I am sadly putting my 96 gsr back to almost stock after it being JRSC. I sold alot of the stock stuff a few years back. I don't need to smog test so I am not really concerned about a CEL, I just want it to run right. Here are my ?'s
1) Is that little vaccum tank under the manifold really neccessary for the secondaries? I currently have one of the small vaccum lines coming off the back of the manifold into the vaccum switching valve for the secondarys, then off the switching valve I went strait into the secondary valve. I did leave the little check valve installed.
2) Is it ok to run it without that big oem intake bracket, or will I run into cracking issues?
3) I am running a stock ecu, and still want to run my endyne breather kit (currently venting to atmosphere). I read a thread on here that said without a pcv valve I will run lean. Wont the fuel trims compensate some?

Thanks for any input.

 

are you willing to sell the setup..?

 

1) The IAB technically could work without the tank. There could be situations where the IAB would not close properly without stored vacuum.

 

By set up I assume you mean the JRSC, sorry everything is gone already. I do still have the map relocator kit and a walbro 255 for sale.

 

When you say "close" do you mean when they open up under accel, or are you refering to them "closing" (shutting off) on decel. My thinking was (and I may be totaly wrong), since they don't open until 5500ish rpm, that should provide plenty of vaccum to operate it. And when rpms drop and the switch turns off the vaccum it should close, right?

 

The normal position for the IAB is open butterflies (high RPM). When you start the car, vacuum is applied and the butterflies close (low RPM).

When you drop below about 5750 RPM, vacuum is applied to close the butterflies again.

 

Thanks for the help.

 

i'm trying to turn my car stock so i can pass smog.
