the stock coil and stock electrical stuff is good enough dont waste on msd stuff,,,,only on spark plug wires!,,,,,,,, stick with the oe opti also, just open it and check the internals if they are cracked or something weird about them, place red lock tite in the 3 scres on the rotor....
headers: pacesetters long tubes are affordable
on the other side, you could have your stock heads ported, and build a combo your self but this will not guarantee that youll have an improvement on the heads,,,,
the stock manifold match ported to the heads and just cleared in the inside is good enough , you dont need to change it as far as I know up to 600whp plus or more, so, leave the stock one, 300 bucks for the budget part,,,,,
check le pacages maybe you could save some more money, and youll have just want you want, and you wont be desapointed on the part,
Ps: do some research dont rush everything cause youll end up disapointed!
you will not get that easy to the 400whp without heads, so LE pacages seems a nice option,,, having a le2 pacage would get you there easy!....
so if you choose not to go with msd stuff you have an extra 500 bucks right ?!
