B20VTEC GETS NEW INTAKE MANIFOLD AND THROTTLE BODY ! HSG EP. 5-49Jun 07, 2021
What's up guys, girls, ladies and gentlemen, welcome to another episode of Hunter Street Garage today. I'm going to try installing a new
manifoldand a 70 millimeter
bodyon this b20 vtec. It has a GSR head so it still has the OEM GSR aib. butterfly
manifoldI'm going to install a first chin, this comes to the intake manifold which is basically a copy of the Type R or, you know, more like a Type R, so hopefully it will give it a little more power, a little more, a little more vertigo. but this is one of the things I had to do before accelerating, if I do it I'm still letting the car cool down.
I'm going to have to drain the coolant and remove the intake manifold. And you know, it starts, so this is the GSR intake manifold. It appears to be wireless to the DA. There is a very tight fit. You're a little excited to get rid of this because I know the other collector, as it seems, flows a little better. in the upper rev range, especially the larger
body, take a look at what we have right, so here's the manifold. Basically, a first generation stone in the intake manifold could even be a block, but whatever it is now, who knows, it could be a Chinese knockoff.
As far as I know, I got this pretty much for free, so you know, I have this manifold and then the 70 millimeter throttle body that's in the corner. I'm going to try to put this here, so the main problem to deal with. with this it's just draining the coolant, the only thing that makes it annoying, otherwise it's kind of a complicated business, honestly, okay, so I'm going to remove this manifold and quickly go over what I need to do. remove the fuel rail there's about eight bolts head bolts right in front of here obviously disconnect the sensors temperature map GPS well let's get started and when you do this you're going to lose coolant and a little bit of gasoline.
I think I removed the manifold and vacuum chamber, and another part will come off with fluid dripping everywhere first, so pretty much the surface cleans up the old gas that came out, you can still see a little bit of stuff here and there, but it's I'm not going to hurt, let's go over one more time, simple, if this is what I did while subtracting to keep as many coolant lines connected. I removed the idle air control valve just so I could mount it to the intake manifold. The throttle body is simple enough that way, I had to remove the throttle body to get to the lower bolts just to be able to manipulate the tools the way needed, so anyway, this is a pretty simple procedure in the I've been at this maybe 25 30 minutes or what feels like a billion degrees in my tent right now yeah, it's been a billion degrees 93 degrees with 60% humidity feels like one or two yeah, waits a lot here anyway so I'm going to put the gasket put the intake manifold and then start putting everything else back together things like that on the fuel rail so I've got the gas zone here so a of the things they are going to take out of the other collector are the little holes for the grommet hardware, real metal, the little rubber seat I have to take them out and put them in here, which I will do shortly, so I'll go ahead and put the rest in of these, okay, okay, so we have the intake manifold bolts and this whole point has all the bolts.
Tight, I have the air temp sensor in place and plugged in so I know I didn't want to lose orientation of which plug it was. I have the air control valve around the back. I still need to place it. the throttle body and deal with this hose here now this little extra nipple here that they have on the side for the coolant. I'll have to block it because I don't need it. It is for different applications apart from that. I also need to block this because it's for the PCV system which I don't have, but I'll add one later.
This vacuum only has the fuel pressure regulator and there is one on the back. Here I am right there. I'll need to block. that's also off so you know as you move forward you can see the different sizes of the throttle body so I was going with 70k. You can see this bracket here, the GSR brackets. I removed it from this one and was going to change it. This little piece here, but it doesn't fit very well. This part you can usually swap out, but in this case I can't, so let's figure out some other situation with the throttle cable.
Yeah, okay, we've got the throttle body and how to get more. It turns on anyway, so let's turn on the throttle body. I have a nice and very stylish one, as you can see from all the cables placed there. It's temporary. I have this Golden Eagle that feels real and I'm trying to fit it in, so yeah, I'm almost there. you fill it with coolant and we start, we go and now we start it, I don't really think it has an air intake, it's the throttle body, so I'll have to figure that out here another day, but yeah, I'm just going to keep going. moving forward and just keep playing the sound just all the little details down to the manifold itself fits perfectly no problem it's just the fact that I'm using a non factory throttle body that makes me use this stock setup of the throttle cable and then yeah I need to reroute some coolant hoses, this is mostly taken care of because the GSR manifold shapes are different anyway so I'll be back in a second okay here we go.
I have one last thing to do. I need to cover up this little vacuum a little. nipple back here I have the fuel pressure regulator this is an adjustable fuel pressure regulator. I have the fuel rail bolted on. I blocked off this coolant hose and I just ran this coolant hose down to where the intake manifold is. a little bit cleaner, so now what we're going to do is connect a fuel line and you know, prime it and see if there's any leaks, if there aren't any, and try to start it up to see how it goes now, honestly, I'll probably have some problems with the idle because you know the throttle cable situation is not ideal so you know it's probably going to get it stuck here a little bit so my idle goes up and down quite a bit also I need to pour coolant into it. which I'm about to do anyway, okay, go back to editing, okay, everything clicks.
I just turned the key on to check for leaks, they don't see me, however this gauge is super weird, it's exactly what kind of fuel pressure it's going to be for. It runs, I don't smell anything, I see nothing, so I'm going to start it yet. I guess I'll have a pool so we have a full radiator system, luckily I have a spill free bucket here thanks to a subscriber who submitted. I sent it to myself a while ago and it's been one of the best things I've ever had, so thank you very much, Antonio Alvarez, yeah, what a great thing you did to Antonio Alvarez for sending me the anti-spill, so let's try to get this going. look what it does please so that it gives you like I need to tell us to eat frequently well okay now let's believe the bubbles come out and I'll take it as medicine I'll make sure there are no leaks 25 it's still What it feels like. 89 degrees outside 8 o'clock back I'm just going to leave the bubbles down, make sure there are no leaks and then we'll go drive, we're just waiting for the thermostat to open the lower radiator hose to take a little jump. your feet are already warm, the throttle response is already incredible, I mean you can hear it and the revs are very fast, the throttles get stuck opening a little bit, that's why it idles a little high because I have to get better support . obviously very hot heat comes out and it's definitely hot which ensures that all the coolant passes through the heater core which takes all the air out of the system so you can listen to the anthem for another ten minutes and see how it goes. so the system is bled, the cap is on, there are leaks that I can see of any kind, the exhaust is rattling and making a lot of noise, the heat shield is protecting me, the throttle cable is located so I'll pull it tight, the Throttle response is just amazing, this dryer. the response is really ridiculous, elastically overcome even better with a tube, you know, with the air intake tube, but I will have to get a coupler that fits the size of the throttle body, obviously in civics, four times stronger, It's much softer.
Okay, we're in first gear, here we go, it feels pretty good Shino turbo, but she's pulling the piece out, I see the Nexus, okay, so you'll notice there's an air intake tube that I'm trying, you know, four legs here, a little coupler. that I fit in there, I'm trying to make this fit, but it doesn't fit exactly where I wanted, mainly because they need it, I think it's like an LS pipe because this is a GSR pipe, so I'll figure this out a little bit later, but I just wanted to give you a little review, just give you one last look, obviously, I'm going to be, you know, making the throttle cable setup a little bit nicer and a little bit better now, as far as a review of I mean, last night I was driving it today.
I've been driving hot again. I'm happy with him. I give it the go-ahead. The power has definitely improved. It definitely increases and works well. This thing got up and moved. There was no problem before but it definitely makes the driving experience much better and you can definitely tell that the response improves with the larger throttle body anyway because thank you all for watching this, click subscribe if you haven't already you have done it, remember to follow me on Facebook.
