LS engine can run between $1300 - $2300 for one in great condition
GSR can be better.......depends what route you plan on going with the motor.
go with cat-back exhaust, aem intake or just a simple K&N drop in filter (since the Honda engineered intake is so damn great), a short shifter, and DC header...........however another wonderful idea would be........
K&N drop in, cat back exhaust, DC or Kamikaze header and a ZEX kit
oh and maybe a ZEX camshaft to toss in there along with a Venom adj cam gear. bada boom bada bing
