How big before head studs?

[SASKDMAX03]

Hey i was looking to upgrade my turbo but was told to do headstuds first by a couple guys, i was wondering how big of a turbo i can run on the stock bolts of an LB7? if anyone has done this let me know how big you went and what kinda numbers you are running also boost

I ran a S475 and pushed 50+ psi with no issue. Paint94979s truck has run 11s with his 475 but don't know what he's pushing psi wise. I can tell you though a monster single isn't for everyone. That's why I'm running a S464 now.

I've been looking at the industrial injection silver 62 or 64 turbo i think the 66 would be too big for me right now, anyone know anything about these they have some good deals on them for black friday 20% off so basically the whole kit for $2300

 

[Akdiesel]

Talk to Trent at EPR. Great customer service and honest guy. I personally would suggest going with the 64mm as I don't think the 62 would be worth the money. The 66mm is a tad big for some but since they both flow within a few lbs of each other I'd go with the 64

There are good deals out there on chargers this weekend. But honestly I would look into some better tuning to utilize the full potential of your stock IHI. But that's just me unless you find a deal that you can't pass up on.

i had a big set of twins with no studs, put a hole in my block and never had a HG problem.

x2 on Trent, good guy to work with. and if you go with a S4xx frame turbo you can always up grade down the road all the way up to a 80mm wheel.

I would definitely run a s4 frame not a s3. Trent is an awesome guy and has great customer service.

K thanks i'm getting an efilive tuned ecm soon i just wanted the turbo before they tune it so i dont have to get it tuned twice

Buying your turbo kit is from Trent is going to be your best option as far quality of and work and His customer service is second to none.Trust me you are going to have a ton of questions about what setup will be ideal for what your looking to do and it's nice to know that someone with real world experince is there to answer you questions.

an S466 would be an awesome turbo... if you are worried about too much boost run a wastegate and limit boost. i have seen 50psi plenty of times and no issues

Was it Dodge guys that were suggesting head studs?

LOL wouldn't surprise me the least bit

He was just the owner of a performance place, i think he drives a dodge though, he just said i shouldn't put any bigger turbo than stock without headstuds

If you had an 01 or even 02 then i would say ok... but i wouldn't worry about it now. I had a GT4094 made 38psi ungated and i made roughly 100 passes on that setup ranging from 12.3-12.1 and never a problem with head gaskets. Today I run an S475 (3.0 inducer) which is a pretty decent size single and run 11's and still no issues with head gaskets. Listen to us guys that actually run these trucks with power not a Dodge guy

Why do you say that about the 01/02?

Cuz they make way more powa


They actually had a different style head gasket that was not as good
Some people never had any issues even with them.

The gasket is superseded now

It's not the size of the turbo you need to worry about...its the actual amount of boost. You can run just about any turbo as long as you wastegate it to a reasonable pressue for your stock heads.

That's what I was thinking that they were different, I just haven't had a reason to pull mine off yet to see.

I have an 05 that has a blown HG. Stock turbo. Not sure how running more boost or bigger tunes to accommodate a bigger turbo is gonna not blow a HG. I thought the gasket type changed for the LBZ and up..... and all the 01-05 trucks have the same type.???

There are a lot of trucks out there running bigger turbos with stock head bolts and gaskets with no issues.
