Id first pull those two hoses off that EGR valve, plug the one closest to the manifold and run the one from the T to the intake tube. Then work from there and see if that helps.

boris13

Ok and the egr came with it

boris13

K I got the waist gate connected to the bottom left nipple on the throttle body n imma take more pics so u can see how all my pipes are set up along with vacuums n all

boris13

K let me look into that guide thanks n yes I have the charcoal canister I'm about to take pictures of my engine bay

Nicelyphe

Disregard the guide, just took notice it was for N/A sr20's. The item your calling an EGR valve is actually an AIV valve, and yet again, is not needed.

di-devol

^If it's the AIV, then is this connected to your turbo elbow? If it is you need to get a plug for that.

boris13

a plug as in to cap it off??

Nicelyphe

Gonna have to block off any flow of exhaust from that hole. You could get an aftermarket elbow, they only have the 02 sensor hole in them.

This is most likely how your setup looks currently. Stock elbow and the AIV

And heres an example of a aftermarket elbow with the aiv port pre-deleted.

boris13

Ok yea heres the thing my steering wheel wont turn because of that pipe from the avi its rusted to shit so i dought ill be able to take it off

Nicelyphe

Yea =\, gonna have to most likely pick up an aftermarket elbow. It's your best bet and then you dont have to worry about any modification. Install and your good.

boris13

This is whats causing my steering wheel not to turn


charcol canister?


what is this plug on the turbo??


engine bay pics it looks horibble but i just want to get it running

boris13

the electrical tape is jus so i dont have a boost leak i dont think it worked tho..

Lil_D

the bov should be recirculated. if you are using the nipple on the lower left of the throttle body you arent getting enough vaccum for the waste gate. the nipple on the turbo is a vaccum line.

Nicelyphe

Going to have to remove this and plug somehow, or get an aftermarket elbow.




That looks like an AC line, I cannot tell if its going into your intake pipe for any reason, or going under it. Blue lines are where a hose should be, one from BOV to intake pipe, one from T to Intake pipe. Remove AIV. And whats that hose running across the top of your valve cover?



Also this hose is going to you IACV, doesn't look to secure. Most likely a vacuum leak. I would clamp that down [on both ends if not], it also doesnt look to be on the intake tube very well, I'd get a longer hose and replace that one. Wheres that vacuum line going that on the bottom left of the throttle body? I believe that one is plugged on mine.

What is that white mess right there in between the vacuum hose for the fuel pressure regulator? Right above the intake pipe I was just previously talking about. Looks like a bunch of teflon tape.


Electrical tape = no go on covering a boost leak from what I would think, if you think theres a leak there try tightening that clamp a bt more. I'm going to take some pictures of my bay sometime and then you can see a little better on some things. Yes that is a carbon canister, it could be deleted as well.

ok i just went to my 240 and i took that pipe that was restricting my steering wheel from turning and i cut it off with a grinder i plugged it up with this high temp silicone that my friend gave me he told me to use it on the gasket for the down pipe that connects to the turbo elbow but i used it to plug it up as well

he said to wait a full 24hrs before starting the car because it will get hot real quick and it will just melt off and will be no good

as for the hose running across the valve cover its my maf wires i didnt want them to get caught in the fan and mess up my wiring harness

the hose for the IACV i took off the old and rotted one and replaced it with a new good one and clamped it at both ends

the bottom left hose on the throttle body is connected to my waist gate idk if thats right i searched on here for a vacuum diagram and read that i can run it to my waist gate and it will be fine correct me if im wrong if so were does the waist gate vacuum go to??

the vacuum on the turbo where does that one go to??(the one thats plugged up)

as for the teflon tape its connected to my boost gauge i just wanted to make sure that i wasnt leaking any air through there so i get correct readings the way i had to plug it up was crazy the hose it came with just kept sliding out..

as for the hose that goes from the blow off valve to the intake pipe and that Ts of to the intake as well how would i go about doing that i have no nipples on my intake pipe:/

boris13

I aslo found this I have no idea what it is its cut and not connected to anything

Nicelyphe

Looks like a sender of some-sort, is that tapped into the turbo?? Also where did you get that intake pipe from? You able to source a stock intake pipe just for trial and error to figure out your issue in the mean time? It's dark over here at the moment but im going to attempt to grab some pictures haha.

Kingtal0n

"the vacuum on the turbo where does that one go to??(the one thats plugged up)"

The plugged line will never show a vacuum because it is tapped to the compressor. I would use it for the wastegate signal, that is, run it directly to the wastegate with No T's to anything else!

On the throttle body, there is a one vacuum port that does not show vacuum when the throttle body is closed. You can find it when you run the engine, it will not suck any air when the throttle body is closed. DO NOT connect this port to the fuel pressure regulator, or the blow-off valve. You CAN use it for a boost gauge, but it will not show vacuum during throttle closed position. It is designed for the emissions system.

Use a vacuum port that displays full-time vacuum, when the engine is running, it will be presenting a vacuum. Use ONE for the fuel pressure regulator AND bypass valve... and thats it! do not T it off to anything else or response will suffer.

High temp silicone will not stop that exhaust leak. You need to unscrew that rusty line, and stick a nickel under it, then re tighten. Buy an aftermarket elbow for the future but a coin will work for now.

boris13

Lol thanks I appriciate the help and yea it's tapped into the turbo I don't think it's the o2 sensor and the only intake piping I have is the one that's on the car right now and the stock Ka Sohc..

Not sure if it would work tho

boris13

The waist gate to the plugged turbo vac and I just cap the bottom left nipple in the throttle body?

And any advice to how to get it to turn loose with out stripping the bolt.?

Nicelyphe

Yea cap the bottom left, I have a picture of that.

Kingtalon is saying run your wastegate off the compressor of the turbo, where that plugged line is with that bolt, just remove the vacuum line from that nipple and put a vacuum line from the wastegate to that nipple. My wastegate is connected to a nipple that I have installed in my intercooler piping, but that's just another method to the madness.

Here's some pics for you too take a look at.


My source for wastegate [disregard that clamp, working on that in a few haha.


Throttle body
- Left nipple is going to my Fuel pressure reg. and tee's off to my boost gauge.
- Right nipple is BOV ONLY


In this picture you can see the bottom left nipple capped.


Hose coming off tee then leading down to intake pipe. I've seen people just put breather filters on this end of the T. But I have no experience with that..



Here's the BOV recirculating setup with stock sr intake pipe.




Hope this helps you out a bit.

boris13

dude thanks ALOT im going to do this set up tomorrow by any chance does ur BOV still blow off?? ive never seen a set up like urs i wish i could do it right now but im about to go to school :/ and could i just drill a hole in my intake pipe and run it from the BOV to it and buy a nipple or would i have to change it to a sr stock intake..

what kind of maf are you running on it the only thing that tripps me out is why does it throw out so much smoke when i drive it i know king talon you said its normal when first starting the motor but i mean it throws out white smoke excessively like in an over exaggerated amount ill take a video and show you how it runs would sea foaming it make a diffrence?

and it doesnt look like you have that same sensor thats on myne what turbo are you running?

Nicelyphe

Not a problem. Yea you cold nipple your pipe and run the BOV to it, just got to get a big enough fitting cause the BOV hole is like 19mm or something around there. My BOV blows off every time with any issues. You don't exactly have to change it to stock intake pipe if you dont want to, just modify yours.

My MAFS is the actual SR mafs. I heard the KA MAFS works just the same.

My turbo is the stock t25 that s13 blacktop sr's are equip with from factory. No I do not have that sensor looking thing, I don't really have an idea of what that could be. All I can think of is maybe someone wanted to read exhaust temp readings or something of that sort at one time. It looks like its tapped into the exhaust side of the turbo.

boris13

Yea Well I'll try tomorrow to see what I can come up with so at stock boost the gauge should read -20 at idle?

And well hopefully this fixes everything and if it keeps smoking up bad I'll just sea foam it and put new spark plugs and check for any improvement I mean my vacuums will be right so i dont think it should anything should go wrong unless its fuel related but then again i could still have a boost leak some where ill make a boost leak tester as well I'll post an update when I fail miserably again :/

Nicelyphe

Yea -20 at idle is good. Yea drive it for a bit and see if it clears up, hopefully nothing major. Also for your inter cooler couplers these things are a charm.

Tbolt Clamps 2.25 2.5 2.75 3.0 3.25 3.5 3.75 4.0 T BOLT | eBay

A lot better of a hold than regular hose clamps, and can be tightened down real nice with ease.


Keep us updated, it's a learning experience, for you, and others now that may run into the same issues in the future.

boris13

K dude once again thank you guys for all the help you don't know howuch it means to me I'm about to get home n run ur set up I'll update the progress so everyone can read this if their having any problems

As for those clamps I got them on every coupler and I re did all of them and tied them down till it couldn't go anymore hopefully it eliminates any boost leak through the piping ill post an update soon as I take her around the block again to see if it got better.

boris13

K i found a hole in the intake pipe can I run a vac hose from the bottom nipple of the blow off valve to the intake and have it recirculated.? Or does it have to be from the front big hole the hole I found is small enough for the vacuum hose..

Nicelyphe

Big hole, that's where the air releases from the BOV which in when it working order it recycles the air back into the intake and into the turbo. Its not completely neccessary to recirculate, just helps with response, and idle and such. Id plug that small hole you found though. Also maybe in the future fabricate something up so you can recirculate that BOV sometime.

boris13

K well I found it but it was already plugged up I guess so i can unplugg it and put something in it but I'll just leave it plugged up I don't have to put a vacuum to the bottom nipple right?

Nicelyphe

Correct, as far as I know a line doesnt go to that bottom nipple on greddy BOV's. Any progress with re routing the wastegate and the BOV and such? Try and get it started?
