The JRSC is a pretty decent model, but the GSR kit only adds about 60hp. you might be able to squeeze 75 out of it if you get a hondata or chrome system. even if you can find a used JRSC for about $1000, you will still need to get bigger injectors and a good ecu and tune.

Jackson racing offers a stage 2 upgrade kit that consists of a tuned hondata s300 ecu, rc440 injectors, and two high boost pulleys for around $1500. If I were you, I would go that route. the stage 2 kit adds about 100-110whp over stock.
