Write up on Rats Nest Removal that's 13BTII Specific?
I have searched like crazy, and all I could find was "This is for a S5 non turbo, but others should be similar" I want a 13BTII specific writeup on removing the rats nest. Thanks guys

me too. i am going to end up doing a 13b-rew swap and need to know what changed over 7 years.

You need to keep only:
Air bleeds for the oil & fuel injectors. Fuel pressure regulator can be a short direct hose from the manifold. The pressure line that T's to the CPV & the pressure sensor. The oil pan vent (on the filler neck) to the canister or a catch can. The boost control line from the compressor to the waste gate (with the stock boost controller or your own). I used the bottom front nipple on the TB for my mechanical boost gauge. http://208.62.166.66:82/guest/Shop_M...c simplify.jpg |

Now...to make life more difficult...what are the differences for the rats nest removal between the J-Spec and the A-Spec?
|
looks like you need 4 nipples? is that right?
the oilcatch is that optional? just connect straight through if not going to use? |
That diagram is pretty self explanatory. I used the angled nipple on the inside of the LIM for the FPR. Everything else I pretty much did the same as the diagram above.
I've been running no oil catch can and I'm doing fine. |
Question: On that big picture up there ^ it shows a nipple on top of the UIM that goes to the Pressure sensor and the air bypass valve. Mine doenst have a nipple on top of the UIM, but I do have one directly under the BAC...will that woprk or am I using that for something else?
|
I am also looking to do this to my 88t2 and was wondering if i would be taking off the BAC and ACV along with the rats nest? when do block off plates come into play?

k now I'm REALLY confused
look at this diagram off 1300cc.net: http://www.1300cc.com/UIM/plans.jpg the main difference is where the Catch Can goes & what to do with the associated plumbing so which one is RIGHT??? |
I havent run a catch can for 3k miles now and no problems.
|
bump for more answers
|
another question, the vac nipples that are directly next to the secondary injectors (the angled nipples).......do i cap those or do i run a line to somewhere?
|
aren't these to help atomize the fuel or something?
|
You want to keep the air lines for all 4 injectors.
If you are running the MOP, then you need those air lines also. |
i premix....so what's up with these nipples? cap 'em orrun them somewhere?
|

Im talking about the angled nipples on the bottom of the LIM that are right underneath the secondary injectors. I heard somewhere that the vacuum helps atomize the fuel better... |
Take a picture. I'm thinking you are talking about the subzero cold start assist (not sure if that's the right name) that mazda said to rip out of the car as a service bulletin since you said nipples. Is it kinda gold/bronze colored and have 2 nipples in a U shape? I've only seen one before so dont remember it too well.
