stock internal boost level
I'm thinking about building a custom turbo kit, and before I get started I was just wondering what you guys who are turboed would say is a safe amount of boost for a stock engine? I'll of course install fuel stuff and it ill be tuned, but Im more interested in what the stock internals and bottom end can handle.
Thanks in advance.

And search, this has been discussed many a times:

I think he meant boost wise, not HP. But he is more than welcome to try and put 300psi into that 2AZ all day long!

Thanks for the link i searched a few times but got a bunch of random things. As for power I'm just looking to hit a steady mid-low 14. I was thinking about 8psi, but Im used to driving a mustang so over 7psi was pushing it. So I figure 8 would be a good bit of performance and be reliable from what I've read.
one more question though does anyone know how strong our blocks are? I dont see any need to stud the lower end or beef up anything but if anyone has experience opinions would be great.

im pretty sure thats why Joe asked what his goals in pwr are... that can is a factor in deciding what kind of turbo mostly like he will be using.

well im thinking generically i usually dont like to set hp goals since te goal can change a project from doing it reliably to doing it sloppy. I would rather have a 220hp car that would last 100k+ miles vs a 300hp car that will blow in 50k. It seems that 8 is a common DD psi so thats probably how i'll go and possibly a bit more at the track, I just dont wanna end up warping a head or blowing a rod sky high in a system i thought could handle more

Thank you, I don't need a lesson on turbocharging.
When you are dealing with larger numbers I agree there are more factors involved. One could assume that he is likely going with a T3/T4 setup (maybe not?) and 8lbs on stock internals with a good tune is fine for daily driving.

It matters what ur set up is going to be with the right custom kit 10psi should do I am getting mine custom made and were going to do 10psi to 11 psi and a dyno push at 15psi for turbo mag and were hopeing for 300 plus on 10 psi. The 15psi is for looks. I will post my # up as soon as the cars done it should be next week.

gt30 they picked it out for me. how much would u like to spend on a full blow turbo set up and with that power along the lines u mit want to get half shaft made and a clucth & flywheel if u want to do little things with it a walbro fuel pump to go with injectors that u get it goes for about a 120$.what kind of exst are u going to run?and also what kind of manifold. I am new to the turbo thing a love n/a but magz dont want n/a plus i want a sti killer and srt4 killer

Hell you like N/A you can make a killer set up. Go something like Independent throttle bodies, with 11.1 compression heads. Get some custom cam made. stroke it .30 over. port and polish. Stud the bottom end. Put a closer sync gear set in the transmission and add a 2 stage 150 shot of nitrous you'll be a mag worthy N/A that will eat a STI.
As for my setup. Probably going with a garrett turbo since they sponsor my SAE team already. Then exhaust will just be a generic log style manifold to a 3" dump to a high flow cat. with a flowmaster 30 series muffler and stock tale pipe. The exhaust will be 3" all the way back too. Probably going with a spearco IC and the garrett turbo has an internal waste gate. Probably a forge BOV might go with the 007 diverter valve to make it not so noticeable and give me alittle more power. pretty much decided on 8 PSI all the time though. Oh and i'm doing all custom piping with spectre piping
