Am I ready to install my headers?

[RussMcB]

I think I read surfacing flanges wasn't needed.

My OBX headers (without fake cats) did not need O2 extensions, but that may have been because I used O2 sensors that were recommended because they came with longer leads. Sorry, I don't remember the brand/part #, but I think I got it from zr1.net/forum.

I didn't bother to coat my headers. That would probably lead to longer life but I figured I'd give the original coating a chance first to see how it held up.

I also needed a dimple and engine mount shim to clear the steering shaft.

One thing I liked about the Stage 8 bolts is you also have the option to screw them in with an allen wrench, useful to get bolts started in some of the tight places.

I didn't coat my OBX headers either....I did wrap them though with titanium exhaust wrap...The wrap does not need to be wet first...It goes on well and you can pick it up on eBay or Summit...

Coating can get expensive from what I hear...My ZR1 is just basically a pleasure car so it really doesn't get a lot of miles or is in bumper to bumper traffic each day where underhood temps. could be an issue...

Thanks for all the answers guys! I got pretty much everything now, except for o2 extension harness. Some say I'll need one, some say I won't.

These are the OBX I'm ordering:

And if I need an extension harness, I don't know where to buy it.

And by the way, the reason why I want to make sure I got everything is because I will have everything shipped in Maine and I'll travel 2 hours each way (+ customs) to grab my stuff (I live in Canada).

If you are somewhat handy you can fabricate an extension using this kit and some wires.

I still don't think you will need one but to be sure...

Alright or I can go to a local scrapyard and build something from there! Thanks a lot! I think I got everything now!

I just searched for 10 minutes looking for the O2 sensor part number with longer lead, but couldn't find it. Maybe I saw it in another forum.

Not sure if it has been mentioned here, but you'll probably need to buy two packages of the Stage 8 bolts because our cars need 32 (or close to it - you can get by with fewer). I bought two packages and may have a few left over laying around. Maybe you could get me and others to ship our left over bolts to Maine for you. :-)

2 packages? Oh my god, will it ever end?

Hahaha that'd be funny, 8 packages of 4 bolts each?

Is it where the air injection system goes? What if I remove it?

[Demps]

EGR pull off.

Only only 93-95 & I'd remove it then.

Alright then I'll go to a local welding shop to remove that port.

Thanks!
