I don't know if this has been commented on, but, what you are calling a pressure regulator is not a regulator on 5VZFEs. It's a pulsation damper, used to control the fuel pressure fluctuations in the rail, when an injector opens. Older Toy's had regulators, that were vacuum referenced (connected to a manifold vacuum source). The hose connection on the damper is now a vent, connected to the intake duct before the throttle plate (no vacuum, except for a bit provided by airflow moving perpendicular to an orifice, think of a booster venturi in a carb, or pickup tube in an airbrush, but in a large duct, so the vacuum signal won't be that large, remember Bernoulli ?) . It's connected upstream of the plate, mostly for emissions ( if vapor sweats through the diaphragm, it's won't vent to atmosphere because of air filter), or a ruptured diaphragm. The pressure differential across the injector nozzle, that a regulator compensated for between closed (low manifold absolute pressure), and ambient pressure with the throttle WFO, is now done by software, or PWM of the fuel pump voltage (awful way, why don't fuel pumps last as long anymore ?). If you connect a damper to a vacuum source, you now have a regulator, and the ECU has to compensate for it by closed loop fuel trimming. Dampers also use a different rate spring, than a regulator. Might not be an issue, if the trim has a wide range, but if you have a vacuum leak, low fuel volume (bad pump or fuel restriction), the computer won't be able to trim far enough, and you can get driveability problems. Most aftermarket CAIs, either weld a bung to the duct, or provide a threaded barb to connect the vent hose to the duct. My advice is to install a threaded barb fitting, sized to the the original hose ID, in the duct, and run the same size hose from the hardline on the manifold, to it. I used to see hundreds of homemade CAI's, or incorrectly installed aftermarket CAI's, done that way on a engine with a damper, when I smog tested cars in Cali. Had to fail them too.
This is why I read comments and didn't fall on deaf ears. Thanks for the knowledge. More valuable than this video that's a visual of what us boys been doing in the forums for years.👊
Speaking from having owned a 2000 model (which could be different), I would definitely do the big tundra front brake upgrade and tundra struts. Brings back memories haha.
I just installed an ISR on my 96 4runner, lifted, full armor, 33's, etc and it definitely made a difference in throttle response. Not really power, but just how quickly you get moving after hitting the gas. Absolutely a worthwhile investment.
FYI Stihl chainsaw crank case vacuum line/ hose fits the majority of Toyota vacuum points in the engine bay and you can buy it by the metre from your Stihl dealer! And it’s very good quality rubber.
I would have Hot-Glued a Bug Screen or a fine wire mesh on the inside of both orifice of the intake box to keep debris from clogging up the Air filter. All in All, it's a simple, cleaner and efficient mod. I loved it and you certainly earned my subscription. Cheers!
Deck plates when used on boats are for quick access to small storage compartments, things like ropes, spare fittings and that type of thing, when having an access lid might impact the integrity of the structure. My Dad used to sail small racing yachts.
I like the idea behind the deck-plate, and have done so on my truck. However the silencers are there to cancel resonating intake charges. Without them, my truck makes a horrible screaming noise at red line. The resonators are there to smooth air delivery, and prevent pressure waves (created when intake valves close) from traveling back up the intake and disrupting flow. Unless you modify the rest of the intake, those resonators serve a purpose to keep the engine running well in a broad spectrum of loads and RPM's, and this is especially important with heavy use of vacuum lines. For these reasons, I cannot recommend removal of the intake resonators. The deck-plate also heats up your intake a bit, so I close it up on hot summer days. Have verified with a scangauge III.
Lots of people are getting this done though. I’m looking at doing this for my 4Runner because I just supercharged it and want better sound without losing power
Again, more simple, but tasteful mods. Keep at it man. I’m sure the wife approves of you cleaning this up and making it safer, more comfortable and giving it a slightly more serious look.
@@austinniemelaHi when you moved the vacuum line from the front did you cap it off? When you removed the vacuum line from the fuel pressure regulator and went to the manifold where did the other end of that vacuum line go and did you plug that as well?
You can also cut the throttle body gasket. The factory “D” shaped gasket has part of the throttle body for no reason. You could just buy the circle gasket but it’s fine to cut.
HEY You decided to do the deck plate mod I suggested! Works really well! just remember to put it in! I didn't once and nearly flooded my engine... It really helped my rig but she was overweight with every toy imaginable. Also on the HWY I notice .5 MPG increase... not much but I drove my runner everywhere when I got it It would get 15MPG with all the upgrades... After MAF Sensor clean, Deckplate mod, and removing the yakima rack from the roof I was averaging 16-17MPG on the HWY... nothing epic but like I said she was a Overbuilt Overland Beast.

It's a good thing you used all those extensions on reassembly . Couldn't have cleared it otherwise 😏. thanks for working on this valuable content brother. Sláinte
I had a 2001 the intake is the exact same. I've done the isr mod i had to drill a hole for vacuum line in the intake pipe. Didn't notice any difference besides looking better.
Just seen your video and it looks great … just a little concerned with the pressure regulator ,the vacuum like that goes to the air intake resonator isn’t a vacuum for the regulator , since the regulator doesn’t use vacuum to operate , it’s a dump fuel to the box if it fails , but the fuel dumped need to be before the throttle body so you don’t get a runaway engine , u have it into the intake after the throttle so if it fails you will get a runaway idle
Removal of intake resonator may not have your intended effect. It's purpose is not just to decrease sound, but is a part of an engineered induction system. Plenty of info on the web. I agree it cleans up the engine bay and makes it more accessible.
I did the deck plate but didn’t like it as my filter was investing all kinds of road debris. But I’m thinking of doing the isr to an aftermarket intake hose and keeping my oem one in storage. Your link no longer works for the isr tube but I’m sure there’s gotta be forum posts about it somewhere.
Yea if you dont get that vacuum hose sealed off to that new location then it will duml fuel and send the extra through the egr and in turn put that pcv valve to good use..
yep im doing this to my 01 tacoma next week for sure ! im doing close to 400km out of a tank with 5 speed 3.4 on 31's gonna compare after the mods if i notice some change
What is that tubing at the left backside of the engine that looks like it has grey tape holding the two pieces together?? Is that supposed to look like that?
I just used the 1989 3.0l air intake piece from the throttle body to the 1997 maf. Then clamped a 3” k&n Cone straight to the maf. Bolted it to the top of one of the coil packs. Rid yourself of all that crap at once. No it likely won’t pass visual smog check but going back to stock simply means swapping the whole set up from tb to air box. What’s that a couple bolts and a clamp?
next mod, Ryobi 48v leave blower into your desk plate (cut off relay on stock intake ) on demand supercharger =P , add a injector on your alum intake pipe , with a boost switch at max pedal push , and some way to trick the other sensors , =P
This might sound really stupid, but would cracking the air box lid open create the same effect as the deckplate mod? Or at least a way to test if the deck plate mod would make a difference before spending the money? Thanks for all your videos by the way, truly a master!
This would work BUT your air filter is sealed by these two boxes being pinched on it. If you crack it open there is no way to keep your air filter where it needs to be and you will pretty much be dusting your engine

Austin, thanks for showing these 2 mods. Question regarding the ISR mod, I assume that you plugged up the original hole from the fuel pressure regulator that was connected by the vacuum hose to the silencer which you disconnected at the 6:35 mark? Because you connected a new vacuum line from the new vacuum source to the fuel pressure regulator in the back of the manifold at the 10:27 mark? Thanks

Doesn’t make sense to me how this is a cold air intake when the air is coming from the engine bay lol does that not defeat the purpose of calling it cold air intake? And then the deck plate I guess just allows more air? I’m not great with cars so it’s genuine question
