Still learning my way around the new FD (new to me anyway). While trying to find a boost leak (I think I did) I noticed these 2 items which I'm curious about. 2 red arrows are pointing to them in the picture. One looks like it's supposed to have a vacuum line attached to it, and the other is a line with what looks like some type of little filter on the end of it, venting to the atmosphere.

Anyone know what these are for? It looks like the previous owner purposely put the little vent thing on that one line, so maybe it's supposed to be like that. But at the very least it seems like that other nipple should be connected to something or at least capped off no?

 

Those are supposed to just vent.
I suggest that you check the couplers and clamps closey.
You have had the lines swapped to silicone so you most likely are leaking at a coupler.

 

Sweet thanks for the quick reply. Just wanted to double-check before I put it all back together again.

 

dave's right, but they also are different on an automatic car

 

Really?
What are they hooked up to on an auto?

 

Where is the vacuum chamber?

 

just go single so you dont have to deal with the rats nest anymore

 

Below and the slightly on drivers side of the alternator.

 

they have a check valve and an extra solenoid i think

also automatic cars have water temp sensors on the thermostat housings

i'm sure there's other diferences, those are the ones that caught me off guard

oh yeah, and automatics are slow

 

I'm SERIOUSLY thinking about it. Only had the car a few short months and just now getting around to having the time to play with it. Need to do a lot of research before deciding what I want to do, what turbo, etc.

 

Geez... a properly running sequential should be experienced before running and hiding in the non-seq grass! Seriously, FOLLOW the diagram, either the one in your manual (and why don't you have a copy, they're essentially free at iluvmyRX7.com) or the colored version online (search this forum).

if you are still having trouble. Sequential is very nice, and not really all THAT hard..

Sorry 'bout that. Just get a little peeved at jumping to the non-seq and wasting all that engineering effort that is bunches of fun when it works right... I'll slink off into my corner again...

 

I noticed in your picture, in the stock y-pipe, i see a little oil in it. I was just wandering if someone can tell me if that's normal, cause i get that much oil too. You can see it pretty good in the picture.

 

Just a bit of advice (that many of us have learned from)

The moment (don't go for a beer first) you expose your turbo intake or the moment you take the UIM off the car get some racers tape, some rags (not as good) or some masking tape and cover that hole. Anything can fall in there and you are looking at a very bad day if that happens.

I used a latex surgical glove over the front turbo intake and just a couple of pieces of tape to cover the LIM.

Do it, live by it.
