LT2 Manifold & 95mm TB

BlackbeastSS2 · 10-05-2020, 07:45 AM

Installing the LT2 intake manifold & 95mm LT5 TB this week. No tune yet but will be getting one down the road.

What do you guys think the HP gains on this install? I will only be porting the opening around the TB so everything lines up. (Intake, adapter plate, TB)

I also order the corvette engine cover and will take the plate off that says Corvette. Will have to mode that plate somehow to get a decal/emblem with Camaro. I chose this cover because it has a stainless steel plate with Corvette on it and can be taken out to mode it. Maybe flip it over and change sides depending what it looks like on the other side. Wrap it and a decal possibly. Stay tuned.

Got Mine From GPI on Sunday, now the sanding cutting and shaving begins. Now how to fill the 4 holes on top?
Thanks GPI super fast shipping!

Man I wish I could make one fit on my C7, but just too tall for the Cowl.

I used epoxy and body filler. Might try one with some plastic welding next.

I thought the LT2 intake opening has to be grinded on past the oring sealing groove to match the LT5 TB opening?

Definitely you have to grind/Dremel into the green sealing ring. I will use RTV to seal the TB up.

Good info on below link on porting the throat

If you take the porting back in the throat I’d say a solid 20-25rw..2mph+

Anyone using the insulator pad under the manifold?

I am pretty sure the insulator pad is just to help reduce engine noise and no other purpose. I am not putting it back on. Weight savings!!!! Lol

Well I ported the LT2 today. Rock Auto just delivered the 95mm and Katech Adapter is also here. I will do some more hand sanding tomorrow to smooth out some nicks the dermal caused. Over all I am pumped to put it on and hopefully I am impressed with the manifold and TB. I lined it up in the throat of the manifold and I shaved off enough for the 95mm to flow with no lip from the manifold.

I just had GPI port and install the LT2 intake on my 2018. The did a street tune with all the other bolt on mods. I had the Mamo 87mm ported Tb on it.
Really feels night and day different.
Haven't tracked it yet but was running 8.0 1/8 mile before and hoping to be mid 7's now.
I think you gonna be impressed with the results !

Good to hear that you feel it’s a positive difference and I am saving my tune for later when I get everything on the car.

It’s in!!!!!!

You have to knock those bolts lose. Thanks to GPI for aligning the bottom and putting the rear connector on, the map extension made this an easy install.

Time to clean the tools and organize the garage before a drive. The idle was fine, the sound with a slight rev was different. Could be a combination of the muffler pad not on any more and of course the bigger manifold/TB.

The paper gasket at the rear sealed nicely. After drive will double check bolts, now just have to wait for the corvette engine cover which will be moded for a Camaro emblem or wait for a company to produce a sticker.

Hmmmmm, now I have a strut tower for sale. Lol

xqwisit23 · 10-08-2020, 12:12 PM

is the strut tower no where near close to fitting back on? or with some slight dremelling to the upper intake would it fit?

Not sure, waiting for me engine cover so I am probably not going to put it back on. I had thought of washers or spacers to raise it up from strut tower with longer bolts. I will test fit it for you later if your just wondering if it fits. Some other guy took a chunk out of the centre to make it fit but that really didn’t look so good.
