i melted a piston last time around on my b18c due to poor tuning. im not looking to do it again. i have searched and honestly i have a headache because of all the mixed thoughts. so if someone could clear up some issues it would be great.

previous setup-
drag kit with master power turbo
440 cc injectors
walbro 255 pump
hondata s100
so i ran this with a basemap because my builder said it would be fine. turns out he was wrong.

new setup-
drag kit with master power turbo rated at 440hp
1000cc injectors
walbro 255 pump
sleeved block by camp1320
cp 9.1 pistons
eagle rods
acl bearings
golden eagle head studs
oem head gasket
hondata s100
omni 4 bar map sensor
rev valve train
endyne catch can

my questions are.
do i need really need cam gears,bigger fuel rail, msd ignition?
also will my hondata s100 be enough for this?
any thoughts on bore size?
im not really concerned with costs. what i am concerned with is blowing my motor again. im looking to make this a daily driver with a good powerband around 350 400 ish.
any thoughts or recommendations would be real helpful. its my first big build so i want to be as safe as possible. thanks

-You'll be fine with the S100
-The stock cam gears, cams, fuel rail, and ignition will be more than enough for your goals.
-As for the bore, i would overbore to 81.5mm to ensure a new, round bore for the new pistons. This is the largest you can overbore a stock sleeve for a boosted application.
-For gasoline, the injectors are overkill...you could use 720cc or even 880cc injectors at the largest. On gasoline, the 1000cc injectors will support over 600whp. You may have issues with rough idle if you use them...

thanks for the reply.
my block has been sleeved. is 81.5 mm still a good idea? im hearing anything bigger than 82 mm can cause traction issues. because of torque.

lol, you'll have traction issues at 400hp no mater what. i'm not to favored on the master power turbo, but that's just me. as for bore if it's sleeved and your looking for 400hp 81mm is ok but you could go 83mm for a street car and run a little less boost psi to make the same power level with better response from motor= torque. for 400hp 680cc-720cc injectors would be more than enough, 1000 is over kill. an injector closer too your hp range will give you a better idle, and better defined low load points and high load adjustment points in the map for a/f correction. stock fuel rail, ignition(good shape), and depending on cam's, stock gears will be fine. the endyne catch can is better for an all motor car, look into B & R's. their's are better suited for turbo car's. oh and last get a good tuner
