AIV Help

[WestSlide240]

hey i removed my aiv tubing because its stuck on the steering arm. now when i start my car it runs hella rough and stalls...smells like gas and etc.. How do i fix this?? i already searched and found nothing pretty much.....thanks

[compactfean]

Whatever is removed must be capped off. (I recommend doing a boost leak test with ALL fresh swaps anyways) and see if there is anything leaking in the pipe.

You can find an AIV hole plug online (try the sponsors like Enjuku and FRSport) for cheap.

Or the old dirty trick: cut the pipe off close as possible to the threaded nut, shove a nickel in the hole, screw nut on and JB weld the crap out of it.

[WestSlide240]

I did the nickel trick, its plugged. but its idling like crap still, i unplugged the maf and it idled fine so i thought it would be a bad maf and i took the maf off of my SOHC and wired it in according to the frsport guide and it is still idling like s***. so i looked at the wiring and everything is right but i noticed something else.....im running the stock smic and on the top of it where the pipes go into it, theres a vacuum inlet there.....what vacuum line is supposed to be there??? Also on the bottom of the smic kinda by the tire theres a big inlet or outlet thats wide open with no hose on it, whats suppossed to be there???

[compactfean]

The oem bov goes on the side of the smic. If there is another vacuum nipple somewhere on there than it should go to the wastegate (or boost controller)

[WestSlide240]

The wastegate solenoid, the one that is on the same bracket as the ignitor chip is disconnected because it connected to the fuse box that was on the old s13 clip i bought. And i was told to not use the other fuse boxes, to use the ones that were in my car. but the big a** inlet or utlet, whichever it is, the one that on the bottom of the smic, whats supposed to go there? Its like the diameter of the inlet on the radiator.....

[compactfean]

Bov

[WestSlide240]

Yea that didnt come with the clip.....what should I do?

[compactfean]

Well you will need a blow off valve. Preferably recirculated like stock. You can get a stock one from a dsm or srt4 or something or go aftermarket. either way you will need one. As far as that boost solenoid just get rid of it, its not needed and if you're going to be running a boost controller will be eliminated anyways. As far as thr fuse boxes leave everything stock. Only engine harness needs to be altered to work.

[WestSlide240]

Yea i got all the wiring done. Heres a link to what im thinking about getting, will this work for a fmic and bov setup? will it make my motor not run so rich and run like crap???? http://www.ebay.com/itm/CXRacing-INTERC ... 64&vxp=mtr

[compactfean]

Yes that will work, no it won't fix a running issue unless your issue is from huge boost leaks. (is that hole open?)

[WestSlide240]

yes i put a cap in it and test drove it, it bucked like a mofo! and it blew the cap off... the company i got the clip from must have removed the recirculation valve and they plugged the vacuum line on the bottom side with a pencil. the metal inlet for a vac line on top of the smic is wide open and so is the big inlet in the bottom....what will happen if i try running it with both of those plugged up??

[compactfean]

Blow a turbo

Please take a step back and get ALL your vacuum lines and intercooler piping 100% correct and leak free BEFORE YOU TEST BOOST!!!!!!

If you overboost because the wastegate is not working right, you will detonate and break ring lands and then you will be looking for a new engine block or new pistons, and cylinder boring.

This can and has happened in the first 10 minutes of driving a new swap. Unfortunately I have seen it several times in person.

All this info on vacuum lines and IC piping and BOV's is on FRsport.com and in the sticky FAQ's at the top of NICO and in the OEM FSM. You need to sit down and do some READING. Don't you want to KNOW exactly why and what has to be done rather than just relying on others to tell you how your engine works?

It complicated and tricky, but it has been discussed, diagrammed and stickied to death.

[WestSlide240]

I looked and cant find anything on the topic. How do i get to the FAQ's on Nico?

[WestSlide240]

Here's the problem though, I couldnt use the EAI valve or the Boost Pressure Solenoid because my fuse boxes in my SOHC werent wired for the plugs that go to those two. So they are unplugged. Also my steering arm was getting hungup on the metal tube that comes from the downpipe to the EAI control vlave, so i unhooked everything and took it off. And most important the clip didnt come with the recirculation valve that goes on the intercooler. But I'm lost still. I have looked and got no good answers.....Can I remove the charcoal canister as well? I cant find a recirculation valve and i was planning on just buying this..... http://www.ebay.com/itm/CXRacing-INTERC ... 64&vxp=mtr Will this work? so I have a good bov so i dont over boost....I heard ppl saying the since it blows into the atmosphere the car will run too rich because it is not recirculating and the air flow meter is getting a false reading, but at the same time ive heard ppl saying that the bov has no effect on the air flow meter, and the motor will run fine... Please I need help

[compactfean]

If your running your bov open atmosphere on a stock ecu it will indeed run rich in between shifts. You can run any bov (greddy, hks, blitz) as recirculated. You just have to run the exit to your cai AFTER the maf. The jdm egr has to go and the air injection usually isn't kept either due to the difference In exhaust. Charcoal canister isn't needed. There isn't a ”cookie cutter” way of doing a swap but you need to know the basics. What are you confused about?

[WestSlide240]

Im confused about what you mean by running the exit to my cai after the maf? And how do i recirculate the bov thats on that cx racing fmic setup i showed you?

[compactfean]

Recirculated= running tube from the bov exit to the cold air intake after the maf. Same thing with the bov from that ebay kit.

[WestSlide240]

I know what recirculated means lol! I just dont get how im supposed recirculate an atmosperic bov since it blows into the open air, and it has the discharge funnel...like am i supposed to hook a hose up to the discharge funnel and put it where?? Sorry for my massive confusion but I'm new to the sr20det scene....

[compactfean]

This isn't sr20det specific but yes, for example if you had a hks ssqv bov you would need to buy the recurc fitting and run the hose from the fitting (that would be installed in the bov) to the intake. Another example would be the greddy bov but it doesn't need a fitting, you can just run a hose straight from the bov to thr intake. Bov's aren't open atmosphere or recurc specific, it just depends on how you plumb it.

[WestSlide240]

So the funnel where the airs blows out, you get a fitting and put it in the bov, and then a hose and put the hose on the intake?? Like thats what im confused about, like on the hotpipe where the bov flange is welded to the ic pipe, where you mount the bov, you run the hose from the discharge funnel to where? like do i have to drill a hole in the hotpipe and put the hose in it or what?? lol sorry im probably way overthinking this!!

[compactfean]

No, the intake. You know the thing the maf is connected to before turbo not post turbo.

[WestSlide240]

Yea the tube that the cai is on then maf then the turbo housing...so I drill hole in it and put a hose in it?

[compactfean]

Yes, check this home made setup out. Just make sure its air tight though.

[WestSlide240]

Hmmm I see alright, Thanks man!

[blkvrtswp]

1) Block the open pipe from the stock side mount intercooler recirculator outlet.
2) Install any BOV that fits on your hot pipe flange.
3) IF you recirculate the BOV (nice but not critical usually) the outlet from the BOV needs to be piped to the inlet port on the rubber intake tube that goes between the MAFS and the turbo compressor inlet.
4) If you do not recirculate the BOV, block the recirculator inlet on the rubber MAFS to turbo tube.
5) If you do not have the rubber MAFS to turbo inlet tube, you can buy one or make one. If you make one, it will need the recirculation inlet ONLY if you are recirculating.

EDIT: thanks to whomever this pic belongs to...


The recirc inlet is the larger port at the opposite end of the filter, with the worm gear hose clamp showing.

[WestSlide240]

Thanks dude! I appreciate the help and info you guys could give me! Im new to the turbo scene. Im used to working on my Chevy and Jeep, but I am learning Nissan pretty good.
