Thanks.

I've wanted to do a short intake for like... forever.
I just saw more and more people do it and thought, damnit, i need to do it.

Now lets say I do remove these emissions parts. What do I use to cap off/plug what they attached to?

The charcoal canister has a hose that comes from the fuel tank right? Which is fuel vapor, now if I cap that off completely won't that create an unwanted vacuum in the fuel tank?

 

fuel vapor hose you have to leave unplugged. you CAN plug it and have more of a pressure release when you open your gas cap during fill ups.

for the scv i dunno what to cap i didnt have that, nor the AIV, but with the AIV i think u can buy a plug for the stock header fitting to plug.

the egr is plugged via fittings or crimping the return pipe. or shove a nickel, yes a 5 cent nickel, and put the fitting over it. works perfectly.

usually just trace the vacuum lines that arent going to be used anymore and cut/cap them accordingly.

 

awesome, thanks for the tips.

going to hopefully do an electric fan install this weekend and remove some crap from the engine bay.

 

You can removed a lot of the vacuum lines. Removed the Entire EGR assembly and cap the intake manifold. Then once that is off take off the controller thingy, which is right next to the EGR. A lot of vacuum lines are connected to those two and it cleans up a lot.

I have also heard you can remove the two sensors on the very back of the engine right behind the valve cover.

 

anyone know if my motor will run like crap with all these vacuum lines removed/capped off?

I won't know if it throws a check engine light unless I check the ECU.
I have a california model car which has an exhaust gas temp sensor, and a non california motor which doesn't have it.
so I already have a check engine light.

Anyone have a non california model s13 5spd ECU?

 

Well I'm doing all the things you have metioned doing and more. As as far as I know my car is a non california car. I'll post pics and tell you how it runs if it runs.

 

there werent any california or non california model cars. we all have EGT sensors on the intake manifold...if you remove the EGR, you can cut that too. or just leave it there. you will get codes unless u put a resistor in for part of the EGR system, which i have yet to do since i forget where it goes

http://www.240sx.org/faq/index.html heres a great source. it has the butterfly removal on it and i think some other emissions removal as well.

 

hmmm
my FSM says that the codes I get are from California models for an exhaust gas sensor.

and I didn't get the code until I swapped the motor when I first got the car (I had 2 91's, one had bad oil leak and knocked like crazy, so I just swapped the two)
