re: The 'I told you I'd be back' build of Misfire, my NB2 with F1 inspirationiration

Well I quit my last job before securing a new one because I had several prospects that didn't pan out. I withdrew my retirement, only 5 yrs worth, and that lasted me about 5 months and then I was broke. So I had to partout Warbird so I wouldn't lose my house, etc. Again it was my own fault, live and learn.

I didn't want to get another Miata right away and wanted something rwd, v8 and less than $5k...thus the Mustang. The Mustang just didn't do it for me so thus the NB. You aren't glad to have me 'back', Jameson? :dunno:
i totally understand Chad. I'm always glad to have you back and you're one of the very few i want to stay. Nice score on the second gen. I normally don't like NB's but i know not only will you maintain it and not neglect it but i know you'll make it purdy with tastefulness. :hello kitty:

re: The 'I told you I'd be back' build of Misfire, my NB2 with F1 inspirationiration

sub'd! horray!
Thanks for the support, Ben! :icon_cheers:


Welcome back, subd.
Thank you Ryan! :haiguyths:


Roll bar needs more pink.
Hey are you some kind of mind reader? :claugh:


Roll bar looks much cleaner now. I like it. So, what's next?
Get it running again:suicide: ,currently working on a misfire that I THINK is a/the coil packs. We will see if that is the issue as FedEx delivered my new ones today. If not hopefully the cam or crank sensor that Pat aka patsmx5 so graciously loaned me for diagnostic purposes takes care of it. This build will be more of a endurance race than anything.;)

Reading this feels like the NB version of my car. The m45 is really nice because like you described, it feels quick enough to enjoy but never enough to really get you in trouble. The intercooler and other little bits are neat. I wish my car came with suspension and roll bar stuffs. So exciting!

I had a similar miss when I bought my car, and I went to BKR7Es and it perked up immediately, not sure what set you're going to. Just a suggestion!

I'm excited to see you get another awesome setup and at least you have a nice platform to start on!
Thank you Lindsey! :mrgreen: Don't get me wrong I would have loved a mp62 but I will take the m45 gladly over stock power. I used the bkr6e's, will check on them occasionally to see what they look like. Gary at Track Dog Racing confirmed that with the stock sc pulley and TDR crank overlay it should make 8-9psi, I'm figuring 8psi, so hopefully the 6s will suffice.

Nice! You should look at some GT3/Porsche inspiration too (my 2 cents) since there's overlap with F1 as well.
Thanks Collin! :) Not a bad idea.

i totally understand Chad. I'm always glad to have you back and you're one of the very few i want to stay. Nice score on the second gen. I normally don't like NB's but i know not only will you maintain it and not neglect it but i know you'll make it purdy with tastefulness. :hello kitty:
Thanks, Jameson, I really appreciate That! :hello kitty:

You missed the best interior mod:

Eclipse Vents
Dope! :suicide: I could have swore I listed them...good eye Connor! :D

Do you need another diffuser? ;)

-Henry
I certainly will, Henry! : 3gears: When will your street rear diffuser be ready? :dunno:

But I also don't hear any F1 type sounds. M45 Miata sounds like......a supercharged Miata.
Well that's what I thought of, obviously not identical by any means.... :smile1: ....but just listen to these two as a comparison:

M45 miata

Formula 1 car(from 2001)

Again a SIMILARITY in sound in my opinion. :dunno: I guess it is the gearbox that makes that SIMILAR whine in the F1 car...again not exactly a F1 enthusiast.

YAY! Welcome back! NB2s untie!!!! ;)
Thanks Chris! :icon_cheers:

re: The 'I told you I'd be back' build of Misfire, my NB2 with F1 inspirationiration

04-13-17: Well the NGK BKR6E plugs gapped at 0.033'' fixed the misfire issue for about a day. This time the misfire was so bad it threw it into limp mode, so I pulled the codes which was a P0340(cam sensor) and P0302(cylinder 2 misfire). After some research it seems that the cause could be coil packs, cam sensor, crank sensor or any combination of these.

Since the cylinder 2 misfire had appeared the most and is one of the cylinders with the coilpack directly on and the coilpacks had markings like they were from a salvage yard, I decided to try new coilpacks. I now throwing parts/money at a car to try and fix a car/problem isn't the smartest approach. Honestly if I had/have to replace all three then I count it as preventative maintenance.

Ordered a set of Beck/Arnley coilpacks from Rock Auto for about $82 shipped(had a 5% discount code so was $86) for a pair which was cheaper than one brand new coilpack from a Mazda specific parts supplier. I know how some feel about buying non-oem replacement parts but Beck/Arnley is a well known parts manufacturer. We will see if this was a wise choice.

Received the coilpacks just four days from ordering them....


...you can see the markings I was referring too on the old ones...


....the new Back/Arnley coilpacks installed.


Started it up and it didn't sound right and quickly found a vacuum line coming of the intake manifold was broke, I think I leaned on it, so after fixing that it sounded fine, yay! My enthusiasm faded quickly as I could tell when pulling out of the drive way that the issue was still present and I only went maybe 50ft before trying to turn around and it died twice before getting it back in my driveway. Well that sucks.

I had previously read on another thread about another enthusiast(Cameron) with a FFS equipped NB with a similar issue but his turned out to be frayed wires(making contact with a belt/tensioner) but I checked mine and while the plastic wire loom had a place where it was damaged, the wires look to be fine.

After ordering the coilpacks I was 'thinking out loud' via email with Pat aka patsmx5 and he was kind enough to offer a spare cam and crank sensor for diagnostic purposes. Within 45 minutes of him offering he had a tracking number for me! People like Pat is why this community is so great. So those should be here by tomorrow but I won't be able to get to trying each out until Sunday. I REALLY hope it is the cam sensor(it did have a code for it after all) since it is one bolt and takes a few minutes to swap since it is on top of the valve cover(99-00 on the front, 01-05 on the rear).

I also picked up a piece to match my Project G Precision Series oil cap....


....Project G Precision Series oil dipstick(currently out of production) intended for a broken oil dipstick. If you look at one of the pics above you will see mine is not broken, which is crazy because my last two Miata's it broke. So I will just have to get one that is already broken to use this beauty.

Thanks to Eli aka Hyper for selling/shipping it to me when he could have sold it locally at the MiataPalooza event but I had contacted him prior to the event but hadn't finalized everything so thanks again Eli! :icon_cheers:

No way, you're the one who beat me to this car lol. I test drove it a few times and was haggling the dealership (even though it was already a steal). Nice score man!

YESSSS back in action again!
Thanks, Seeing! :icon_cheers:: 3gears:

Mustangs drool, Miatas rule!

Welcome back. Sweet pick up on the car. Very jelly on the supercharger.
True, true! :ibtl: Thanks, it is fun when it runs.:smile1:

Please tell me you aren't the person that they told me was calling everyday and offering like $100 less than the asking?:lol: Don't feel too bad it has only ran 3 days in the last two weeks :suicide: ,chasing a misfire/idle issue. Found multiple vacuum leaks and think the maf is bad, which I have one that should be here today.

haha I was offering them an out the door price, cash only for toys and I like even numbers. They clearly didn't like that but no harm no foul.

Main reason I was doing that is because auction cars always need some work, but hey a maf and some vac lines isn't too bad in the big picture, hope you get it all sorted!

Understandable. Looks like the solution may have been even cheaper(more or less free) than the cost of a used maf and vacuum lines... :suicide:

re: The 'I told you I'd be back' build of Misfire, my NB2 with F1 inspirationiration

04-24-17: Since I brought the nb2 home I have had a 'miss' that turned into a full blown 'misfire' and caused it to be parked for the past two weeks. One step colder plugs fixed it for a day, new coil packs did nothing, tried replacing the cam and crank sensor with good used pieces...they did nothing.

Then the week before last, when working on it I found this...


...that is a very cracked vacuum hose that went from the supercharger bypass to the throttle body. The cracks SEEMED superficial but I had the vacuum line so I replaced it...


...it seemed to idle better. Took it for a drive and it drove fine! Well that lasted less than a day!!

Then I decided to start hunting for more vacuum leaks. Bought like 6 feet of several size vacuum lines, some carb cleaner and started spraying....nothing. Then I got inside the car and heard what sounded like a vacuum leak....then it struck me and I got under the dash and found this...


...may be hard to tell what it is but it is the vacuum line that goes to the powercard and it had a small split just above the nipple it attached to. Cut the end off but couldn't get back on! I actually had to remove some of the plastic for the hole that the nipple protruded thru to get enough room for the vacuum line to go all the way on.

Easy enough...then I started it again and STILL heard a vacuum leak! Looked around some more on the inside and found this...


....another vacuum line with just a piece of electric tape at the end that had been tucked up under the hvac! It probably went to a boost gauge that is no longer there so I decided to just plug it for now. Started it back up and still these fault codes persisted...


...that was it for that day, as far as trouble shooting goes but I did find out I needed a new air filter....


....it was actually worse than it looks. Once removed the metal seam fell off and saw that the neck that a hose clamp would normally hold it on had been cut off and it was simply slipped on!! My bad.

Then last Friday I removed the plugs and found that the number 2 cylinder plug looked brand new as there was almost no carbon on it, unlike the others. So it wasn't getting spark and or fuel, thus the misfire. Pat aka patsmx5 has been helping me trouble shoot and he suggested I check the wiring for the powercard after seeing the plugs. Ironically this is exactly what I was doing as he texted me.

I tugged on one or two of the connections and one of the wires came loose! It was a purple w/ green stripe, I had no doubt this was for the number two fuel injector. After a quick Google search and no wiring diagram for the nb2, I knew Pat would have one. Sure enough he did and emailed it to me and sure enough that wire was for the number 2 fuel injector!

The soldering job was less than adequate and thus the wiring coming loose and seemingly causing the misfire issue. Unfortunately I was going out of town that evening and had to call it a day.

This evening I was able to get back at it and fixed that wire connection for the powercard. Started it up and still it had a terrible idle! Checked the fault codes and this time it said there was a misfire on cylinder four!! So I went ahead and redid the connections for cylinder four and three fuel injectors as they seemed flimsy but left the one for cylinder one fuel injector alone as it seemed much stronger and it had already been cut close to the ecu connection and didn't want to risk not having enough wire to fix it.

Started it up and it idled(and revved on occasion) great for about 15 minutes with no misfire code returning! Unfortunately I couldn't test drive it given the absence of a air filter and couldn't find one locally as it is a 3'' I.D. that is only 4" long and just over 3" wide. The DDM Works supercharge intake box originally came with a UNI foam filter(#UN-4300) so I just ordered a 2 Stage version of eBay, so hopefully it will be here this week and I can confirm the issue has been resolved.

I also received a broken oil dipstick from Mike aka chiefmg to mate to my Project G Precision Series dipstick handle, big thanks to Mike for sending it to me and he wouldn't even let me cover postage! Thanks again Mike! :icon_cheers:

Heavens that was a rollercoaster. Seems like there were a fair amount of gremlins living under that rather decent exterior! I'm curious to see how the drivability is with the piggyback ECU with moderate power levels. According to certain forums your car should have blown up long before now due to the lack of a Megasquirt.

Welcome back! It was sad seeing you part out Warbird but I am looking forward to what you have planned for the NB. I know it will be awesome!

That is crazy about the air filter. I have an AEM Dry Flow filter I'd happily send your way but it is 5" long. :(
