As I stated before, He can make 500 N/A But he wants to do a twin turbo,
wether or not its just the fact of having it +1 for coolness factor,but +2 for easily bumping the h.p. when he gets bored of 500hp!!!
500hp very easy w/twin turbo setup @ low boost settings, the BIG + for this is since he has a low #goal, will not need huge injectors or have to run meth injection.
OKay NOW..... Back to the OP.383ci very cheap these days to do. Look into a forged setup ie:
Eagle forged crank,Rods, pistons etc.. (these will put you to about 750hp limit)
machine shop can easily do the work for you with your stock block.
Cam: you can go with realitivly high lift cam, just make sure the duration is close along w/ lift ie: 208/212 .491"/498" (not suggesting this cam, just comparison for the split of #'s your looking for!!!)
F.I.:tpi setup ok, you will need to run a 2 bar map, run it car in speed density (some yrs. were in speed density, not sure what yrs. early lt1 z28s I believe)
60lb. motron injectors
twin walbro 255's intank (modify bucket to fit)
Turbos: 60-1 (t60's or t61's will work great)t3/t4 housing
for very quik spool order with a .63 a/r exhaust housing
for good spool with broad boost/rpm range use .84 a/r exhaust housing
dual 38mm wastegates will do ya just fine
headers/piping: 1 3/4" primaries, 2 "- 2 1/2" hot side to turbo, 2 3/4"- 3" out from turbo exhaust housing merged to single 3 1/2"- 4" to muffler
intercooler: 3" thick 2.5"inlet/outlets all cold side 2.5" then to 3"+ right before throttle body.
All this here will get you 500hp in a heartbeat !!! just crank the boost up to 10-15 lbs and you'll be 750+
good luck w/ build.
p.s. my dream when I was 17 was to have the first twin turbo Z in South Jerzy, Now its finalyy getting done, I just won't be the First !!!
(but I might be the fastest
)
