wtf is this??

i was looking at some pics of honda's when i came across a few engines with this little thing on it... no idea what it is.. can anyone tell me?

Edit: hrrmmm stupid freewebs is acting up again

Edit#2: ok... that little blue thing... i had it outlined before but my host site seems to be down or something.

Umm that would be a red X sir.

HAha just kidding pic does not work.

there we go...

That is a breather filter, it is aftermarket, there is a hose running from there to the intake pipe stock. Some people change it to a filter. I have mine like that and have for some time now. It is not anything that will really help you any though unless you go boost, but then I would just do a catch can instead.

breather filter eh? never heard of it... what is it's purpose for boosted engines?

to tell u the truth, that thing is more of an engine ornament. it's not like ur going to gain any horsepower off of it. i admit, i had one on my crx and it looked cool but that was probably its only purpose.

if anyone is thinking of getting this eventhough they already got a cai, i wouldn't reccomend it. just use the stockhose and connect it to the cai so u get cold air, instead of the hot air from the engine bay. of course, if they want it for engine dress ups, then by all means, get it.

It is just part of the Positive crankcase ventalation system (PCV). You change it when you go boosted b/c you don't want to force boost onto the crankcase lol.

hmm, that makes sense.. lol

ok a couple other questions that are completely off this topic... i just didn't want to start another thread.

will i need to get a new MAP sensor or use check valves if i'm running boost but have the aem ems?

also, is getting the crank blueprinted worth it? if so how much would it cost me?

i love flaming my own threads :p

Ha, what a dip. You don't need to blueprint a crank unless you are doing a full engine rebuild. Even then it may not be nessicary....
A new map sensor it not needed, just a little devices that goes between the intake and sensor.
By saying "running boost" do you mean Turbo? if so, than yes, then it is recommended to check and do a Valve Lash. (that means adjust, for the dumber people.

hmm, that makes sense.. lol

You can get check valves to fool the map sensor from reading boost. recomended only up to 7psi

if you are are using aem ems.. then you'll prob need a 2-3 bar map sensor.

oh and the breather is for the oil vapors to dissapate.

oh goodie.. bar 3 map sensor!!! more freaking money x.x

lol well if you can buy a 1200 fuel management system then.. a 3 bar map sensor shouldn't be a prob.

1650 actually.. and that doesn't include shipping (i'm up in canada) but it's not that i can afford it.. it's that i will afford it... i'm going all out... but that doesn't mean i like dropping the cash :p

Try looking into Hondata I think for a street driven car (not strickly race only) hondata is better than the AEM ems. Yea the AEM unit does a few more things than the hondata but the hondata does everything you need it to do and then some. You can run the hondata and a GM 3 bar map sensor along with some bigger fuel injectors, a bigger fuel pump, and a FPR and there you have a very nice fuel management setup, far better than any of the FMU units that comes with turbo kits. :2cents:

even with my boosting goals? i though there was something special i had to get with the hondata to boost over 7 psi?

Like I said the Hondata and GM 3 bar map sensor. Ofcourse you will still need the normal higher flowing fuel pump, new injectors etc but all that stuff is needed with the AEM unit as well.

hmm, well i see where you're coming from... but with my swap i'll need to get a new ecu anyway... and rather than buying one then piggybacking it with the hondata, i might as well get the aem... most people would say to go rip an ecu out of a wrecked gsr.. but i don't think there is a single one in this town.. maybe 4 or 5 gsr's total. so much for getting parts off wrecked cars:(

ok so wait i was thinkin the same thing for my set up (the AEM unit) but i am gonna be runnin over 7psi daily in my CRX and well i have the fuel pump the injectors and everything else but would the hondata be worth it? i mean will it be able to perform as well as i want it to? or would i be better off with the AEM unit?

yeah, i will be running around 14 or 15 psi daily.. depends what the tuner says is ok. for the block to handle.. that's why i was going with the aem.. was going to get a tuner from the states to come up for the day, do some tuning then take it to the dyno to finish up the tuning.
as for your question 91crx.. i'd say you'd be plenty happy with the hondata, all you'd need to do is get the boost option on it and you're good to go.. maybe a new map sensor, the only real reason i'm going for the aem is that it's directly plug and play... no messing with wires, or ripping open the ecu and soldering a chip in there (you can pay to have that done.. i'm just trying to stay as cheap as possible) -figures that i'm going with the more expensive standalone eh?- but yeah.. you should be fine with the hondata s200 system with boost option

are you sure? because i know this guy who put a turbo in is prelude and went with the hondata and it did not work for him so he had to rip it out and put in the AEM...i just want to make sure im not gonna have to buy 2 things when i RELALy only needed to buy 1 thats all that i am gettin at...and im not sure if there is any hondata certified guys around where i live....thats the other...but maybe ill hafta check it out

Any tuner that is worth going to for tuning a honda should be very familar with hondata.

Overboost.com I believe wrote a nice article on the PCV valve. Pretty informative but I was sort of confused at the end as to what I was supposed to do. They mentioned the problems with just using a tube and running it back into the intake, and problems with just using a breather. They also said something about replacing the PCV Valve but again, it seemed kind of inconclusive.
