Got 90 240sx with 5.3 lm7 with ls1 intake manifold, 1 3/4 long tube headers, dual 3in to single 3in resonated exhaust no cats or muffler, 40lbs injectors with untuned 😔 lm7 ecu, big hot air intake, and 2005 GTO t56 transmission with b&m short shifter.
got it like this and threw it on the rollers before I start modding it and it put down down a disappointing 269whp with 318trq.
bought a ls6 manifold and will tune it after that. Will eventually add a cam and either swapping a lq9 with some heads in it later or lsa supercharging the 5.3L. Haven't decided yet.
