I'm lookin to do a street build I'm wanting to get 400 to 450 hp to the ground and wondering if a gt45 on a lq4 with a built 4l60e would get the job done?

It's a street vehicle

Ok Its a street vehicle and I'm not looking to peak out at 450 hp I'm wanting to have a reliable street vehicle running low boost I'm not looking for 450 on kill mode

a daily driveable 450rwhp is achievable N/a fairly easily with a mostly stock LQ4. now if you are after 750rwhp then its turbo time.
my opinion is that you are wasting your money to shoot for 450 turbo'd hp. Up your goals or stay N/a.

Ok what would a gt45 get me with 60 - 80lb injectors to small or no?

Jones618

A factory 6.0 on average puts like 235 to 265 hp down to the ground I don't think with just bolt oNs and a tune ur gonna get 450 to the ground

you seem to know it all already why are you here asking for advice?
start searching on here, youll see that a gt45 china turbo combo can do 600+rwhp easily.
I have done 440rwhp on a cam only n/a 6.0, and 580rwhp on a wild high rpm N/A 6.0.
If you decide to up your goals, your best bet is spend a few $ more on a reliable BorgWarner turbo, instead of a china gt45.

Not sayin I know it all but this is in a pick up and I have a gt45 and a 6.0l just wondering if they will match up and make for a good street motor for a 4wd

LOL, ok now that we have the whole story, Yes it will probably function fine, but list the full specs of the GT45 you have as there are many variations and not all will be happy.
Do you plan to cam the 6.0, or leave it 100% stock?

Jones618

Yes I will be putting a turbo can in it and gasket matching heads and intake and comp is 68.9/98
And wheel is 88/77.4 turbine a/r 1.05

that turbo will be fine. make certain your downpipe is 3.5 ", others will say you can run 3", but bigger is better.
keep cam very small - like 220/220, 114lsa, or smaller, and good valvesprings are important!
do NOT waste your time gasket matching anything.

Alright thanks for the advice u think 60# injectors will cut it

Jones618

And bigger is always better hints the 4Wd lol

You can make close too if not over that with Heads and Cam.
Plenty of people make 400+RWHP in 5.7 LS1's with just a cam.

ATX LSX
