Check your compression and boost leaks.... stock sr red tops typically are 205hp at the flywheel. s14 sr's are a tad more
Compression should be around 160 for each cyl
I made 202hp 198ft tq on full stock motor with lightend flywheel s14 fuel pump and greddy fmic, type rs BOV 3" pipes, series II redtop with timing retarded. 3" full straight exhaust with test pipe.
