    More updates soon!

    So far as of now I have everything in parts and I’m waiting on my head and block to be machined. Forgot to mention but I’ll be running 2500cc of methanol split between each runner so direct port meth injection. I’ll have enough fuel there and hopefully be able to get some more air in and out from these Kelford cams with this kinda small BNR S5.

    Still on oem crank that’s non keyed and also the oem exhaust mani which I’ll get one from graveyard pretty soon too! Should be a fun build and hoping to get to 8k rpm and spool pretty fast and will keep yall updated once I get my block and head back!

    You don't really need all the head work and cams to hit 600hp. For what you're spending on all that plus a methanol kit you could get a turbo more well suited for your needs so you're not maxing out the bnr. From experience, methanol is more of a hassle than it's worth for fueling. Just get a good PI/fuel setup IMO.

    This is quite an overbuilt engine for your goals. I'm assuming (and hoping) that this was intentional? You're pretty much just a bigger turbo away from 800, and sleeves and 12mm head bolt threads away from 1000.

    Making 600 on a speed is extremely easy and cheap compared to a lot of what was done here (for anyone else interested in 600).

    I built the engine for 800 ish and yea I could go port injection but I had a whole methanol kit laying around from a previous build so ima put it to use. I’m hand porting the head too so I did intentionally overbuild the engine except for sleeves. Trying to hit that stock sleeve record lol

    I could have not built the head and still hit 600 easy, after this s5 I’ll get atleast a 6266 of a turbo and switch to port injection so it’ll be fun, I should get the block and head back here shortly! Regards to the focus st mani I’ve seen ppl crack them at around 900-950 around there so I’m not too worried about that either.

    Yeah, methanol is largely unreliable compared to port injection though, and on a build like this, I'd be very concerned running it. Takes one bad pull. To each their own. As for the ST intake manifold, they really don't crack unless you go north of 50psi. 40+ they're rock solid. It's not a HP limit, it's a pressure limit, but if you're running 40+ psi you should probably be looking at a more efficient turbo setup in the first place, though some might disagree. I've seen stock ST manifolds at 1xxx hp and higher.

    My question is what have you done to actually put any of this power down? 600hp is cool and all, but what are you going to do if you can't even use it? I'm talking clutch, axles, suspension, traction, things like that. If you do the boneheaded thing and smack a really grippy set of tires on but nothing else, you're one launch away from needing new axles (though launching isn't as cool as the hot boy ricer kids will lead you to believe, so hopefully you don't do that).

    I’ll get myself a 6266 or bigger around next year, I just had that meth kit laying around so ima put it to use, I have plenty of methanol too, I’ll switch over to port injection next year too. I’m just using what I have at the moment but yes I will be switching my turbo/fueling setup next year so a few months don’t worry . As for putting the power down, I have just bc Coilovers and some 255/35r19 Michelin Cup 2, I’ve just alwase bought either all season 4s or those and stood by them on all of our cars. It’ll put the power down, might need a more sticky tire but we shall see!

    I have all 3 corksport motor mounts so far and a clutch masters fx350 with a aluminum flywheel, it feels great like oem and has plenty of headroom for 500+ of tq so that’s fine, might get a fx400 for a lil extra force if the fx350 is too little. Other than that it’s a pretty simple build besides all the motor work, trying to future proof it when I go for that stock sleeve record and some high rpm action lol

    I got my head and block back from the machine shop, everything looks all good, I’ll begin to assemble the short block tomorrow and still waiting on my cams and valve springs/retainers from Kelford then I’ll assemble my head

    Get the CS exhaust manifold with vband and a Pulsar turbo + PI and let the magic happen. I would not trust meth. https://www.pulsarturbo.com/product/psr3584-gen2/ My pulsar was great. You can check out my build thread. I would 1000% recommend going with a PI system that is independent from the DI system and do e85 in the PI tank. Only way I would use the stock fuel system with PI is if you do a surge tank too. https://mazdaspeeds.org/index.php?threads/johnnytightlips-build-maximum-carnage.7025/ Buy once cry once.

    I think that’s going to be the route ima go, ima sell that meth kit for some extra monies. I got the short block done today too and yes a standalone sounds very appealing and I can get one ethenol R local witch would be so very nice to run too

    As for a manifold setup I would go with a cs mani but man they are a bit pricy and ima just wait for someone to sell one second hand or buy one new, we will see. I should be getting my cams and valve springs here soon from Kelford and will be able to assemble the head and get it all tied together

    I forgot to mention for fluids for my car, I’ve had this speed since it had 40k miles and I’ve ran Liqui Moly 5W40 Moly gen oil and a Wix 51516 XP filter in it too and Redline MT-90 for trans fluid and it has ran great before too much boost broke my piston ring lol. I will be using Valvoline VR1 10w30 convention for break in and also Valvoline VR1 10w30 synthetic for my oil because it works great as break in oil and great for flat tappet engines. I will also be using Tribodyn EX 75w90 Limited Slip for my trans fluid and trying that out. I’ll keep using the Wix 51516 XP filter.

    Not much of an update but I’m still waiting on my cams/valve springs from Kelford.

    The short block is all assembled and torqued to spec and ready to get the head to go on when I get it all assembled.

    Here’s a bit of an update, I got my cams from Kelford along with everything else, got my head machined and got the head hand ported 90% to valves on intake and exhaust. I have also got some brisk racing 3 step colder plugs and they will be gapped at .028. I did get my valve cover / timing cover / battery tray and pieces / intercooler piping all powder coated jungle cruise. Lastly I have bought a new DI wiring harness from Harness Performance and will be getting the coil tuck here soon too!

    This whole time I’ve been having trouble posting pictures of this whole big process but I will address that here soon after it’s all back together for yall!

    I just also have seen that Graveyard Performance and Alpha Injector Clinic have partnered up and are in the process of making higher flowing direct injectors with +30% +60% +90% higher flowing injectors. Whenever the prices come out with them I will be buying some for this build. Hopefully be able to run full pump E85 and disregard the methanol injection!

    Couple things:
    1. Are you sure about using 3 step colder plugs? Normally people on full corn run stock heat range, even up to 500 ish HP.
    2. Graveyard is a shithead and has stolen ideas and even suppliers from people previously. He also has no qualms working with Dramatune to hide each others fuckups.
    3. Didn't think it was possible to have completely custom injectors made for this platform that wouldn't cost a literal fortune
    4. Custom injectors are going to need (at least I think they will) custom timings, which as far as I know are not exposed on any tuning platform...Which means a $10k standalone will be required to use them, unless Cobb or VT want to put in the work for that (doubtful).

    Happy to be corrected on any point here.

    I have been using Brisk 1-2-3 step colder plugs before on my speed and they ran perfectly, it just allows be to run a bit bigger gap. I’ve always loved using them on other cars and for customer builds.

    I’m not hating on graveyard because I haven’t had bad experiences with them and bought from them before and got parts quick and easy without hassle so I don’t really have something to hate on them about yk.

    I also never though we would get bigger injectors but we shall see how they perform and the price and everything. Also yes running bigger injectors on a speed will need a lot more to tuning and there’s stuff we don’t have yet but if there becomes a big aftermarket support to bigger injectors, I’m sure Versatuner will accommodate to that, ik they have live tuning on there list to add too and more features soon.

    And of the Ethanol pumps, I live in Wilmington NC and there’s pumps near and in a hour vicinity which I don’t mind stocking up on for this weekend car! If yall have any recommendations for my build or wanna talk more, I love the support, I also like trying new things when it comes to this platform when I’ve never heard of other ppl doing the same.

    Don’t get me wrong, there is a lot of stuff that can be way better like the fuel system and turbo setup but that’ll get perfected of this year, I have my eyes set on running a CS exhaust mani and a pulsar 6466 so I’ll get all that sorted once the car is back together and get this car running more efficiently along with figuring out the fuel system too with y’all’s help!

    @Kri$py , I've had issues when the images are a .heic file. But there is no reason the images should not upload. Email them to me if you want me to check em out.

    Honestly start with stock heat range plugs

    We will see what the injectors do if and when graveyard delivers. Hope you didn't put down a deposit

    No I didn’t put down a deposit lol, but yea for plugs I’ve used all different gaps and different heat ranges and the car has acted the same, I’ve been down to .020 to .030 with stock heat ranges to step 3 colder plugs and my car ran perfectly when I went through testing with different brands and heat ranges, different material plugs too. I feel as you run a colder plug you get to run a bit bigger gap too. But the reason why I’m using these brisk plugs is just for the fact that I have them on hand same with all the other plugs I’ve tested.

    If you think that the car ran the same on all those different plugs and gaps you don't understand the function of a car well enough to be able to make that determination

    Stock heat range stock gap

    I’ll probably end of using the NKG Plugs (6510) I have too. But yea I do have autozone plugs and brisk and some hks and denso plugs on hand in all different heat ranges but whatever yall think right is what’s it’s going to be lol

    Also I need some insight on some good trans fluid, I’ve been running MT90 but I’ve heard of ppl using ford fluid or mixes of MT90 and MTL. For oil I’ve been using Liqui Moly Moly gen 5w40 since I got the car with 40k or so mileage with oil changed ever 5k miles and wix filters so that’s good. Lastly if yall had any recommendations for brake fluid/clutch fluid too!
