Default lq4 turbo build

Alright so right now ive been going back and forth between what im gonna build. Currently im deployed, so ive had alot of time to think about it and i belive im gonna be going with a 1500hd, lq4 4l80e 2wd crew cab. Now with the lots of research and not knowing much about turboing a lsx i got some questions. My goals are around 700hp

My build i am planning:
lq4 stock
arp head bolts
l92 heads
ls3 or fast 102mm intake? idk yet
ls3 blower cam? any other choices that are decent?
t76 or a 88mm turbo
single or twin walbro 255 in tank pumps?
70lbs injectors? be enough?

would be doing a transgo stage 2 shift kit, with a 3200 stall and probally going with a 14bolt rear.

Now is there anything im missing or that i have absolutly messed up?

Thx matt

From what I have found you would be better off with a turbo cam, TU1, TU2 from speed inc than a blower cam for a turbo application.

I personally would go:

My build i am planning:

lq4 stock

arp head bolts (I like to do the rod bolts as well at that HP)

l92 heads (LS9 Gaksets?)

ls3 or fast 102mm intake? idk yet ( I personally would save the money and just get a LS6 Intake use the spare money for a meth kit or IC)

ls3 blower cam? any other choices that are decent? ( I went with the Bob's Brute force cam)

t76 or a 88mm turbo

single or twin walbro 255 in tank pumps? (for 700RWHP you are going to want twins)

70lbs injectors (Should be fine on pump but 80# will give you more wiggle room. I used 60#'s and wish I just bought the 80# at the time as the price difference isn't that far off verses having to sell mine and get new ones. )



If you want more items you can add I have a build thread going on if you search my "Threads Started"

Good info... I'm planning a very similar LQ4 build 317 heads with twin PT6766's. With that cam are you upgrading anything on the valvetrain..springs and pushrods?

What year is truck, and how quick do you want to go? Unless truck is a ly6 truck id go with 317 heads, and keep cam small. By going too big on Cam, heads, and turbo at 5000+ lbs things can get tricky..
