here it is!!


MY TRD/OBX.TSUDO STYLE header Write-Up/Install

Well guys I started the install of my header late yesterday, just before I got off work. I couldn't wait. I had to special order new Exh. Mani studs & lock nut from Toyota, that arrived just moments before I was going to leave. As you all know I have no exhaust pipe. So I'll begin at the header installation.

Part #'s we all know or should know the QTY. is 5





Step 1:

I cannot speak for all, but I feel this will be mandatory. You will need to check all weld-on bungs, and or merges/collectors!! I reccomend you clean and De-burr areas pictured. ( EGR port/ o2 sensor bung.)

EGR


o2


Inspection of collectors




Once everything is within your liking, proceed to step 2 of install. If you've bought new studs also proceed to 1a.

Step 1a: No pix.

If you do not have, I reccomend you buy or borrow a cheap tap & die set.
- Thread or Chase each Exhaust manifold w/ the 10 x1.25 tap.
- Clean tapped hole w/ brake or parts cleaner.
- Apply small amount of anti-seize to new Exh. manifold stud ends ( that threads into the head )
- Install stud w/ a GOOD hand-snug ( if you have girlie grip, prepare for a long day! hehe j/k try your best ).

Step 2:

Next you will be installing the Exhaust Manifold Gasket ( supplied w/ header ) Here I removed the dizzy, my preference only.
- I took the liberty to clean w/ a toothbrush sized wire brush around the Gasket/Header mounting locations.
- If you choose to remove the dizzy, mark dizzy location, and be very gentle, trying not to turn gear upon removal. you will upset ignition timing, either way a small adjustment will be needed upon re-install.
- Just slide the new gasket on



- In this pic below you may have noticed stud(s) removed. I've heard stories of people. installing their aftermarket headers and having install troubles were the flanges have issues w/ headstuds in. So I tested this header w/ each location problem.
A: Center Hole/Bolt - Removed then re-installed, to test location B
B: Outer Left Bolt Beneath Dizzy - Removed then re-installed, to test location C
C: Outer Right Bolt, closest to firewall - Removed then re-installed - header Installed w/ all 5 bolts in head.

Note:
- With all headstuds in the header did require a slight rock side-to-side motion. No damage to studs occured.
- Header fit snug ( like Airmax 92's)
- Some flanges may have a different clearences, and ea. car is different. if you experience any difficulty upon install try to remove the stud in the problem area, or dremel the clearence needed at the flange. <- not endorsed or reccomend. Last resort if all else has failed.




Step 3:

This is a picture showing you the proper install postion to clear the rack column
- Turn you header until the flange points upwards towards you
- Slowly lower your header paying attention so you don't bind anywhere and force header in, damaging any other components.

- Header install - clean snug fit held itself in place.
- Turn your rack 'N' pinion, check for binding/contact
- No clearence issues here...........Hurray for the manufacturer!!! ( I was worried about this area specifically )



Step 4:

Install the headstud lock nuts to fasten extractor securely to head. This is a 2-step process ( MOST people. OVERTIGHTEN HERE, DO NOT!! )- Beginning for the center bolt in clockwise pattern install lock nuts ( 5 - 3 - 1 - 2 - 4 ) to 9 ft. lbs ( 108in. lbs.)
- Then repeat tightening pattern, this time bump the Torque up to 18 ft. lbs ( 216in. lbs )

Step 4a:

Re-install any other components you may have removed and adjust to spec.

Step 4b:

Showoff your install pics & clearence. ( excuse the jnky look =( )






Step 5:

Crack open that drink and relax to the smooth sounds of an open header....LOL put your exhaust back on.



so work was slow the day before yesterday and while sitting around waiting for jobs, the mod bug bit me.

So with ideas & dreams flashing through my mind I strolled to my hachi, reversed it into my stall & got to work.

I first removed the rear fascia......getting ready to install????????? hehe

I think the line seen here powers my inline pump............ Here I was sad to find mild cancer



after removing the panels I found heeps of dirt, dust, MUD!! DAMN IT.

[JDMJNKY]

Disgusted by what I saw, I whipped out my supplies and got busy. It's just my daily beater but dirt, filth, and down right sloppiness is not how I like to roll. The previous owner probably didnt give a two about this car! which bites.

6 terry cloth towels
2 wire brushes ( toothbrush sized)
1 bottle industrial degreaser
1 can of factory brake cleaner
Infinte amount of elbow grease

so 1 tetanus shot & a few hours later, I was satisfied w/ the results, which I will improve over the next few days god willing.
