Am I ready to install my headers? - ZR-1 Net Registry Forums

MuRCieLaGo · 03-02-2016

Ok, from now on I got:

-Exhaust manifolds gaskets
-Paul's dipstick bracket
-OBX headers
-Patience

Haven't received the headers yet though, will I need to have them surfaced?

I will also need to order a chip from Marc Haibeck.

Do I need something else? Bolts? o2 harness extension? Permatex?

Thanks!

Yes. You'll need that too!

Paul, I'm not sure what you mean by "that".

Bolts - YES
O2 Extension - YES
Permatex - Always good to keep on hand

Dipstick grommet from Jerry (unless you're very careful & lucky)

My 94 did not need O2 sensor extension. I believe OBX headers, due to fake cats, O2 sensor bungs are 3-4 inches forward compared to Stainlessworks headers.
Any other OBX header users remember different?

Also, I used Permatex high temp copper sealant per Phil's recommendation. Seems to help the seal and keep the bolts from vibrating loose. Although I used Stage 8 bolts with locking tabs, Phil's suggestion was not to use the locking tabs since header gasket tends to shrink at times necessitating re-torquing of header bolts - impossible once locking tabs are used. However, there are two bolts impossible to get to once dip stick bracket is installed. For those bolts I used the locking tabs knowing I won't be able to re-torque.

Hahaha! Jeff made it very clear.

BUT,

Will I need to surface the headers flanges? It hasn't been answered yet.

And thanks Demps for the grommet tip!

My 90 needed O2 extension.
My stage 8 fasteners, the locking clips would not fit in the groove, so not locking. In my case they served no purpose making for some expensive header bolts.
I also ended up shimming the engine at the motor mounts to clear the steering shaft, the ceramic coated headers rubbed the steering shaft.

I cannot answer that as I had purchased used Watson Headers and just bolted them on..
