How to install a skunk2 k series intake manifold on a Honda prelude(H2K) - Parts list

[@arbazraza1981]

It’s hard to find good videos towards preludes and installation part videos. Keep up with the good work sir. I just bought a 94 prelude si and your videos really helping me learn a lot about my car thanks

[@automotiveobsession7265]

Thanks. I had the same problem when I bought the Prelude so I just decided to make videos about common and specific information about the prelude. I appreciate your support.

Yes pleaaaase

Keep unloading my Guy whenever the time is right hope to see you at the San meet on the 22nd champ god bless you and Yours

Thanks man I really appreciate it. God bless you and your family as well.

Man, I love this guy. If he’s ever in Seattle, hit me for a free cut lol

[@automotiveobsession7265]

Thanks. Appreciate the positive comments.

Thanks for mentioning which throttle body to get with k manifold. I wasn’t sure what to get for my H22.

[@automotiveobsession7265]

Thanks. Glad it was helpful. All the links to all the parts are in the description of the video.

So what is the benefit of this manifold over the stock one?

[@automotiveobsession7265]

The idea behind using this intake is that because of its shorter and wider intake runners compared to the H series intake manifold it would supply the engine with more air and at a slightly faster rate. I found out after ordering and trying to fit these parts that because the engine is not leaning forward like an H swap in a civic and because of the downward slope of the ultra race manifold that it makes contact with the rear T mount. This could theoretically be fixed by somehow modifying that mount or creating another adapter for the manifold that would put it at a different angle but could cause other problems with the set up. I’ve read many times that the best bang for buck solution is to modify the stock manifold or get a euro R manifold. I’ve only seen one prelude run this manifold and it’s the WRD racing prelude but remember that’s a race car and there’s some parts that could be modified for race use only that could hurt everyday driving capabilities.

Don't forget to sleeve the block like I did!

[@automotiveobsession7265]

Thanks for the tip but I don't plan on doing such an in depth build. Just trying to see how much power it will make with bolt ons. Nice prelude SH.

[@redrojo22911]

What's the benefits of a 70mm throttle body vs the 68mm, 74mm? Or does it not matter? And can you do a direct bolt on with no tune?

[@automotiveobsession7265]

One of the benefits of a 70 mm throttle over the 68 mm one is that the 70 mm will just allow more air into the intake and engine because of that 2 mm difference in size. Now from what I have learned the bigger the throttle body the more it will affect driveability and this is a street build so I think 70 mm is a sweet spot where I can increase the throttle body size without sacrificing driveability. From what I've also learned you do need a tune because of the change in injectors.

[@elijahbacchus5510]

Did u have figment issues putting it on a prelude ???

[@automotiveobsession7265]

Yes. It doesn't clear the rear transmission mount so therefore this exact setup does not work.

[@Youngflynsaved7]

What cc are those injectors and do you have to run a specific ecu for those injector adaptors?? I have the p28 ecu

[@automotiveobsession7265]

Stock RDX injectors are 410CC.

[@Youngflynsaved7]

@@automotiveobsession7265 I have a question and thank you to the video because it helps so much . But do I need to have a different idle control valve and does the sensor come for the intake manifold for the K series ??

[@Youngflynsaved7]

What tps sensors and map sensor are you running ??? Same for h or k ?

[@automotiveobsession7265]

With the H series throttle body you can still use the stock H series TPS and MAP sensors. This is the reason I chose the H series throttle body so I wouldn't have to rewire any sensors.

For those with H22A Preludes, what is the benefit of doing this? Flexibility in intercooler piping or something?

@@automotiveobsession7265 Thanks for the reply and detailed explanation!

[@jefunftmarket9132]

Can this work with a h23a?

[@automotiveobsession7265]

This did not work with the H22 because of the T mount in the back of the engine. Because the K series manifold is turned down it makes contact with this mount. If you can modify this mount to allow clearance for the manifold to fit then this should work. Also if the H22 stock manifold bolts up to the H23 head then it should be the same bolt pattern for the Skunk2 adapter to fit and then the K series manifold bolts up to that.

[@Handicaptain02]

cool set up but whats really the point of running all the adapters when you could just get a upgraded h22 intake?

[@automotiveobsession7265]

I could upgrade the H22 intake manifold but I just wanted challenge myself by trying adapt this manifold to the H22 engine. I also wanted to provide this content for anyone that is looking to do the same to their car. I have seen this done to the H22 but in race cars for the track only. I have not seen an example running this setup for the street.

[@activvortex1483]

Hm for everything in total?

[@automotiveobsession7265]

I have to calculate it so I can give you an exact amount. I will make a video explaining how to install it on the car and there I will add up all the prices of each part. Stay tuned. Thanks.

[@muthafukkajones]

Where is the install video bro??

[@automotiveobsession7265]

I have a video for Saturday that will explain everything. Thanks for the interest.

@Automotive Obsession awesome! Nobody has this setup and I'm going to buy it

@@muthafukkajones That's exactly what motivated me to do it but just wait until this Saturday afternoon so you can understand some things I learned when trying to install everything.
