how much boost is to much on a 94 stock head gasket and bolts?

 

from what i have read on here around 50-55 with a retorqe

---AutoMerged DoublePost---

dont know how long that last though

 

I dont like seeing over 40 psi without head studs. Anything above that and you run a good risk of blowing the headgasket anything below is relativley safe

 

on my 95 i ran 40 psi maybe a little under for about a year and had no problems. the third day that i tightened up my boost elbow i saw 51psi and pop my head gasket blew. scott is right keep it under 40 psi for good reliability.

 

ok thanks for the help

 

If your gonna keep the stock turbo. i wouldnt go over 35psi.

 

What is stock boost I don't have a boost gauge yet what do they push stock

 

mines stock and im pushing 24psi. but im also running on 5 cylinders most of the time

 

what if you have head arp head bolts instead of studs can you push it over 40?

 

Usually in the 18-22psi range, depending on a few things... Auto/Man, Year, etc.

I only saw 16-17 or so before I added a boost elbow (not an adjustable one, just one with a small-calibrated orifice that came with the #0 plate.), then I saw 23ish.

I'm gonna block off the WG and see what it blows to on the stock turbo, with minor AFC mods (housing slid forward and 0 plate in the 'normal/mid' range. Was previously in FF but I wanted lower EGT's at WOT.)
