need need some input, what am i missing for mods?
 

here's the specs

d16z6
zex cam
port & polished
3 angle valve job
msd coil and cap
8mm plug wires
zex plugs
cold air
light weight crank pulley
fuel press reg
chip
421 header
2 1/4 exhaust
high flow cat
obx intake manifold
gsr throttle body
50 shot nos

i want to replace my fuel filter don't know if i really need a after market one with what i am running, or stock is fine...

thinking maybe changing fuel pump too

wanna get a vafc to help tune my **** aswell

any input is appreciated

TURBO!

high compression pistons of course!!

seems like you got most of it covered tho... maybe intake manifold from a Y8... or I dunno... some TUNING!!

you would really benefit from some tuning. Since you are running a chipped p28 get it dyno tuned w/uberdata. Also get some stiffer valve springs and titaium retainers, adjustable cam gear, mill the head .020" or so for a bump in compression or get some forged rods and high compression pistons.
But make sure to get it tuned. With any sort of head work and bigger cams and especially since you have a better intake manifold and larger throttle body, tuning is key. Don't just tune it with a vafc, if you have a chipped p28 you have everything you need to run uberdata.
With similar mods on my b16 i gained about 25 whp from tuning with a vafc, i have stg 2 cams and at the time had stock intake manifold and t/b, with a crappy dc 4-1 header and 2.25" exhaust. Now that i got it breathing better with an AEBS IM, 64mm t/b, good 4-2-1 header with 2.5" collector, 2.5" exhaust w/high flow cat it pulls a lot harder. Its all about flow.
You have headwork done, so if you get stiffer valve springs your redline will raise (if you cam makes power that high), get an adjustable cam gear to dail that cam in good on the dyno. A walbro fuel pump wouldn't be a bad idea either. But if its in the budget forged rods and pistons would be nice, it would also mean new rod bearing and fresh rings so a hone would be necessary.
But at bare minimum i would say get it tuned.

Dude a chip and a 50 shot will spell disaster. Get an Ignition box and retard your timing 2 degree's when the Nitrous is activated.

Your running a 50dy shot without an upgraded fuel pump???

Good idea to get one!! definatly help out with tuning also.

some dual/tri-valve springs, TI valves.... lightened flywheel, stage 2 clutch..... LSD.......VAFC......

don't waste your money on a vafc....get ur car tuned with uberdata.

yeah high comp pistons
