 integra ls. is t boned in the rear. he will sell it to me for 400$ and my girls brother is willing to put half cause he wants the seats and front end. i would take the ls motor tranny harness and ecu. my question is this. how much better is the gs-r block compared to the ls block? if i use the ls block with the gsr head, will that be a good setup if i change the internals and go for 400 horses? or would it be cheaper in the long run for me to just stick with the gsr swap(wich costs around 3k)?i mean if im gonna rebuild the bottem end of the gsr block anyway then would there even be a difference wich block i use or is the gsr one stronger?i know the gsr head has better air flow but i could just get one on ebay for like 500-600$. how hard is it to swap it onto the ls block? anyway let me know what you recomend
