I would be grateful of your opinion please folks.
A while back I fitted a K&N filter to my filter box inlet and removed the panel filter but it ran really poorly with lots of coughing and spluttering so I put it back to standard, I also had feedback about the filter sucking in hot engine bay air. Here are a couple of photos of what I did:

After that I put it back to standard and carried on researching and since have learned about mounting the filter behind the battery, resetting the ECU after fitting and using a MAF housing that is similar to the original for smooth air flow. So my next incarnation I thought of would be to get a standard airbox and cut the tube section with the MAF housing and use standard silicone hose and mount the K&N behind the battery.
What do you think, is this a sensible mod or am I wasting my time and it will just be noisier and with a lumpy power delivery? I'm not necessarily after a power gain (but don't want a loss) just a little extra induction noise.
Thanks for your input everyone, any comments gratefully received :-) :-) :-)
Sounds like it could work, Wabbit just done a nice conversion might be worth asking him where he got the bits from he used between the throttle body and filter.
Thanks FGrob, I had a look at Wabbit's kit, looks really good. Where did you get the bits Wabbit? I was thinking of using JJC R&R as they've been quite good in the past?

The Hurricane kit is from w www.elise-shop.com (http://www.elise-shop.com) w , then I added a 70mm-70mm silicone 45 degree pipe off eBay and cut it down in length to fit. Then approx 12" of 80mm ducting from eBay to the side intake.
I bought some 70-90mm stainless jubilee clips to hold it all together. It's not cheap but it works very well.
The filter and housing are a snug but nice fit with plenty of room between it and the battery. K&N do some generic filters and housings that are pretty similar and I reckon it could be used along with a maf housing to make a pretty effective intake.
I struggle to think anything would be an improvement on induction (due to ram-air) but if it's the noise you're after anything should work really, just give the car time to cut the ignition back a bit to account for the warmer intake temp and maybe ajust fuel trims a tad for lesser airflow. the side-scoops have very high velocity air passing by, you wont beat this for intake location imo.
Stock also takes from behind the battery, but it is not pointing into a position where it is ram air. Also to make the most out of the side vents in terms of air being forced into the engine bay then you need side scoops.
You miss the point, I never expected a ram air effect, to achieve that you need the high pressure at the front of the car.
My data recording shows power increase due to the larger intake capacity and big reductions in intake temperature. Intake temperature is ambient air temperature and therefore 20 degrees less than Apexi power intake temps. And 10 degrees less than standard intake minimum. Colder air is denser and therefore better for engine power.
I obviously have other mods involved but the result is very telling!
I will be refitting the e-manage ultimate for mapping eventually to make the best of it.
Most like me would fit an Induction kit for the sound - what does the Hurricane kit sound like in use then...?

It's not about noise it's about intake temperatures, the only place you get this benefit from is in front of the battery as all the heat generation is behind it. I've been throught the whole exercise and for sure you do have a big benefit on a hot day, Nic will also agree as he's stated above.
Quote from: "steeleyscoot"Most like me would fit an Induction kit for the sound - what does the Hurricane kit sound like in use then...?
Erm yes, it is pretty loud, at high rpm I can actually hear the intake valves operating through the intake... It's a bit mad Tbh.
My post was a general post, not aimed at anyone particular, sorry if it seemed that way.
I have not got the stock setup in mine, so assumed it was enclosed onto the side scoop.. Assumption, the mother of all.....
it appears it is not. therefore there is your best "upgrade" option for N/A imo, you'd get ram effect up front, but you'll also get it along the sides, high velocity air, high density air, all the air being forced around the car will get compressed and flow around the outer edges of the car at a fast velocity, at 50mph the airs probably more like 70mph.
get the oem box airtight up against the inlet, and maybe add a tiny "catch" lip to the inlet and bam.. pressurised intake system (dont go installing a boost guage lol) s:) :) s:)

I used a Bmc intake and re routed the standard intake through the rear quarter straight to the side vent. With my obd app I'm getting around 15 degree intake temps at 50mph with about 10degree ambient temp. Sounds nice and can hear it sucking in the world even with the roof up. Very long route though so I'm considering behind the battery but having a funnel feed from the side vent. Each to their own though.
Ps I do have a pic in my "garage" if that made no sense.

Here you go
(http://i493.photobucket.com/albums/rr299/wabbitkilla/The%20Car/DSC_0025_zpsgrunfcjw.jpg)
That's a nice setup. Have you relocated your battery or is it just out for the pic? Do you know what kind of intake temps you are getting?
Battery was just out of the way during fitting.
A picture paints a 1000 words!!! I now understand why a 45 degree bend had to be used and where to cut!
Just to clarify, the 45 degree hose: it's 70mm at both ends? Is this internal or external diameter? Damn my engineering intrigue!!!
Regards,
Jim
70mm internal diameter.
These are the additional bits;
Silicone hose (http://www.ebay.co.uk/itm/171091796677?var=470275938682&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)
Induction hose (http://www.ebay.co.uk/itm/310306097204?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)
Jubilee clips (http://www.ebay.co.uk/itm/161070319192?var=460192151608&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)
The maf mount isn't perfect for fitting the maf into it but it does seal with a bit of care.
You sir, are awesome! Why couldn't today be payday!?
Well, finally got all of the bits together and made this:
(http://i1085.photobucket.com/albums/j435/purplepowermonster/MR2/20140403_171411.jpg) (http://s1085.photobucket.com/user/purplepowermonster/media/MR2/20140403_171411.jpg.html)
It comprises of:
1. Standard airbox cut down to hold the MAF
2. 45 degree 70mm silicone hose
3. K&N filter (second hand ebay)
4. 70-90mm jubilee clips
I think the whole lot came to about £40. It took about an hour to cut down the airbox and another hour to fit it all in the car.
Fits really neatly behind the battery

Blimey, it certainly roars when you open the taps.
Thanks for all of you help everyone, I really appreciate it s:bounce: :bounce: s:bounce:
Looks great and that cold feed should be much better. Your just spurred me on to do mine as I already have the parts s:) :) s:)

Nice one, good luck with it.
Well worth the effort but I think your fuel consumption will go up as wide throttle openings are addictive.... Ha ha.....
Haha. I doubt my fuel consumption could go up anymore. I already have a BMW CDa, de cat down pipe and box less exhaust. It's pretty lary as it is :s lol
Is there a universal maf sensor housing available or is it worth just getting a spare air box and reducing it down to just the sensor housing?
Mwr sell an alloy one for about $35. Check it out I have one and it's a decent fit
MWR flange has to be welded on tube. The tube diameter is very important so the maf could read correct airflow.
I made exactly the same thing s:D :D s:D

I used araldite to attach it but I reckon any good sealant would do (free to corrections) just made sure I used plenty to give it a nice air tight seal. I'm pretty sure the maf sits in the right position but again can't be 100%
This setup will be changed soon to give a direct feed from the side vent s:) :) s:)
How does it work purple? Well? I, Like you, tried the first method.. failed miserably, run proper lumpy constantly!

Hi Tom,
I must say it works perfectly, no flat spots or hesitation. Like I wrote at the start of the thread, my last attempt was really rough running but I now put that down to not resetting the ECU after fitting it.
Go for it, you won't be disappointed s:bounce: :bounce: s:bounce:
Will go for it s:) :) s:)
How much did it put up the insurance by the way?
Hi purple. Does the MAF sensor wire reach the new position without any modification?
Quote from: "mwyse005"Hi purple. Does the MAF sensor wire reach the new position without any modification?
Sure does :-) :-) :-)
which K&N filter is it? universal as long as its got a 70mm internal hose fitting?? does it need to be a decent size? is bigger better so to speak lol

Hi there,
It's a K&N RC3250, here's a post of my first (unsuccessful) attempt:
l viewtopic.php?f=7&t=47039 (http://www.mr2roc.org/phpBB3/viewtopic.php?f=7&t=47039) l .
I agree with your comment, you can use a universal filter, not sure it needs to be too big, but there is plenty of room behind the battery anyway.
Why thank u kind sir s:) :) s:) another to add to my list of things to do, loving my 2 tho, got drilled and groove discs, pads, induction kit, alloys,tyres, steering u/j, full service, gonna be a busy few weekends for me! Then bodykit, then wrapping it s:) :) s:)
Wow, that'll be awesome when it's done. I got mine as a bit of a 'wheeler dealer' car so had to do quite a few jobs to get it up together. New wing, headlight, wiper motor, wiper switch, tyres, wheel refinishing, then I could get onto the fun stuff like UD sub (well recommended), new HU, Alpine amp in cubby, lowering springs, induction kit, TRD exhaust and now I just love driving it. Passed the MOT last week without even a comment s:bounce: :bounce: s:bounce:
What sort of money did you pay for the disks and pads?
Got them from mtec, the disc where 140something, drilled and groove, and coated black s:) :) s:) got on there site and it explains the coating, had them before in my corsa and my god it could stop lol and my corsa was 151bhp 1.8sri, 0-60 in 7seconds s:D :D s:D was abit of a beasty, nobody expected it, just looked like a corsa C shape lol
Well as it's raining and I can't drive the 2 I've ended up on eBay buying all the bits to do this for the bargain price of £26.48 delivered!
Just one question, is the k&n filter cleaner a must as it's obviously second hand for that price or would carb cleaner do the job or do I not need clean it at all before fitting?
Thanks
I would say carb cleaner would be fine but i have no experience to rely on.....
Carb cleaner works well, did a good job on mine!
Fab, carb cleaner it is then.. Thanks

Purple, sorry but a bit of an amateur, but thinking of doing your behind the battery job. did all you do was getting get the 4 things above fit them together then put onto the car? Or did you do something with the ecu?
Great write up!
Already bought the maf housing from elise parts so time to get the K&N and silicone pipe on order!
Hi there, sorry for the delay, fitting is as easy as you describe then reset the ECU by leaving the battery disconnected for a bit an then reconnect it and go for a spin (and enjoy the noise [WHITE SMILING FACE])
Brilliant :-) :-) :-) cheers
I ended up going with the bmc version, ordered it this mornin. Got a maf adapter from spectre performance of eBay.
Just need to play the waiting game now
Quote from: "purplepowermonster"Hi there, sorry for the delay, fitting is as easy as you describe then reset the ECU by leaving the battery disconnected for a bit an then reconnect it and go for a spin (and enjoy the noise [WHITE SMILING FACE])
Any particular reason why the ecu needs resetting?
Gaz
Not really, but I did a mod by removing the air cleaner from the air box and fitting the K&N on the inlet and it ran terribly so I put it all back together as standard. Then I read somewhere that I should have reset the ECU so I did when I did the behind the battery version I reset the ECU and it ran sweet. Better to be safe than sorry was my thinking....
How's it going?
I ended up getting a k&n apollo, some silicone hoses (got wrong sizes at first!) and will be using Patrick's 3D printed MAF adaptor. (For 2zz swap)

Have you fitted it yet? I'm held up waiting on my MAF adapter s:evil: :evil: s:evil:
No I don't even have the engine in the car yet s:D :D s:D
Hahaha fair enough reason
Sorry to revive an old thread but I thought it'd save repeating the subject really.... s:roll: :roll: s:roll:
I'm looking to do this but can't seem to find the right k and n filter on ebay as they only list outer diameter in inches s:? :? s:? Has does anyone know which one will fit?
Also found a universal apexi filter..... comes with metal flange outside diameter 76mm ..... I'm guessing I'd need a rubber reducer or would it fit onto the cut airbox?
m http://www.ebay.co.uk/itm/221714059178 (http://www.ebay.co.uk/itm/221714059178) m
70mm internal diameter is what fits on the stock maf. So 45deg pipe needs to be 70mm internal as well. 2.75inches
The one I used:

Fairplay that looks nice.....
What's the quality of the filter like? And sound wise? As loud as the others?
I now have this very kit fitted to my car (bought from shnazzle) and it's great. Well recommended.
Cheers guys. ....... bought all the bits so gonna be knocking this up next week hopefully s:bounce: :bounce: s:bounce:

See my pic. That's it cut to the right size
