after some changes, i added a 62mm throttlebody , with some handwork on the intakemanifold...

now the car is a little faster on 0-60mph (7.1-7.3) and increased top speed

speed..

good mod who somebody is interested

this mod added to the other in my forst post....

IM STILL WAITING for and increased rpm range!!!!!!!!!!! ANYBODY HAS ANY INFO...???????????????????
MTH TUNING SOFTWARE STILL ON 7200!!! they dont think in the increase, but i think is a big mistake...

You modded what?

The plastic air intake??

I'm thinking on fitting the cooper S air intake and "work" it.

Need some mods and a bypass to work.. but i think i can do it..

i also have an enlarged throttle body.
Its a cooper s but a little bit enlarged(about 60mm)

After a lot of thought, i decided that none of the aftermarket intakes worth the asking money, so i made my own one.

I removed the stock resonator (that was a pain in the ass...), and i used a flexible pipe which ends exactly behind the hood grill, and has much smoother angles than the stock 90 degree bends. Some pics :

....... soooo what does that do? any sound differences?

Before i do this, my intake was totally stock except for the K&N panel filter.

Then i removed the resonator and left the factory airbox with just a hole, in other words, exactly what you see in the pics but without the flexible pipe to bring cold air. This setup was cutting power, and i felt that it wasn't reving good, after 5000rpm it was noticeable. The only positive was the sound, so loud that i couldn't even hear my cat back and very agressive. I feel that the Intake Air Temperature was VERY high with this setup...

Then i added the pipe, which brings cold air in the box. The loss i had is restored, and the car feels good now. I can't tell any difference in sound compared to the stock airbox, but i am pretty sure the IAT is a bit lower even than the stock intake, and the flow is increased with this mod. (resonator removed, pipe sitting exactly behind the grill).

I am under the impression that intakes like DDM and Afe, although they make very nice sound, they hurt performance compared to stock. There are members who have noticed this using these intakes, and it sounds normal to me, since the IAT is going high, and the flow ON TO THE FILTER is decreased. To make it more simple, what is better, to let the engine suck the air totally on it's own, or create airflow to help?

Just my opinion

I care more on handling than power, that's why my coop got some stealth mods on it. rear sway bar,drop in filter,h&r springs, control arms(rear) and upper stress bar. that's all for now.

REVO EVOM · #**108** 08-05-2009, 09:48 PM

I have a stock 02. What are some good upgrades to add power?

wildcrazy442000 · #**109** 08-06-2009, 11:12 AM

A DDM cold air box, a performance catback (Borla or something similar). The other options start getting very expensive. I just traded my R50 in on a R56. After three years of modding my R50, and getting little extra performance, I felt trading was the best option. That and my R50 spent 4 months in the shop .

MiniMe02 · #**110** 09-15-2009, 03:42 AM

Yeah, I am wondering the same thing. I too have an 02 Cooper and want to add some extra HP and MPG to it without breaking bank. What are some viable options and about how much would this cost. Is this a D.I.Y. project?
Thanks

nickbmw · #**111** 09-15-2009, 06:10 AM

A cold air intake, and a cat back system, will not make you go faster, but they'll make you think you go faster, because of the sound. If you want to really go faster, and not a placebo effect, get a Fidanza flywheel, a camshaft, a header, and then get a tune. These are going to make your car really faster. If you can't afford all of these, keep the flywheel and the header with a free flow cat or a de cat pipe. This way you will not need the tune as well.

MiniMe02 · #**112** 09-16-2009, 03:18 PM

I was looking at headers...they're like $1,500. That's more than I want to spend, for the time anyway. First thing I am going to do is to get the WAY/DDM Cooper CAI. Reviews say you get a little more MPG and according to the product description, a slight power increase. Even if that's not true the sexy sound would be well worth it to me

Where should I shop for these parts so I can check prices? I'm sure camshafts are expensive and what do you mean by a "tune"? ECU upgrade? And what is a free flow cat? Sorry, I'm new to all this stuff. Thanks for helping.

nickbmw · #**113** 09-16-2009, 03:31 PM

There is no header going for 1500... You can get a decent header at 175 plus shipping, like OBX. You can use your oem cat with it, or spend 100$ more, and get a Magnaflow free flow cat. The free flow cat shows less resistance to the gasses going through it, because it has larger holes.

Fidanza flywheel, not very expensive part, but costly labour to have it on.

The camshaft is about 400$, but this is the last you should look for of all the above.

The ECU tune, is a remap done on a dyno, where the software of your car is been optimized according with the parts you have. There are vendors here who can do it, and i think it costs around 350$.

MiniMe02 · #**114** 09-16-2009, 03:45 PM

Hey thanks. I just found a magnaflow for $472 at http://www.autoanything.com/exhausts...0A3038783.aspx

What are the reputable sites you would recommend I shop at? (low prices +high quality). And would you suggest the WAY CAI or the free flow K&N air system?

There is a stage 1 upgrade here: http://new.minimania.com/web/Item/NMK1001/InvDetail.cfm would that be worth the price or would you suggest something else altogether?

I want to get a noticeable difference in power and fuel economy for as little as possible. Even better if they are D.I.Y. projects to save on labor.

nickbmw · #**115** 09-17-2009, 07:04 AM

Τhis is the free flow metalic catalytic converter to suit an OBX header. I have used this shop a few times, and i am very pleased. An exhaust shop is needed either if you choose to fit the OEM cat, where you will have to cut it from the stock manifold and weld it on the OBX flange, or you'll have to weld the Magnaflow on the OBX. You could also just make a de cat pipe...

This is the Magnaflow cat back, if you insist :

If you ask ME, i would suggest the same CAI with mine, you will find it a few pages back in this thread. But the DDM CAI is a nice piece, just a not true cold air intake. A friend of me has it on his R50, it makes nice sound but not sure about the gain compared to my much cheaper solution.

If you follow my advice, you'll have a faster Cooper, because i've been through this already... But better milage, i don't think so. Especially with the CAI and catback, you'll floor it all the time just to hear it :D

There are no easy DIYs that will make your Cooper faster... Making N/A power is a really hard task...

MiniMe02 · #**116** 10-16-2009, 02:16 PM

OBX looks like a good one to go with however, I'm leaning towards the Megan Racing Exhaust/headers. The exhaust is $380 and the headers are $179. I don't have to pass emissions testing so would I even need to worry about welding on the catalyst?

I might just get the ALTA panel filter.
Because the K&N panel filter is inside the air box, is there still the possibility of the oil from the filter messing with the mass air flow sensor?

nickbmw · #**117** 10-17-2009, 09:34 AM

I was also thinking about the Megan header, but after my search here, i found a lot of people had problems with them, so i avoided it.

There isn't any problem with the oil of the K&N, unless you reoil it too much after cleaning. Even if you do, still you won't have problem, your car deosn't have an mass air flow sensor, but a map sensor.
