z31 Emission Delete and Front end conversion

[teck]

If anyone is interested in step by step emissions delete please feel free to ask me and don't listen to the crap of its on there for a reason. My car runs so much better without my emission junk.

B/c FYI to you people that say that when exhaust gas is dumping back in your intake tube it carbons up your throttle body

and I have a simpler way to put a 1987-89 front end on 1984-1986 than Xeonz31

[AZ-ZBum]

I'm curious what the simpler way to install the front end onto an earlier model is. How much simpler?

Also, while it's not very likely to happen, if a cop does check under your hood for some reason, and all that emissions stuff isn't there, you are suspect to federal laws, not just state and local. It's not likely, but it could happen.

Basiclly all the cutting and welding That guy did on Xeoznz31 is not nesscary i was ably to beat out the metal where the head light sits and bolt up the middle bumper support with out one single cut Ill have to go thru all my pics and post them

and yea I know the legality concerns but my car runs so much better without the recirclutaion of exhaust into the TB

[DoctorRobert]

Well, I'm certainly interested in the emission delete for my '85, if it will improve it...

Truth. I'm not sure why the guy doing the conversion decided you must cut out the front of the bucket. I wouldn't even call it beating the metal out, a little tapping to move it outward slightly so the lights don't rub.

If everything is working proper, it won't make a difference either way in warmer climates. In colder climates you might not be so lucky.

I run zero emissions/idle control equipment and my car starts first crank from dead cold and has as low as 30-ish. Took it apart before it got real cold just recently.

The only effect the cold can have on my car is no coolant circ for my TB, so its "possible" for it to freeze up on me if the car were to not be able to warm up and said moisture created a vacuum seal.

stripped and gutted plenums FTW.

Indeed.

[Vegaz31]

I realize this thread is old but i'm interested in the deletions. I want to get rid of everything in my bay, Um

[evildky]

engine bay with deletions

[Vegaz31]

Did you do all this with the stock ecu?

[evildky]

mine, no I megasquirted it, no more iacv, no more ficv, no more maf,no more a/c, no more power steering

[Vegaz31]

well guess ill save for a megasquirt. ive heard alot of good about em

[evildky]

Megasquirt isn't for everyone, and if the car is a daily driver I think i'd opt for a rumulator instread. But for unlimited functions on a track rat you cant beat megasquirt.

I would really be interested in how to remove emissions if this forum is still active. If anybody can help me out that would be great!

[evildky]

Define "remove emissions"? If you're just asking about deleting the egr people have been doing this as long as there has been egr's. The easiest thing to do it simply disable the erg valve, by plugging the vac line that actuates it. I removed it to make service easier. If everything is working properly you shouldn't notice any difference in how the car runs without the egr.

Getting rid of the smog stuff is a good thing if you can get away with it, an 80's car is not as big as a 70's car, my 77' Celica with all smog deleted was way faster, could go 120mph top end instead of 105mph, but in CA I still pass a bi-annual smog check and will have to do so for the rest of my lfe, just not worth it.

[FrankTheKoyFish]

How did you do the emission delete?

[ROCKS9900]

If there’s any way you would like to get ahold of me I can give you my contact info but I have an 86 non turbo and am trying to take out the emissions bs but don’t know where to start

[BadQ45t]

sorry dropped the thread, on my old 77' i took out smog pump and cat converter that was all i those days before CA had bi-annual inspections. Plenty of people in CA pay off a shop to not get a smog test, but the smog test station people can literally go to jail now. To show you how old I am I also made a leaded gas pump fit in and ran leaded gas for 5 years, may that lead was good for the engine!

The above engine looks sweet, but removing power steering, no way, my Celica didn't have power steering but it weighted a hell of a lot less than the Z and I still would have liked it when parking.
