What aftermarket intake manifolds are available that you have seen work? I am sure that I will hear a bunch negative comments on the OBX units, but I am looking for something else that will work without the $500 price tag of the GE unit.

Thanks,

Blaze

 

You're not talking about the OEM upgrade right? You wanna know what companies makes them for the F22Ax?

 

I would prefer to stick with OEM units but the problem is even the OEM ones are too tall for the hood to close on my EG with the F22 that is in it.

Your eg has an F22 in it? WTF

 

no different than someone putting in a H22. I almost did it myself but my plans changed. Someone showing the F series some love

Blaze45,
Speaking of the H22, my brother-in-law had an H22 in his 92-95 hatch and I don't recall him ever talking about clearance issues between the hood and IM. Are the two setups that different? Does your valve cover clear the hood without issue? I only ask because I don't recall the IM sitting above the valve cover by much if at all. Is it possible the motor may be tilted forward making the IM sit higher than it should? Maybe using a different rear mount bracket on the motor would allow the back of the motor to swing down just a bit to allow the IM to clear the hood?

 

H22 IM fits F22?

 

Yes.

The H22a IM does not fit the F22a. The H23a stuff is interchangeable.

The engine doesn't really seem tilted, but compared to how it sits in an accord it is titled forward. I don't know if it clears the valve cover yet because the IM won't let it close. The IM just sits so tall...



Also the H22 IM isn't as tall as the F22a one is. H23 IM isn't much different in terms of height.

 

How much is it sticking out? Couldnt you just do the hood prop thing that was a fad awhile ago if you don't need much clearance?

 

Two questions


1. Why would you want an F22?
2. What did you do about all the vacuum lines?

 

What's wrong with the F22? People have shown that you can get good power out of them. In both naturally aspirated and forced induction setups.

OP, have you looked into using an F22A6 intake and removing the IAB plate (secondary throttles) there was another member looking to do this same thing. They opted to have the upper and lower intake matting surfaces machined to lower the total height. that is an option as well.

 

GA, I believe you are referring to the same user...

hmm... have you thought about using a different rear mount bracket on the motor? Like maybe one from a H22? Maybe that would allow the motor to sit back and lower the intake manifold to a point it would clear. What rear mount bracket and mounts are you using? I assume you are using a H22 into EG mount kit correct?

Also, like GA mentioned, are you able to gain enough clearance by removing the IAB plate from the IM?

 

Is the h22 manifold shorter?

Is there enough clearance for this?

i have seen a dyno of a OBX manifold on cb7tuner, but the guy said it was modified and never told what he modified. i think i am going to see what one will do

 

what mounts do you have? I had an h22a with both HCP and Hasport mounts and was able to fit the stock manifold, euro-r (which sits lower) and the skunk2 under the hood (it had firewall clearance issues).

 

The washers/hood trick... I can't find bolts that are long enough for how much space I need. And bought some REALLY long bolts! haha


1.The factory F22a head flows more air then any B series or H series. Less then $100 for a long block from a bone yard. $100 for a D series tranny... Im cheap!
2. Capped em.



Yes this was me... If I was going to have the IM milled down, I thought why not look and see what other IM's are available cause I figure unless its the GE manifold it is going to cost about the same.

There isn't an IAB plate on my F22a1 manifold.

I don't have any firewall clearance issues with mine...

Also, Andryzzle that link you posted up... That could potentially be an option!

Thanks for all the input so far!

 

300hp 215 trq from a NA F22? Impressive!

 

That's not your everyday F22. IIRC that is Steve's (2point6 formerly of collective racing) girl friends car. It's sleeved and bored out, with oversized valves and running 11.*/12:1 compression.

Wasn't sure if it was you or not. I can never remember all the members and the threads that get posted. You probably should have kept the same thread going. Instead of starting a new one on the same subject.......

 

ah, gotcha, for some reason I was thinking you were using an F22A6 IM.
