What is a good air intake to run when not using a MAF?
My turbo is evo 3 16g and I have read that the FP intake with the reducer coupler is bad idea.
I looked at this as an option http://www.cxracing.com/mm5/merchant.mvc?Screen=PROD&Store_Code=CXR&Product_Code=PIP300-AI&Category_Code=PIPE
I want to get all the fittings for welding to the intake pipe for the evap purge valve under my battery tray, the valve cover breather (soon to be swapped to a calan catch can). Also I want to get a K&N air filter. I like the look of this one STM: K&N REPLACEMENT FILTER KIT | 95-99 DSM

Some help on decision making would be appreciated.
Thanks

That oval filter is not going to work with that pipe. You need one like this: STM: K&N CONE AIR FILTERS | RU-4260 | RU-3550 | RE-0930 | RU-2590 | RU-5045 | RU-5111 | RE-0920 the The 3" ones at the bottom.

Or this: STM 3" INTAKE PIPE KIT (NO MAF) | 95-99 DSM

Build your own for super cheap!

2.25" piping:
Aluminum Pipe

Coupler:
Silicone Bend

Then all you need is 3 t-clamps, and add your choice of air filter.

Both the pipe and coupler have 45* bends. I can't really type how it looks, but I'll attach a picture (excuse the crude drawing).

Basically just go:
Filter>aluminum I/C pipe>coupler>turbo inlet

Enjoy!

Beautiful ^^^

But, like stated above, you don't need to buy any specific brand intake. Making one yourself is definately in the cards once you drop the maf. Just make sure you are protected from water and its drawing cool air.

Or just slap the filter on the turbo itself.... haha

The reducer coupler on the fp intake is 4 to 2.25" to fit a 16g
,

If the 3 inch pipe is used, you will need a reducer. If you want the pipe to match compressor outlet, then you'll need the 2.25 pipe like Logan suggested above, with matching coupler I found this pipe too http://www.cxracing.com/mm5/merchant.mvc?Screen=PROD&Store_Code=CXR&Product_Code=PIP225-

It all depends on how u want to do it. Do you plan on running the intake to the front bumper area (cold air)? K&N RC5000 filter attaches directly to an oval pipe like Dejon. I ran that setup for a while. My current setup is (From Turbo to bumper)2.5-3" coupler, 3" inch S shape intake pipe (cut in half), 3"-4" 30* coupler, 4" inline spectre filter(6" body), short 90* white (painted black) pvc pipe from Lowes, 4" flexible pipe, to 3.5" roof pipe flashing from Lowes. Ram air setup! works GREAT!

I have a dejon pipe with vc & cc fittings if interested.

I wasn't going to post this here, but what the hell why not. I used to make my own 3" aluminum intakes for $40 shipped(including filter and couplers). Here's how.

1) Get a cold air intake for an 88-91 Honda CRX. It has to look like this New Cold Air Intake Oiled Honda Civic 91 90 89 88 CRX 1991 1990 1989 1988 | eBay

2) Cut it in the area that I've shown in the box. You can make it shorter or longer depending on 1G or 2G and how much room you have/want.


3) Throw the clamp and coupler on, and go. I can confirm that the coupler with this intake kit fits over the 16G compressor cover with no issues, and isn't too big at all. The filter is great as well, and can be cleaned with the K&N recharge kit.

4) as a bonus, you'll have an extra 90* section of pipe. Buy another 3" coupler, two cheap worm-clamps, and it'll relocate the filter in the fender well, high enough up off the ground that puddles/rain isn't an issue, but at the perfect spot for fresh air, away from the hot engine bay.

5) Enjoy.




As a bonus, this is how it looks on a 1G with an extra coupler. Perfect location for a filter.

Wow lots of choices! Any benefits from putting filter into old smic whole?

Cooler air, which decreases the chance of knock, plus cool air compresses better. It's not going to be a HUGE benefit over just leaving the filter in the bay, but it isn't going to hurt anything either.

The ram air does help once car is up to speed.

What did you use for that? I've been thinking about a special design for an intake and that looks like a good material

Pipe roof flashing. One of those things that go around the pipes that come out the roof. You can get them at Lowes and Home Depot. Comes with two tabs with holes on the end, perfect for a bolt to go thru.

If you do he the old SMIC spot be careful of when it rains, the filter will get soaked.

Not with my setup. My filter is under the hood inside a canister.

There is a gap at the top and bottom where the flashing meets the bumper scoop. This allows some water to drain. The 4" flexible pipe is perforated also. I still think some water could come up but it would be more of a mist, which then still has to make it past the filter to get to the turbo. I have driven in a storm and car ran fine.

I ran the 4" FP w/reducer on my 14b (old car) with zero issue and am about to do it again on my e316g (new car) because it worked so well. I don't see how it is a bad idea, from my experience it works extremely well.

There is a dyno test lurking around somewhere where an FP intake was tested against an Injen (or knock off.. can't remember) intake. The 4" FP dynoed lower for the 2.25" inlet than the Injen intake. I love the FP intake myself but apparently it hurts performance on smaller inlets.

Hmm, how much lower? I'm not switching intakes because I love mine as well but it would be nice to know whether or not there is truly a significant decrease in performance.

EDIT: I found it

Compared to what?

It definitely works, FP doesn't make anything that doesn't. It has however been shown by one member to prove inefficient to reduce the intake diameter from 4" to 2.25" so close to the turbo inlet. This doesn't mean it can't be used. I've personally run the FP 4" intake with the reducer on an evo3 16g and made awesome power on 25psi, SD, and e85.

IMO, this reducer coupler exists so we can run the nice, cast 4" FP intake while on a t25, and simply swap in a 4" coupler when we upgrade to a 4" inlet 3586 or the like.

Thank you sir! I'm not sure ill use bolts and I'm sure it's gonna need a little fabing up but my plans are similar to what you're running

This is the photo at the end that's broken. Sorry for the bump but someone messaged me pointing out that it's a broken link. Here's the picture.

I have the same turbo for my 2g and I plan on just running a k&n filter clamped directly to the compressor housing. I don't like the look of a intake pipe, just personal preference.
