greg, my dude, i love watching your vids. i gotta say, you've got the patience of a lion turtle. if something on my car broke every-other time i turned it on......
I've heard people in the civic world say that the hard fuel lines are only capable of X amount of HP and fuel flow. Thry say eventually you have to upgrade to a larger diameter hose to support larger fuel systems. Is there a known amount of fuel that can be pushed through the miata hard lines? Or is it something way above what you are planning on making?
I'm sure at some point there is a limit. Online sources say the 5/16 line should be okay to 600hp, for 99.999% of Miata owners including myself the lines will not be an issue
Another great video! I wouldn't have been able to build my miata in my garage without your vids! I am running high compression 10.5:1 BP4W with the 6758 and a built head with 10mm lift 264 cams. Seems to be fine with the ID1300s and DW 300 for fuel thus far. Running about 30 psi currently, spins the tires in 4th sometimes!
Fuel pump/regulator dying is one of the things that haunt me in my dreams (alongside of timing chain/ tensioner failure), have you checked the compression for peace of mind?
@@R03333 Depends on when it happens. If it happens when fuel is needed the most, you might melt pistons/rings/valves and that also can result in a chain reaction of catastrophe. If it happens while idling/under vacuum, there is a good chance that you might get away with it.
I've been watching your videos since your first motor blew up after the I think an intercooler pipe blew off during a Dyno and threw a rod on the way home. I don't have a boosted vehicle but you've helped me with just general engine knowledge the new engine sounds like runs pretty good! Keep up the great work
Hey Greg, amazing video. Congrats on the new power figures! Crazy to think how fast it would be. I was curious about how your knock readings are at such high levels of boost? I know the corn juice would help a lot with pre det. Thanks!
I need to stop watching these videos, because now I want to buy another Miata. Love the content, and the tech section at the end was just as entertaining as the pulls in Mexico.
Went to buy a valve to match my cam gear from your original 1.6 build but they are all sold out 2 hours later! It is awesome to see this channel grow! Keep killing it Craig!
Hey Greg so I have an 04 MSM and im finally doing a rebuilt on the engine but my question is because the Mazdaspeed comes with a hard line for the oil feed and water do I need to upgrade the lines if im going more than lets say 450hp?
Nice video again. Pls don't slow down on the free content. That exaclty the reason I don't use any ad blockers. That little bit that goes to the content makers actually happens because people still watching ads
I'm new to Miata world and will be getting one soon. Just was wondering if this was a 5spd or 6spd. And also what diff? I love how these gears are short but not tooo short. I'll be getting an nb Miata and will be building the motor and boosting it. Which diff is best for boost?
Love your videos! Rare mix of doing stuff right and explaining it well. Have you considered a dry sump? It could both be a cool tech to dive into and also help protect your engine at high Gs. Oh, and add a few percent power, which, at your level, would actually be quite a bump... surely pushing you past 510 :D
👍👍👍👍👍 love it. I know when i was going through Hyundai school this was a bit confusing at first, but once it clicks....makes like much easier to figure out. Love the content, keep up the good work.
Man, talk about a timely vid... Just finished my supercharger upgrades. 150mm crank pulley, 65mm nose pulley. 312cc injectors plus a 5th 550cc throttle body mounted injector (fires 1x each spark fire) and progressive (50/50) water/meth injection tapped into the intake. Max is now 24lbs boost, and AFRs are rising from mid 12s into low 13s past 5500 in 4th. Installed Deatschwerks 255lph fuel pump is rated 40psi but I didn't even think about the 24psi of boost fighting the rail! If I add more fuel it bogs... Less and I get knock. Trying to find that "sweet spot"!
@@hdhellion4128 My supercharger setup is cold sided, so the best options are to drill and tap the manifold pan or spray pre charger. The former can hydrolock your engine if anything goes wrong with the injector, so I decided to go the less risky route with pre charger injection on the intake. The incoming blast gets diffused by the blades perfectly. I placed it about 2 inches back from the supercharger air inlet.
@@hdhellion4128 The MP62 blades do have a teflon-like coating that will erode over time with meth use, but that alone can't destroy the blades unless you ignore serviceable parts like the coupler and needle bearings. I just replaced the coupler for $15 and cleaned and re-greased the bearings and no balance issues - i.e. the blades are not hitting each other or the inside casing. Dumped in a $12 bottle of SC oil, and good to go. Took an hour to do everything. I'll probably wind up doing that about every 10k mi since the meth is pretty effective at removing grease too, but it's a small price to pay for the incredible reduction in IATs.
Amazing results, dad! It's probably horrible to do, but a summarized cost of the complete build as for all parts needed would be interesting (exploded parts excluded, I won't be trying them anyways :D )
Wondering how many miles are on the current motor. This is still basically the engine rebuild you did several years back I think. Been out of touch this year. Left California but I now own a huge piece of land and house.
@@TheCarPassionChannel I knew that build would stand up to some challenging load bearing. In the state I live in now, I have seen only 3 Miatas. Roads for miles for cruising. Thanks man.
Understandable that you don't want to run the 500whp tune on the street but think it'd be fun to have a switch(red button?) In the car with that final moonshot tune saved to it. Like a maximum "smoke that Mustang" button.

Had to sell my Miata earlier in the year but I’m still a Miata bro at heart! Great videos, my man! I love your content, and your attitude, I can tell you really care about your viewers and the Miata community.
I do but it needs some updates, I'll have it done sometime this week. It's mostly accurate now minus the new turbo stuff thecarpassionchannel.com/vvt-mega-page
What specific turbo does he run? And is there any more dyno/info other than saying it's responsive? I haven't been following his stuff too closely lately. The Garrett GTX2860R is most similar in headroom to the two turbos tested here, anything with a GTX30 exhaust side is going to be more sluggish in trade for flow. The EFR "Gamma-Ti" turbine wheels are literally half the weight of the equivalent Garretts, the response is ridiculous
100% duty cycle on the injectors, does that mean theyre open 100% of the time? So also squirting after combustion, during the exhaust stroke, during the explosion etc?
I do believe that is true - but remember the fuel can't get into the chamber until the intake valve opens. So during the exhaust/combustion etc the injector is just loading up the back of the intake valve with the next fuel charge
Quick question, is the background of the thumbnail star wars or Space balls? I just realized while typing this the Tesla has both Ludacris and Plaid; which is from Space Balls. The questions is, which stage is the Miata at? Ludacris or Plaid? -Super Reaching Niche comment (Hahahaha)

the more you explain it and the more I think about it I think I may keep melting pistons due to fueling issues. 265whp/264lbfttq on mustang dyno on 15psi on a 2554r, so probably closer to 280ish. stock pump, stock rail, and rx8 yellow injectors.
