That bracket serves as a rigging point for an engine lift if you wanted to pull the motor but I never used it. I prefer a proper lift plate where the valley cover goes. Just safer and more stable to lift the engine from the center point.
@@Wongguyyy If that was the case, why did they run the fuel lines in top of the transmission from behind the intake manifold? It is an engine hoist anchor point that gm had a special attachment for from the factory assembly line that would lock with the tooth on the bracket. They used it to drop the engine and transmission assembly onto the frame before the body would go on top.
Nice thinking about getting that intake and throttle body for my 02 that's the only thing I haven't upgraded on the engine. Cool decals BTW that part is called a evap purge valve.
Ive got one of the 1st ones jegs came out with on my turbo lq4 build. Im pretty sure its the same intake 100 people sell. I know the truck intake is top dog but I just couldn't get into it after I shaved the top.

which one? for the brake booster? the adapters out of the bottom of the intake came with the intake, all the other parts are linked in the description.
It would but it really is t worth the money, no noticeable gain in power. Only do it if you’re looking for the aesthetic gain! ruclips.net/video/6UhMamHU4kI/видео.html
For anybody who doesn’t know, that throttle body WILL NOT WORK on 1999-2002 DBW (Drive By Wire). The plug on the 2003-2006 is different. This one only fits 2003-2006 plug. The only way to run this intake manifold on a 1999-2002 model is use the stock DBW throttle body and the adapter plate that allows it to bolt into a 4 bolt intake manifold opening.
Don’t bother with the fab intake will lose power every where except over 6500rpm . Do a sloppy cam or a truck noris and headers . The. Hope and prey for your 4l60
Hydrolock is when the engine is locked up. So, putting a new intake on it would be like a lung transplant on a dead guy. Its not gonna make a dead guy breath better. I dont think you hydrolocked the engine, just flooded it.
Cool vid man, thanks for sharing! I recently installed BTR stage 3 on my 12 Silverado...still running factory intake though, might need one of these :)
@@CaswellCustoms I watched it, I would be bummed as well. Hoping my intake is actually a restriction given I already installed cam and headers. I hope the injector was your issue, look forward to seeing whatever you do next
Stick with that stock pickup intake or TBSS/GenVI,maybe port match w a die grinder and deburr it and smooth it out,even smooth and fill in high/low spots on the outside to look better then stick some heat reflective tape to the underside of it (runners especially) to stop heat soak(cold air iz de gooder air,makah de powah mo betta😉😁😆🤘) then you're ready to rock and roll w an intake better than any aftermarket overpriced "pretty" garbage

It was a great idea because going to 102mm does nothing on a stock motor anyway. Not to mention he needed to connect to his CAI existing tube in order to run the truck. They sell these intake/tb combos as a kit and it most typically comes default with a 102mm tb.

And the CAI was already there, so it was already connected to... something?!? It clearly has a smaller "pipe"... which is my entire point. Sure, replacing the CAI would open the thing up to its full potential. And "stock" is VERY well known to be limited BY INTAKE FLOW! But that wasn't done. There would have likely been more power gains from replacing the CAI to a 102mm style and retained the stock intake/tthrottle body because the air would move cleaner. Whats going on now is a deep/throaty grown under WOT, but little to no power increase.

It’s actually designed to pinch the fuel line during a wreck

what about the fuel pressure regulator bro please answer

Nice! Ya a Cam is the next thing on my list, how’s the drivability with the stage 3?
From Michigan too bro, nice video!

You dint have to recalibrate for that throttle body?

EVAP purge solenoid is what that "in line" piece was.
Wait did you just go from cathedral ports to rectangle ports
Are the injectors E85 compatible?

Question…
Why would you go with a 102mm throttle body and put a coupler on it that reduces the opening?
Doesn’t that defeat the purpose?
The coupler is to connect the cai to the manifold. Doesn’t reduce the inlet size
YOU'RE OBVIOUSLY NOT. A MECHANIC. 😂
Did u have to reprogram the throttle body ? Or it’s just a plug n play setup
You will need a tune.
What coupler size you use for the cold air intake on the 102mm
It’s linked in the description.
Hey bro what throttle body are u using for the install?
The one I used was linked in the description but it’s no longer available on Amazon. This is a comparable unit amzn.to/405NLV1
For the 32lbs injectors plug into the oem injector clips?
Yes they are the same plug

How are you just running a single gas line. Do you have 2
Are you using a fuel regular

Nice! Ya we all grew up in Howell and moved away in the last few years but all still in Michigan close to Howell
Will this work on a 2006 Sierra 5.3 ?
You can make it work, but the throttle body’s are differently pinned I believe.
Would this fit on a 03 4.8l Chevy

Stock engine or anything done to your truck before you added manifold ?, I have a 5,3 Silverado and looking to add some upgrades to it

What if it’s drive by wire throttle body instead of cable???

would you have hydrolocked if you kept the original intake setup on?
Most likely yes because I don’t have fender liners because of the fiberglass fenders, and my air box would have filled with water.

Many mistakes were made figured that out pretty fast
There’s no gain from a 102mm opening on a stock engine anyway. He gained nothing but lost nothing either. Its a wash
was it still reliable?
It wasn’t reliable but that was due to bad compression on a cylinder not the intake and throttle body.
