@@TheCortezChannel. I actually did the same upgrade and I was curious did your LT5 throttle body sit at a little bit of an angle towards the alternator side?
Beware truck owners this throttle body will cause idle problems that will basically be impossible to get rid of. I have 2016 6.2 E85 with full bolt ons including lt2 intake and 95mm throttle body.My tuner tried several times to correct idle but says throttle body just lets in too much air when fully closed causing computer to cause negative timing issue at idle. Aside from idle it’s running very good. There may be a slight torque loss in midrange but it pulls way harder up top. Tuner says if I swap cam than he should be able to resolve idle issues.Kinda sucks this is the case because it runs plenty good for me right now.
Really curious about your situation...there's a few things to adjust in the tune to get this working properly. I have it on my 5.3, no idle issues. Do you use hptuners?
Did you ever post the intake and if you did. Did you keep the stock gasket or just use silicone to seal it up. I'm getting redy to do this on my cammed L86?
I haven't gotten around to it yet, I've been so busy at work and juggling a new construction home too. I will buy new gaskets and maybe even throw on some silicone for good measure. Thanks for watching! Remember to SUB & LIKE! Happy New Year!
Great video as usual - would it make sense to switch out the throttle body if you don’t port the intake? Or would it be a waste or cause issues? Thanks
Yes, if I wasn't planning on port matching the intake manifold to the opening of the throttle body then having the bigger throttle body will be a waste IMO. Just port the factory l86 TB instead if you don't plan on porting the intake manifold.
@@TheCortezChannel. your buddy that is porting your intake manifold, he's just porting the manifold or, is he doing some work on the new throttle body you installed as well?
Does this make any difference with no cam or head setup? Its a nice setup and good video but im curious as to if its worth the money even when you do port and polish the manifold. Also will it help with mpg at all? And i thought you had to have a tech 2 scanner to relearn throttle body did something change in the k2xx trucks.
I'm sure the gains aren't extreme but there is some and that's what I'm shooting for. As far as mpg I'm not really worried about that. Once installed I never had any issues or any check engine light...thanks for watching!
Did you have any issues leaving the green seal behind the adapter plate Until you could get it ported? Or do you recommend removing it if you're waiting to get it ported
Hey bud, Did you have any trouble fitting in the coupler for your Air intake? I’m worried that I might need to get one that fits but not sure where to get one since I have the 5.3L. I’ll be upgrading to the ported L86 mani and the LT5 Throttle body.
Not at the moment but you do feel a slight difference. I'll be installing my Kooks headers very soon, sending my TCM to get unlocked for tuning in August. Intake manifold & throttle body have been ported already too so stay tuned and subscribe for more videos coming! 🙏🤙
Ive got a 16 Silverado, borla attack exhaust tsp long tube headers , tsp stage 2 cam and kit, intake. Appropriate to get an lt5 throttle body or more committed manifold? All comes down to the tune for sure. Any tips are appreciates.
I also have the 6.2 on my 2018 and was thinking of porting my stock throttle body - I can get the same deal as you on the throttle body b/c my cousin works for GM. Would it be better just to get this even though I won't port my intake immediately? Did you notice any gains before porting the intake? Did you have a hard time installing the rubber coupler for your intake tube with the larger throttle body?
I didn't port my IM right away and the truck still ran just fine. The coupler was a bit tighter around the TB but it went on fine after messing with it for a few minutes. The truck has been tuned already just haven't had time to edit/upload the video.
@@TheCortezChannel. okay - so no trouble with the larger throttle body blade hitting the inside of the manifold before porting. Did you feel a slight performance gain/response even before porting the manifold?
@@jewllake blade did not hit anything. I did feel the throttle response a bit better after install. Now that the truck is tuned it's a different truck now
Looking at swapping my L83 manifold for the L86, and stepping up the throttle body. I know Katech makes a 103mm, do you think 103mm is too big to port the manifold inlet to fit?

No but when it comes time to tune the truck I know they will adjust for the bigger throttle body. I just finished having it ported and port matched to the IM.
hey bro I installed a ported l86 intake manifold and ported lt5 throttle body along with a corsa Cold air intake and was wondering if you had any idle rpm issues ? if you revved the rpms in idle, did the tachometer do a irratic up and down revving once you let go of the gas? mine did and maybe it's because it needs to relearn the wider throttle body
No idle issues when I installed my LT5 TB. I did disconnect negative battery terminal before install. I also let it idle for a few minutes before revving it or driving it.
@@TheCortezChannel. installed the l86 manifold (ported) and the 95mm throttle body(ported) and the truck revs high then revs very low like it wants to shut off could it be I need a retune?
@@aj.alonzo.956 I would assume you do need a tune or they need to change things for the bigger TB as I mentioned above. Let the truck idle for a while so it can relearn itself again. Disconnect battery for 5 minutes then connect it back. Turn truck on and let it sit idling for a while.

Is it worth it porting the intake and throttle body? Ive been thinking about taking it to Reaper but idk if its worth it for my G8
Yes it is. Good for 10-15hp depending on your mods. An engine is pretty much a big air pump. More air moving in & out faster equals more power.
