- Today you guys will finally get to see all the internal parts that I've spent over 3 months and thousands of dollars developing for the 3a92! The open deck block was sent to CNCWerx for a cylinder support system to be installed. This block modification is much better than a block guard or devcon block filler, the cylinder support system prevents the cylinders from deforming at Extreme Power levels. Everything for this little engine had to be custom built; Pauter rods, Traum Pistons, and the cylinder support system.

Did you say 500hp from a 3A92?
Holy making power Batman!
And I'm going to build the world's most surpising sleeper following your build. Great video, love what you're doing. 🤘
We use CSS for our Honda engines to hold alot of boost..CSS is a great alternative to full sleeves if your on a tight budget
4:42 is enough to make a grown man cry 😂 glad everything was unscathed
74hp with 3 cylinders! I knew it was a mirage engine! I had one as my first car in 2016!
Great little engines! if we could get some larger head studs in them, Im certain I could get to 500hp
This is soooo interesting! I drive my Mirage on track and I mainly focused on suspension and handling to make up for the lack of power.
What kind of suspension setup do you run? I'm looking at getting godspeed coils and ultra racing sway bars, as well as a bigger wheel setup. Not sure there are many other options.
@@suiboy7284 I have competed the car on just lowering springs, but I recently have switched to BC coilovers and did some tuning, found out the 4k/2.4k rate that came with the coilovers are too soft for the track so I'm now running 8k f/4k r just so it can still be streetable. I did have to ditch the front swaybar as the front roll became too stiff and tend to push.
Ultra racing bars, I have the front strut, front lower 4pt, rear lower 2pt torsion brace and rear sway. Wheel setup, 16x7 205/45's, around -2.5 camber front. Onboard vids on my channel, thanks ;)
Nice block. I've been eyeballing the Arctic Cat T660 engine for a swap in my Suzuki Carry. This seems like a great upgrade 😁
I have been thinking about playing with this engine and about 10psi. It would be cool if you made a video based around the megasquirt and shared a base tune file to play with :) Nice job on having the highest HP version of this engine in the world!
Thats a great idea! I was planning to do so once I felt my tune is where it needs to be. I'm getting close 🤞
If only there was an 81mm bore version of this engine. Or rather, an 81mm bore of anything that had a common layout with DOHC and high flowing heads. Why, you ask? Because of the semi-solid cast 4AGE pistons available from Toyota which are a factory part that's good for 600hp in a 4AGE.
The casting method ends up aligning the grain structure of the hypereutectic pistons very similarly to forging, so you end up getting the benefits of both cast AND forged pistons in the same unit. I figure you take that 600 and divide it by 4 to get ~150HP per piston, then multiply that by your piston count to get total potential "safe" output.
For a 3-cyl application, that's obviously 450HP. All with no piston slap, little to no blow-by, and not having to warm it up with soft driving before romping on it.
Take it easy on the hp. At this pace, you'll outgun an Evo....heh heh
The company provides quality workmanship, but they can not take 15 seconds to blow the swarf out of that engine 😂🇨🇦
Super interesting video, I wish I could find a block to design a high horsepower DOHC V4 design but sadly nothing exist.
Cool idea though!
Lancia fulvia v4 come to mind
Get a Yamaha V-max (motorcycle) engine as your base. Particularly the bigger and newer 1700cc version from like 09(?) and up

Can you do this to a f2 engine?
500 is insane
Why did you reduced the compression ratio? Couldnt you have used a carved piston to increase it at the same size?
I reduced the compression to 9.5:1 to make it a little safer at the high levels of boost i'm running. Now, if it's an na build with good fuel you can increase it
I am curious about that if it is possible to increase stroke of 3A92 with stock engine block? Can we increase volume of this engine by this way?
The 3a92 already has a long stroke 90mm and since I had to notch the block just to put new rods in I doubt you could stroke it further... Could probably increase the bore size slightly if you were willing to go with aftermarket sleeves
How much did this run you? I’ve got a 1.8l v6 I’m building and this just might be the solution to some issues I have!
Mine had to be developed, but they have pricing on their website for different engines
I want to build the engine in my mirage. What's the cost on the pistons and rods?
Do it! They were both about $700 a set
Ahhh I wonder how many people got their info from the guy Suraruk that claimed Vitara pistons in his 3A92? Maybe he modified them somehow. I don't know.
There is one or two pistons out there that could possibly work, like that eclipse cross piston. They don’t actually work once you try to match wrist pin and rod length though 😔
@@DirtGearTv Right I figured rods would need to be selected and resized at the least. I hope these cars become popular for tuners
I've designed my own CSS last engine I did is at 889 whp b18c Honda engine
What did you do to handle the heat of the engine when closing the deck? I would imagine this limits the fluids capacity to cool this engine properly and I don't believe I have seen you mention how your temperature has changed after closing the deck or what you did you ever come the increase in heat if present.
Great question, cncwerks does a great job of putting coolant passage holes in the same locations of the head gasket so it doesn't block any additional coolant passages. With my radiator i'm able to keep temps under 195F no matter how much boost i'm pushing
I was thinking of getting a Mirage
If I hit up Traum for the pistons and Pauter for the rods and gave them your specs, would it be any cheaper now to have them made since they've done it before? Also, I don't do builds, but if I were to give my engine builder guy these parts -> block, pistons, rods, and bearings to do the build, would there be anything else he would need (using my same heads, and head gasket, I presume)? Next, if I only have this done and did not do anything else to the engine (like turbocharging) what ballpark hp would I expect? Finally, if I did put in a turbocharger which one would you recommend. If you've already answered any of these in the comments, let me know and I'll look harder. Thanks.
Good questions. The purpose of doing the pistons, rods, bearings etc is for the engine to not come apart under power adders (supercharger/ turbo). If you were to do these mods without a power adder you'd actually loose HP because of the additional weight of the heavy duty parts. If you're looking for just some quick cheap power you can add a small turbo to the stock engine but I wouldn't exceed 10psi on the stock engine. Yes I successfully ran more without any mods but that's a gamble and if it's a daily you risk damaging it. If it's just for fun run it up more 😁
@@DirtGearTv So what range of psi could the new setup take with a turbocharger?
@@patrickminx6614 I regularly run 30psi in my setup, at 43psi I lifted the head 😬
@@DirtGearTv 👍
I have a question. I'm about to get a 2020 Mitsubishi Mirage and the engine they have in it is a 3a90 I believe. Would this fit and if not could I do what you're doing to this one to that? It's 74hp as well. Would this effect its gass efficiency? It's like 39mpg combined and I want the power/speed. I just don't want to lose that sweet mpg. Sorry if I sound stupid. I'm new to all this
A 2020 should be a 3a92 that's the 1.2L mitsu uses in the mirage. A 3a90 is just a 1.0l version but i've never hear of one used in a mirage. So yes you can certainly do what I did by adding a little boost. A small turbo with 7-10psi the stock 3a92 should be able to handle that power level. Mpg would stay the same if you're driving it like 74hp, if you use boost and drive it faster than stock mpg will drop 👍
@@DirtGearTvIn other markets like Japan, that engine was an option.
What headgasket are you running?
OEM. You can have a custom made with fire rings and all but the factory gasket has held up well to my abuse
Bro I seen you at Durham town few months ago on the GP track 🤟 I was with my gf on the roketa gk 32 with street tires 😅
Love it! Ill be back this year with a fully working machine and full boost this time 😈
the new 4efe
Hello I Come Form Thailand I want to know Piston Conecting rod Block guard For 500hp Where can I order?
How much did a build like this cost?
You could build this exact engine for under 5k
Where can I get this exact same setup at?
Can hit up my boys at cylinder support systems (CNC Werx). Pauter Rods, Traum pistons, King Racing bearings for toyota 1nz (i believe) 👊
@@DirtGearTv this kit is for the 1.2L 3 cyl stock engine ? Mine is a 2013 mirage
Can i know total cost plz ?
what issues have you encountered so far?
I can't keep clutches in one piece 😂
@@DirtGearTv is there a performance clutch available to accommodate that power?
I'd be happy with 170hp and high revs, maybe around 9000rpm
That would make a huge difference and is a reasonable goal for these. High revs are very stressful on rod bolts and mains, I believe the rods and pistons can handle this but would deff do main bolts and cap bolts 👍
High rpm 3 cylinder I don't know it is possible
@@GF-mf7ml there are motorcycle engines like that. Ducati
Good Sir I will have you know that a stock Mirage engine could make as much at 78hp, how dare you take that 4hp away from it haha , really cool block !
i thought it was a suzuki 1.0L from a Geo Metro looking at the thumbnail.
Right? These little 3a92s have been dubbed the “new” geo metro engines 😜
What kind of shit machine shop sends the part out with shavings all over it?!
wow forged pistons!
first on youtube maybe....
It took us months to develop... Pretty sure it's the first 😆
Transmission won't hold on up to that. Have plastic synchronizers
Now ya tell me!
How much money have you spent on this lol😅
Haha, you’re looking at about 3k in just this video! 🤕🤦🏼♂️
@@DirtGearTv I know the pain that comes with this addiction. Every penny, and every bloody knuckle is worth it.👍 The joy eases the pain.
@@DirtGearTv Damn. A 1000cc bike engine is cheaper and simpler for most projects. But it is really cool that you are pushing this engine to it's limits! And you will make a lot more power of course😁
If you have to ask you can’t afford it !!
