Intake Manifold Options for the 1.6
 

So lately I've been searching around for alternatives to the OEM intake manifold for my 1.6. I had seen that FM/BEGI offered a replacement alternative for the 1.8, but nothing for the 1.6. Ebay offered a china-manifold that was a velocity stack very briefly, but that seemed to fade away. Is there any IM upgrade available for the 1.6? Has anyone retrofit a honda B series edelbrock manifold onto the 1.6?

There appears to be someone who did it to a 2002 head on plainmiata.com.

I take it back.. the China-Mani is back:

$700 wow!

Chinafold.

Translation: Won't fit worth a shit, prepare to modify.

People thats not from China. Its from Thailand. And it looks well-made too. If BEGi or FM were selling that instead, people would be tripping over themselves to buy.

But I do agree that $700 is a bit over the top.

I'm sure it fits fine...i'm sure you have to make it work for the TB of choice...I'm sure it's awesome...I'm sure it's overpriced ;)

Thai-a-fold just doesn't sound as funny.

quality looks great, no doubt, but for $700 id better get a mail order bride included, at least for a few months...

Hang on, where do the injectors go?

Sure is better looking then this:

Those runners in the Thaifold (point to be noted jayc72 :)) seem to be too short, and the plenum volume is higher. I wonder how that affects things. It looks like there will be a loss of torque at the low-end because of that.

It's a 1.8 manifold. Text says they are working on a 1.6.

aren't the injectors mounted in the head casting not the manifold?

maybe for the 1.8. In the 1.6 they sit on the manifold IIRC.

buy my IRTBs and get the Anniversary Racing manifold!

The manifold is like 1500 USD

Or make your own.. ;)

that thing is sex. more info on the car/mani?

Just find my build thread under my name, I think pictures are down... but I'm working now to upload and fix that with a different host.

splitime-did you build your mani volume specific, or just whatever it turns out to be?
Also, how did you decide on runner length? any math or just trial and error?
not bashing, im trying to get educated here...

Runners were based on a few out on the market. It was an attempt to find a happy medium based on midrange and topend. I didn't want it biased towards either. Angle for direct flow, all transitions were matched, surface left rough for fuel atomization.

The volume was designed to be large so it could provide a nice area for the velocity stackish base plate to draw its air from.

It was also designed to allow for simpler IC piping with the V-mount, otherwise the throttle body would have been almost into the blowoff valve location.
