Long Tube Headers (N/A application)

Do you know what you are getting into? The right side takes about 1 1/2hrs. Start to finish. The left takes about 6+ hrs, depending on your pain threshold, mental fitness, alcohol consumption, and if the neighbors call the cops on you for cussing in public.

What I am getting into? hmmm....a little background on me:

While I haven't felt the need to re-certify I was an L1 Master Certified Tech, been wrenching professorially since 1995 (other than a 4-year stint I spent serving my country and another 3 year spell I used to get my BA in History), and currently a shop foreman at an independent out in VA. Some other personal exploits entail a pretty extensive set of mods to my old 98 cobra (Complete GR40 suspension install, Supercharger install at one point, NA 11:1 F/S engine build, setting up a dual runner intake on it, and tunning said mill) and I've also worked on everything from Honda Civics to Bentley Conti GTs to include a power plant pull on an RS6.

So, yeah. I think I know what I am getting into. That being said, I would like to know if the Motordyne require modifications to the coolant system on my 15, as the FI setup does.

Lastly, thank you for your concern and for the heads up that it might be a slight PIA. I wasn't expecting it to be a walk in the park.

Rusty

Good for you. Most people who do the LTH's don't have your background. So the right side should take you about 40 minutes, and the left side about 3 hours then. The heat shield on the left side exhaust manifold is a PITA to get out. The steering shaft may give you a fit when reinstalling. The joint is key-splined, so it only goes on one way. The issue is there is a sensor ring on the rack input shaft. If that gets moved. You might have the slip light on the dash to come on.

I don't know about Motordyne LTH's.

My background. Used to be ASE Cert Master Tech too. Cert welder. Degrees in crimmeral justice, welding engineering, and mechanical engineering. Built, maintain, and ran a natural gas fired combine cycle power plant. Retired from there as a CRO.

The SAS is on the rack itself? We've done a few Gs and a murano just the other day (racks) and they weren't set up this way. Don't work on too many Zs, but I don't recall that being the setup and is kind of something I haven't seen yet on any make. Normally the SAS is on the column somewhere. Anyhow, thank for the heads up on that. The SAS is something that we end up recalibrating quite a bit on various makes (sometimes our screwup and sometimes from other shops), but what I really stress to my guys is the Clock Spring. I always make sure they lock the steering wheel with the seat belt, as if that wheel moves too much (e.g. a complete turn)then you can stress that guy and give yourself fits with Supplemental Restraint System issues. Again, thank you for the tip on the rack and i'll be sure to take a closer look at it.

Also, if I can get that job done in under 5 hours, i'll be ecstatic. I was thinking anywhere from 4-6 hours just off cursory glances. Good thing is I garage this guy and don't drive her in the rain. Absolutely hate how much Nissans rust. Especially the exhaust.

Rusty

If you got fat hands. They might look like they got in a fight with a pissed off putty cat. There is lots of screw and bolt ends sticking out on the left side.

So you retired when you took the job....did all that and couldnt stand it...Coming from coal fired the gas was boring...

Rusty

Nah. Came from a company that built and repaired rotating equipment. Steam turbines, gas turbines, compressors, pumps. Got hired at the power plant when construction first started. So was there from construction, commissioning, start-up, and going commercial. I know where all the dead bodies are buried at. Know all the short cuts that was taken to get the plant up and running. I was number 1 on the seniority list. I retired as senior control room operator at the age of 60. I've had my share of coal plants. Repairing equipment in them. Coal dust everywhere. Been in nuke plants too. Don't like glowing in the dark. I see you're not too far away from our sister plant in Beverly Ohio. You at the AEP plant?

As far as any modification, I didn't do the install myself, but my mechanic didn't mention any modifications he has done, only thing was the pre cat sensor which was welded to oem manifold. So, I had to buy new sensors. Also, you will need either a 20 guage wires to extend the pre cat sensor wires or an extension link, as motordyne will not provide them.

Just went and checked on FI's site and it looks like the mod is for 12+ models as something changed with the coolant crossover pipe that doesn't allow the driver's side header to bolt up.

When I did headers the first time on my Cobra I had to do the same thing. Wasn't a fan of it and would rather run extenders if they exist. If not, I might just make some myself.

Thank you for the heads up on the wiring i'll make sure to have something ready before I start if I go with the Motordynes.
