ls+boost equals the ultimate set up.. ls motors love boost due to there low compression.. while the b18c1 isnt so boost friendly.. all this about ls/vtec not being reliable?? it counts on how u build the motor.. if u build it wrong the motor will go BOOOm in a short while.. if you build it correctly it will run like a champ... a properly built ls/vtec will make more hp then a b18c1.. o yeah btw ls can just be as fast as a gsr just gotta have 2 thing $$$ and a good tuner who knows his sh!t.... didnt u see the sport compact mag with a 11 sec daily driven hatch powered by a b18b1 with boost??
