Talking out loud... my L27 plans.
ok, i'm posting this here in order to get some reactions, opinions, suggestions or constructive critisism. if my ideas are stupid, ill choosen or simply won't work please feel free to tell me. if you got a better idea, lets hear that too. but please don't tell me to just supercharge it or just drop in a series 2, because i've already decided not to.
i want to see how much power i can get out of my L27 in naturally asperated form. i'm not expecting massive gains, but i'd like to see it around L36 levels, or more if possible. i know that an engine is and engine and if i wanted to pour money onto it i could have a naturally asperated 800 hp L27. but i know that realisticly, that won't happen either.
lastly i know that upgrading the motor will probably be easier and yeild me more power, but i'm a sucker for being the underdog. there'* just something about it. the thrill of doing what people said couldn't be done. it'* satifying. it'* like getting your fat chocolat covered face stuck up on the wall-o-shame at an ice creame shop for finishing the "you-can't-finish-it-sunday" take that, everyone who said i couldn't.
so here'* the plans i have laid out right now.
*correct known problems
*give engine a thurough tune up
*remove AC system
*180 degree drilled t-stat
*adjust tranny mod & tranny cooler
*replace vacume lines
*NGK'* plugs, MSD coils and wires
with this i hope to gain back as much lost horsepower as possible
*port runners in heads
*port exhaust manifolds
*high flow cat
*matched fuel injectors
in stage II i hope to gain as much flow as possible with the stock parts to unlock hidden horsepower. really bring it to life.
*higher ratio rockers
*shave head to raise compression
*springs and pushrods
*underdrive water pump pulley
stage three really focuses on pulling more power from the stock heads
*custom high compression pistons
*knife edged crank
*stronger rods (shot peened, cryo treated, custom?)
*balacnced rotating assembly
*rebuilt transmission with LSD and 3.73 (?) FDR
stage IV will be a stronger bottom end with a slight displacement increase. the power here should come from the increased compression and the cam. a beefy rebuilt trans will be installed at this time to help handle the load.
these mods, especially the later ones will be performed slowly and over time, as i can afford to do them. or possibly not at all. at this point i'm parading my ideas in front of you risking ridicule and the death of my already fragile and small reputation.
better ideas happily accepted. please follow "that won't work"* with "here'* why"*
