how much boost does it build and how much boost can a stock motor handle.

With average amounts of fuel you'll be in the 30-40psi range with the 4000.

You shouldn't need headstuds when running that turbo. But if you have the money to do them and have a another reason to lift the valve covers off then I would have them installed.

I've never heard of anyone blowing a head gasket with the 4000, and in many cases people with A5000 turbos have ran them for a year or more above 600hp and not had issue's.

Hope that helps.

You should be fine with the a4k, the most common boost #'s that i was seen was
36-42... Headstuds wouldnt hurt anything to have them in to give a little more piece of mind, but I would say it will be just fine without them...

I never had them in, granted it hasnt been a year or anything, but I agree with Wade on this one (not like he would know anything about ATS parts though :rolleyes: ), you should be good. But if you can afford them just do it while its all apart, but not required.

I was seeing 40 PSI under full throttle. This is a pretty safe turbo for a stock motor.

Can you put studs in with the motor still in?? How hard is it to do??

I've never pulled a motor to put headstuds in, but if for some reason you feel like doing two days worth of work instead of one, by all means, have at it!!! :D

Not hard if you know what your doing. It's time consuming, but it makes for a great workout!!

Nate, You work for ats dont you? What do you sell the ats turbo kit for. Minus the turbo?[
