5.3 Turbo HELP! Hey guys,
building a turbo 5.3, Motor is on stock internals, ARP studded mains and heads, and ARP rod bolts. Running a LS6 cam and currently has 243 heads. Edelbrock Victor manifold with elbow and 90mm throttle body. I am looking to build a fun cruiser, 91 octane, not a full on race car. I have a set of 317s I can swap if that would be better.
So here the thing, I called Jose and Force inductions and he recommended a Borg Warner s366. I ordered it and now that I'm ready to finish fab, people are telling me it too small and I'm gonna lift a head because of too much back pressure.
Need help, Is this turbo going to ok or should I try to get my hand on a S400? Again, a cruiser that's got ***** when needed, lol.
Thanks in advance for the advice

Listen to others all you want but you done spoke to Jose, that's all you needed to hear. He has probably forgotten more about turbos than most of these "other" people ever will know.
Their was another thread in here somewhere that had a s366 on a 4.8. Seemed like it done really well.

Yup x3 Jose knows his ****. One minor detail.....you forgot to tell us your power goals and what it will be used for. The S366 can be configured in many ways so to say an "s366" is too small is not enough. Need more specs on the specific s366 you are referring too.

and thanks guys... All reassuring info.
Any suggestions on injector size? Running an A1000 with boost by reference regulator.
I'm leaning towards 60# @ 43 psi, but any other suggestions? Just planning on running 91 octane.
thanks

yeah, had to replace all the hardware cuz of GMs stupid torque to yield bolts, so I figured why buy now and later, so spend a little extra then ... I figured when it blows, I won't have to spend all the money on the hardware, just swap it to the new block. next block will have forged internals and be run on more boost

The only true TTY "one time use" hardware are the head bolts. Per the GM FRM it even states the main and rod bolts are re-usable. Don't confuse TTA with TTY. Installing ARP hardware on the factory rods is not a good practice in general. There is a chance you can EGG the rod ends. Many do it with success, some aren't so lucky. An ARP tech will tell you the same thing. Factory hardware will far exceed your power goals and will easily support 900+crank HP.
Just gonna cross my fingers and hope for the best. I have a LQ4 short block I can throw in there is the 5.3 gives, lol.
Thanks for the help

I would assumed for boosted applications ARP would be the way to go on the cylinder heads correct?

Great info!! With the head bolts being TTY, would it be a good idea to go ahead with APR bolts/studs? or should the stock components with stock hardware statement be followed?
