I went with the gt45 from dna, thanks for the advice and the links, I was curious if there was much difference between the intakes with boost. On the injectors 80 won't be to big?

Some 60lbs could have done more than good. Unless you want to run E85 which I couldnt see it in the thread. Lol

I think you'll be happy with the dna motoring GT45. It will spool up quickly for you and is a good entry level "bargain" turbo.

As for the injectors, the 60's will carry you to the edge of your goal, but the Siemens 80's will give you room to grow and are tuner friendly (high fidelity). If you follow any of denmah's builds, that is what he uses:

"i use 80lb siemens deka injectors in every car i build, great tunability stock ecu and megasquirt, flexible, large and most cost effective at 330 shipped usually" ~denmah.

The rule of thumb is 10x injector size = rwhp. So 60 are good for 600 (Safely). 80's are good for 800 rwhp (Safely).

Boost is soooo addictive and when you get to 600 rwhp you'll be pissed that you cant crank it up 5 more psi because you bought undersized injectors. You'll think "I can sell these 60's and get 80's". Nobody will buy your used 60's and you'll be out another $300-400 just to dial up 5 more psi.

They are going to cost you the same right now (and perform the same up to 600 rwhp), just get the 80's and you won't have to ever worry about being on the edge of safe (running lean... boom).

Trust me, it's like going with a TH400 instead of a TH350. The TH350 will get you to your current goal, but when you want to up the boost a little bit more, as we all eventually do, you'll be glad you have the TH400 in the car instead of the TH350. Think of it along those lines... whenever you can overbuild something for nearly the same price, do it. It also gives you room to play with E85 eventually. Same thing with the F90000267 fuel pump, if you think their's a remote chance that you want to try E85, get that over the 90000262 pump. It'll be better for you in the long run and doesn't hurt anything right now.

Again... you'll thank me later for these words of advice on the injectors.

Also, side note, remember EV6 connectors when using truck harness (LM7 engine, etc), EV1 connectors when using car harness (Camaro/Firebird, LS1, etc).

With the ev6 and ev1 are u referring to the dfferent plugs used for injectors

I don't think the truck harness is ev6

savageboy69

so im looking at head studs and i see 2 length 3 length and same length, i have a 04 5.3, i pulled a bolt from inside the valve cover and one outside by the spark plugs and they were the same, are these the bolts im comparing? sorry if this question seems dumb

HRHohio

Actually, I think you're right... I'm getting myself confused crossing platforms here. I think they are taller though...maybe that's what I'm thinking.. I'm getting myself confused now... now I have to go and check for myself.

Good catch!

HRHohio

Maybe it's LS2/LS3 use the EV6 style connectors and the LS1/LM7 etc use the EV1 style.

Fuel injector guru's please chime in...

ls2/ls3 uses ev6
ls2/ls6 uses ev1
lm7/5.3 truck uses mini Delphi (I think that's what it is called)

ls2 intake use short injectors
ls1/ls6 intake use tall injectors

HRHohio

No wonder I was confused. SHEESH! LOL!

savageboy69

got a ls1 intake from a buddy so this build is slowly chugging along, still looking for 80lb injectors, valve springs, and i need to get some accesory brackets (alternator and power steering) from a car, probably a cam too

astross89

I heard good things about bt springs. right price for everything. maybe someone else can chime in.

ill check em out thanks, got a little done on the hotside, not sure if im gonna do mid mount or mount it on the passenger side, wating for the turbo and motor mounts to get here so i can set it in the car, looks like the pipe is gonna be very close to the steering box

savageboy69

ok so heres my dilema, does anyone know if and how its possible to merge 2 straight pipes (side by side) into a turbo flange, id like to keep my layout and turbo location as it is in the pictures but i cant figure out how to get 2 straight pipes into my turbo flange, im open to any and all suggestions

be good

i just did one at my shop, blower, heads, cam, headers... put down 600hp. not bad for a little pick up.

savageboy69

so i finally got this figured out well somewhat, heres what i came up with, problem is i cant use the c5 accesory bracket i just got, so im hoping a camaro alternator bracket will work, so if anyone wants to trade a c5 bracket for a camaro one let me know lol

savageboy69

another lesson learned, when u fab up piping make sure u have everything on your motor so u dont have any suprises lol. round 3 of turbo piping will start soon. found out i actually just need the stock 5.3 alt/ps bracket so if anyone has one to get rid of or wants to trade for a c5 bracket let me know. headstuds and bov finally showed up

savageboy69

ive made a little bit of progress, wedding is this saturday so progress has kinda been null lol, got my v bands on my truck manifolds, and found a line on some injectors

savageboy69

so i got a set of injectors here and ive found about 4 different lbs ratings at the same psi depending on the company that sells them, is there anyway short of testing them to find out for sure what they are . numbers on it are
0280158117
7-01-05-10-002621
then above the nozzle 81187

I've got a stock truck alt/ps bracket that still has the ps pump mounted on it if your still needing one. Shoot me a PM if you do.
