I have a 1st gen B16 and was told by people at Mantaray Motorsports Racing that port and polishing my stock B16 intake manifold was just as good if not better than a OEM Type-R intake manifold. I just wanted to know if this was true or not. I wanted to get a Type-R manifold but not if i can just port and polish my stock one. Anybody know about this???

- bigger plenum
- plenum sits lower which enables the intake charge a more direct path to the intake ports
- shorter and fatter runners = top end power



Also, t/b size from the B16A and the R are different, B16A is 58mm and the R is 62mm...

 

i think the skunk 2 intake manifold is same as type r, not sure though. want to get one myself.

 

Get a hondata I/M gasket if you replace it... Just fyi...

skunk2 has a little different runner design

 

Thanks for the replies everybody i am differently going to purchase a Type-R I/M now. Now i just need to find one, anyone one have any ideas of where i could find one at a good price.

English?

Sorry, I don't understand what you mean. Ask me for advice? I gave him great advice and a picture. I must be confused.

 

Its a worthy upgrade, especially if you upgrade your camshafts to at least Type-R cams.

Once you install it, you'll notice your topend powerband becomse smoother and doesn't seem to struggle as much when you reach redline. You don't need to have a ported head to use an ITR IM. And I agree, using a Hondata gasket is a worthy item to have as well.

 

I saw a test on a second gen B16 swapping in a Type-R intake manifold. The results weren't that good, to what I was expecting. I'll post a dyno plot after I dig up the data. This was with everything fairly stock. Probably get better results with a more mods.

yup, like i said, upgrading to R cams + the R manifold will yeild some tasty power gains.

 

Get an AIR/Endyn intake manifold. They outflow an ITR mani by nearly 30%...

 

Flow numbers are only part of the equation. Just because a manifold flows well, doesn't mean its going to run on your engine right. The port velocity is MUCH more important. That is determined off of the bore and stroke of the engine and the camshaft profile. Since, without the proper velocity, the cylinder wont fill properly.

This is for heads as well as manifolds, a proper design will make the most horsepower, not which one flows the most.

I like how they advertise the flow numbers, but I couldn't find a before and after dyno chart!

Here's the dyno on a second gen B16, and swapping a TypeR manifold

I would deff. get a ITR or skunk2 manifold.
