Need some advice on cams

My set up is s13 blk top Sr with 740cc injectors a gt2871r turbo and a walbro 255 fuel pump and fmic Im planing to get hks cams but don't know what size

You have to have the valvetrain built for HKS or JWT cams -- I run some greddy easy cams and love them. They do not make as much power up top but close to HKS and JWT without the valvetrain upgrades necessary to run them. easycams FTW

[I ask good questions]

No, you can run hks step 1 264's and jwt s3/4's without valvetrain modifications. I would suggest some jwt s3's though. Many people would argue they are the best overall street cam on the market. Also, my personal opinion is to stay away from the BC 264's. I know they are cheap and tempting...
