How To: 2.0 Header Installation

[GMalatrasi]

Nope... Airbox it still there.
I think it might actually still be the EGR fitting.
I'm gonna spray some soapy water on it first thing in the morning (when it's still cold) and see if it is the EGR.

^^ good idea, but the header gets so hot so quickly that I bet the soapy water will just evap .. have someone else start the car so you can be watching right as the engine starts.

 

[GMalatrasi]

Yup

Hey guys,I'm tryin' to install my OBX header in now but I'm having trouble w/ the two spring loaded bolts holding the midpipe and the pipe coming of the 1st cat together and the "mount" that holds the first cat in place.I can't seem to budge any of the bolts.What did you guys use to take them off??

Impact wrech

You can also try using a loosening agent like wd-40...

PB blaster then brute strength. Break bar always helps too.

Gee,if only I had one,(lol2)

But yeah,breaker bar didn't help much since it's too long.

Anyway,I'll try the WD-40.

Thanx guys!

When I put on the OBX header my problem was that the bold came out, but the nut was stuck to it. I could not get it off with anything until I finally tried a blowtorch. Got it nice and hot and it easily came off with a wrench. But since yours is stuck under the car I dont know if you want to have a flame under there.

Ah,u used the blowtorch/perafin method.Yea,not a good idea w/ the spring bolts(lol2).

I bought myself a christmas present (a new OBX header) and decided to install it today. I would've been done in less than 2 hours but I ran into numerous problems.

The EGR didn't line up (and still doesn't) and I snapped a bolt off in the head.

I will give further details and pic later.

For the EGR pipe ... mount the header up with a couple nuts threaded a turn or two (loose, but so it won't fall off), snug up the EGR fitting and then tighten and torque the header down.

 

[Lord_Zath]

yeah if you wait to do the EGR last, you won't be able to get it on right.

A member here actually slammed a crowbar into his radiator trying to get that EGR in so be careful!

 

[Thekid760]

I'll try that with the EGR. Here's a pic of how far it's off. It's not much, but no amount of prying/heating would allow it to line up.


As far as snapping a bolt off in the head, what do you suggest? I used my torque wrench set to 15 ft/lbs just like i did with all the other bolts, but this one snapped right off about 3 treads from the head of the bolt. Whats really comfusing to me is that they are all grade 8 bolts, they shouldn't snap that easily. How do I get it out? Here's a pic:

 

[Thekid760]

Woo Hoo! I finally got the EGR pipe to connect, I had to heat the pipe up at the bend near the TB and pull it out to give me that extra 0.5" I needed.

It sounds so good and drives so nice. I love the extra power and improved throttle response. The butt dyno tells me I have arounf 5 extra hp.

Has anyone dynoed their car before and after header install to see the gains made?

 

[cplagge]

I just got mine installed, and after a long 3 hours of getting it to fit right, i plug the battery back in, turn the car to the on position, turn the ignition, and....!

it turns over, wont start i am so pissed at my car right now. Does anyone have any ideas what to look for, to see if I accidentally disconnected something while installing the header???

 

[kudakev615]

does it try to turn over? or does the starter just click when you go to start it?

 

[Laser03pro]

Are the battery cables good and tight? NM you said it turned over right?

 

[cplagge]

Turns over, does not start. cant think of anything around where i was working that would cause it to not start! but i am tired and prolly not thinking straight
