JRSC is alright. It really depends on what you want in the car. JRSC is more for low end and mid range power. while the vortech is just all topend. if u just like something a little faster for the streets and not really into drag racing at the track then go with the JRSC. u will make alot more power with the vortech than with the JRSC.
as far as other mods, u should look into hondata, cheaper than aem ems and apexi fc.
also if u run the JRSC, u will need a header with short and fat primaries with a 2.5'' collector. ive made 16whp with the kamikaze 4-1 header and testpipe.
also u dont want to run a cai with the JRSC. u will get all the air you need from the charger so u will need to look into a intake will good throttle response.
look into a fuel pump instead of fuel rail. waste of money, plus for the plugs i used the denso iriduim one stage colder.
