ok here we go,
full front clip s13 black top $3000
install parts misc. etc(hoses, fluilds etc) $150
clutch kit $320
downpipe/ custom 3inch echaust $150+say300
JIC Magic FLT-A2 $1600
oh yea the bushings kit ST, around $90
its a bitch to replace all of them, lots of work.
this for almost stock setup engine wise, id say you can go for Tein HE,
will be cheaper,
this just of top of my head, so
after all around 6k is not enough, if you do the engine, you gotta do it right, just like everything else. you can start with suspension and keep saving.
$5000 should be net reserve for the engine.
