My apologies if this was cover earlier and I didn’t see it.
What is the ideal TB size after porting the front opening on the LT2 manifold? I don’t want to get a bigger size and not be able to match up the opening which would be a waste. I hear a lot a talk about the 95mm over the stock 87mm. That’s 0.315 inch of a difference, is there any real performance gains that can make the purchase worthwhile?

But that 1.5mph was over your stock ported manifold, right?

Anyone know what part number is or where to get the manifold bolts I snapped one off and need another. Also any tips on getting the one snapped off out?

So has anyone checked air fuel after installing the LT2 manifold (without adjusting the tune)? I saw 1 or 2 people say on the camaro 6 facebook group that it is running a little lean at wot up top. Not sure if that’s true or not but if it is, my LT2 manifold that hasn’t been installed yet is about to be for sale.

After my LT2 manifold install I never noticed any significant difference and my target AFR was still good at WOT. |

You can't just start compounding minor mods together and expect to always be fine. Stock tune and lt2 would probably be fine, the car will adjust but once you start adding throttle body, bigger intake tube, etc, things change. |

Very Nice! I order the same one and can’t wait till it’s delivered. 95mm is on.
You can put those hoses underneath TB.
