i thought we come stock with close to 240hp ? making an extra 60hp shouldnt be that hard . you figure 5hp u-bend delete , 10hp 3" downpipe , 5-10hp PLOG . right there is 20-25 hp . plus you add a pcm , colder t-stat , colder plugs , air intake of some kind you can figure at least 30-40hp gains then do a smaller pulley (if KR allows) you can see close to 300hp . right ?????? :th_scratchhead: seems right to me anyways .
wow kid, you need to read up on your mods. half that stuff wont add even 1/4 of the advertised horsepower.
to hit 300 hp with these cars you will more than likely be cammed with a fullsize intercooler as preotic said. that said, these cars are the ones most likely to be running in the 12s with a good tune. people run 12s with rockers on a nice free flowing setup, but it just doesnt have the overall powerband a cam would.
for a quick car to have fun driving id do:
header/plog and downpipe (preferences/money), 1.9 modded rockers, a 3.4 pulley, and all the other supporting mods (intake, t-stat, etc.). adding a ported blower and throttle body on top of this only helps to reduce kr. i wouldnt see anyone being able to daily drive a 3.2 pulley on this as it would require low timing and the car will run overall worse.
for a fast car that youre going to drive on the street:
list above, but headers for sure and some sort of intercooler. short stack youd be able to run around a 3.2, fullsize youll be able to run anywhere from a 3.2 down to a 2.8 depending upon tune.
for a balls out fast car:
instead of rockers you need a cam. upon this would come into the area of heads as well, expensive as fawk.
so really..make up your mind on what you want your car to do and how you want to drive it before you ask what you can put on your car. also, with all these parts, installing them may be a problem if youre not mechanically inclined. in this case, dont mod your car any more than bolt ons and dont ever drop a pulley.
