GPI Ported Rod Mod and Ported Throttle body questions. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Joe.G · 09-01-2022, 08:08 AM

SO I am waiting on my Ported throttle body from BO to come in, I am going to install that when I get it. Figured I would do it this way just encase there are any issues with either it could help narrow it down.

I just ordered a Ported Rod Mod intake from GPI ( Thanks Andrew ). I have going to ask Dyno Steve to touch up my tune but I have heard that its not needed and I have heard that it is, What are your thoughts?

Anyone have a step by step or tips on install? I am assuming it is pretty straight forward but figured I would ask. Torque specs?

I am going to add the Heat shield to bottom of intake as well, Figured I should while it is off.

I also ordered all new intake and TB Gaskets just for piece of mind.

It's a pretty easy install. Just the last 2 bolts for the intake you have to unscrew and lift the intake up and out. They are too long and hit the cowl to remove. I also reccomend unhooking the vacuum line to the brake booster before unbolting the intake.

I dont think you need a retune for the throttle body but probably should for the intake manifold.

Joe.G · 09-01-2022, 09:46 AM

Do I want to use any O ring lube on the intake gaskets/O rings?

CamaroDreams76 · 09-01-2022, 11:00 AM

I bought a used intake manifold off a member, sent it to Rick Crawford for his rod mod and used all the gaskets that were on it. No gasket lube or anything. Its pretty straightforward. I tried to find the link that I followed but kept getting 404 not found. The intake manifold is a 2 pass torque. 44in/lbs 1st pass then 89in/lbs 2nd pass then there's a torque sequence as well.

I had my car tuned but thats because it was FBO on a stock tune. Intake, tb, intake manifold, headers, no cats. So it definitely needed it.

Joe.G · 09-01-2022, 11:04 AM

I have an oring lube that I use when building snowmobile and ATV motors just wasn't sure if it was needed here or if there was any reason I shouldn't. I found this info on a search.

Thanks for the Link that will come in helpful.

If it helps any I ordered my GPI ported Rod mod and I waited on the Ported throttle body for now because the wait time. If Bo says you don't need a tune for the throttle body then you are good. GPI says you don't have to have a retune for the intake but that usually you should get it for the throttle body. Just fyi.

Bo White · 09-03-2022, 10:08 AM

Depending on how ragged edge the tune is currently in the car you may need some tuning for both.

Joe.G · 09-03-2022, 01:03 PM

Yes I Spoke with BO about this, I am going to have Steve touch the tune up if needed. I am going to install them one at a time to see how each changes the vehicle.

Joe.G · 09-03-2022, 06:17 PM

Does the LS3 intake have the foam pads that the LS1 and stuff had, I can't get a clear answer on Google search. If so would I add them after I put heat shield on?

Joe.G · 09-05-2022, 04:48 PM

What about the Intake Manifold cover? Not the engine cover but the One that goes over intake.

Leave it on or off?

Bee · 09-05-2022, 08:08 PM

I left my intake manifold cover on until I replaced the fuel rails/lines. I figured one less thing to trap heat...plus with the fuel lines tucked away I might as well display it.

Here's one after replacing the valve covers, before installing the fuel rails:

And here's one after the fuel rails without the intake cover:

I've also seen some people paint the intake manifold cover to match the car, which also looks good.
