Ok man sorry well i want to build an ls vtec i have a 90 b18 block, and I will be purchasing a b16 head and tranny I wont to know what pistons I should use and rods and so on and what all has to be machined and what i have to do to mount it and all I want to run high 13's if possible all motor and I am just wondering what others with this build or that know about it think I should use for parts/? its going to be a slow build so i want to use the best or damn near close I heard itr pistons would be a bit more compression but i often see pr3s for good deals? so anything regarding a ls/vtec build I would like to know thanks in advanced

well if you use b16 pistons you won't have to have the rods machined to fit the pistons like as if you were using ITR's. But the ITR's have the nice coating on the skirts. I'd definately use ARP rod bolts and have the big ends of the rods resized, if you plan on using stock rods.
I'd use a 98+ oil pump (they're all the same b16/gsr/itr/b20) along with a vtec water pump and timing belt and of course ARP head studs.
If you plan on using new pistons i recommend using a slightly oversized piston and have the block bored and honed.
I'm currently building a LSvtec block myself and am using 81.50mm RS machines ITR pistons with stock rods and ARP rod bolts, i've got an ITR oil pump and ARP head studs along with a Golden Eagle sandwhich adapter oil feed setup and line/fittings for the head. But lately, the temptation of boost has really been gettin to me, and i'm tempted to sell all of the stuff i've acquired for the block and sell the fully built head i've got on my car now and would be using for the lsvtec and go turbo.
Anyways, don't forget about tuning.
If you wanna make really nice power you'll need to run bigger cams and a stronger valvetrain.

isn't there a whole bunch of info the web on the ls/vtec build.
Why not an CRVtec build instead?
Build an LS VTEC
I just skimmed over this link. It seems like its has a lot of information.

use this to decide what compression you will get...
for the money, i'd put in ctr pistons or at least JDM ITRs... roughly a 12.3:1 compression on your block and a b16 head with CTRs and i think 11.6:1 or something with the JDM ITRs... that would compliment some stage 3 cams of some sort and an aggressive valvetrain...
as zeeman said, the arp rod bolts and head studs are necessary as well as a few other things.
