Thanks so much for the detail on cutting the foam! Made the job easier for my wife 🤣
Nice! 👌
Gotta trim off/file down the plastic on the lt2 between the ports. And it would help to port/smooth the ring at the TB on the mani too.
ICT Billet Part # 551793
FYI, there is an Adapter available with Summitt. 95mm GM TB to LT2 intake and NO PORTING NEEDED!!
the TB flap doesn't even come close to touching or running ANYTHING. & no RTV.
I was having the same fitment issues I found out what it is it's actually the ribs that go up the back side of the intake were they round out so it goes up the back towards the brake booster those little ribs need to be removed
I'm putting mine on now a little more of a pain than what I thought it would be lol For those of you putting the Corvette cover on put it on before you put the intake Or you will have to take everything apart again lol
No u dont u just have to use some elbow grease lol
@@6thglt169 If you don't mind scratching it up. Mine is color matched to the car so I didn't go the brute force route. Lol
Slick Rick, where'd u get the Vette cover? Thanks
Was going to buy a modified manifold but I think I’ll go this route and do all this myself. Great vid 👌🏾👌🏾
If the video didn't scare u... it's not that hard. And if u have the hand tools it's way cheaper to do it yourself.
@@EssMotorsports another thing, still no regrets after having speed engineering headers for a while? So many ppl talk down on them but I’m not trying to pay 1200 for headers 😂🙅🏾♂️
Modifying the LT2 on your own is probably the best bang for the buck u can do on the 6th gen platform.
@Bobby J yeah same here 1200 is a lot. And NO! Issues here I still really like my Speed Engineering Headers. I'm planning on getting thier set for my Trans Am LS swap as well.
Great video and detailed install
You Did a good Job! I like the way you did this, Got my stuff putting it on this week!
Thanks Man!
instaBlaster.
best video for 2021! THANK YOU SO MUCH
Wow Thank you! I'm really glad this video is letting people see the LT2 intake installed. It is dollar for dollar one of the best performance mods for the Camaro community!
@@EssMotorsports yeah I just got headers, xpipe, CAI,e85 kit. My tuner said to do this mod and that the results will be well worth it
Sounds like your car is going to rip!👌
Very detailed and good stuff man
Thanks! Appreciate the feedback
Oh yeh I'm doing what you did I didn't get the MSD intake because I ran out of money and the Borla exhaust that uses my dual mode exhaust costed $1500 just for the axle back kit.
For the money it is a great deal! U are not losing much compared to the msd.
Great info and awesome garage btw!
Thanks man! I spent a lot of hours finishing the garage but I'm really happy how it turned out! Not done yet tho.
Excellent and very informative video!
Thank you very much! 😁🙏
Great video thank you! You mentioned a tune near the end of the video do you have to tune once you install this manifoId?
I have to tune because I've changed a lot of parts not just the intake. The MAF sensor should pick up the extra airflow above 4000 rpm but a tune would be best to verify your a/f ratio.
Good work! Thanks for posting that!
Your welcome! 🙏
Did you use the 1/4 or 3/8 npt tap kit? Great video!!
1/4" tap kit 👍
Just got my gen 6 Camaro and of course I watch these videos.
What’s the benefit of the vette manifold over aftermarket ones designed for the Camaro setup?
Cost! I paid 180 ish bucks for mine. Almost same power as MSD just gotta do a little work to it.
Congrats on the camaro!
@@EssMotorsports thanks, I see the motivation now.
1st class video.
🙏 Thank you!
I appreciate the video, even though I had mine installed for like a year now haha. I went back to find out about foam. When I installed the Manifold I just threw out the foam. But now I hear the injectors/and HPFP like CRAZY. Definitely want to buy the foam and put it back on.
Just wondering do you hear the HPFP with that piece you cut off in the back?
With the foam I personally don't hear injectors/hpfp. I think it's the injectors that make most of the noise like a diesel. With hood close to me sounds stock.
@@EssMotorsports that’s awesome. I appreciate it! Looks like I’m ordering it today haha
I think it's worth it. It should only help with sound. GM puts it in there for a reason.
Great video my question is I got a 2017 Camaro SS with a ZL1 hood on I was wondering if it would fit how much higher does it actually sit in the engine bay thanks again for the video
My guess is if it fits under a stock ss hood it should fit the zl1 hood. Worst case is buy lt2 and if doesn't fit sell it. Especially unported it's cheap.
@@EssMotorsports how far did you go in when drilling and taping?
@@davelombardo1710 drill goes through the intake wall which is pretty thin actually. But for the tap u don't want to go in very far. Only enough to get threads started. Use the fitting to test fit/thread in. If you tap it too far in you create too big of a hole since the tap is tapered.
Great video!
Thanks!
i know you had posted "It is the 9.89mm female 90 degree. 10mm barb" but the ebay listing doesn't say 10mm barb. the closest one is "9.89 female 90 degree elbow 5/16". is this the one? thanks
Yep! That's the one
Question: At 16:20 in the video, when you did the test fit WITHOUT gaskets, was there interference? I like the idea of that fit check / inspection. I think the port flanges should sit flush without the gaskets (right?) during that test fit, otherwise you could have a leak.
That was my idea/thought as well. So in hind site I used way to much playdo. I should have made a tiny little strip like a plasti gauge. When I did the test fit with no gaskets it seemed like it was slightly hitting on the pump but its so hard to tell as with no gaskets the manifold slides around.
The gaskets i think ever so slightly raise the front and rear of the manifold since the bolts are what limit the compression. When I test fit with gaskets it seemed to sit good with no interference but the gaskets are not compressed at that point.
Either way it is very very close if not slightly touching the pump. My idle was good so I'm going to run it! 😁
Wonder if a hood pad would cut that awful engine noise..i have a 2019, i hate the rattle of what sounds like there's no oil or lifters are lose ..
Great vid! I'm guessing the LT1 gaskets would have transferred over.
Yeah the old gaskets would work. That is what I ordered was replacement LT1 gaskets. I just wanted new ones to try and make sure I didn't have any vacuum leaks.
did you realize your exhaust sound different? I felt my 2k rpm drone was gone
Someone just need to come up with a legit way to retain the factory covers
I wanna keep my factory warranty so Im gonna try my hardest to make it fit I’ll let you know
@@gorby_335is4 what happened
I installed my Lt2 manifold and now my car doesnt start:( it just clicks when i try to start, all lines are plugged back in and maf is good i have no clue
Try disconnecting battery for few minutes and retry. Make sure it's fully charged as well
Very cool.
How can I connect the pcv line because I don’t have a catch can like yours so idk how I’m going to do this ?
It's still pretty easy. U can get the 90 degree fitting for the top one. Or reuse both stock pcv line fittings and replace hose with a longer section that will reach. Go to auto parts store and match up the hose size u need.
How should I tap the back? Ive never done it before. I ordered what you have in your link.
Do I fully drill the back all the way through with the bit and then use the tap and hand tight that and take off? Then add the sealant when I install the 90 degree?
Did u order the NPT tap kit? Then u just drill the hole with drill bit provided. Then use the tap to make the threads. Don't need to tap too far in though. Use the 90 degree fitting to test fit threads.
Yes, careful to not run the tap all the way into the hole as with NPT threads it makes the hole larger the further the tap goes in. So use the fitting to test fit. And when it's threading in just right use the rtv to seal it up! 👍
@@EssMotorsports Yes I ordered everything from the link. Need to get some 3/8 fuel line. When im drilling the hole I go all the way through correct? And then with the tap to make the threads do I go in about halfway or make threads all the way through? Thank for for the response and help! Ive never done this before and Do not want to mess up.
@@EssMotorsports Also for the 90 degree is it 6AN or 8AN?
What is the exact size of the 90 degree connector you used? There are several sizes on the eBay link. Thank you in advance, and great video.
It is the
9.89 female 90 D Elbow 5/16"
Should u get another mapping for the ecu or does it also work with the „old“ mapping?🤔i already got an other mapping from the headers/coldair intake. When using the msd intake most ppl say its better if you remap the ecu
Yes, you should have the vehicle tuned which will re-map the VVE tables in the ecu.
Not too much Carbon on the valves? Do you use top end cleaners?
Valves really were not bad at all where I felt I needed to do anything. I've never used any cleaners, I bought it used. I kinda doubt the last guy did either.
it looks like your 90* fitting for the brake booster line is on the passenger's side of the intake manifold, did you have to bend or modify the stock brake booster line to get it align correctly? thanks again
Yeah the factory brake line fitting will turn to align. Then just connect with a piece of .5" rubber fuel line and clamps. This just gives some flexibility in the installation.
not sure if i missed it but can you keep using oem lt1 Throttle Body onto the new lt2 intake without porting?? direct bolt on or??
Yes it is a direct bolt on. No porting needed or adapter if you use stock oem 87mm throttle body.
Any issues on the car or anything after installing? Tune needed?
No issues, great bang for the buck. Need a tune tho.
Is it normal for your check line engine to come on?
@Carlos2sscamaro No, if u didn't unplug battery and unplugged sensors it could trip it. But the car doesn't know what manifold it is. Check what code is. Check for air leaks
@@EssMotorsports I noticed a whistle when I was step on it. Is that normal?
What do you think it could be
@Carlos2sscamaro sounds like it's related. Vacuum leak. Is the manifold ported for 95mm throttle body?
2023 NOW AVAILABLE!. NO PORTING NEEDED!
LT5 95mm TB to LT1 or LT2 Intake Manifold adapter.
Summit Racing: ICT Billet Part # 551793
TB flap opens WOT & doesnt hit ANYTHING!
at 6:04 you had mention using 3/8" fuel line with the 90* fitting for the brake booster line, but at the end of the video i see you used the stock brake booster line instead. i am assuming 3/8" fuel line doesn't work? or does it need a check valve like the stock booster line? thanks
Use fuel line 3/8 id and 1/2 od. Which I should have just said 1/2 fuel line. If you go to an autoparts store and ask for 1/2 fuel line they should get you the right stuff.
The pcv line does need a check valve. Just a straight line
Thanks for the details! Does the intake put out more noise or did you get if muffled saving the foam?
I did not notice any noise increase reusing the foam! I am really happy how it turned out. Worth the time to modify the foam.
@@EssMotorsports I trimmed my sound deadener, insulator foam too.
Nice! I saw everyone throwing it away and I was like why would you do that unless you want your engine to sound like a diesel 😆
The intake will have more Noise vs the stock (the stock one has a fiberglass style insulator around it). The foam he is talking about is protecting against the Fuel pump noise which can have a 'tik' noise to it. Definitely want to keep a fuel pump insulator as much as possible.
Anybody got a link to a good quality fitting for the brake booster hole that needs to be drilled /tapped?
My map extension won't click at the harness end and the plug come easily disconnected map sensor side clicks just fine.
If I remember right mine was same way. I filed the tab that snaps over a little so it would fit
what kind of throttle body do you recommend for this Lt2 intake ? for this camaro also what kind of catch can did you get is it good ? im sorry i just got a Lt1 and i want to make sure its good!
NP Man! Congrats! I have the 95mm throttle body from zr1. It's not a necessary mod but it adds some throttle response but very minimal if any HP. I have the mishimoto catch can which works good for a NA setup.
U gotta link for the ZR1 TB?
amzn.to/3PoDGO8
for the LT2 intake, does the hole that holds the MAP sensor have threaded bushing? the intake that i have doesn't have any. is the bolt supposed to self thread as it is screw in? thanks again
Yes the original screw was just that a screw so it just made its own threads. That is what I did
There was no brass insert on mine either
Question hope u can reply it’s been a year is it safe to not use the foam ?
O yeah totally safe. It's there for noise canceling. Maybe little bit for heat management but mainly for sound to quiet the fuel injectors and high pressure fuel pump.
@@EssMotorsports oh ya thanks for replying appreciate it and awesome gonna slap it I n today without the foam was a little concerned to put it without thanks💯‼️
@@EssMotorsports hey sorry another question! Do you have to get tuned to slap the lt2 mani on ? I just got mine but I don’t know if I have to tune it
@@anthonyavalos6363 u need to get it tuned or the car will not open throttle fully to take advantage of the added airflow.
I did this install a few weeks ago but didnt know i had to shave or remove the insulation part, so i installed it with the full insulation piece but when i installed it there was a gab but compressed it with the torque of the bolts, any risks in doing this?
Eww yeah I would not leave it like that! Take the intake back off and either remove the foam or cut it down. You could develop a vacuum leak which would make you go lean.
@@EssMotorsports Thanks for the quick reply, i will remove it and trim it, appreciate it👍
Why are the injectors noisy? it sounds like lifters to me ..i hate that noise what ever it is .
Similar to diesel engines that are direct injected which operate at much higher pressures and your hearing the injector open and closing.
Is that foam there for noise or to help prevent false knock?
It's there to help muffle the direct injector noise.
Did the old bolts come out of the manifold easily?
Yeah no issue taking them out. Relatively low miles and car was not driven in winter/salt
Do you have the c8 cover? If so will it fit with the map extinction wire being where it is
I do not have the cover or plan on getting one. I like the look without it. On the forums sounds like there might be some hood clearance issues. Minor but none the less
What’s the torque spec for the bolts that tighten the manifold
89 inch/lbs
Is there any reliability issues with lt2 mani?
If it's installed properly and shaved down for the hpfp, then no issues whatsoever
Are u sure the link is to buy the lt2 intake manifold? It takes me on rockauto but it doesn’t say lt2 manifold or a picture of the intake manifold ?
Yep it's part number 12697714. If you Google that part number it's right. Once u add it to cart it show part number. It's cheap right now too!
@@EssMotorsports ok thank u I received my lt2 manifold and just ordered a mishimoto oil catch can, do u need that part that u mentioned to put my oil catch can on or it’s not needed?
The 90 degree fitting is not Necessary but makes it cleaner. Otherwise just clamp the hose directly to the lt2 fitting.
@@EssMotorsports ok thank u so much
did you use a 95mm tb or just the stock one?
I used the 95mm Zr1 tb, I have a video on that install as well. Check it out!
I ordered the tap kit you have the link for thats the right one right
Sure is! Worked good and you don't have to run all over town to find it.
@@EssMotorsports thank you so much for all your help maybe you could just install it for lil
Me lol
hello sorry to do all that work the battery is disconnected
How do you remove brake booster line ?
U have to push the red lock ring inwards while pulling hose out.
I found this adapter on Amazon would this work?
Fuel Line Quick Connector 5/16 Bundy Female to Barb for 6mm ID Nylon Tubing Elbow 90 Degree for 5/16 Steel to 1/4 Nylon Tube, Pack of 2
Copy and paste that and it will come up in Amazon
It looks like the quick disconnect part is 5/16 and not 10mm. It needs to be spot on at 10mm or it doesn't fit. Ask me how I know. I went through a couple iterations.
Use my link for ebay and select the 9.89 90 fitting. Its like 4 bucks and it comes fast in the mail.
@@EssMotorsports ok cool thanks bro!
@@EssMotorsports there's three different 9.89s which one sorry to keep bothering you i just want to make sure I got all the right stuff
the hole that you had to drill and tap for the brake booster line, how thick is the manifold wall in that area? thanks
It's super thin. Probably .100" thick. That is why used rtv around the fitting as the threads alone are not going to seal well
@@EssMotorsports thanks for the all info
How did you take out the brake booster line? Do you literally just pull it out?
The red tab on the fitting need to be pressed in with a screwdriver and pull out at the same time. Then it should slide out
Awesome, thanks so much man!
Anyway to keep the original cover?
No the original LT1 cover is not gonna work.
Where do you get the parts needed to install it bro ??
Rockauto and Amazon where else! Haha. Links are in the description for the parts u need. Rockauto is usually the cheapest for the LT2 manifold.
What are the specific torque measures for the intake bolts?
75 in-lbs
How long did it take you to complete the job?
If I wasn't filming it would only take couple hours. I'm picky so I take my time! 😂
Thanks for the info.
I am the same way so I can count on a couple of hours then.
One more question and I will leave you alone. Did you feel it in the seat(noticable difference)after the manifold swap?
@@ChicagoNative71 I did all my bolt ons over winter so didn't just do the manifold.
Any issues hitting the LT4 fuel pump?
I have the normal lt1 pump. I don't thinkvi would run the lt4 pump with the lt2 intake. It's that close
Oh, guess I'll have to find something out lol
Saludos muy buen video podrias poner los part number de todas las piesas gracias
All the part numbers are in the description that I used with the links where I bought them from. 👍
What size are the bolts in the intake manifold and how do you take off the boost line?
I don't know what the bolt size is but you just reuse the bolts from the original LT1 manifold. If your talking about the brake booster line it's easier to disconnect the line further upstream. Follow line to next connection. The brake booster line is a push to connect. So you have to push the outer flange in while pulling hose out.
@@EssMotorsports also do you need the cover under the manifold or is that just a choice?
@@carlosrivas3985 the foam is just your choice. Easier to just leave it out, just might have more injector noise.
What fitting did you use again for the back side of the manifold?
www.amazon.com/gp/aw/d/B07B942MLV?psc=1&ref=ppx_pop_mob_b_asin_title
@@EssMotorsports thanks brotha !💪🏼💯
Does it need to be tuned after?
Yes it should be tuned after
Torque spec of the throttlebody?
89 in/lbs
How much HP would you get from this?
From a stock LT1 unported manifold u can pick up 15ish HP. Which for the money is really good!
How did you take out the map sensor??
There should be a screw you remove and then it can be popped out.
U think this will void the warranty is it reversible
It would more than likely void warranty. But it's easy to swap the original back on if vehicle needs to be taken in for service.
@@EssMotorsports yea thats what i wanna do before i go in for matienence thanks for the answer
What size hose off the 90 connector
Mine was with the Misimoto catch can, but .375 ID and .5 OD hose is what it is if your doing custom.
So how does this Intake do against the msd atomic?
Gets you 90% of the HP at 1/6 of the price.
@@EssMotorsports ah, I see, so me msd atomic is better?
If u have an MSD, then yeah I would keep the MSD. Has larger throttle opening
How’d you connect the brake booster
It's in the video. I drill and tap back of manifold. Then connected with hose
@@EssMotorsports what hose did you use. I’m having trouble find the size
@@4kjaimee I believe it was just 1/2 od hose. 3/8 id
Looking at your channel we are going g to have the same build just about
Nice! Car should be a totally different beast this summer! Sounds like your going to have fun as well!
Part number extension sensor? pliis
Link for ICT Billet extension is in the description. 👍
Tnks
What's the part number for catch can 90 he used?
It is the 9.89 female 90 D Elbow 5/16" quick connect ebay link in the description 👍
@@EssMotorsports thanks
What size is the 90 degree hose connector??
It is the 9.89mm female 90 degree. 10mm barb
Thank you 🙌 i just ordered mine for my 19 2ss
Does this require a tune?
Yes u want a tune to take advantage of the added airflow provided by the intake.
@@EssMotorsports but if I didn’t tune, would I still see some gains? Would I have a check engine light?
@@ClutchKillers with the Gen V vehicles they are torque based system and only make the torque that is requested. So with stock values/un-tuned it will more than likely close the throttle to only make stock torque. So there will be min gains if untuned.
What did you use to cut the foam?
I have an exacto knife that the blade extends. But a normal exacto knife would work good. Something really sharp
Sounds good! Thanks! Also that 90° fitting doesn’t fit my catch can hose, it’s too small. I got the same fitting as you, how did you get it to fit?
@Cembruh Humm do u have the Mistimoto catch can as well? I didn't do anything special. It just fit.
@@EssMotorsports I see, I might have to get a different hose. I have one that looks identical. Also Want to say thanks for the help with your headers video and LT2 video. Really helped me out this past weekend. Car is finally tuned and made 496 wheel HP.
@@Cembruh holy crap! Those are good numbers!
Do you have to tune it after ??
@@ssvance.in4k yes
@@EssMotorsports ahhh okay cuz i had the check light on and than it idles in higher rpms than normal and driving it feels uncomfortable the gears feel off and it gets super hot
@@ssvance.in4k that's more issues than a tune is going to fix. Sounds like u have a vacuum leak somewhere
@@EssMotorsports damnn cuz i had none before i didnt know they can cause that thanks for the information i was hoping a tune would take it all out
@@EssMotorsports one of the gaskets actually broke off am i supposed to put something with it ?
The msd and lt2 maje the same power. The msd actually makes more uptop its just expensive.
Expensive being the main word. Lt2 is good for people that aren't racing and drive on the street.
Can I install the lt2 intake manifold on my 2018 camaro 2ss without tunning it?
U need a tune to take advantage of the extra airflow or the car just limits itself to stock power levels. It only wants to make a given amount of torque stock and the tuning tells it to make more and open the throttle all the way. #torquemanagment
@@EssMotorsports how much would a tune cost for that purpose ?
A tune is going to cost the same regardless if u just have one bolt on or a couple. I'd check out Pray performance and GPI as they seem like leaders on this platform.
@@EssMotorsports but would it still run smooth without the tune if I plan to tune it later?
Yes will still run fine, but doing it blind not knowing air fuel ratio and what the engine is doing, etc
Do u need a tune with this?
Yes otherwise car will just close throttle from the extra airflow and limit itself.
@@EssMotorsports what’s the best performance mod that doesn’t require tuning. Just starting to mod my 2019 ss
Rotofab intake is probably the easiest to install. A 174 degree thermostat is cheap and keeps u out of knock which helps a lot. Lt2 intake will pick up almost the most hp but without a tune it might only pickup a few. Checkout my Playlist for the thermostat and rotofab. In the end it needs a tune to allow the car to open the throttle all the way. The car is smart and limits itself to little over factory power without a tune.
@@EssMotorsports thank u I will look into it
@@EssMotorsports I plan on tuning it eventually just trying to not spend a ton of money rn
Wish you copied that foam pattern for feature users ..you know made a mold for that patten. That would of been a seller .
Everyone has the foam under intake stock. So if you copied what I did in the video and cut around the HPFP then your good to go!
Love the 1LE......subscribed :)
Thanks man!
Im betting that you didn't feel any gains from that swap.
If that's what u want to think... sure
@EssMotorsports Intake alone won't produce any seat of the pants gains unless you put more air in and more air out. I have a 5th gen Z28 and am quite aware of bolt on gains. Put a Fast 102 intake and some long tube headers, and you're in business
Did you keep the foam or fix it to fit under the manifold ?
I cut the foam to fit the new manifold. Doing so my opinion there was no noticeable noise increase of injector noise.
@@EssMotorsports what part you cut , i saw in some isntalls it was higher in the rear? some just didnt use any
Yeah cut the back top portion off. And I trimmed the intake in-between the intake ports to clear form.
18:45 in the video I explain and show where I cut
@@EssMotorsports thanks if you happen to have a picture or reference please trini.s2k@gmail.com not a mechanic i kinda diy lol until i need help and call friends would thanks in advance
What type of throttle body do you ?
I actually just released a new video where I discuss and install the LT5 95mm TB. Check it out!
