How much boost safely on this set up
I have a full bolt on 2000 Camaro with ported 799 heads and ls6 intake. 230/237 cam on 112lsa. 36 pound injectors and racetronix fuel pump. did all new top end with cam install new pushrods,lifters, and roller rocker upgrade. i imagine I'm right on the edge of what the stock bottom end can handle I'm probably around 450hp to the crank. is it possible for me to do a low boost for additional hp on a small turbo set up without having to get a forge bottom end?. Also will my compression be right with these heads?.

Your not even close to the potential of that motor. Do some research on this site on all the guys running stock bottom end ls engines. That's all I run now I have a corvette with a stock ls6 with twin 62's that made 670 to the wheels on 12 psi and meth. And my Fairmont has a stock 6.0 with 182,000 miles on it and never had the valve covers off It runs low 11's in the quarter on 14 psi on a true radial tire in a four door. So do your homework and you'll be fine the best way to learn about turbo stuff is to do it .

From my understanding the stock bottom end can handle about 600hp safely and im pretty sure I will be pushing that if I turbo or procharge. I'm asking about my compression because I want to stop detonation and I still wanna run on pump gas without having to do anything special

I'm on a regular 14psi and creeps to 16 sometimes on a stock ls1 except for cam. Besides the cam stuff engine hasn't been touched. It has 130000 miles on it also. Twin 10lb meth nozzles and running pure meth from 7psi and up. Still no issues.

Thanks this will be my first attempt at forced induction. I know my way around a motor just never went fi. When should u run meth? I don't know if I would need to or not and what goes into it. I'm looking at the rear mount sts kit right now for my turbo option

I think your a little low on you'r 600hp safety limit. I'm making 700 or so on a bone stock 5.3 bottom end with 6.0 heads and 20psi thru a 75mm s400 turbo. (e85 fuel though).

Your going to need larger injectors, I maxed out a set of 42s years ago at 520rwhp. Also that fuel pump will be at its limit just short of 600 rwhp. Meth will stretch the numbers a little depends on how much you want to run.
There are plenty of people around the 750 RWHP mark on stock bottom ends.
As far as a turbo goes get a S475, best most reliable bang for your buck, and it will have more than enough potential to turn your bottom end into shrapnel should you decide to get bored and turn it up.

My LS1 put down 641/638 through a 4L80e on e85, so I'm guessing somewhere around 750-800 at the crank. I have two GSS340 fuel pumps, 80lb injectors, aftermarket rails, and a boost referenced FPR. Tuner though I could go higher but I was fine with those numbers.

Yeah so I'm deciding against the rear mount after reading more on it. I'm trying to find a front mount turbo kit now and I'm reading up on them so I could possibly piece one together myself. I figured I would need upgraded Injectors and ill run the stock and racetronix fuel pump. Hopefully that's enough. I want to stay on pump gas so please inform me about meth kits. I'm reading up on them now but not a whole lot of info around

Ill be doing all labor myself so I will save alot and this will help me keep my budget down. Just trying to learn all I can about turbos and what kit I should buy. Pushing 400 to the wheels now and I would like 600 give or take some horse of course.

I got mine set to come on full blast at 7psi. I don't have a progressive controller so it sprays full on once it activates. It runs off a boost activated switch which can be adjusted. So it remains on standby and activates itself once it sees boost. Has a light that lets me know its on I have it mounted in my dash plus I can watch the afr on my wideband out of the corner of my eye lol. I just like to stay on the safer side even if it hurts my power a little. My afr goes to 10.3 when meth is spraying. I use vp fuels M1 which is 100% meth. Motors will surprise you how long they live if there is no detonation. My timing is 14*.
