Skunk2 Intake Manifold & Throttle Body - How To Install - B20/B18 Civic EF

Skunk2 Intake Manifold I bought - amzn.to/2DqJuW6
Skunk2 Throttle Body also - amzn.to/2Dq3V5h
In this video I am removing the OEM intake manifold & throttle body off of my 1990 Civic DX hatchback and replacing them with the Skunk2 Alpha Series Intake Manifold and Throttle Body. The car has been converted from DPFI to MPFI already and has a JDM B20B swap running OBD0 using the 90-93 Integra components. This will be a complete walk-through on how to install the parts onto the engine.

[@kooksgarage3301]

Sweet! Looks real nice

[@MooZleZ]

awesome video again, even when I already know how to do everything it's just relaxing to me to watch you do it :D btw don't forget to mention that you have to torque the intake manifold to engine bolts/nuts in the correct order for anyone trying to do this for themselves, otherwise they'll get huge vacuum leaks :p

[@GarageBuiltHondas]

falZ good tip, unfortunately I don't follow it with these Hondata gaskets. I only torqued them at 17 ft lbs, then double checked them.

[@MooZleZ]

Jon Widmer so you just did them in a random order ? I used a hondata gasket with an edelbrock performerX intake and I had to torque them in the correct order/pattern or else it had a big vacuum leak

[@GarageBuiltHondas]

falZ wow, that sucks. I always start from the center nut/bolt in between the 2nd and 3rd runner then work my way out til I reach the ends. I've had great results doing it this way. I even did the MPFI manifold on my d15 on the wagon with an or gasket and it's been great. What is the torque sequence?

[@MooZleZ]

Jon Widmer haha, that actually is the sequence, from inside to outside, thats why you never had the problem. first time I did it was on a 1999 integra type R and there was such lilited space to reach everything so I torqued them on reachable basis :p had to redo it from the inside outwards :D

[@GarageBuiltHondas]

falZ aw perfect! lol. I probably knew it from doing so many over the years that it just became habit. I need to remind myself to include these small bits in the video sometimes because I forget not everyone has been playing with the cars like we have, some are virgins popping the automotive cherry!!

[@GarageBuiltHondas]

Not a difficult install, the video seemed long after I finished it, but only took a few hours in the afternoon.

[@kracksmith4ejm1]

did you have to do any fine tuning to IVAC idle adjustment or Throttle body adjustments?

[@GarageBuiltHondas]

None so far. The idle air adjustment screw was all the way in so I couldn't use that to lower the idle. After finishing up all the vacuum lines (new line from booster to manifold, and from manifold to charcoal canister) it idle lower. After it reaches operating temp I was getting a 900-1000 idle. Lastly, I'm going to tinker with the IACV gasket as mine seemed flat so maybe that shall help. I haven't adjusted the cable or the stop on the throttle plate yet. It had got to be something simple, I have the same intake manifold on my Si with the B16 and it idles like a champ. We'll see how it goes!

[@bobthompson4319]

When putting on the shock tower bar you should Jack up the car from the front center and adjust it so it is pushing on both towers so when turning it pushes down on the other side and actually does something. Just a tip hope it helps.

Hey man, been watching your video for a while now. I have a 1990 Honda Civic Hatchback EF and I need to find upper control arms for the front that are adjustable because my alignment shop says I need them cause the current ones I have are non-adjustable. Can you help a bro out?

[@housealan334]

Nice!

[@johnnyo3fan]

Just re-watched this video because I have basically the same setup on my 90 hatch with a ZC swap. I also had a high idle that turned out to be a vacuum leak (I put the throttle body gasket in upside down). I was wondering if you ever got the idle down and where you ended up setting your fuel pressure and the air idle screw. Thanks again for the great videos.

[@GarageBuiltHondas]

All idle screws will be set differently. Adjust til you see fit. I left my pressure at 42.

[@mark0shark0]

[@Pengquian]

Does your car have the evap system in it still? I have no idea where to run the lines from the evap canister. Help please!?

[@elileon2043]

Awesome Video. Thx for all the help not just this particular video but all your work. Just a question. Did you use your original throttle cable? I’m having issues with idle. My car won’t start unless I’m holding the throttle down and maybe after a minute the car will stay on but idle super low. My ef runs great once I’m on the road but any stop it revs low again. I tighten my cable and still starts low at a cold start but once it warms up now at stops it idles way high. I’m stumped. I have the same swap. Everything’s been replaced just never removed the tps which is still oem with the rivets.

[@GarageBuiltHondas]

Try adjusting the throttle plate stopper screw. Maybe even the idle adjustment screw. Both are on the TB.

[@thedustyradio]

I just wanted to check and ask, the injectors other manifold bits you were using on this setup were for a b18a1 or b1 right. I'm getting a b20 this weekend that comes with a skunk2 mani/tb and an aem fuel rail that has no injectors or anything on it so I'm starting from scratch finding parts for them lol

[@BLAZEPSI]

Love the Vids! is the TB and INTAKE worth it for daily? Did it have a noticeable torque on a stop. Thanks....

[@GarageBuiltHondas]

Thanks! It did feel a little stronger. The b20 is so torquey already that it was hard to tell though but this car moves pretty darn well now!

[@johnnyo3fan]

Hey Jon, thanks to your videos I was able to swap out the 1.5L DPFI in my 90 hatchback for a ZC 1.6L. I've been thinking about getting a Skunk2 set up for it, but I have a question. Don't you need to switch out the injectors to match the increased airflow?

[@GarageBuiltHondas]

Excellent! No, the stock injectors flow more than enough for just an intake manifold.

[@Thefranchizeek3]

Hey wat did u use to hold that spark plug cover in place. I made a plate havnt figured out how to mount it

[@GarageBuiltHondas]

It came with mounting hardware. I didn't make it, I purchased it off of eBay.

[@roelpastors9588]

Awesome vid!! So are you going to dyno it? curious as to how the power curves look. I want it on my B20 but kinda scared I'll lose too much low-end torque. Running the stock b20z mani now.

[@GarageBuiltHondas]

Roel Pastors man, it feels hella strong! My butt-dyno loves it! lol. The motor has a lot of torque to begin with, if I lost a little but gained top end, it's worth it. It has more than needed, some top end will help me out when I take this car to the track .

[@GarageBuiltHondas]

Roel Pastors I'd like to dyno it again, we'll see if I have some extra cash next month!

[@roelpastors9588]

Yeah you'll probably gain more on top than lose down low. But I kinda made a challenge/sport out of it to create a motor with super great low-end :) When I finish the EJ B20 coupe I'm thinking of getting an EF as second car.If you do a dyno a vid would be so great.

[@GarageBuiltHondas]

CarsNfish Thanks man, I love the b20. I've been playing with this one for about 15 months now and it's a great engine. My "butt dyno" tells me I gained some top end at the track. It definitely feels like it at WOT also. I will get it dyno'd again once I get the header I want plus a test pipe installed. With that setup that I had before the IM/TB install it made 136 whp at 3800 ft elevation.

[@CarsNfish]

Jon Widmer yea ok I'm thinking of installing it on my b18a1 it's a 93 da it was an auto when i got it but i converted it to 5 speed so the manifold has a bunch of junk

[@GarageBuiltHondas]

Makes sense, also have a nice bump in power too.

[@notone4029]

Love your videos . Now to each their own but after a bad sticking throttle blade and numerous other build flaws with Skunk 2 parts. I thoroughly hate the company and the parts. K tuned only for me. Just curious how the throttle body from skunk2 was fairing on your build?

[@GarageBuiltHondas]

I haven't had an issue at all. I recently put the same throttle body on my Si and that one has been fine too. I'll have to research the sticking throttle plate, I haven't read about it. I wonder if adjusting the throttle plate stop on the front would help the sticking issue?

[@808Deathmetal]

Hey jon, I'm getting mixed reviews on calibrating the tps sensor. People say to warm up the car first, then test the TPS. Everytime I've tried to calibrate my tps I get .5 closed and 3.5 to 3.6 WOT. I checked the voltage on the middle wire, all was good. checked my ground wire, all is good. I've tried like 3 different tps sensors and they all do the same thing.

[@Coda5610]

Braden skunk2 has a full video about that, they calibrate it on the bench

[@808Deathmetal]

Its not with anything skunk2. I have an 89 integra, all oem. It's auto, ( im doing a swap to 5speed soon, but the tps not being calibrated correctly causes all sorts of shifting and rpm issues. I want it gone. I want to figure it out today if possiblen

[@GarageBuiltHondas]

So at WOT you can't get anywhere close to 4.5?

[@808Deathmetal]

Nope. Not at all. Im going try again today. I will tear the wire housing so i can see if i get a better reading. I'm going to bet that's what my issue is.

[@808Deathmetal]

I got up to 4.3. Car shifts way better now. At least I'm on the right track. Loosened and re positioned the throttle cables on both the pedal and auto trans. Messing with the auto trans shifter cable really helped. I messed with both of them and got a happy medium. Gonna mess with it some more to see if I can get 4.5 at WOT

[@shawnlessieur682]

[@isaacangulo2697]

What size is the custom hoses? 5/16?

[@isaacrogers16]

Hey a couple questions, I'm running this intake manifold on my b18. I've watched your video probably 50 times. I'm stuck at where to run my hose from my charcoal canister. Do I run it to the top of the throttle body or to the far back of the manifold? Also I don't have a second coooant hose that comes from the thermal housing to the manifold. Is it okay to only hook up the bigger inlet and leave the smaller inlet line open?? Thanks for making videos!!

[@GarageBuiltHondas]

The very top smaller one goes to the manifold or TB, doesn't matter just needs to read vacuum. The larger one goes to the large nipple on the TB.

[@MegaDankone]

Question sir: where does your little hose from the water pipe on the back of the motor connect to? Mine goes from the water pipe to the iacv, I'm just wondering where yours goes with the way you ran your iacv water hose straight to the water neck under dizzy. Did you cap that water pipe line off?

[@GarageBuiltHondas]

MegaDankone The hose nipple under the dizzy went to the TB, then out that back of the TB to the IACV. I just eliminated it running through the TB, I didn't want it to heat up the TB any more, I'm trying to keep it as cool as possible.

One of the best channels on youtube. Tried to do my front springs on my lude with your video, turns out the lude sh has a sway bar in the way of the 17mm bolt at he bottom fork. Will need a hoist :(

[@GarageBuiltHondas]

Matteo Coutant Really? It wasn't like how the sway bar was attached in my video? The radius rod does block the bolt at the bottom of the fork but you can remove it if the bolt was put in the wrong way.

[@matteocoutant4282]

Garage Built Hondas yeah, I’m pretty sure it was in the wrong direction, the bolt was too long to pull out of the fork. What’d you do exactly?

+Matteo Coutant Hopefully if it turns into a job you don't get sick of working on your own car. It happened to two of my really good friends, but sometimes it just works out that way.

[@freakyflirt420ful]

Do you have to depressurize the fuel system before doing any intake manifold work?

[@GarageBuiltHondas]

+Blaze Dela-Cruz You can loosen the cap and then when you remove the fuel line there will only be a slight spray, it's never much especially if the car has been sitting s while before working on it.

[@dat1song410]

Ok for the big question any gains in power besides it looking nice?

[@GarageBuiltHondas]

Dat 1 Song Some in a pretty low HP setup such as mine, but it's needed if you want to continue to gain power with an opened up exhaust system/header combo and future tuning and/or cam upgrades. With what I added, maybe 4-9 HP hopefully!!

[@tomarun6624]

I bought an eBay 74mm throttle body and it doesn't have the coolant lines and the top doesn't have the nipple for the evap. How do i run the iacv lines and that evap?

[@GarageBuiltHondas]

You can run the IACV lines to wherever. As long as all coolant lines are used up, you csm even T some if you need to. No idea on the evap if there isn't a port for it.

[@keenanwalker1313]

Hey Jon, excellent video man really enjoyed it. I have a USDM B20B motor im planning on running this on with the 66mm alpha TB. My question is, can I run this on OBD2 ECU until I get my chipped ECU with hondata for tuning? I know it wont run optimally without tune, but if I do it correctly will it run?

[@GarageBuiltHondas]

Thanks for the support !! Yes, probably not optimally like you said but it should run just fine. I'm still running obd0 90-91 integra parts on my jdm b20b and when I did the swap with the IM & TB I didn't have an issue at all. Still runs super hard!

[@keenanwalker1313]

For sure thanks for the reply. Unfortunately I am running OBD2 stock ECU until I can afford OBD1 Hondata S300 set up, either way i think my engine is gasping for more air and really needs it if my stock ecu can keep up with the fuel trim. My concern was on the stock high rise giraffe B20 intake there are two vacuum hoses in the front, one is the PCV and the other goes down to the fuel rail. But on the Skunk2, there is only one for the PCV. Where could i re route this other vaccum?

[@GarageBuiltHondas]

You can just plug it off. They sell small packs of plugs at auto parts stores. It won't be needed.

[@keenanwalker1313]

ok cool thanks bro

[@GPMAX01]

If this was swapped in an EK and tuned on an OBD1 Ecu of our choice- would it still get by emissions with a jumper harness etc? No CELs? I live in a crazy state PA.! 🤨

so whats up with the pro version where do the gas lines connect ????

[@GarageBuiltHondas]

You'll need a regulator that's not dependable on the rail. AEM makes one as well as other companies. jhpusa.com/products/aem-universal-adjustable-fuel-pressure-regulator

[@isaiahalvarado4055]

Thanks for that feedback, now I know what'll need to be done if I'm experiencing any issues. Luckily this TB has been perfect. I haven't had one issue at at thankfully!

[@tylerlbrown565]

I tried installing the skunk 2 manifold on my b20 but the screw holes don't line up and the injectors don't reach. Do I need aftermarket fuel injectors/fuel rail.

[@GarageBuiltHondas]

You may need longer bolts or spacers to get it to fit correctly.

[@tylerlbrown565]

For the 2 throttle body ports that were bypassed, do I put vacuum caps on those? Can I also cap the port to the EVAP Canister since I don't have one? On the intake manifold, it has a large and small coolant port. I know the larger one gets used, but do I also cap the one right next to it?

[@GarageBuiltHondas]

Yes. Yes. You can cap off whatever you're not needing. For instance, some people remove the heater core and thus you'll cap off the lines which lead to it. So any that are not needed in your setup, you may cap off.

Hi Jon, Nice video! I'm looking into DPFI to B20 swap. Quick two questions: 1, on 7:40, two water lines on the intake manifold, the larger one goes to thermostat housing, the smaller one goes to which part of the thermostat housing? 2, Why I don't see the FITV on the stock intake? It's deleted?

[@GarageBuiltHondas]

One loops from thermo housing to intake manifold. The other goes to your heater core. Yes, the FITV is deleted on this intake manifold. I had the holes welded up and it was powder coated.

[@badassyuta]

@@GarageBuiltHondas Where does the small water nipple on the stock intake manifold go to? Did you Tee it to the thermostat housing, or you plugged it? Can i plug it if I want to delete FITV?

[@GarageBuiltHondas]

As long as the hoses go somewhere, then it really doesn't matter. To can delete the FITV if you wish, not recommended if you live someplace cold though.

[@gsub5886]

Is there a difference in performance with the new TB and intake manifold? I have B18A on my `92 Integra.

[@GarageBuiltHondas]

You may get like 5-10 HP without a tune. These parts definitely help if you do want to achieve more HP.

Hey I’m trying to find the easiest way to put the evap canister on to pass CA Smog smh.. it should be below the oem intake manifold

[@GarageBuiltHondas]

I don't understand what you're asking.

[@krizzi666]

What is the advantages over the original manifold and throttle body?

[@GarageBuiltHondas]

More air flow resulting in more HP.

[@txiong2546]

Similar set up but still using the integra throttle body and it idles rough 1k to 2k the whole time, any ideas? Could it be because of the fast idle thermal valve delete? Will deleting the iacv help? Thanks in advance!

[@GarageBuiltHondas]

You can see in this video where I run the coolant line which originally went to the FITV, but I run it straight to the nipple on the side of the head.

[@A1Santoss97]

Hey bro how did you remove the lower bolts from the manifold

[@GarageBuiltHondas]

Extensions and u-joints

[@bauerleinjohn]

What fuel rail is that I like the placement of the fuel pressure gauge

[@GarageBuiltHondas]

It's an AEM

[@usmanscamnewyorkcity8204]

Hey Honda Master, need your guidance on 3.5 Pilot That has a puddle of oil in manifold! Does this mean the piston rings are bad or just the bad pcv valve?

[@GarageBuiltHondas]

I'd check the valve first and replace it as they are inexpensive. If it persists, I'd run a leakdown test to see exactly where the issue is.

[@usmanscamnewyorkcity8204]

Garage Built Hondas thank you so much for the prompt response, pcv valve was clogged, so I will give it try with a new one and let you know too.

[@GarageBuiltHondas]

Skunk 2's websitte says tthatt intake manifold can handle up up to 75 mm, and the ttb you have linked is 70 mm, which conttradicts what you said in the video, your tb being 66mm. Is skunk2 correct or are you more accuratte? Wanted to make sure for my b20 build thanks

[@GarageBuiltHondas]

You may want to do some reading on what TB size is good for your power setup, then buy which you think is best for your build. I'm sure all the TB's that skunk2 says fit, fit.

[@majorleaguefoodgaming]

What kinda number differences (if any) have you seen post-installation?

[@GarageBuiltHondas]

Maybe like a 7-10 HP increase on this kind of setup.

[@spencersgarage]

Did you just put caps on the two coolant nipples on the throttle body?

[@nyfries]

where do you get that small L tip tool you use to unsnap clip and remove hose?

[@GarageBuiltHondas]

Any store that sells tools usually has them.

[@hondas8447]

When I install mine .mine excell ?

[@DapperDilla]

May be a bit of a noob question....but will the stock throttle body work with the Skunk2 manifold

[@GarageBuiltHondas]

Yes. 👍

[@zanenourse8679]

Is that an Obx type R racing strut? If it is we're twinning Jon! I have a matching one! Haha. Just got in my Hasport Cable to Hydro conversion setup. I was thinking about doing review video since I have it installed, would you be interested in me sending you some footage to perhaps use as a new diy video. If you know anyone with that has that obnoxious cable clutch issue like me, that conversion might be the answer! Haha.

[@GarageBuiltHondas]

Zane Nourse Yes it is! Its served its purpose so far, but going to swap one from my Si soon. Send me the footage, that be awesome!

I had a question about the charcoal canister in my 00 Integra gsr the charcoal canister has a vapor canister shut-off valve on top and I see that yours doesn't have it. My problem is that they swapped a b18b1 in it and now there is an open vacuum hose in the back of the intake manifold where you extended your vacuum hoses to reach but there's nowhere in the charcoal canister to connect it to one vacuum hose goes into the firewall and the other one goes into the throttle body. Any help would greatly be appreciated thank you!

[@sergggio15]

Also thank you for the video explained everything really good 🙏

[@GarageBuiltHondas]

Block it off then.

[@jacobmaloney7203]

The IAT behind the fuel rail. Is there supposed to be a gasket, with a small spritz of brake clean, behind that is my vacuum leak ive been hunting. Just not sure if that sensor should be silicon Grey or if there is a gasket

[@GarageBuiltHondas]

I believe the sensor had a small rubber gasket.

[@jacobmaloney7203]

@@GarageBuiltHondas i appreciate it. The shop cranked it on though so I have to find a way to loosen her

[@GarageBuiltHondas]

Impact screwdriver is your best bet. I just googled it. There is a rubber washer

[@teknoman0818]

Hey i wanted to ask what size bolts did you use for the intake manifold and where did you get them from or if u can send me a link thanks

[@GarageBuiltHondas]

I have tons of Honda hardware.. I just dug through my box that day.
