To get 1000RPM sooner spool and still make mid 400s the HTA green would do the job with meth "with the right supporting mods of course". Some Kelford 272 cams would add some more top end but lose just a little spool and you would need aftermarket valve springs... It becomes a balancing act as to what you want out of your car honestly. The GSC S1 cams are a good choice if you want more power across the rev range and dont want to change valve springs and lose VERY little to NO spool which the OP didnt want to do all that.. That is why i suggested he get the GSC S1s and they fit the bill and did there job perfectly! They didnt lose any spool and the car actually feels more powerful everywhere after the cams!

Also take into account this is on straight 93 octane pump.. no meth... So with methanol or E85 i could have this setup coming in sooner Also starting the pull sooner will net peak TQ at a lower RPM as boost will come on sooner.

Depending on your overall power goal will determine what turbo you need to go with.
