can anyone tell me whaere this vac nipple goes or does it get capped.
Also on the front and back of the dinamic chmber there are three vac nipples. which ones get capped? I know that the ones in the front have something to do with omp.

if you mean the vac tube on the first pic.. mine were capped.. I used one for a vac guage

ok, How many vac lines should I have left with a bare block (no omp).
I'v been trying to figure out how to rout the vac lines but can't fine a routing diagram for a na.

The one in the first pic? That feeds into the nipple on the outside of the LIM that the pressure sensor hooks into, doesn't it?

Very nice clean engine man. attention to detail without goin overboard with silly colours.

redlineracer

Thanks staticguitar. I never liked those silly colors. My car is red and that's enough red for me I may even paint the ngine bay flat black so the engine will stand out.


Anyway can anyone help with the vac stuation?
Is there a vac digram someone can post up for na?
I want to install this motor soon since I've been working on this for about a year now.
Any information that can provide will be greatly appreciated.

Hate to bump old threads but I didn't want to create a new one. Is there a write up somewhere on how to go bare block? I've been searching the archives and this forum off and on with not much luck.

Hey I have everything hooked up and I turn the key it starts right up , the rpm goes to 2000rpm then it shuts down. then i noticed there is gas leaking through the injectors. What is the first steps i should take in this matter. I'm happy that it started up.
and it sounded pretty damn good

well you have a vacuum leak. Replace the rubbers on the injectors and make sure every possible vacuum source is accounted for and taken care of. One of the best investments for an rx7 owner is a vacuum guage.

You may also have either the thermosensor or MAF not plugged in completely.

ok thanks.

Ok I fixed the vac problem and fuel leak.
the car starts up fine the idle will rise to 3000rpm then drop. when it drops it bounces up and down. What can I do about this.

the bouncing up and down is still a vac leak. recheck every vac line and check to make sure everything is plugged in correctly.

i have three vac lines and all of then are hooked up. Ifound that the egr block off plat was loos so I put more of the red rtv stuff and tightened it. I also tightened the bac valve block off plat and the acv block off plate. i costom fabed a block off plate for the **** that was between the two secondary injecters, I think it went to the cold start assist crap.

Yup that's the cold starter thing (I forgot what it's even called). I had to fabricate a plate for that myself as well.
