intake manifolds

[91hondaturbo]

So i am building an f22b1 out of a 97 accord, that i am swapping into my 91 ,but i am having a hard time finding aftermarket intake manifold. I will be running lots of boost ,and i wanted something bigger then stock because i also wanted to gain hp off it too

u posted in the wrong thread buddy

Moved.

Your money will be better spent elsewhere in a turbo application. You could have the throttle body bored and enlarge the opening on the intake manifold or a lot of F22B1 guys get the intake manifold from an F23A. It's a much better design and bolts right up. With a turbo, though, you don't have a need for the same things as NA guys.

I'm guessing by the nature of Jarrett's post that H23A1 manifolds are not compatible. However if they were, I would recommend the Golden Eagle one.

[Jarrett]

You can make them fit but it involves a ton of work. The ports line up but those on the head are physically smaller. I've seen threads about it online and I've also seen it at the junkyard.

i had a friend also tell me about the h23 manifold joey and jarrett i know i dont need it but im looking for an aftermarket one because i may do an 8 injector setup but they are hard to find in general, so im just looking for aftermarket at the moment. If i can find one with eight injectors sweet if not oh well but i would like an aftermarket one

Obx manifold that's been cleaned up would make good gains. You have to remote locate your iacv though.

While you're messing with the topend build wise i would suggest an F23 head it out flows the F22b1/2 heads. The F22b's have crap intake ports.

I hope you're not building the F22B1 because it has VTEC, if so you're not going to get the gains you would want. I'd go pick up a head from the junkyard from an F22Ax and use that. The F22B1 is a replacement fuel economy engine for people on a budget when their engine craps out. The F22Ax head will out flow the F22B1 head all day not to mention the ports are more compatible with other Honda engines, like the H23 intake manifold directly bolting up to the F22Ax head. The H23 has a larger plenum than the F22A6 intake manifold, and the difference in runners are subjective (short or long) to what you want.

Just remember the power your engine puts out is dependent on the flow rate of the head. Your head as a whole (cams, springs, etc.) is what really dictates the amount of power you can produce.

It's your car and your build, I just wanted to shed a little light for you.

Honestly, even a stock head will flow more than enough for a street-driven turbo car... any of the F series heads will work for that. You'll reach streetable traction limits long before the head becomes an insurmountable restriction. Yes, the F22A head is much better, and the F22B1 VTEC system is a waste when it comes to performance... but a fully built F22B1 will make plenty of power. Too much power in a FWD car is pointless anyway, as there comes a point where you won't be able to keep that power on the ground.

I've heard mention of people using the F23A1 intake manifold as an upgrade on the F22B1. You might want to check over at CD5tuner.com for info, as the B1 is their engine, not ours. If you need to register, use the "contact us" link and provide your screen name. Registrations are done manually at the moment.

No I'm not building it cause it has vtec I could have drilled holes in my a1 head if I wanted it I'm just building it cause it was spare and I can put it in whatever I just am looking for an intake manifold that's aftermarket and bigger then stock I want it built top to bottom if everyone is saying the h23 bolts up then that's what ill look at and who cares which flows better I could any head I'd like on the top its my motor not my child its replaceable if it breaks bad enough ill put something else up top maybe an f20b head I don't know I just have questions I would like answers to thank you everyone for your input

[Jarrett]

Everyone is not saying that the H23A1 manifold will fit. I'm saying that with tons of work it can be made to fit. It's not the best choice. Putting an F22B1 gasket on top of an F20A/F22A/H23A1 gasket will illustrate why.

The easy choice for an F22B1 is the F23A1. It's a much better internal design and the port design where it bolts to the head is the same.

I'm sorry the f and h and next to eachother in my phone I meant f23

[deevergote]

Ok, I'm locking this. The best information has been given already, and the OP reads as well as he types. No need to continue the discussion further.
Good luck.
