I just want to tell you thank you dad!! I started watching your KZbin since broke and boosted, you've motivated me so much and influenced me to build the hell out of my miata, I've had the car 3 years now, boosted for 1 year and recently blew it up, now I'm rebuiding all back up, I couldn't be more excited, I had a rough start of the year, it felt like life kept pulling me down, especially when the car blew up, everytime I lose motivation and feel like I can't anymore, feel like giving up, I always go back and rewatch the rebirth videos, and now videos of your 500hp vvt beast! you really have and keep pushing me to keep going, keep working on my dreams, and never give up, so I just want to thank you for being the best miata dad, you have helped me through so many rough patches, I just thought I'd tell you how much you've helped me and keep re motivating me!

The zip ties are typically nylon which seems to hold up pretty well submerged in E85. Just make sure the metal hose clamps are good stainless ones.

Very well explained as always sir, well done and congrats on doing such a fine job. And very impressed you stuck to your word over 2.5yrs after I did this, I'm honored to have been mentioned :-)

[@ChandonP]

I hope you're using fuel submersion rated crimps and hose (SAE J30R10) :) The fuel hose you took out looks to have degraded consistent with non submersion rated hose.

[@roboman2444]

Those hose clamps may rust over time in the E85. Zip ties may be a more reliable solution, and have proven to last in E85. Why not both? Redundant materials.

[@OGPedXing]

Great job. The only issue with that fuel filter setup is what you saw... it's common for a line to give out at the filter due to the restriction there and if the filter is in your engine bay there's a higher chance of a fire. Just keep up with maintenance of the filter and inspect the lines periodically and you should be fine.

Good call out with the Id1300s and the skunk2 manifold, I plugged the adapters in and then installed the injectors, but it was still very tight and I was worried about getting a good seal. No leaks thus far! Cant wait to see this thing make 500whp!

Bro I promise you were a big part for me to buy my nb... (bought is 3 cylinder and fixed it home! Never fixed a car before appart from maintenance) ...and man I love your car as much as mine so much that I'd like to see it bit better protected from corrosion (even in my nb that was the first thing to do and I still got some more road to do) ! So that's a friendly reminder to fix every spot of surface rust !

[@seth-7713]

Something I learned after the fact for mine is an additional safety measure to using a crimp with heat shrink is to splice in two different sections for each wire, that way if they were to ever be exposed they are even less likely to contact the other wire. Maybe it'll be helpful to someone else before they splice into theirs.

Blew my main relay after about 8/9 years with a larger fuel pump (for those who don't know, the main relay feeds power to the fuel pump relay.) I hit the easy button and got the higher amp relay out of a MPV. ($7 at a junk yard vs $80ish brand new online) I also have this hard wire kit ready to go, since June, but SCREW GETTING UNDER THE DASH! Planned on doing mine the very same way. Happy to see it's just as easy as I thought but now I feel bad for how I keep putting it off. Ready to see that 500+hp!!!!

[@bentracy7463]

Fun fact, rising rate and boost referenced fuel pressure regulators are not the same thing (16:45). Rising rate is generally not linear (so 1psi of boost may be an increase of more than 1psi of fuel). Boost referenced are always a 1:1 relationship, although often this will decrease to 0.8psi fuel to 1psi boost or so at 20-30psi of boost pressure - it depends on the regulator itself as to what point that changes. Anywho, just wanted to mention that quick tidbit. Nice video.

I had a similar problem with my VVT engine dying at startup, and it was because the activated VVT was adding more air than the WUE was set for. I combat this by deactivating it till WUE ended.

Be careful with vasoline. I found out that it can make rubber O-rings swell. (Bathroom sink, so it may not apply to the injector O-rings). I always now use dielectric grease (like for sparkplug wires)

[@michaelswitzer9220]

Obviously it works, obviously it’s fine. But there is always something about connectors sitting inside the fuel that will always weird me out. Electricity hanging out in a flammable liquid. Sounds great. 🤣🤣 Nicely done dad, bring on that 500 HP!!

[@s.willis8426]

Even more fun to think about how the fuel cools the pump. Always running on a low tank is a sure way to strain the pump into an early death as it overheats without being surrounded by liquid (flammable liquid in this case).

[@dreammakergarage1133]

Yeah ran out of pump at 445whp. Was running an AEM340 going bad. Now running a Hellcat welbro525 pump. 2200cc injectors.

One correction to point out - what you have is a MAP referenced 1:1 FPR, not a rising rate. A rising rate would increase fuel pressure MORE than manifold pressure, say at 3:1 ratio or more

Hey man I love you videos and have learned a ton from all your content. Question for you ... What fuel line are you using with the E85? And have you noticed any of it deteriorating? I'm making the switch to E85 on my MS3 S480 turbo 460 bbf and curious about fuel line. I'm currently using the Jegs Pro-Flow 250 stuff which had been great so far. Thanks!

[@TheCarPassionChannel]

I've been using standard 7.9mm fuel line, nothing special, the lines that I showed having issues in the car have been in there for 6-7 years of pure E85. I should probably convert the whole fuel system to something better, but I really haven't had much trouble so far.

[@johnvirgilsgarage]

@@TheCarPassionChannel that's really good to hear some real world experience. I keep being told that my lines won't work with E85 but I bet they would be just fine and if they last 7 years I'd be happy with that. Keep up the good work brother, you are killing it!

[@jestenvick12]

I have a similar set up for my 1995 turbo Miata, I went off the same signal wire for my hardwire relay, works fine sometimes but other times I’ll be driving and the stock relay and the hardwired relay get hot and then the car starts to run weird, any ideas?

[@EMSzero]

so i turboed my car and i put a stronger fuel pump in and it was working perfectly fine until one day it didn’t. i replaced the stock fuel pump relay and still nothing. I already tested my fuel pump separately and confirmed that it is good. would this fuel pump hardwire kit fix my problem ? personally i would think so bc it would be getting its power directly from the battery but just a question for you greg and anyone who happens to see this. Thanks and have a great day !

[@WarWolfX1]

On the factory fuel relay, jumper the wires.

[@111dontworry]

I bet if you bypass the stock fuel lines and go with larger AN fittings instead of the restrictive stock stuff, I bet you won't have any more fuel issues.

[@joelhernandez393]

I'm about to do this and am a little confused. You cut 2 wires at the harness before it connects to the fuel pump (the power and ground). I get the part where you split the blue and yellow wire one going to the pump and one going back to the relay. What I don't get is why you cut the ground wire and capped it? I'm not saying it's wrong I'm just seeing other ways people have done this and they said all they did was cut the power wire and connect the blue and the yellow wire. I think in the directions it just mentions splicing into the power and not cutting 2 wires (power and ground)

[@PhuckingMagikal]

Do you know if there is a downside to not snipping the ground wire in the wiring harness for the fuel pump? It's just an extra ground, yes?

[@reyes1987]

I had the exact same question. Going off Deatschwerks procedure, it doesn't even mention snipping the ground wire. The ground wire from the new relay is essentially just meant to ground it. The existing ground should be sufficient.

[@TheMapleDaily]

Hey Greg, I wanted to ask how much your car weighs after all the mods. With you making 500+HP and depending on your weight, you are the definition of mustang killer! Also Miatadad, does my laundry list before I turbo sound good? 1. Bushings all around, 2. Coilovers, 3 Torsen Swap (1993 LE, so it came with a vlsd 🤢) 4. Standalone 5. Turbo! I am looking to make a reasonable 140-200, I also already have ARP head and main studs. I want to be able to keep up with traffic and have some fun with turbo noises. But I also want to be able to corner amazingly! What Power number would be reasonable to allow me to corner just as good without overdoing it? (I also bought my miata with some weightloss apparently.. owner removed AC and PS for manual rack..

[@fiisho]

If you're only making 200 a simple turbo setup, and maybe head studs would be more than enough. But I think if you really want, do rods, maybe pistons, and go for a good 300

[@91ludesit]

Why so high on the base fuel pressure? I thought 43.5 was the normal base.

[@Shadowfax2121]

Buddy, that fuel pump is just pre-meditated upgrade for your 35hp WET SHOT nitrous to spool the turbo up faster. Read up on it, it's safe just cutoff at 8-10psi during WOT only - the bottle should last a LONG time under this scenario.

[@TheCarPassionChannel]

Real talk - if I was going to do a nitrous spool setup I'd definitely go +2 sizes on the turbo. This thing doesn't leave me wanting any faster response. With spray it would be sick to have something that could spool as fast but actually be able to breath/be efficient at 500-550. This turbo is having its neck rung at 500 😅

[@brendanaiello]

What roll bar is in this (red) Miata?

[@TheCarPassionChannel]

Hard Dog Hardcore X-Brace

[@dreammakergarage1133]

Wow. 60psi at ideal. On the 2200cc injector. My fuel pressureat ideal is at 40psi.

[@TheCarPassionChannel]

ID injectors supposedly spray best around 100psi, so 60 base + ~30psi boost (1:1 reg) gets me pretty close. Stock base FB on the NB motors is around 55psi

[@salloroc20]

Wait a sec. You're still using factory hard lines for fuel? I imagine you're probably pushing your pump an extra 20psi higher to make up for the pressure drop lol

[@LiveToRidee]

Greg I followed you from the beginning when I bought my completely stock NB in 2016 I had practically no automotive knowledge too... Now I've got $15k+ into the car w/ a built bottom end making 380whp and I did all the labor myself... I'm torn though; do I build the head and do the ZF/getrag swap (approx another 5k+) or do I just part out and go LS. I could see 500/600 doing the head. My rear-end and trans is a ticking time bomb right now anyways as they're both stock. What do you say?

[@TheCarPassionChannel]

That's awesome to hear man! That's a tough call, but I think in the end you'll likely be more happy with the LS if that's the power level you're going for. It depends what you really enjoy, if you really love that turbo 4-cylinder action maybe build the head + turbo upsize or whatever it takes to get you there, it's just always going to come with unforseen issues as the power goes up, as you might already know. Good luck with whatever route you choose!

[@LiveToRidee]

@@TheCarPassionChannel thanks alot Greg! I appreciate the quick response. I do hate giving up on platforms and I do love the turbo BP. I guess I'll have to continue giving it thought. By no means do I have tons of money laying around LS swapping won't be something I could do easily financially. Ultimately I've got a running car now and LS swapping might put it out of the game for awhile. Thanks for the insight!

I want to see your car lined up with something else. I just cannot fathom it putting down this level of power I just feel like a 400hp Golf R will still manage to gap it lmao

[@s.willis8426]

I think the 2 weak points of any high powered miata build against other cars is traction without weight and the gearing of the transmission. 4000 lbs cars can roast the tires with 500hp, trying to keep a 2100 lbs car from doing it could be damn near impossible. Then you need a gear ratio that allows you to maximize that power for your intended purpose, stock NA miata gearing requires 3rd gear just to hit 60 mph. I know he's not a stock transmission anymore but without really customizing the gearing it's a weak point for the power delivery.

EDIT: Found the solution. Check my reply. It seems to be rushed over in the video, but where did you get the connection for the blue DW wire from? I’m trying the install and don’t know where to source a switched wire from.

[@dilberadam]

Nevermind! Figured it out. Yellow on the DW piece connects direct to the blue/red factory wire on pigtail side (goes to fuel pump) and the blue connects to the other half of that blue/red factory wire (goes to the factory fuel relay). Thanks for the video!

[@PhuckingMagikal]

@@dilberadam The one thing I'm curious about is if it's essential to snip the existing ground wire or not from the factory harness. I'm tempted to leave mine in tact, but not sure what havoc that could cause.
