thanks for all the help guys, i really appreciate it.
As far as the NA rear mod goes, how much would someone charge for that sort of thing and would it somehow hamper my driving at all or cause things to be more prone to breakage or failure?
The 50 pounds less thing sounds good since all i do with my cars is just add sound systems and that weight displacement would be quite nice

.
I just hope by the time i have all the money gathered up i can get myself a good one.... *prays and prays*
