I am planning on an APS kit on my stock LS1 engine. At this piont i'm on a tight budget after the kit it's self. So if i run abou 4-5 PSI what supporting mods are must have?

I have the BMR K-Member already.

I am planning a forged Iron block later on.

Thanks!

Lots of people run stock long block turbo builds. Just make sure you have plenty of fuel and a good tune.

forgot to add I have HP tuners and am getting a wide band, have some help and plan to keep the tune conservative.

I've seen a lot of guys do springs etc. will i need it at minimum boost levels like i'm talking? stock injectors SHOULD hold out if not then that will have to be upgraded of course.

You will likely need mininum 42 pound injectors but really 60s should be installed for safety. To run 4 or so psi you will have to buy lower psi springs the aps kit comes with like 7.5 psi springs.
You should also install a better intank pump they are pretty affordable.
One local guy does run like 5psi on his sts kit with stock pump but 42 pound injectors,tuned with hptuners.Key to stock block survival is to stay conservative on tuning in terms of afr and timing. Stock pistons will not survive if you screw up on the tune. And running lean from stock pump or injectors will also do the damage.
A pump is a few hundred bucks and 42 pound injectors are pretty cheap especially used.
Course you should also change out to colder plugs.

So that is about it for support mods. Wideband of course is a good thing to have and boost gauge. Boost controller is not that necessar if you are running low boost like 4 or 5. The boost controller will not let you run boost lower than your minimum gate spring boost pressure. So you can not turn down the aps kit to 4psi with a controller you have to swap out the springs in the gates.

At low boost you should be fine with pump gas ,buy premium of course. Remember stock compression is 10 to 1 ? So again reason to be reasonable with timing and afr.
An alc injection system can also give you some exta safety on pump gas.

Thanks... I already have just about everything modded. Mainly just wanted to know how the fuel system requirements, and other little crap I had not thought of for "just" the turbo. Suspension is taken care of.

I have a bone stock engine. I upgraded the fuel pump (racetronix), injectors to 60lb injectors, valve springs (LS6) and hardened pushrods. Got a safe tune and put over 15k on the kit since it was installed in fall of 07'. Been reliable and a lot of fun.

I am at the stock 7psi springs that came on the kit. I made 508rwhp / 513rwtq.
