Killing time..When are head bolts needed?

[serpa4]

Well, just about reached the end of the internet. Got to thinking...
If I went with an aftermarket "looking" turbo, what kind of boost does a stock LBZ take? If I run 40 lbs boost, will it need studs?
And, on that note, how involved is it to replace studs?
Will studs do the trick to hold more PSI, or is there more to it than that? I.e. will the compression be too high and start taking out rods?
I like the HP I make, could use a tad more, but doing it with less smoke/more psi would be nice.
Anyway, don't spend much time answering as I'm just wondering. Nothing happening for another year or so. Got money tagged for a new Can Am Renegade quad 1st.

You should be fine with stock head bolts at 40psi.

gt4094 will give 40-45psi and no studs needed

55 and up you are on barrowed time wiht stock head bolts

Rods hold 40 psi or is it tq/hp that bends them. I was thinking the compression with 40 psi would be hard on them.

Speaking from my experience but the HTT turbo producing 45psi of boost blew my headgaskets.

tuning plays a factor in that. Im a lot more conservative in my timing than adam. I ran that same boost for 75,000 miles and never had any problems.

I'm gonna knock on wood before my post..... ...... ...... ......

....I have been fine with over 30k miles with my A5k which hits 42lbs consistently. Mind you single LLY CP3, and ben's "conservative" timing.

I had 56,000 on mine with out a issue. but then i gen i blew the motor and not a heas gasket lol

I bet most of us are on a fine line. you play you pay.

i wish i could get mine past 30 psi

how much pw you running nick ?

3500

are you serious ? thts to much for you IMO Can you even hold rail psi with out dual cp3s.

i hold 22,000 but it will drop to 20,500-21,000 sometimes now with the the race valve, ppe fitting, and fuel rail. it will spike to 25,000 i also have an LBZ regulator.

Well I would think that a 25 degree max in timing would be pretty conservative but I guess I am wrong.
