Name this part and it's function:
 

http://pic14.picturetrail.com/VOL564...2/60418586.jpg

What is it called and what does it do? I went to change mine out for a different one and realized the noise I was hearing from it was the screw under the plastic cover that wasn't screwed in. After I screwed it in a valve on the inside moved and the rattling noise went away. I have no ------- clue what this thing is. Anybody know?

I think its just a little acumulator to soften out the fuel preshure spikes? If that makes any sence ???

Re:Name this part and it's function:
 

That's what I've heard, but I wasn't 100% sure. I wonder if that would cause me to run pig ---- rich? ???

Its a pulsation dampner, it absorbs the wave in the fuel that the injectors make when they open and close, if you take it off you run the risk of an injector running lean

Re:Name this part and it's function:
 

Thats what I was tring to say ::) I would make a terable teacher. I dont think it could make you run rich. Have you acually checked your fuel preshure boostie? Hows your o2 sensor? tell us more ;)

Re:Name this part and it's function:
 

I haven't checked the fuel pressure. No gauges. :( I can't even run the car right now(unless I plug the oil feed line)so I don't know if it's fixed or not. I changed the following:
CTS
O2
FPR
Fuel acumulator pulsation dampner ejaculator spaculator
Injectors
and a million other things that shouldn't matter, but I wanted/had to change anyways.

I guess I'll see if I fixed it in a few days. :-\

Re:Name this part and it's function:
 

I love that ---- ;) Let us know if it works or not. Time for some updated pics on your project to :D

Re:Name this part and it's function:
 

maybe ur missing a piston

sometimes they up and leave

Re:Name this part and it's function:
 

depends. i threw mine out on my rx7 and replaced it with a banjo bolt and it works fine.
basically the theory is to prevent pulsations form the injectors opening and closing. the result in this some people say is some parts of your fiel system exploding. i could see this happening if you run a solid line fuel system, but i have also come to notice that it doesnt happen to cars with non solid fuel lines. my rx7 doesnt have solid fuel lines and the rubber lines absorbe the pulsations.
when things explode its likely a cause of water hammer.

Re:Name this part and it's function:
 

also, i wouldnt advise driving it again untill you get a new one. if the screw falls out that could be a sign its bad. mine was completely fucked. my screw was out and the flapper got sealed shut and the bastard part popped spewing fuel on the exhaust manifold. so i chucked it and replaced it with a banjo bolt cus they dont do ---- and are far more cheaper. also, some aftermarket fuel pressure regulators have them ( pulsation dampeners ) built in.

many rx7's have died from this.

Re:Name this part and it's function:
 

So its like a water hammer? Hmm I haven't seen that on my cars.

Re:Name this part and it's function:
 

yes, you would ;)

Re:Name this part and it's function:
 

lol

Re:Name this part and it's function:
 

Kain? Is that you? ??? Thanks for the info. ???

Re:Name this part and it's function:
 

That truley is some sad spelling :o I know when its wrong I just dont know how to fix it or it will take me too much time to figger it out ::) Too much time in auto classes and not enough in english ;D

Re:Name this part and it's function:
 

Woah.. Kain is going all elaborate on us now.. :o

Re:Name this part and it's function:
 

na, its prolly one of the useful things he picked up from owning a rx7, i bet he can tell you how to make a fuel switch too ;)

Re:Name this part and it's function:
 

I might be pickin up a 1g RX-7 for a real cheap winter beater.. anything you would recommend checkin out? (And yes, I would be drifting in the snow as well) :-*

Re:Name this part and it's function:
 

nothing really, just a compression test... on a rotary a compression test will tell you everything

Re:Name this part and it's function:
 

yah, beat the snot out of it. those 1st gens are really good. put a p port in it and expect huge gains. somewhere between 250 to 300+ with other mods. but it would be a race engine if you p port it.

Re:Name this part and it's function:
 

yea, if you do the work yourself you can do a p-port for very cheap, then just harden the stationary gears and get some good bearings in there and you will see around 300 HP @ 13,000+ rpm

Re:Name this part and it's function:
 

depends. if it has low compression it might mean too many things. if its just a beater, then what i would suggest putting atleast some 2 stroke oil in the gas. also, when its good and hot, tap a vaccume line and let it drink some water. clean out everything. dont worry, rotaries dont really hydrolock. plus if its good and hot, the water will convert to a gas and therefor be able to be compressed, and will be basically steam cleaning everything. if its carbed, just clean the carb. if its fuel injected, get the injectors profesionally cleaned.

Re:Name this part and it's function:
 

Really.. because my neighbor said he goes to a tech school and would be able to take the motor and do all kinds of ---- to it.. hmm :P

::Sorry for jacking the thread:: :-X

Re:Name this part and it's function:
 

well a cheap ol pport isnt very good since it will also alter the timing ( not ignition ). plus, i would get mazda made p port housings and hurley ecc shaft. then it would rev to the skys limit. also you might wanna get a better exhaust, since that seams to choke them up pretty bad. also a turbo wont hurt.

Re:Name this part and it's function:
 

I might have access to an RX-7 turbo actually.. and a completely nother engine (12A I believe). I'll just beat the snot out of the catalytic converter and put on my old muffler, that should be good enough for me :D

Re:Name this part and it's function:
 

heh. dude, you could rebuild a rotary engine in 2 houres, and have it back in your car runing if you do it at a moderatly fast pace. should take 1 houre to get it out of the bay if its fuel injected. its just soo simple. a broken apex seal shouldnt be an all day job.

Re:Name this part and it's function:
 

heh, the rx7 will eat through it if its glasspacked.

cool man pick it up. these cars are little devils. ive seen a turbo 1st gen stomp a supra turbo.

Re:Name this part and it's function:
 

an hour? thats slow. ive pulled mine in 25 minutes with tranny... its so simple. And its going to be a beater car so i doubt he is going to have money for some brand new mazda p-port housings, this is HMT we are all interested in going fast for cheap. Anyone who can read could get the timing were they wanted thats why there is sites like vintagerotaries.com

Re:Name this part and it's function:
 

what about the water jacket?

Re:Name this part and it's function:
 

heh. well if its the first time, it might take a little more than a half an houre. but even if ya go slow it will take yah no more than 1 houre.

Re:Name this part and it's function:
 

ha you should have seen my friend... it took him 3 days to do a motor swap, i finally got mad and finished it for him

Re:Name this part and it's function:
 

heh. it took me 1 month to figure out my afm was busted.

o well.

i should have baught a starion.

Re:Name this part and it's function:
 

HAHA.. nice. I have access to a 13B for $50, think I should buy it and have him take it to his school and do sum ---- to it?

Re:Name this part and it's function:
 

yea

Re:Name this part and it's function:
 

Err wait, ----.. whats the engine in the first gens, the NA ones? :-[

Re:Name this part and it's function:
 

first gens use 12A's unless its a gsl-se then it has a 13B

Re:Name this part and it's function:
 

Its a 12A. Any good?

Re:Name this part and it's function:
 

12a's make for good p-ports, and they are cheap

Re:Name this part and it's function:
 

Not to mention, if one blew, I'd have a second ready to go ;)

Re:Name this part and it's function:
 

heh. you dont need a whole new engine. usually when somethign gives way, its like a seal or someshit.
