I thought the hole to route the nitrous line was already there but grommeted.. I was wrong? I was also confused about how I was gonna mount the bottle anyway...

subscribed... I'll be taking the plunge with the help of Charles in the next month or so. Great stuff already... please keep the photos coming as you make progress.

Got my bottle heater today.

I'm going to just grounding it in the trunk and running the power line to the a switched +12v line I have in the trunk for my carpc, that okay Charles? This way I don't have to deal with running a switch into my cabin or anything.

Also anywhere in specific I should mount the bottle heater around the bottle? Is it okay if the heating element is going over the paper label on the bottle? Is wrapping it around the label area fine in terms of bottle position?

I'm hoping to get this finished on Sunday. Sucks I have to work the next few days and the weather is FREEZING! It's -4 with the wind chill right now, brrr.

PS: I also FINALLY got my hands on a used Mazsport Midpipe so hopefully I'll be getting it in sometime next week and that will make an even bigger difference in overall power.

Al, any idea of how many amps the heater pulls? Sounds like a good place for me to tie mine in as well but my little carnetix psu can't handle more than maybe 5 or 6 additional amps... I'm guessing no more than 100 watts @ 12V.

In the paper that came with it, it said to make sure that any circuit I'm tapping into can hold an additional 15 amps.

could you not make a bottle mount in the back of the plastic thing that goes between the rear seats?

Then you could pop it out easily for access?

I think the bottle he's using is a bit bigger than the center cargo carrier and I suspect he already has PC crammed in there anyway.

Hells bells, so I'm either running power from the battery with a switch or upgrading my PSU.

yeah, it's a 10lb bottle.. pretty big. the bottle has to be bracketed a certain way with the valve down and so that the pickup line inside the tank doesn't suck up air during acceleration.

chris - you had your bottle mounted on the frame right? upside down by where the Bose amp is? that seems like it's going to be a pita to get the bottle strapped up when it's full and 25lbs. I'm thinking of bolting it down where Charles has his for ease of access.

shelldude - I think I'm going to have to run a new switched line from the fusebox to accomdoate 15 more amps.

Planning stages right now. I need to get busy on this.

So is the hole already in the trunk, or no?

I'm talking about this one (not my picture):

nope, you have to drill another hole... if you pull the liner back you'll figure it out really quick.

I have my tank mounted to the speaker shelf as well and it was a pain the first couple times but I figured out that it was a lot easier (for me at least) if I strap in the bottom first... once I figured that out, it wasnt really hard to get the tank in. I personally like the way it is now because it's there but out of the way and unless you actually look because the trunk opening doesnt really show it from a standing angle.

depending on how good you are at these things (or how often you do them) it might seem like a pain in the *** but it's worth it lol... I couldnt drive my car for like 4 or 5 days cause I couldnt set aside enough time any one day to get enough done so it took a while lol.

Oh.. if I had the time and everything I needed over last weekend I would have done it all then. However, I did not. I couldn't source a good replacement fuel hose at any auto parts store so I bought it online and am soooo hoping it comes in tomorrow. Then I also had to work these days.

It's been good though since I've caught up on other tips and what to look for. I know exactly what I'm going to be doing when I get a chance too. Hopefully Sunday.

On top of that today I find my cars fender is dented pretty big in two places.. some ******* decided to pull a hit and run. Ugh, I hate the world. Good thing it looks like it can be easily knocked out but the paint is a bit scratched.

Messy in what regard? I completely replaced my fuel line hose.. so my stock fuel line wasn't cut.

So today I did it all except for drilling and mounting the bottle in the trunk. Programmed the ZEX module.. however I noticed that solenoids were clicking at a tiny bit less than WOT.. is that normal? The stock rx8 ECU reports the throttle position to my obd2 scan as 0-67% (not 0-100%) and the module solenoids were clicking at 60%.. normal?

Getting the upper intake manifold off was not bad. I got scared a few times when fuel spewed everywhere while getting the stock fuel line off.. it still had a bunch of fuel in it. Then later on I found I had a fuel leak at the elbow fitting where the hose was connected to, not the side which screwed into the Tee fitting. I sealed the Tee fitting with a gasket sealer adhesive - that isn't leaking anytime soon. I used the leakage test in the rx8 service manual. It is very tight under the stock air intake box with the fuel/nitrous inlet hoses. It all fit however. One thing I will HATE doing is getting the stock airbox in and out. The BHR spacer added an inch or so, so getting that stock airbox in was a CHORE, ugh. I also broke one of the plastic elbows that hook up the vacuum hoses to the accordion tube. I routed the nitrous line under the car through the canal that is already there, as Charles has done for all his other installs. I will have to thread the hose UP into the trunk hole that I drill.. I worked backwards I know :|. I drove around hard for a bit to "pressure/leak" test the fuel line tap and stuff.. and so far no leaks.. hope it stays that way!

Getting pix up in the second and third post of this thread now, go see!!

From my experiences it reads 67% at wide open throttle. Mine hits that number then drops a little bit to 66.8-9 %. You might try resetting it and see if it comes on more toward 67.0 %.
It's reading voltage at the TPS at that WOT point. So it just means it's reading max voltage a little sooner than WOT. Try resetting the ZEX module.
